The renewable energy hydrogen car: the future?

[sicetaitsimple]

By the way, what is your answer for?

It should be noted that geothermal energy produces about 0,25% of electricity in Japan, and solar 7,4%, ie 30 times more. Why?

And? It is constantly increasing. As for bio methane, as for wind power, as for tidal power. As with everything related to renewable energies. By the way, what is your answer for?

Iceland is much more volcanic than Japan, has 100 times fewer inhabitants per km ^ 2, and does "only" 25% of its electricity by geothermal energy (hydraulics by doing 3/4). So geothermal energy will remain peanuts in Japan. Feeding 150 million inhabitants is not like feeding 300.

Today, almost 100% of the electricity and heating consumed by Icelanders comes from renewable energies. Nine out of ten homes are heated directly by thermal energy. Iceland's energy potential now far exceeds the needs of its people.

(Not to mention agricultural production)
I don't see why they would do without hydraulics, which are much easier to produce than geothermal energy. Once again your "will represent peanuts in Japan" is completely free. More clairvoyance, at what term: 10, 20, 50, 100 years, 1000?

With 100 times less population compared to the area ...

Energy. Natural hydrogen, an El Dorado to explore

Except to capture this famous "native" hydrogen. Which indeed seems to be produced continuously by the earth's crust. "This is done through two processes: diagenesis which is a reaction between water and certain rocks containing metals, and radiolysis, by which the natural radioactivity of rocks breaks water molecules."

It is especially the first cause which seems to give rise to the highest productions. "But the resources are still poorly known, despite the warning that was issued in their time by Russian researchers as well as by the French Petroleum Institute and the National Institute of Sciences of the Universe," deplores Isabelle Moretti.

Very few sites are operated around the world. "We know of at least two, in Mali and in Kansas. But the presence of native hydrogen is established in Iceland, where it would be easy to exploit, as well as on the rifts of East Africa, or in the Moscow region, Brazil in Minas Gerais, the Philippines, New Caledonia and even in the Pyrenees. "

Isabelle Moretti, who for her part commissioned doctoral students to better understand the resources identified in Djibouti, believes that "we must now adapt the research methods - seismic or aerial - then proceed to drilling to find out whether the deposits are viable" .

The scientist is convinced of this: "Today we are at the same stage with regard to hydrogen as when we made town gas from coal. And then we discovered that it there were deposits ".

Annual electricity generation in fiscal 2017 was approximately 2 GWh (Yasukawa et al., 409).

That is to say about 0,25% of the total production of the order of 1000TWh.

For those who write "Huh, Houston we have a problem" a little high, solar PV is 7,4% in 2019.

Note that Iceland's production (more volcanic) is around 6000 GWh, which is 2,5 times more than Japan, so the Japanese are not that bad.

Except that for Iceland it is 30% of its electricity while for Japan it is only 0,25%, but "we don't care" eh.

And Désertec? (I mean thermodynamic solar), still no interest from you ...? I see...
