Among the many hydrogen-storage materials reported, transition-metal hydrides can reversibly absorb and desorb hydrogen, and have thus attracted much interest from fundamental science to applications. In particular, the Pd-H system is a simple and classical metal-hydrogen system, providing a platform suitable for a thorough understanding of .

Several methods exist for storing . These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of . For many years hydroge.

Chemical storage could offer high storage performance due to the high storage densities. For example, supercritical hydrogen at 30 °C and 500 bar only has a density of 15.0 mol/L while has a hydrogen density of 49.5 mol H2/L methanol and saturated at 30 °C and 7 bar has a density of 42.1 mol H2/L dimethyl ether.

The product of hydrogen combustion in a pure oxygen environment is solely water vapor. However, the high combustion temperatures and present atmospheric nitrogen can result in the breaking of N≡N bonds, forming toxic NOx if no exhaust scrubbing is done. Since water is often considered harmless to the environment, an engine burning it can be considered "zero emissions". In aviation, however, water vapor emitted in the atmosphere contributes to

The newly-launched hydrogen energy development project, led by China Southern Power Grid (CSG), is expected to solve the technical bottleneck of storing hydrogen in solid form under normal temperature conditions. It is based on the principle of chemical reaction between hydrogen and a new-type of alloy material.

Companies internationally are working to produce hydrogen without the carbon output, and in quantities large enough to serve global energy needs to allow us to start relying on it. According to GlobalData, global green hydrogen production capacity reached over 109,000 tonnes per annum (ktpa) in 2022, representing a 44% increase over 2021.

The cleanest way to produce hydrogen is by using sunlight to directly split water into hydrogen and oxygen. Multijunction cell technology developed by the photovoltaic industry is being used for photoelectrochemical (PEC) light harvesting systems that generate sufficient voltage to split water and are stable in a water/electrolyte environment.

is a storage form whereby 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) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology. Car manufacturers including Honda and Nissan have been developing this solution.

“Fundamentally, the aluminum becomes a mechanism for storing hydrogen—and a very effective one,” says Douglas P. Hart, professor of mechanical engineering. “Using aluminum as our source, we can ‘store’ hydrogen at a density that’s 10 times greater than if we just store it as a compressed gas.”
