Is it Hydrogen Energy the Future? Current Development of Hydrogen Purification and Storage Technologies: A Review

Hydrogen energy is considered to be one of the most environmentally friendly and potential green energy options due to its characteristics of producing only water and no carbon emissions after combustion. Low‐carbon and zero‐carbon can be achieved using hydrogen energy. Therefore, in the future, it will be the mainstream because it can achieve the goal of net‐zero carbon emissions. Hydrogen can be obtained using hydrogen purification technologies, which are mainly divided into pressure swing adsorption technology, condensation separation technology, metal palladium membrane separation technology, and metal hydride separation technology. Hydrogen storage technologies are mainly divided into compressed hydrogen storage, liquefied hydrogen storage, cryo‐compressed hydrogen storage, metal hydrides hydrogen storage, liquid organic hydrogen carriers, and underground hydrogen storage. Additionally, with the increasing focus on renewable energy, solid‐state hydrogen storage holds great promise for future applications in various sectors.
