Moreover, an EHC developed by HyET Hydrogen in the DON QUICHOTE project and the PHAEDRUS project achieved a compression up to 100 MPa and in Japan, an EHC with an active surface area of 10 cm 2 was designed that demonstrated high pressures above 70 MPa under 1.2 A cm −2 through burst testing .
Industrial-scale storage utilizes pressures in the range of 20–30 MPa . High operational pressures for light- and heavy-duty road transport span from 35 to 70 MPa . In some cases, such as hydrogen refueling stations or large production areas, the compression of hydrogen up to 100 MPa may be required.
With the progressive expansion of hydrogen fuel demand, hydrogen pipelines, hydrogen storage cylinders and hydrogen refuelling stations (HRSs) are the primary components of hydrogen energy systems that face high-pressure hydrogen environments.
Hydrogen has a strong effect on the fatigue properties of these two materials. It is critical to develop a kind of hydrogen storage cylinder material that is low-cost, has high strength and is resistant to hydrogen-induced fatigue or a method to resist hydrogen-induced cracking.
The result shows that an electrolyzer unit with 100 MW green energy can produce about 2000 kg/h hydrogen with maximum output pressures of 15 bar and 60 bar using ALK and PEM electrolysis, respectively. This flowrate and pressure are considered as the inlet pressure to the hydrogen compressors.
The Laves phases for hydrogen storage are AB 2 compounds with Ti and Zr on the A site and a combination of 3D transition atoms (V, Cr, Mn and Fe) on the B site. At room temperature and 1 MPa, V–7.4%Zr–7.4%Ti–7.4%Ni alloys (77.78%V), for example, absorb ~2 wt% of hydrogen after the 10th cycle .

Gases, such as natural gas and air, are transported using these types of storage tanks as high pressure is required for transporting hydrogen (35–70 MPa) (Figure 3), whereas natural gas and air only require up to 30 MPa. Conversely, these storage containers do not satisfy requirements in the automobile industry due to high cost and low performance.
The working pressure of the hydrogen storage vessel is increased from 35 MPa to 70 MPa [4], and the liner material is changed from aluminum alloy to plastic [5]. Liao [6], Son [7], Han [8], [9] studied the damage of composite materials in Type III hydrogen storage vessels.

Det er også mulig å lagre hydrogen i form av enkle hydrogenbærende kjemikalier, for eksempel etanol, metan eller ammoniakk. Disse kan i ettertid spaltes for å benytte hydrogenet (som vi så med dampreformering av metan), eller brukes …
Energilagring: Hydrogen kan pakkes ekstremt tæt i nanoporøst stof. Forskere ved Aarhus Universitet har opdaget et porøst materiale, hvor hydrogen kan pakkes dobbelt så tæt som i ren flydende hydrogen. Det skyldes, at hydrogen danner penta-molekylære enheder, som man ikke tidligere har observeret. Hydrogen danner også en ny type binding ...

Onboard compressed gaseous hydrogen (CGH2) storage for hydrogen-powered vehicles is designed for typical operating pressures 35 MPa and 70 MPa. Type III (aluminium liner) and IV (polymer liner) composite tanks are accepted for onboard CGH2 storage due to their light weight and exceptional mechanical strength characteristics.
