Life Cycle Environmental and Economic Benefit Assessment of Integrated Energy Station Based on RSOC

In the context of the dual-carbon goal, China's distributed power generation has been vigorously developed, and the power system is facing huge pressure to absorb distributed energy. Reversible solid oxide fuel cells can realize the reversible conversion of electricity and hydrogen, which is a very potential way of clean energy consumption. In order to improve the carrying capacity of the power system to clean energy, this paper proposes a solid oxide fuel cell integrated energy station considering the efficiency decline of each equipment in the energy station, and evaluates the environmental and economic benefits of the energy station. First, combined with the operation characteristics of reversible solid oxide fuel cells and the characteristics of distributed energy output, a comprehensive energy station based on reversible solid oxide fuel cells is constructed. Then, the life-cycle benefit evaluation model of energy station is established from the two dimensions of environment and economy. Finally, typical industrial load and clean energy output data are introduced to evaluate the environmental and economic benefits of the integrated energy station. The results show that the proposed distributed integrated energy station has significant annual carbon emission reduction benefits, and the payback period of investment is about 8 years.
