Hydrogen has the most potential as an energy resource alternative to fossil fuels, with numerous applications across sectors. It is clean and is present in a great amount in nature. However, due to the challenges in handling hydrogen and hydrogen embrittlement, its storage remains a concern, which is why high strength steels are rarely employed for such applications. To improve these hydrogen storage systems and address issues such as low energy efficiency, weight, long refueling periods, durability, hydrogen embrittlement, and costs, better hydrogen impermeable materials must be created. There are many material-based storage methods and coatings to reduce embrittlement and other problems faced by conventional storage methods like compression and liquefaction, but more investigation on high strength steels is necessary as they could be more efficient hydrogen storage materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
