https://en.wikipedia.org/wiki/Hydrogen_economyThe hydrogen economy is using hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the "hard-to-abate" sectors such as cement, steel, long- haul transport etc. In order to phase out fossil fuels and limit climate change, hydrogen can be created from water using renewable sources such as wind and solar, and its combustion only releases water vapor to the atmosphere.

Hidrogen - Wikipedia
https://ro.wikipedia.org/wiki/Hidrogen- Hidrogenul a fost descoperit de către chimistul și fizicianul englez Henry Cavendish în 1766, în urma unui experiment în care studia reacțiile dintre mercur și un acid. La amestecarea celor două substanțe, observa apariția unor mici bule de gaz în amestec. Acest aspect l-a determinat să efectueze o cercetare suplimentară, numind substanța necunoscută „aer inflamabil”. În 1781 …
Hidrogén – Wikipédia
https://hu.wikipedia.org/wiki/HidrogénA hidrogénatomban lévő alapállapotú elektron energiaszintje −13,6 eV, amely nagyjából egy 92 nm hullámhosszúságú ultraibolya fotonnak felel meg. A hidrogén energiaszintjei meglehetősen pontosan kiszámíthatók a Bohr-féle atommodell alapján, amelynek felfogása szerint az elektron a proton körül „kering”, a Föld Nap körüli keringéséhez hasonlóan.
