Introduction
Blockchain technology has been making waves in various industries, and the renewable energy sector is no exception.
This report by IRENA “Blockchain innovation landscape brief” provides an overview of blockchain technology and its potential applications in the renewable energy sector.
In this blog post, we will summarize the key points of each chapter and provide insights into the benefits and challenges of using blockchain technology in the renewable energy sector.
Description
An overview of blockchain technology and its applicability in the power sector is something that worth to be mention.
Blockchain is a data management tool that can facilitate effective coordination between many actors, with low transaction costs. With the use of “smart contracts,” blockchain technology can automate processes, increase power system flexibility, and reduce transaction costs. It can also accelerate the adoption of other technologies, such as storage and electric vehicles, leading to improved grid management and system operation.
Contribution to power system transformation
Peer-to-peer (P2P) power trading is one of the potential applications of blockchain technology in the renewable energy sector. It allows individuals and businesses to buy and sell renewable energy directly, without the need for intermediaries. Blockchain technology can facilitate P2P power trading by enabling secure and transparent transactions between buyers and sellers. This can increase the efficiency of renewable energy systems and reduce transaction costs. The report provides case studies of P2P power trading platforms, such as the Brooklyn Microgrid and the WePower platform, which demonstrate the potential of blockchain technology in enabling P2P power trading.
Blockchain technology can increase transparency, reduce transaction costs, and improve the efficiency of renewable energy systems. It can also enable peer-to-peer energy trading, allowing individuals and businesses to buy and sell renewable energy directly.
Renewable energy certificates (RECs) are managed through a system of tracking and verification to ensure that the electricity consumed was indeed generated from renewable sources. This is typically done through the use of digital certificates, which represent a certain amount of renewable energy generation.
These certificates can be traded within the European Union and other regions, and can be used to provide proof of renewable energy consumption. Blockchain technology can facilitate the management of RECs by enabling real-time tracking and verification of renewable energy generation data. This can reduce costs by streamlining data verification and automating REC awarding.
Additionally, blockchain technology can prevent double spending and double disclosure of RECs through cryptography and decentralized consensus.
Key factor to enable deployment
One of the main challenges is the lack of standardization and interoperability between different blockchain solutions. Another challenge is the high energy consumption required for proof-of-work technologies, such as Bitcoin and Ethereum.
There are several ways to improve the performance and scalability of blockchain technology. One approach is to use parallel interoperable chains, or “sidechains,” which delegate some computational responsibility to subordinate chains. This approach essentially achieves consensus by parallel processing computations, rather than burdening a single chain.
Another approach is to employ alternative consensus algorithms, such as proof of stake or proof of authority, which can improve the speed and scalability of blockchain technology.
Additionally, certain data can be stored off blockchain or frozen, allowing for enhanced processing times. It is important to note that blockchain technology is still developing, and performance and scalability will continue to improve with time.
Regarding the power consumption, one way to reduce it in blockchain technology is to use alternative consensus algorithms, such as proof of stake or proof of authority. These algorithms require less computational power than proof of work, which is used by Bitcoin and Ethereum.
Additionally, the use of sidechains can delegate some computational responsibility to subordinate chains, reducing the burden on the main chain and thus reducing power consumption. Finally, the report suggests that the use of smart contracts and smart meter technology can help to reduce power consumption by enabling more efficient and effective energy management.
Current state
Blockchain technology is still in the early stages of development in the power sector. However, there are a variety of uses for blockchain being studied, with a focus on optimizing grid management processes and enabling P2P, P2B, and B2B wholesale electricity trading without intermediaries.
Start-ups and consortiums are largely choosing to build their second-layer applications on the Ethereum platform due to its size, ability to host smart contracts, stability, and plans for increased scalability and speed.
Potential applications of blockchain technology in the renewable energy sector include peer-to-peer energy trading, renewable energy certificates, and carbon credits. Blockchain technology can also enable the tracking of renewable energy generation and consumption, providing greater transparency and accountability.
The main activities in the power sector related to blockchain technology revolve around optimizing grid management processes and enabling P2P, P2B, and B2B wholesale electricity trading without intermediaries.
Additionally, the report suggests that blockchain technology can facilitate the management of renewable energy certificates (RECs) by enabling real-time tracking and verification of renewable energy generation data.
It is interesting to note that the European Blockchain Partnership, a declaration signed by 22 European countries on April 10, 2018, is designed to act as a vehicle for cooperation among EU member states to exchange experience and expertise in preparation for the launch of EU-wide blockchain applications across the Digital Single Market.
The aim is to ensure that Europe continues to play a leading role in the development and roll-out of blockchain technologies, including for use in the power sector.
Checklist
The report the provide a list of technical requirements that are necessary for implementing blockchain technology in the power sector. These are:
- Hardware: Smart grid, smart metering, smart phones or computers
- Software: Blockchain support software, smart contracts, and cloud platforms
- Communication protocols: Scale protocols to handle increased transaction loads while maintaining security and increasing speeds, common interoperable standards along with data storage and identity, smart contracts
In addition to these technical requirements, the report suggests that regulatory and supervisory roles are needed to promote safe, efficient, and cost-effective electricity transmission and exchange.
Conclusion
In conclusion, blockchain technology has the potential to revolutionize the renewable energy sector by increasing transparency, reducing transaction costs, and improving the efficiency of renewable energy systems.
However, there are also challenges and limitations to implementing blockchain technology, such as the lack of standardization and high energy consumption.
Despite these challenges, the case studies provided in this report demonstrate the potential of blockchain technology in the renewable energy sector.
