"Ovaj prirodni resurs mogao bi zaobići visoke troškove i zagađenje povezano s trenutnom proizvodnjom vodika. No, ključno je pronaći dovoljno velike količine."
A rovanje i bušenje po planinčugama prekrivenim šumama, strojevima pogonjenim motorima na unutarnje izgaranje - ne bi bilo povezano s visokim troškovima i zagađenjem?
Čini se da je Sunce i opet postalo preskupo. Kad teba energija za data centre koji uglavnom proizvode stupidne iluzije, koju fosilni ne dospijevaju proizvesti, onda se solarne elektrane mogu i u orbiti graditi, ali kad treba udariti konkurenciju fosilnima tu na Zemlji, onda je to skuuupooo, čak je isplativije bušiti duboko ispod stjenovitih planinčuga i zaleđenog morskog dna umjesto proizvoditi vodik (ili direktno struju) pomoću energenata koji doslovno padaju s neba.
Naravno, i bušenje zbog geotermalne energije je opet skuuupoooo.
Još je jedna zanimljivost da kada se pokrene priča o gorivnim člancima/ćelijama, onda čistog vodika nigdje na planetu nema niti za lijek.
A nije baš da živimo u 19. stoljeću:
With the new factory, Siemens Energy is making electrolyzers a mass product, laying the foundation for the ramp-up of the hydrogen economy. For hydrogen to become the game changer for a climate-neutral future, it must be available in large quantities and at competitive prices. This requires serial production of cost-effective and scalable electrolyzers. With an annual production capacity of one gigawatt, Siemens Energy and Air Liquide expect a ramp-up to at least three gigawatts by 2025 with potential for more. In comparison: with installed electrolysis capacity of three gigawatt, an average of 300,000 metric tons of green hydrogen can be produced per year when operated with renewable energies. Using this green hydrogen to replace fossil fuels would avoid the CO2 emissions of a major German city with around 260,000 inhabitants like Aachen.

A revolutionary green hydrogen production method using seawater has been developed by Torvex Energy Ltd with support from the Materials Processing Institute and SGS.
...
Currently most of the green hydrogen comes from electrolysis of purified water which requires significant energy use. The use of natural seawater enables hydrogen production without the need for costly and energy intensive purification.
Additionally green electricity, solar or wind, could be used to power the reactor, thus making this a fully green method of hydrogen production.
Rates of energy required for hydrogen production from the prototype are comparable to some current large scale commercial production. Scale up from prototype to commercial scale can make this process more efficient.

Nove tehnologije su zrele, ali čini se da nedostaje političke volje da se one masovnije uvedu.
