For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H 2: it boils around 20.268 K (−252.882 °C or −423.188 °F).

Hydrogen energy storage has the advantages of cross-seasonal, crossregional, and large-scale storage, as well as quick response capabilities, which is applicable to all links of

Hydrogen fuel cells are currently significantly ahead of chemical power sources in terms of specific energy intensity: 524 Wh/kg for vessels with hydrogen at a pressure of 35 MPa. Among the existing technologies, a lithium-ion battery is the closest in terms of this indicator, but the capacitance of lithium-ion battery is several times less than

Fig. 1 presents a general scheme for the production of green-H 2 in a power-to-hydrogen (P2X/P2G) setting: a renewable energy source is employed to power a water electrolyzer and a H 2 compression system. This green-H 2 can be employed as a fuel, in fuel cell electric vehicles or replacement for natural gas in heating, or as a

Hydrogen is stored and can be re-electrified in fuel cells with efficiencies up to 50 percent. A fuel cell generated electricity through an electrochemical reaction instead of a combustion. See the diagram below for a depiction of a hydrogen fuel cell. Hydrogen storage is unique. Hydrogen can be tanked like propane or turned into a powder.

To meet ambitious targets for greenhouse gas emissions reduction in the 2035-2050 timeframe, hydrogen has been identified as a clean "green" fuel of interest. In comparison to fossil fuel use the burning of hydrogen results in zero CO 2 emissions and it can be obtained from renewable energy sources.
