Hydrogen-to-electricity conversion energy system

Abstract

The invention relates to a hydrogen-electricity conversion energy system. The hydrogen-to-electricity conversion energy system includes: a hydrogen storage system for solid-state hydrogen storage; a reversible fuel cell system, which is connected between the power grid and the hydrogen storage system. The reversible fuel cell system includes a hydrogen production module and a power generation module, and the hydrogen production module is used to The electric energy provided by the power grid is converted into hydrogen energy to be supplied to the hydrogen storage system, and the power generation module is used to convert the hydrogen energy provided by the hydrogen storage system into electric energy to be supplied to the power grid; It is used to refuel hydrogen-using equipment by utilizing the hydrogen energy provided by the hydrogen storage system. The hydrogen-to-electricity conversion energy system in the present invention realizes the safe storage of hydrogen energy through solid-state hydrogen storage; the reversible fuel cell system realizes the conversion between hydrogen and electricity, and uses grid power transmission instead of hydrogen transportation, which solves the problem in the hydrogen energy industry. The problem of hydrogen transport is difficult. At the same time, the reversible fuel cell system can also use the hydrogen in the hydrogen storage system to generate electricity to supply energy to the grid, realizing peak regulation of energy storage on the grid side.

Description

technical field

[0001] The invention relates to the field of hydrogen energy utilization, in particular to a hydrogen-electricity conversion energy system. Background technique

[0002] Hydrogen energy is the cleanest energy among the known energy sources. It can truly achieve zero emission and no pollution, and has a good application prospect. The hydrogen energy industry includes hydrogen production, storage and transportation, hydrogen refueling, and hydrogen use.
