Hydrogen energy production, storage methods, and applications for power generation

Abstract

Nowadays, the transformation of energy structure has become an important task for society. The advantages of hydrogen energy also meet the criteria of people's choice of energy. This paper introduces hydrogen production, storage methods, and their application for the power generation. In hydrogen production part, POM is the most satisfactory of four methanol to hydrogen methods as this reaction does not require any energy and can be more than 50% efficient. In terms of photolytic water technology, Ti- and Zr-based Photocatalysts, Ta- and Nb-Based Photocatalysts, Ga and Ge-Based Photocatalysts have been applied to increase the reaction rate, in addition, the device has the advantage of a small footprint, ease of operation and high measurement accuracy. In the microbial hydrogen production section, experiments have shown that hydrogen production is highest in a thermally shocked environment, and that genetic modification of the organisms at the molecular level can also increase hydrogen production. For the hydrogen power generation, the PEMFC is by far the most used experimental product for grid-connected power generation. In the future, researchers should focus on solving various existing problems and developing more economical and efficient hydrogen power generation systems to realize the large-scale use of clean energy. Meanwhile, this paper expects to find better solutions to solve existing problems.
