Hydrogen is one of the most promising energy vectors to assist the low-carbon energy transition of multiple hard-to-decarbonize sectors [1, 2].More specifically, the current paradigm of predominantly fossil-derived energy used in industrial processes must gradually be changed to a paradigm in which multiple renewable and low-carbon energy sources are
A review on metal hydride materials for hydrogen storage
The main advantage of hydrogen storage in metal hydrides for stationary applications are the high volumetric energy density and lower operating pressure compared to gaseous hydrogen storage. In Power-to-Power (P2P) systems the metal hydride tank is coupled to an electrolyser upstream and a fuel cell or H 2 internal combustion engine downstream

Water cycle | Definition, Steps, Diagram, & Facts | Britannica
Evaporation, one of the major processes in the cycle, is the transfer of water from the surface of the Earth to the atmosphere evaporation, water in the liquid state is transferred to the gaseous, or vapor, state.This transfer occurs when some molecules in a water mass have attained sufficient kinetic energy to eject themselves from the water surface.
Energy and the Hydrogen Economy
3. Energy Needs of a Hydrogen Economy Hydrogen is a synthetic energy carrier. It carries energy generated by some other processes. Electrical energy is transferred to hydrogen by electrolysis of water. But high-grade electrical energy is used not only to produce hydrogen, but also to compress, liquefy, transport, transfer or store the medium.

Does the Green Hydrogen Economy Have a Water Problem?
In 1766, Henry Cavendish discovered a lightweight gas which, when burned in air, turned into water. In 1787, Antoine Lavoisier named this new gas "hydrogen", a combination of the roots hydro and genes—quite literally "water-former". Not long after, scientists discovered that by adding electricity to water, hydrogen can be produced by the reverse reaction. Today,
