here’s a lot of talk about blockchain, from its ability to transform the digital age to its role in Bitcoin mining. And the energy sector is already embracing so-called energy blockchain technology.
The implications of these technological advancements for the energy industry are already being felt with the potential to turn the sector on its head. Let’s explore blockchain in energy and blockchain’s role in the transition to clean energy.
What Is Blockchain Technology?
To understand energy blockchain, we need to understand the core principles of blockchain. This new technology slipped into existence in 2009 with the birth of bitcoin, the pin-up-cryptocurrency for the use of blockchain, followed by many other cryptocurrencies using blockchain technology. But blockchain’s abilities don’t stop there.
Blockchain, in its simplest form, is an enormous database. It’s a digital distributed ledger technology (DLT) that guarantees transparent and secure record-keeping.
All stakeholders on a blockchain can see any approved transactions, for example, when they happened and who triggered them. Furthermore, no one can alter these transactions once approved, and approval only comes once all users agree.
This is called a decentralized peer-to-peer system (P2P), which no single entity controls. Transparency and traceability underpin its existence and make it useful for many online digital transactions.
More traditional centralized systems, like a power plant and power grid, have a few people controlling them as opposed to the millions of users. Centralized systems, for example, allow a power plant boss to shut down operations despite people wanting power.
Unsurprisingly, decentralized systems are proving increasingly popular. Blockchain applications and ecosystems run progressively more and more new initiatives for startups, governments, and businesses. The energy sector is beginning to unleash blockchain solutions to the challenges it faces during the transition to green energy.
Why Should We Adopt Energy Blockchain Technology?
Many energy grids use centralized systems. Colossal power plants control energy supply, sending power over enormous energy grids to customers. However, the energy supply chain is changing thanks to renewable energy sources.
Millions of homeowners, businesses, and governments are embracing microgrid power generation. Solar panels on buildings, small wind turbines, and electric vehicles (EVs) are examples of distributed energy resources (DERs). All of this makes the grid much more decentralized, and could even see people buying energy from their neighbors. But renewable energy isn’t always reliable as it’s intermittent—for example, solar panels can’t always rely on the sun shining and wind turbines can’t always depend on windy days.
Therefore, these DERs can both draw from the power grid and feed into it, helping to balance it when there’s an excess or lack of intermittent renewable energy generation. DERs also make running the power grid complex, with countless stakeholders requiring constant monitoring. That’s where blockchain solutions could step in, accurately recording millions of transactions clearly and openly for all to see.
The world is on an energy transition to net-zero emissions by 2050, and blockchain technology will be part of the puzzle’s solution.
Energy Blockchain Technology: What Are Its Uses?
Blockchain’s great advantage is that stakeholders can choose if the system is 100% publicly viewable or kept to interested stakeholders. The energy sector has the potential to embrace blockchain technology in many ways.

Many use cases are being adopted, providing business models for future integration into quickly becoming smart power grids. The main goals are greater efficiency, lower costs, and transparency, with sustainability and lower carbon emissions as the secondary upside.
Here are a few use cases for how blockchain can help the energy industry.
Blockchain as Part of Energy Trading Platforms
Utilities, energy companies, and even homeowners can now trade energy, paying to use it or being paid or receiving bill credits when generating it. Blockchain allows for peer-to-peer energy trading with real-time prices and immutable energy transaction records for all stakeholders to see, reducing fraud and human error.
Blockchain platforms utilize smart contracts—which execute transactions when pre-agreed conditions are met—to automate the procedure, simplifying the energy market.
WePower has harnessed Estonia’s 100% smart metering energy grid to track the country’s energy consumption and production data on blockchain. It uses Ethereum smart contracts and tokens; Ethereum is a P2P network and one of the world’s largest decentralized blockchain platforms and cryptocurrencies.
Similarly, SunContract in Slovenia uses its blockchain-based energy trading platform to connect emissions-conscious customers with renewable energy suppliers.
Supply Chain Use Cases for Energy Blockchain
Traceability is critical for energy blockchain. For example, a customer could choose a renewable energy supplier and use energy blockchain technology to verify their power source. This can also cover carbon emission credits or renewable energy certificates.
Australian startup Power Ledger connects local green energy producers on microgrids so they can trade on a P2P energy trading system. Everyone involved in the blockchain can check if the energy provided comes from its stated source.
Blockchain could eliminate intermediaries like power brokers by allowing more direct sales and energy purchases. This could reduce energy prices.
Smart Grid Management and Energy Efficiency
Many blockchain processes are automatic, improving the energy ecosystem’s efficiency and sustainability. Incorporating microgrid energy producers helps reduce transmission loss from centralized power plants, monitor renewable energy sources, or switch to storing excess energy in utility-scale or electric vehicle batteries.
EV batteries can smooth out bumps in energy supply and demand, either drawing down excess energy or feeding in during shortages. Blockchain technology can track all these transactions.
Furthermore, the open nature of blockchain solutions means stakeholders can check electricity market trends in real-time. Technological advances will also have a significant influence on blockchain adoption. For example, AI, big data, automation, smart metering, and the Internet of Things (IoT) are all part of expanding a more connected power grid, the Internet of Energy.
Blockchain can underpin the enormous number of transactions for everyone involved. It can help with asset management, leaks, power trends, etc.
Blockchain and Energy Industry Regulatory Compliance
Regulators using blockchain technology could check colossal data sets about power grids, utilities, electricity providers, and customers more easily using blockchain. Data would be clean and tamper-proof, increasing confidence in the energy supply chain.
Energy giant Shell is looking at how decentralized blockchain technologies can track regulated products like carbon capture credits. This immutable record of carbon credits could help prevent “greenwashing” by industry and restore public faith in apparently eco-friendly schemes.
Blockchain can track big data, helping power plants and large energy generators identify leakages and improve productivity.
What Are Positive Examples of Energy Blockchain?
Europe has already made strides in blockchain adoption. In Spain, electricity retailer Iberdrola has championed a pilot project that authenticates the clean energy it provides customers. Companies use blockchain technology to verify that their electricity comes from nearby wind farms, with the ability to trace the power to its source.

Acciona Energy was the first utility to track renewable energy sources on blockchain over its Spain and Portugal electricity market.
France-based EDF launched a blockchain-based peer-to-peer energy trading system in Brixton, London. Locals can buy excess renewable energy produced by neighbors’ solar panels, with all transactions recorded on a blockchain. EDF’s massive blockchain technology setup is also converting people’s excess energy production into tokens that can be traded on its blockchain and recording bank transactions.
Blockchain is not only in the energy sector. In 2016, Estonia installed a blockchain solution to protect all its 1.3 million residents’ healthcare records.
What Challenges Face Blockchain in the Energy Sector?
The possibilities for blockchain are mirrored by the challenges faced in the energy sector.
For example, energy trading requires a smart grid and smart metering. Not all power grids are smart-ready, reducing blockchain’s reach until every aspect is digitized. Also, blockchain doesn’t guarantee a safe and balanced power grid—it can only monitor the transactions.
The market may resist the energy transition from centralized to decentralized. Big players in the energy market may resist the move to a new system while learning how to protect their market share. The idea of 100% transparency is appealing to some, but not all, energy industry players.
Blockchain’s Achilles’ heel is speed, scalability, and security, which, if solved, would foster trust and boost adoption. There pervades a cautiousness over blockchain and its association with cryptocurrencies: governments, utilities, and big businesses must learn how to regulate these more agile decentralized systems.
There have been many high-profile cryptocurrency scams and hacks. While not related directly to energy blockchain, they shine a good light on the overall technology. Blockchain is also not 100% hack-proof, albeit the decentralized nature of its ecosystem makes it very hard to hack.
Public perception is vital too. While not directly associated with blockchain, stories like Texas grid operator ERCOT paying over $31 million in energy credits to Bitcoin miners don’t help. Summer heatwaves led ERCOT to ask heavy energy users like Bitcoin mining company Riot to ease consumption in return for credits worth more than the bitcoin it mined.
Why Is Blockchain Important for Renewable Energy’s Future?
Renewable energy’s future is one of many faces. There will be utility-scale solar and wind energy farms, hydropower plants, thermal energy, and battery storage systems. These will work alongside millions of microgrids in people’s homes and businesses.
Renewable energy may be just that: renewable. But it’s all intermittent. Cloudy, windless days require power plants or other energy sources like batteries to pick up the slack in demand.
No human can safely monitor millions of stakeholders operating within a decentralized system, all buying, selling, and producing energy in real-time. Blockchain offers a transparent system with traceability at its heart. Buyers and sellers can check if pre-agreed terms have been met, and the value of renewable energy—excess of shortage—will be seen within the market.
What Is the Future of Energy Blockchain?
Blockchain, or energy blockchain, is already making headway into the energy market. The strength of blockchain technology is its democratic approach to decentralized systems, allowing players big and small to operate safely within the energy market. Small-scale and utility-scale pilot projects are underway, ranging from energy trading to tracing renewable energy sources.
The rapid digitalization of our energy system, with smart meters, IoT, and artificial intelligence, all form part of the future, leaving a gap in the market. Someone or something needs to monitor all this digital activity transparently in real-time to ensure fair play.
However, blockchain remains a nascent industry facing scalability challenges and, ironically, trust. The test for blockchain is to meet those issues head-on, alongside finding out if the energy sector is ready for 100% accountability for its actions.
Blockchain advocates hope that its blockchain technology will plug the gap. Indeed, market forecasts suggest investment in blockchain will rise from $11 billion in 2022 to nearly $470 billion by the end of the decade. Energy blockchain covering the enormous energy market will surely follow the trend because it has much to gain from traceability and trust.
