Abstract
The Energy Internet has become a hot topic for the integration of sustainable energies. However, as a result, there are numerous sustainable energy forms and participants, the system is extremely complex, and some key issues are difficult to overcome, such as the control and management of distributed sustainable energy forms. On the other hand, blockchain technology consists of distributed data storage, peer-to-peer transmission, a consensus mechanism, encryption algorithms, and smart contracts. Applying the technical advantages of the blockchain to the Energy Internet can solve many of the problems that hinder its development. The purpose of this paper is to review the development of blockchain and the Energy Internet, and provide some references for the possible applications of blockchain technology to the Energy Internet. Firstly, the definition and characteristics of blockchain and the Energy Internet are introduced in detail. Secondly, the compatibility of the two is analyzed. Then, several application scenarios of blockchain in the Energy Internet are put forward. Finally, the challenges that still exist when applying the current blockchain technology to the Energy Internet are analyzed.
Highlights
With the rapid development of sustainable energy technologies and network technologies, the Energy Internet represented by “New Energy + Internet” has become the new frontier of technological innovation in the international energy academia and industry
[15] The data structure of the blockchain is mainly composed of a block header and a block body [16]: the block header mainly contains the hash value of the previous block, which is used to connect the previous block to ensure the integrity of the block chain; the block body contains the main information of the block
Rifkin [43] stated in the book entitled “The Third Industrial Revolution” that with the depletion of traditional fuels and the gradual deterioration of the global environment, humanity will enter into an Energy Internet system that combines new energy technologies and new information technologies
Summary
With the rapid development of sustainable energy technologies and network technologies, the Energy Internet represented by “New Energy + Internet” has become the new frontier of technological innovation in the international energy academia and industry. The article proposes that what is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party He created the first block of the blockchain in January 2009, which is known as the “Genesis Block”. The key technologies in blockchain such as consensus mechanisms, encryption algorithms, smart contracts, and distributed data storage can be used to solve some of the difficult problems in the construction of the Energy Internet. The energy and information between systems are highly interconnected, and the transparency and security of data must be concerned with the basis of intelligent transactions [8] According to this principle, if the Energy Internet uses a traditional solution to establish a central institution as the trusted center, all of the transactions would be transported through the central institution. Part 5 summarizes the research and several application scenarios of blockchain technology in the energy field; the challenges in the application of blockchain technology in the Energy Internet are presented in part 6
