Co-configuration of Hydrogen Equipment for Multienergy System Considering Time Coupling of Carbon Dioxide and Hydrogen

Abstract

The cooperation between the power to gas and carbon capture and storage technology can increase the utilization rate of wind power and reduce the carbon emission of the integrated energy system. However, there is a problem of time scale mismatch between electric hydrogen production and carbon dioxide capture, which makes it difficult for carbon dioxide to be used immediately, and there is a risk of storage leakage. In this paper, hydrogen storage and hydrogen fuel cells are used to decouple carbon dioxide from hydrogen in time scale to realize immediate utilization of carbon dioxide, and a cooperative configuration model of hydrogen devices is established. The simulation results that the rational allocation of hydrogen equipment can effectively increase the utilization rate of wind power, and reduce the carbon emission and the total cost of the integrated energy system.
