energilagring
Kjemisk energilagring gjøres hovedsakelig ved elektrokjemiske prosesser, for eksempel ved opplading av akkumulatorer. Kjemisk energilagring kan også oppnås ved å omforme elektrisitet til et energirikt brensel i form av gass som hydrogen og metan. Dette gjøres ved hjelp av elektrolyse som reduserer vann til oksygen og hydrogen.

hydrogenlagring
Hydrogenlagring er lagring av hydrogen på en måte som gjør at den lett kan omsettes og tas i bruk som energibærer. Under alminnelig trykk og temperatur opptrer hydrogen i form av gass. Gass er lite egnet for transport og lagring, og derfor blir mesteparten av hydrogenet som produseres i dag brukt på stedet, for eksempel til produksjon av ammoniakk.

Lagring og bruk av hydrogen
Det er også mulig å lagre hydrogen i form av enkle hydrogenbærende kjemikalier, for eksempel etanol, metan eller ammoniakk.

Bruker man denne måten å lagre hydrogen på, kan man oppnå enda større tetthet av hydrogen.
