Climate Chain Coalition releases report on blockchain and emerging technologies at COP 27

The Climate Chain Coalition (CCC), a network of organizations dedicated to leveraging blockchain technology for effective climate action that includes Cointelegraph as a member, delivered its stock take report on Nov. 11 at the 27th United Nations Climate Change Conference, or COP 27, in Sharm El-Sheikh, Egypt. Founded five years ago, the coalition has been working on initiatives related to the consumption accounting system and greenhouse gas emissions accounting. Tom Baumann, chair and founder of the Climate Chain Coalition, stated:“During those years, the coalition has grown from 12 founding organizations to over 360 organizations in 69 countries. The coalition was founded on the ethos of blockchain and emerging technologies as an open distributed network where members self-organize into member-driven initiatives.”Climate Chain Coalition members at COP 27 in Egypt.The coalition’s mission is to resolve issues and challenges needed to advance transformative digital climate innovations by creating resources to support a shared data and digital infrastructure, supporting networking and capacity building, and partnering between digital and climate communities.Related: How blockchain technology is transforming climate action Cointelegraph editor-in-chief Kristina Lucrezia Cornèr speaking at COP 27 on blockchain’s relevance in fighting climate change.Speaking at the panel, Cointelegraph editor-in-chief Kristina Lucrezia Cornèr commented:“Education is key here, and media responsibility is incredibly high. We consider it our biggest mission to talk not only about what is intrinsic to the blockchain industry but what’s going on beyond. And because it’s out of the box that things are uniting us because this conference is about climate action, and climate is so much more [than] just climate change. It’s about sustainability, and it’s about our future.” Also participating in the panel, Alexey Shadrin, co-founder and CEO of Evercity — a platform for the management, issuance and monitoring of sustainable finance — highlighted how the coalition’s efforts are supporting organizations with use cases of implementing blockchain technology, as well as guidance to the new projects that are rapidly emerging right now in the markets. “We want to make sure that those projects are not only innovative and cool but also aligned with core UN values and standards that currently exist there and that were developed by many, many experts within the UN process and beyond.”Even though digital assets have been criticized for their high energy consumption, such an accusation is inaccurate, as there is a distinction between cryptocurrencies and the underlying blockchain platforms that can energy efficient and support climate initiatives.

Bitcoin miners rethink business strategies to survive long-term

The Bitcoin mining industry continues to face a challenging year as the price of Bitcoin (BTC) hovers below $20,000, coupled with rising energy costs in North America and Europe. Regulators have also recently started clamping down on crypto mining, as a recent report from the Bitcoin Mining Council (BMC) found that Bitcoin has seen a 41% increase in energy consumption year-on-year (YoY). As a result, a number of crypto mining companies have been forced to sell off equipment, while others have filed for bankruptcy. Yet, this hasn’t been the case for some miners, particularly those focused on clean energy solutions and strategic approaches. For example, in September, crypto mining firm CleanSpark announced an agreement to acquire Mawson’s Bitcoin mining facility in Sandersville, Georgia, for $33 million. The crypto mining company White Rock Management also recently expanded its mining operations to Texas.Why some Bitcoin miners are thriving in a bear marketMatthew Schultz, executive chairman of CleanSpark, told Cointelegraph that he views mining as a unique way to decrease energy costs when leveraged for reasons other than making profits. According to Schultz, this perspective has differentiated CleanSpark from other crypto-mining companies. “Bitcoin mining is a potential solution for creating more opportunities for energy development,” he said. Schultz elaborated that CleanSpark partners with cities in the United States, like Georgia and Texas, to buy excess energy. For example, he noted that CleanSpark works with local areas in Georgia that receive energy from the Municipal Electric Authority of Georgia.“These cities essentially become our utility provider. They make a margin on every kilowatt hour we buy to conduct our mining operations. Yet, we are buying such high quantities of energy that it brings down energy costs for the communities we work with. We aim to impact cities posivetly by driving energy costs down,” he said.CleanSpark CEO Zach Bradford inspects a mining pod with techs at the company’s College Park Bitcoin mining campus. Source: CleanSparkSchultz also pointed out that CleanSpark formed a partnership with the energy company Lancium to support their data center in West Texas by buying excess renewable energy to create grid stability. As a result, Schultz shared that CleanSpark currently has half a billion United States dollars worth of assets on its balance sheet and less than $20 million in debt, along with support from investors like BlackRock and Vanguard. Given this, Schultz believes that the crypto bear market has impacted CleanSpark differently in comparison with other crypto miners. For instance, he noted that when one Bitcoin was worth $69,000 a year ago, many miners were discussing plans to hold BTC. “These miners also made huge commitments to companies like Bitmain for the future delivery of mining rigs,” he said. Yet, according to Schultz, CleanSpark conducted extensive analysis of the number of mining rigs being ordered last year while also looking at future energy projections. He stated:“We reached the conclusion that rather than sending a deposit for mining equipment to providers last November that are just now being delivered, we saw the possibility of an oversupply of rigs and an increase in energy costs. Therefore we sold Bitcoin when it was in the $60,000 range and invested proceeds in infrastructure instead.” Not only did this allow CleanSpark to acquire its new mining facility in Sandersville, Georgia, but Schlutz also noted that the firm is currently purchasing Bitcoin mining rigs at a very low rate. “We are buying rigs for $17 per terahash that one year ago cost $100 per terahash.”As a number of miners are forced to sell their equipment, both used and new mining rigs are being sold at below market prices, creating buying opportunities for firms like CleanSpark. Scott Offord, owner of Scott’s Crypto Mining — a service that provides new and used mining equipment, along with mining training courses — told Cointelegraph that prices for miners are now very inexpensive, partly based on a lack of demand due to the low price of Bitcoin. Offord added that many of the used miners he is currently selling have come from hosting facilities in debt. He said:“During the last bull run you couldn’t get miners without a 6-month lead time. It’s the opposite now since many miners aren’t capitalizing. Usually, Bitcoin miners get rid of their gear because equipment is old and something newer is on the market, but it seems like now people are selling because they need cash flow.”Offord also pointed out that he is seeing a lot of new mining gear hit secondary markets. “Many new generation Antminers are being resold. For example, things like S-19s, which are some of the most efficient miners in the world right now,” he said. In terms of pricing, Offord explained that crypto miners may be able to buy a new Antminer S-19j pro for about $20 per terrahash. “This same machine would have cost three times as much with a three-month lead time one year ago,” he added. Echoing Offord, Andy Long, chief operating officer of Bitcoin mining firm White Rock Management, told Cointelegraph that miners who are selling equipment are generally doing so to cover debt payments for hardware bought when prices were higher. “Hardware is now being bought by well-capitalized miners and will continue to be used to secure the network,” he said. White Rock Management Texas Mining Site. Source: White Rock Management According to Long, White Rock Management’s operations in the United States have not been impacted by the bear market, adding that its facility in Texas operates completely off-grid. “White Rock’s U.S. operations are powered by flared natural gas, while our mining operations in Sweden are also 100% hydroelectric powered.”Bitcoin miners rethink business strategiesWhile miners like CleanSpark and White Rock Management continue to grow, others may need to rethink their business strategies. Elliot David, head of climate strategy and partnerships at Sustainable Bitcoin Protocol — a green Bitcoin mining certification protocol — told Cointelegraph that he believes conditions for miners are going to get worse before things improve. “Miners that want to survive the long term will have to change their strategy,” he said. Indeed, some miners are making adjustments. For example, Jonathan Bates, CEO of crypto mining firm BitMine, recently mentioned in a press release that due to the sharp decline in mining rig prices, the firm will currently only focus on self-mining rather than hosting for others. “Given the sharp drop in ASIC prices, we feel that focusing on self-mining is a better use of our datacenter equipment and a better use of firm capital at this time,” he stated. He added that the firm plans to “pursue joint ventures and partnerships where our infrastructure equipment can be paired with ASIC miners valued at current prices.”The press release further noted that on Oct. 19, Bitmine entered into a repurchase and hosting agreement with The Crypto Company (TCC), a publicly listed blockchain company. Under this agreement, Bitmine agreed to repurchase certain ASIC miners previously sold to TCC while also purchasing additional ASIC miners owned by TCC. Bitmine will also terminate the hosting agreement that it had established with TCC. To be specific, Bitmine sold TCC 70 Antminer T-17s for $175,000, along with 25 Whatsminers for $162,500, for a total purchase of $337,500 during February this year. Simultaneously, Bitmine and TCC entered into a hosting agreement under which Bitmine agreed to host the miners, along with other miners owned by TCC. Due to current conditions, it’s been noted that Bitmine will accept the return of the 70 Antminer TY-17s for a credit of $175,000 as a warranty claim. Bitmine will also purchase the 25 Whatsminers for $62,500 and the 72 Antminer T-19s from TCC for $144,000. This marks a significant decrease in price from when the units were initially sold.In 2021 — during the height of the crypto bull run — Bitmine entered into an agreement with a telecommunications company located in Trinidad and Tobago. The agreement allows Bitmine to co-locate up to 125 800-kilowatt containers for hosting miners over 93 potential locations. Bitmine is also able to co-locate containers at its own pace, paying a fixed amount per container, along with the electricity costs incurred by its containers. At the time of the agreement, Bitmine noted that the electricity rate expected to pay for the hosting containers was $0.035 cents per kilowatt-hour. This was based on the rate currently paid by the telecommunications company. In October of this year, Bitmine completed the installation of its initial hosting containers in Trinidad. However, prior to commencing operations, Bitmine shared that the telecommunications company advised that the electric company would not honor its existing agreement and instead indicated that the rate would be approximately $0.09 per kilowatt-hour. Although the telecommunications company has protested this decision, Bitmine has chosen to delay the installation of additional containers in Trinidad until the dispute is resolved. The future of crypto miningGiven recent changes being made by miners, David believes that the crypto-mining industry is approaching a junction. “Miners will need to diversify their revenue streams,” he said. With this in mind, he explained that there has been growing interest from clean energy miners that want to work with Sustainable Bitcoin Protocol to ensure sustainable mining practices as a way to be more financially resilient.Echoing this, Offord mentioned that he is seeing more interest from miners regarding their environmental impact. “Miners are seeking opportunities in places where there is flare gas that needs to be mitigated, or where biofuel is being created from farm waste. Miners are not just focused on building a Bitcoin mine, but want to build something sustainable that can be carbon negative.” In addition to sustainability, David pointed out that regulations are becoming more important than ever before for crypto miners. He noted that this is especially true within the United States, noting:“The industry in the U.S. is becoming increasingly aware that unless they regulate themselves that the various levels of government might step in. I’ve spoken with a number of policymakers and staffers, and in a crunch the Bitcoin mining industry will be a likely first target.”

Bitcoin mining in Norway gets the green light as the proposed ban rejected

There’s Nor-way they can ban Bitcoin (BTC) mining in Norway now. That’s according to a majority vote passed by the Norwegian parliament on May 10.The proposal to ban Bitcoin mining in Norway was first suggested in March this year by the Red Party (Norway’s communist party.) In this week’s vote, the proposal was overturned as only Norway’s left-leaning parties, including the Socialist Left Party, the Red Party and the Green Party would support a ban on cryptocurrency mining.Jaran Mellerud, an Analyst at Arcane Research and a Cointelegraph confidant shed light on the developments: “The vote these parties lost was against banning large-scale Bitcoin mining overall.”“Having lost this vote, these political parties will likely make one more attempt at increasing the power tax specifically for miners, which is now their only tool left in the toolbox for making life difficult for miners.”Contrary to the political parties’ efforts, Bitcoin mining companies in Norway have thrived in recent years. Norway now contributes as much as 1% to the global Bitcoin hash rate, taking advantage of 100% renewable energy in the Land of the Midnight Sun.Norwegian Mellerud added that “Bitcoin-hostile political parties in Norway have been trying to force bitcoin miners out of the country by implementing a higher power tax rate specifically for miners or even attempting to ban mining.”Luckily, they haven’t been successful, and this decision by the government to not ban bitcoin mining should be the latest nail in the coffin for their attempts to get rid of the industry.Cointelegraph previously reported that Norway is a “green oasis” for Bitcoin mining, boasting abundant hydropower and low energy prices, particularly in the north. In mid-northern and northern Norway, the cost per kilowatt-hour is 0.12 Norwegian Krone ($0.012), a highly competitive rate internationally, or “extremely cheap,” Mellerud told Cointelegraph.Related: Water great idea! Bitcoin mining heats this swimming poolThe article from Norwegian news E24 reported that “ordinary households, companies and the public sector pay an electricity tax of 15.41 øre ($0.015) per kilowatt-hour,” however, in some cases the “mining industry has a reduced electricity tax.” Mellerud concluded that “an increase in the power tax specifically for miners is now much less likely.” Meanwhile, Bitcoin is slowly entrenching into the Norwegian financial landscape as retail interest in cryptocurrencies swells and TradFi companies have dipped their toes into BTC investments in the country.

Decentralizing the grid: Operators test blockchain solutions

The world’s energy market is rapidly evolving, moving from hydrocarbon plants to a future centered around clean energy enabled by wind and solar power. As such, today’s energy market is shifting to an increasingly decentralized, real-time model based on distributed energy resources (DERs) including battery energy storage systems, solar arrays, natural gas generators and more. Recent findings from Allied Market Research show that the global distributed energy generation market size was valued at $246.4 billion in 2020, yet this number is predicted to reach $919.6 billion by 2030. Web3 technologies for managing energy assetsGiven today’s advancing energy market, Jesse Morris, CEO of Energy Web — a nonprofit that develops operating systems for decentralized energy grids — told Cointelegraph that grid operators around the world are moving to systems in which customer-owned assets will be used to balance energy grids. “Technology that was previously located within physical substations including monitoring equipment is now spread across the distribution network as the number of DERs increases,” said Morris. While this shift is innovative, Morris pointed out that regulated companies remain unaware of how to manage a decentralized system. With this problem in mind, Morris explained that Energy Web recently formed a partnership with Stedin, a Dutch distribution system operator (DSO) that caters to the province of South Holland and in parts of North Holland and Friesland to use a blockchain solution for managing distributed energy assets. According to Morris, Energy Web’s solution allows for energy assets to communicate directly with Stedin’s IT systems:“Stedin is using Energy Web’s tech stack and Web3 technologies to establish a digital relationship with customer-owned assets, along with creating a secure, asset management system for their own controlled assets. This is the first instance I’m aware of where an enterprise is using Web3 technology to manage their own physical infrastructure and assets.” Specifically speaking, Morris explained that Energy Web’s blockchain network is being combined with decentralized identifiers (DIDs) to provide digital identities to Stedin’s internal and customer-facing energy assets. “The joint Energy Web-Stedin solution currently comprises a management system which assigns each distribution asset a secure digital identity, or DID, anchored on the pre-existing SIM card in each asset,” said Morris. Once this has been enabled, Morris noted that Stedin is able to send cryptographically signed information and control signals or commands to and from an asset. “This creates a decentralized managed system by ensuring that each asset operates as an independent point of encrypted security,” he remarked.Shedding light on this, Arjen Jongepier, innovation head at Stedin, told Cointelegraph that Stedin was seeking a general asset management solution given the evolving energy market: “In this case, we required supplier agnostic registration of Internet of Things (IoT) assets via our SIM cards. We anticipate a number of benefits from this, including easier and fewer-step installation of IoT assets, increased data reliability and, in the near future, local prosumer interaction, which could involve home energy storage systems and EVs being able to sell energy back to the grid.”Digital identity enables greater cybersecurity and data ownershipWhile this use case speaks volumes about how the future of the energy market may take shape, the application of DIDs ultimately enables better cybersecurity for grid operators. For instance, when compared with traditional Web1 or Web2 approaches, Morris explained that most grid operators use a centralized database to manually enter information about sensors or hardware located on utilities within their network. Yet, such an approach could allow for grid operators to collect user data and even gain control of those sensors. “This level of centralization is a cybersecurity risk, which is why our solution with Stedin also proves to be a cybersecurity application,” Morris remarked.Jongepier added that Stedin was indeed looking to raise the bar on its cybersecurity. “Blockchain is effective for this because it provides the ground rules for utilizing decentralized identifiers for Stedin’s IoT assets, serving as a solution for raising the bar on security.” This is an important point, as Morris shared that the primary difference between Stedin’s application of Energy Web’s solution versus previous implementations is that it demonstrates enhanced cybersecurity using DIDs.Sam Curren, decentralized identity architect at Indicio — an organization that works with governments and businesses to integrate DIDs in their systems — told Cointelegraph that the purpose of a DID is to provide a unique identifier in which ownership or control can only be proven by the possession of a private key. In the case of Stedin, Morris explained that Energy Web is responsible for private key storage and making sure that user administration is fully decentralized. Given this level of decentralization, Curren noted that applying DIDs for energy assets is more secure than storing information in a database where data can be easily accessed by administrators and potentially manipulated.Using DIDs for energy asset management and security also demonstrates the notion that current energy grids are undergoing an ownership question similar to what the internet is facing with the rise of Web3. For instance, Morris pointed out that grid operators can take a decentralized open-source approach to energy asset management or allow large companies like Google to manage their infrastructure in the future.Roscoe wind farm in Texas. Source: Matthew T RaderWill decentralized solutions appeal to grid operators?Given that there are other options available when it comes to DER management, this may lead some to wonder if large grid operators will actually want to pursue a decentralized approach. For instance, Paul Brody, global blockchain lead at EY, told Cointelegraph that where centralized grid operators already exist, the demand for decentralized systems may not be high:“Regulators will not be comfortable with allowing people to cherry-pick their access to the grid or allowing the grid to hollow out, as these systems are cheapest for everyone when everyone uses them. We’re already seeing issues like this affecting parts of the U.S. with very high solar panel penetration. While some trials are happening in mature markets, it is likely that the biggest demand will come from parts of the world without grids or reliable grids.” Jongepier further shared that Stedin had to go through a learning cycle to understand blockchain, its operations and its use case in order for Energy Web’s solution to be implemented: “The IoT team actually challenged the idea of using blockchain as opposed to progressing with more common, centralized solutions. With any new technology, it’s important to continually challenge it against the current solution and decide where it can most effectively be implemented.”Yet, in terms of effectiveness, Jongepier explained that Stedin’s technology team found that decentralized solutions enabled by blockchain are the most suitable for prosumer interaction in the future. It’s important to note, though, that the joint Energy Web-Stedin solution is currently undergoing rigorous testing within a sandbox environment. “It is expected that this sandbox will run for the duration of Q1 before the solution goes live later this year,” said Morris. In the future, Morris hopes that this specific project can be adapted for other energy grids in partnership with national DSOs to improve asset security and management. But, Morris is aware that this may take years to play out, given regulatory challenges, along with blockchain’s misunderstood reputation with enterprises. “People often think that all blockchains inherently have very high energy consumption, when that’s not true, along with associations with crypto-price volatilities negatively affecting the image of blockchain and token stability,” mentioned Jongepier. Morris added that solutions such as this one only make sense if prosumer energy assets like EVs and photovoltaics are able to participate in energy markets. “In many geographies across the world, they are not, so until this regulatory challenge is solved, our technology stack will remain limited.”

Seven times Bitcoin miners made the world a better place

What do a swimming pool, beef jerky, a caravan, timber, animal waste, a Guatemalan lake and a high school have in common? They’ve all been saved by Bitcoin (BTC) mining. From reusing “waste” heat to getting the job done — to receiving a cool blast of air to dehydrate meat, to cleaning up pollutants, Bitcoin mining does more than just secure the network. Here’s a round-up of seven times Bitcoin mining lent a hand or simply made the world a better place.Free Bitcoin mining education in WashingtonSustainable Bitcoin mining company Merkle Standard has taken Bitcoin mining education into its own hands. In partnership with Bitmain, they recently gifted the latest in Bitcoin mining technology to Newport High School, a high school in Washington state. Plus, they donated $10,000 and are promoting education about Bitcoin in the hope that it will, “plant a seed that encourages lifelong interest in blockchain and digital mining.”Along with the check, Ruslan Zinurov, Merkle Standard’s CEO, told Cointelegraph that they will also invite students to their “data center to check on their machine that is hashing to their school’s wallet.” Zinurov told Cointelegraph:“It is our top priority to get the community excited about Bitcoin and we can’t think of a better way to do this than to educate the local students.”Adam Delderfield, business development manager at Bitmain — the holding company for the Antminer Bitcoin miners — told Cointelegraph, “Digital currency mining proceeds from this gift will go directly to education,” adding that “Bitcoin mining and proof-of-work represent an exciting new industry that opens up numerous new opportunities.”Adam Delderfield from Bitmain in the suit, and Monty Stahl from Merkle Standard with the students.

They told Cointelegraph, “Bitcoin miners have one hell of an excess of supply of dry, heated air,” so it makes sense to funnel that heat over strips of beef to make jerky. Good temps for jerky so far #Bitcoin pic.twitter.com/0WPnTuNwnF— ₿usiness Cat (@_business_cat) April 4, 2022Similar to Merkle Standard, for the Business Cat, the jerky cooking process is not about making money: “My normal food dehydrator uses much less energy than an S9, but hashpower dried jerky just tastes better.” They told Cointelegraph that “the support of the plebs on Bitcoin Twitter” persuaded them to try out the idea. They joked that “most of us [Bitcoin plebs] are natural loners, so a few words of praise or support from others on the path goes a long way.” The Bitcoin community is increasingly supportive of ideas that promote Bitcoin philosophy and Bitcoin-only ideas, from a Bitcoin hostel in Portugal to a Bitcoin lake project in Guatemala.

Bitcoin miner to the rescue!Michael Schmid is a well-traveled, savvy Bitcoiner. When his caravan’s propane gas heater broke down, he refitted the vehicle to be warmed by the “waste” heat from an S9 Bitcoin miner.Schmid told Cointelegraph that he saves “around 50% of the propane costs, which is around $2.7 per day.” “Now the fun part, the miner produces around 0.00006259 BTC per day (with the current difficulty and 13 TH/s) on the current price of 38 thousand. This is $2.40 per day, so we technically heat the airstream for free.”Schmid’s airstream kept warm with a Bitcoin miner, in a box just behind the wheel. Source: SchmidPlus, a kick in the teeth to the anti-Bitcoin environmentalists — heating the Schmid family airstream with Bitcoin rather than propane gas is better for the planet. “Our Airstream has solar panels on top of it that can generate up to 400W of energy, so technically of the 1400W that the miner uses, 400W of them are self-generated and fully renewable.”Bitcoin miner waste heat dries out timber Kryptovault is a Norwegian Bitcoin mining company with arguably the greenest credentials among any industry. Powered by 100% hydropower, the energy it uses solves valid blocks on the Bitcoin blockchain and the heat generated by the miners blows over damp logs from a local timber mill.Timber waiting to be dried by Bitcoin miner’s waste heat at Kryptovault’s mining facility.

Kjetil Hove Pettersen, CEO of KryptoVault, told Cointelegraph that drying out seaweed for local companies is coming soon, and they are “constantly looking for new ways of utilizing our waste heat.”Pettersen explained, “Approximately 99% of our electric energy turns into thermal energy.” “ As we know, energy is never truly lost, it only changes form. So this is a way of us to utilize this energy twice and support other local industries in the process. I can’t think of any better industrial use-cases than what we are doing.”Promoting financial and energy autonomy in Guatemala In south Guatemala, a team of Bitcoin miners donated an S9 to the local mayor and the mining proceeds are being used to repair a wastewater treatment plant. Bill Whittaker and Patrick Melder, on the right, installing the Bitcoin miner.

Sustainable Bitcoin miner uses waste heat to dry wood

Norway is a bastion for renewable energy management in Europe. As much as 99% of Norway’s energy derives from hydropower while the grid often enjoys a green energy surplus. But for Norway’s largest data center and Bitcoin (BTC) miner, Kryptovault, using regenerative hydropower to attempt to solve valid Bitcoin blocks was not enough. At the Hønefoss Bitcoin mining operation, which employees have aptly named “the Cathedral” due to its vast and cavernous expanse, the hot air generated by Bitcoin mining rigs is recycled and used to dry out chopped logs.Kjetil Hove Pettersen, CEO of Kryptovault, told Cointelegraph that Norway is an “ideal location for mining” and that alongside the log-drying operation, seaweed drying operations will kick off in the first half of 2022.According to Pettersen, Norway has a lot of “trapped” energy, pointing out to a much higher production compared to consumption as well as a limited capacity to transfer the excess energy:“This translates to very low energy prices and we can ‘rescue’ that trapped energy rather than letting it go to waste.”It would appear that the withdrawal of electricity subsidies from Bitcoin mining farms in 2018 has not affected the Scandinavian country’s status as a sought-after destination to mine cryptocurrency. The Guardian newspaper, which typically asserts Bitcoin mining energy-FUD, flipped the narrative while reporting on Kryptovault’s operation. Their article considered “can Bitcoin be sustainable?”Svein Bjerke, General Manager at the timber company that receives the dry logs, answers that question. In a video, Bjerke says that drying wood with waste heat from Bitcoin mining is the “most environmentally friendly way to do this.”Moreover, the secondary benefits of Bitcoin mining branch out to more than the environment. Over time, Hønefoss grid customers are actually better off due to the presence of Kryptovault’s energy-hungry process. Grid fees–like trees–are hacked down year after year because the local area’s total energy consumption increases. The more energy is used, the more prices come down over the long term. The company estimates that circa 2 million Euros is saved due to “Kryptovault’s existence in our grid.” Nonetheless, the route to mining 100% green and renewable Bitcoin has not been easy. Numerous challenges face miners in Norway, including:“Project and engineering perspectives to financial challenges, involving banks, tax and regulatory compliance. Just the step of setting up a bank account when working in this industry can be a large challenge today.”Related: EU securities regulator calls for proof-of-work crypto mining banUnphased, these hiccoughs are unlikely to hinder Kryptovault’s vision to transform clean energy into Satoshis. Pettersen says he “can’t think of any better industrial use-cases than what we are doing.” When asked by Cointelegraph if Kryptovault would consider mining other cryptocurrencies in the future, Pettersen jokes, “for us, Bitcoin is the name of the game.”

Bitcoin miners believe global hash rate to grow ‘aggressively’

Bitcoin (BTC) seems to be on everyone’s mind lately as the world recently witnessed the price of BTC take a rather unexpected bearish turn this month. On January 21, 2022, Bitcoin reached six-month lows, sinking below $40,000 for the first time in months. While some panicked, other industry experts pointed out that the Bitcoin network has become verifiably stronger than ever before. The growth of the Bitcoin network has become apparent, as hash rate figures for BTC continue to set new highs this month. For example, on Jan. 22, the BTC network recorded an all-time high of 26.643 trillion with an average hash rate of 190.71 exahash per second (EH/s).The hash rate will continue to grow, which is a good thingSamir Tabar, chief strategy officer at Bit Digital — a publicly listed Bitcoin miner — told Cointelegraph that the BTC hash rate refers to the amount of computing power being contributed to the network at any given time. Tabar explained that when it comes to Bitcoin mining, a higher hash rate equates to a good hash rate. “The more computing power going towards maintaining a network, the more secure it will be and the more transactions it will be able to handle,” said Tabar.As such, the recent hash rate figures for Bitcoin are extremely notable, even with the price of BTC being down. Peter Wall, CEO of crypto mining firm Argo Blockchain, told Cointelegraph that he wasn’t surprised to see the BTC hash rate hit close to 200 EH/s. Wall further stated that even with events that have recently disrupted BTC mining hash rate like the political upheaval in Kazakhstan, the hash rate will continue to grow higher each month:“Argo Blockchain’s mining margin last year in 2021, which is our revenue minus our direct costs, was over 80%. It was a very good year for miners. In 2020, where BTC prices were much lower, our margin was 41%. So, this year I think we will still see strong margins in the space despite the recent drop in the price of Bitcoin and the increase in the hash rate.”Darin Feinstein, co-founder and co-chairman of Core Scientific — a major publicly-traded blockchain infrastructure provider — told Cointelegraph that based on previous Bitcoin mining hash rate data, the BTC network grew by 200% following the mass exodus of miners from China:“The Bitcoin network one year ago was approximately 143 EH/s. Following the mining ban in China, the network fell to 63 EH/s. Today, the hash rate has grown to approximately 198 EH/s. This recent increase represents three important metrics. One, it represents a 130 EH hash rate increase on the network. Two, it represents 130 EH of new hosting infrastructure and primarily new generation hardware deployment and three, this deployment has taken place in geographic regions that use far cleaner energy than the energy used in China.”With this in mind, Feinstein noted that even though the BTC network has hit all-time highs in terms of EH/s, due to the massive improvements in miner chip technology and geographic distribution away from China, the network is now the most efficient and sustainable than it has ever been. Feinstein added that this data is important because it shows how much energy every terahash uses, which is generally represented by a metric called jules/terahash. He noted that this ratio has fallen greatly over the last several years, demonstrating a major increase in mining energy efficiency.Bitcoin mining efficiency chart. Source: Darin FeinsteinWill infrastructure support network growth?Michael Levitt, co-founder chairman and CEO of Core Scientific, told Cointelegraph that he fully anticipates for the BTC global hash rate to continue growing at an aggressive pace.However, Levitt mentioned that this growth is dependent on the price of Bitcoin moving forward, along with the success of the infrastructure currently being built. “The amount of infrastructure expected will be challenged by global supply chain issues,” he remarked.Feinstein added that infrastructure is the biggest challenge when it comes to mining Bitcoin. “The bottlenecks for Bitcoin mining are land, energy, equipment, and lastly, infrastructure. There is plenty of ASIC hardware to be purchased, energy and land are also readily available, but miners need a place to plug in power, and, historically, that is where miners run into issues,” he commented.North America has become one of the world’s largest Bitcoin mining hubs, as per data from the Cambridge Bitcoin Electricity Consumption Index, which shows that 35% of the average monthly BTC hash rate comes from the United States, while 10% comes from Canada. Wall explained that North America has taken the lead as a global Bitcoin mining hub for a number of reasons. “This is the case due to the region’s crypto-friendly jurisdiction, its stable regulatory environment, pro-innovation nature and, most importantly, access to the most important thing miners need — low-cost power, preferably renewable.”Wall elaborated that the low costs of power in the U.S. have been significant for miners, especially when organizations tap into the right part of the power grid. “We’ve seen significant growth in Texas over the last 12 months,” he said. Cointelegraph previously reported that the Bitcoin mining industry in Texas consumed around 500 to 1,000 megawatts (MW) of power during Nov. 2021. The Electric Reliability Council of Texas reportedly anticipates that demand could increase as much as fivefold by 2023 and has planned an additional 3,000 to 5,000 MW.Wall elaborated that many miners are moving to Texas due to the fact that the state operates its own power grid that consists of a high degree of power from sustainable generation sources, but needs more flexible demand, or load:“Miners can provide a consistent load that is flexible. It’s also helpful that Texas has demand response programs in place, where miners will shut down and give power back to the grid when there is high demand. This makes the grid more resilient.”Benefits such as these have prompted Argo Blockchain to build its next 200 MW facility in Dickens County, west Texas, directly next to a 5.5-gigawatt substation. “There is a lot of congestion at that substation and they need local load to relieve it. The power from west Texas needs to go a long way to reach major urban cities like Dallas and Houston. But, if we can use that energy much closer to where it’s being generated, that relieves the congestion,” remarked Wall.By drawing power from a nearby substation, Argo Blockchain is demonstrating the use of sustainable energy. According to Wall, the mining company has been carbon negative since 2020. This is important, as Tabar stated that a massive environmental, social and governance movement is currently facing the crypto mining industry:“Miners must draw from clean sources of power or else they will be regulated out of business. It can’t always be about the cheapest sources of power. Miners will eventually suffer valuation discounts if they use dirty power, even if that source is cheap.”The perks of going publicA rush of mining firms to go public is another trend the Bitcoin mining industry is likely to witness this year. Most recently, Texas-based Bitcoin mining company Rhodium announced plans to offer 7.69 million shares at $12–$14 each in an initial public offering (IPO).Core Scientific went public on Jan. 20 after merging with Power & Digital Infrastructure Acquisition in aSPAC transaction. Although shares of Core Scientific have fallen since then, Feinstein mentioned that every publicly listed crypto company — like Coinbase, Galaxy Digital and others — brings institutional investment opportunities to the U.S. market. “This is enhancing and bringing credibility to the entire industry,” he remarked.Levitt added that Bitcoin miners going public brings about a number of benefits, including better access to capital while having publicly traded equity that can be used for acquiring and building other businesses. Moreover, Levitt added that having a public presence is useful for conversations in and around the financial services industry. “However, the principal benefit is much more ready access to capital for growing and developing our business,” said Levitt.

Enterprise blockchain to play a pivotal role in creating a sustainable future

Bitcoin (BTC) is often used to criticize all blockchain-based projects. This is understandable since Bitcoin was the first project to use a blockchain, is arguably the most recognizable and is the largest cryptocurrency by market cap.In the first half of this article, I will use Bitcoin as a proxy for all blockchain-based projects because most people associate blockchain with Bitcoin. Anything environmentally positive that can be said about Bitcoin will be doubly true for the vast majority of newer blockchain-based projects since Bitcoin uses the oldest version of blockchain technology.Blockchain energy consumptionBitcoin has been attacked for high energy consumption. Headlines pointing out that Bitcoin’s electricity usage is comparable to a country’s total consumption is a popular critique. Comparisons are useful, but they can have a deceptive framing effect. For example, the statistics most often cited in these attention-grabbing headlines are taken from the Cambridge Center for Alternative Finance (CCAF). The same organization also points out that transmission and distribution electricity losses in the United States could power the entire Bitcoin network 2.2 times. Always-on electrical devices in America consume 12.1x more energy than the Bitcoin network.So, the Bitcoin network uses as much electricity as a small country or far less than one sliver of America’s energy budget. Is that a lot? It depends on how you look at it.Related: Is Bitcoin a waste of energy? Pros and cons of Bitcoin miningAnother often used critique is that Bitcoin’s electricity consumption is growing so rapidly that Bitcoin emissions alone could push global warming above 2°C, or consume all of the world’s energy by 2020. The latter didn’t happen. Why? First, like most network-based technologies, Bitcoin is following an adoption curve defined by the theory of diffusion of innovations — an “S curve.”The explosive, exponential-like growth in the first half of the curve slows down considerably in the latter half. Second, large and predictable improvements in computer efficiency will continue to lower the energy cost of computing even as Bitcoin’s growth slows. Third, such predictions don’t take into account the evolving energy mixture of Bitcoin.Blockchain energy mixtureAlmost all of the energy consumed by blockchain projects come from electricity used by computers that secure the network. Bitcoin calls these “miners,” but newer blockchain projects can use much more efficient “validators.” Electricity is produced from many different sources, such as coal, natural gas and renewables like solar and hydroelectric. Those sources can create very different levels of carbon emissions, which largely determines their environmental impact. The two most prominent estimates of Bitcoin’s energy from renewables range from 39% in this report to 74% in this report. Either of these estimates is “cleaner” than America’s energy mixture, which is just 12% from renewables. There is evidence that the public scrutiny to which Bitcoin has been subjected has most likely ensured that energy from renewables will only increase in the future. Blockchain is worth itBitcoin’s energy consumption and composition are not perfect, nor is it as terrible as is often reported. What is often lost in the conversation over Bitcoin’s energy usage is whether Bitcoin’s use of energy is worthwhile. Plenty of industries require energy or produce massive amounts of waste, but most people deem the environmental costs to be worthwhile. The agricultural industry requires massive outlays of fossil fuels for fertilizers and to power field equipment, not to mention producing harmful runoff. Yet, despite the environmental negatives, we recognize the overwhelming importance of growing food. Instead of discarding agriculture, we strive to improve the environmentals of agriculture.Related: Green Bitcoin: The impact and importance of energy use for PoWWhether enabling the 1.7 billion unbanked to gain financial inclusion or offering an alternative to predatory international remittance services, it seems clear to me that Bitcoin is worth the energy usage. It’s even clearer that enterprise blockchain is an unmitigated public good. Newer, alternative blockchain technology uses at least 99.95% less energy than older ones. Enterprise blockchain can use even less energy since it can be tailored for specific use cases. In addition to using significantly less energy, Enterprise blockchain is helping organizations achieve sustainability goals. Blockchain as a key driver for renewable energySolar and wind are now cheaper than fossil fuels such as coal and natural gas. Solar and wind are now comparable to geothermal and hydroelectric. Despite solving the cost problem, renewables have several problems preventing mass adoption. Geothermal and hydroelectric are geography bound. Solar, wind and to a lesser extent, hydroelectric suffer intermittency and grid congestion. Intermittency means they are currently too unreliable. There’s no sun at night, the wind sometimes stops, and there are rainy and dry seasons. Grid congestion is similar to car traffic. Due to geographic constraints, renewables are usually built in rural areas. However, most energy is needed in dense towns and cities. Like a car in a traffic jam, the electricity is delayed getting to its destination.There are solutions, such as building battery storage and increasing transmission capacity, but these are expensive infrastructure projects. This is where Bitcoin, and blockchain, in general, can help. Unlike Bitcoin miners and other blockchain projects can be built anywhere. They’re profitable businesses so they can essentially subsidize the building of renewable infrastructure by always using excess energy produced. Related: No, Musk, don’t blame Bitcoin for dirty energy — The problem lies deeperAnother promising energy technology well suited to blockchain is person-to-person (P2P) electricity trading. These energy sharing schemes provide electricity suppliers and consumers with the opportunity to trade energy without the need for existing third-party intermediaries while increasing the level of renewable energy. Similar to renewable infrastructure, blockchain-based projects will incentivize the development of P2P energy grids.Blockchain enables material procurement and provenanceConsumer demand for more ethically sourced products is steadily increasing. Companies have to prove that their product is produced in such a way that protects the environment and public health, and is made ethically. Consumers wary of greenwashing, have had to rely on information provided by companies. Blockchain-based projects are already changing this dynamic.Everledger has created tools to increase consumer and enterprise insight into the provenance of a given object. By combining blockchain, AI and IoT, Everledger digitally streamlines compliance processes and allows companies to demonstrate the true origin of their products.Transparency and traceability will be crucial to fostering consumer trust in food supply chains. Supermarket giant Carrefour and the world’s largest brewer AB InBev partnered with enterprise blockchain developer SettleMint to deliver a digital traceability solution that utilizes dynamic QR codes attached to a product during the packaging process. Green financingGreen financing is the use of loans to support sustainable companies and fund the projects and investments they make. It will be crucial to close the $2.5 trillion annual SDG funding gap, which is estimated to grow bigger. A good example of green financing is the green bond (GB) market. According to the Climate Bonds Initiative, $269.5 billion in GBs were issued in 2020.Unfortunately, GBs are not without problems, such as confirming that sustainability metrics are authentic, or that funds were used to support sustainability. Blockchain can immutably store this data, thus, projects can be verified to satisfy sustainability requirements. Blockchain can help in other ways too, like tokenization.Related: How will blockchain technology help fight climate change? Experts answerOi Yee Choo, chief commercial officer at iSTOX, a Singapore-based digital securities exchange, said in this interview: “Even in markets where the demand for green bonds is high because investors are motivated by ESG considerations, tokenization helps investors diversify their portfolio across different bonds because of smaller subscription sizes.”The blockchain industry is currently far from ideal in terms of environmental sustainability. However, if it maintains its current trajectory, the blockchain industry will not only be an exemplar but an enabler of environmental sustainability.The views, thoughts and opinions expressed here are the author’s alone and do not necessarily reflect or represent the views and opinions of Cointelegraph.Matthew Van Niekerk is a co-founder and the CEO of SettleMint — a low-code platform for enterprise blockchain development — and Databroker — a decentralized marketplace for data.
