Compressed hydrogen. Compressed hydrogen is a storage form where hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) is used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology.
NREL's hydrogen production and delivery research and development work focuses on biological water splitting, fermentation, conversion of biomass and wastes, photoelectrochemical water splitting, solar thermal water splitting, renewable electrolysis, hydrogen dispenser hose reliability, and hydrogen production and delivery pathway analysis.
