In the process of building a new electricity system and constructing a new energy system, China is facing the challenges of large−scale development and consumption of renewable energy and the green and low−carbon transformation of coal−fired power. Electricity−hydrogen−carbon coupling organically integrates renewable energy, coal−fired power, hydrogen production and carbon utilization, realizing the co−production of electricity and products such as hydrogen, ammonia and alcohol, providing a new path for economically and efficiently solving the two problems, and achieving the transformation of the energy system from high carbon to low−carbon and ultimately zero carbon through the "three−step approach". To achieve the development of electricity−hydrogen−carbon coupling, collaborative efforts are needed in top−level design, technical research and industrial chain construction.
