Review on Key Technologies of Hydrogen Storage Equipment
Hydrogen storage is one of the five key links in the entire hydrogen energy industry chain.Some key technologies of hydrogen storage equipment for hydrogen refueling stations are reviewed in this paper.High-pressure gaseous hydrogen storage technology is mature and cost-effective,which have found wide application,but its low volume hydrogen storage density and safety issues are the bottlenecks currently faced in the technological development.Solid state hydrogen storage provides higher volumetric hydrogen storage density and hydrogen release purity,but there are technical challenges such as high cost and poor cycling performance.Although cryogenic storage technology has the highest hydrogen storage density,the liquefaction process requires high energy consumption and equipment costs.Organic liquid hydrogen storage has prominent advantages in long-distance transportation and storage,but the high technical complexity and cost issues have not yet been solved.This paper elaborates the advantages and disadvantages of these technologies,explores their future applications,and points out future research directions,aiming to promote the development of more effective hydrogen storage solutions and help hydrogen energy develop into a key component of the future energy system.
