Abstract

The invention relates to a hydrogen-electricity conversion energy system, which comprises: a hydrogen storage system used for storing hydrogen in a solid state; a reversible fuel cell system connectedbetween a power grid and the hydrogen storage system, wherein the reversible fuel cell system comprises a hydrogen production module and a power generation module, the hydrogen production module is used for converting electric energy provided by the power grid into hydrogen energy to be provided for the hydrogen storage system, and the power generation module is used for converting hydrogen energy provided by the hydrogen storage system into electric energy to be provided for the power grid; and a hydrogenation system connected with the hydrogen storage system and used for hydrogenating hydrogen consumption equipment by utilizing hydrogen energy provided by the hydrogen storage system. According to the hydrogen-electricity conversion energy system, hydrogen is stored in a solid state, sothat safe storage of hydrogen energy is realized; a reversible fuel cell system realizes conversion between hydrogen and electricity, replaces hydrogen transportation with power grid power transmission, and solves the problem of difficulty in hydrogen transportation in the hydrogen energy industry; and the reversible fuel cell system can also utilize hydrogen in the hydrogen storage system to generate electricity and supply energy to the power grid, so that energy storage and peak regulation of the power grid side are realized.

Description

technical field [0001] The invention relates to the field of hydrogen energy utilization, in particular to a hydrogen-to-electricity conversion energy system. Background technique [0002] Hydrogen energy is the cleanest energy among the currently known energy sources. It can truly achieve zero emissions and no pollution, and has a good application prospect. The hydrogen energy industry includes hydrogen production, storage and transportation, hydrogen refueling and hydrogen utilization. Among them, hydrogen energy storage and transportation technology is related to the storage safety, transportation and distribution of hydrogen energy, and has an important impact on the popularization of hydrogen energy. [0003] However, the most mature traditional hydrogen storage technology is high-pressure gaseous hydrogen storage. This hydrogen storage technology has the problems of high storage pressure and high risk factor, which brings great pressure to the safety management of hydr...
