Abstract: Blockchain，featuring a decentralization，encryption，non-tampering，transparency，fairness and openness
breakthrough technology，provides an fundamental solution for global energy transformation and upgrading. Based on the
definition of energy blockchain，description of its main characteristics，technical framework and potential，and typical
engineering projects applied blockchain technology in microgrid，oil-gas field，renewable energy，and shared charging
stations（piles）for electric vehicles，Industrial Internet of Things and smart grid are analyzed. These cases provide
recommendations for the sustainable development of energy blockchain in China.

Key words: energy blockchain, technical framework, development potential, global project, engineering projects, renewable
energy, charging stations
