Hydrogen som energi for fremtiden: SINTEF Hydrogen forskning
Hydrogen fremstilles på to måter. Alt for 200 år siden klarte pionerer å spalte vann med elektrisitet til hydrogen og oksygen. Prosessen passer godt til å lagre uforutsigbar tilgang på sol- og vindkraft, i situasjoner der batterier ikke har nok kapasitet eller når energi skal lagres lenge.
Hvor bærekraftig er hydrogen som drivstoff?
Uansett forsvinner 60-75 prosent av tilført energi i friksjon og varmetap. Virkningsgraden til framdrift i hydrogen er anslått til 35-40 prosent (ved elektrolyse går anslagsvis 40 prosent av primærenergien tapt før hydrogenet er på tanken). Dermed er hydrogen marginalt mer energieffektivt enn bruk av fossile drivstoff.
