Applied engineering programs of energy blockchain in US

Abstract Blockchain is regarded as a revolutionary technology, which is widely used in different fields all over world, especially for the application in energy field. With the development of distributed generation, there’s a greater opportunity for distributed generation trading. In the near future, everyone may be able to sell their surplus electricity generated by their rooftop photovoltaic. It can be determined that blockchain can increase the trust between transactors. Blockchain can provide convenience for peer-to-peer (P2P) energy trading. In addition, blockchain can be used in other energy fields such as IOT, shared EV charging pile and etc. Because of the above advantages, many countries in the world are developing energy blockchain and have built some applied engineering programs. Some representative projects in US are introduced in this paper, and advanced technologies adopted in these existing projects are also analyzed. Finally, suggestions for developing energy blockchain technology and conclusions are given.
