Hydrogen at any price?

A specter is running through the media: we must develop "hydrogen technology", then our problems with the storage of volatile "green" solar and wind energy will be solved, while, as is well known, currently the storage of Electricity is only possible in a very insufficient way in high mountain water tanks and lithium batteries. In hydrogen gas we store the excess energy that accumulates when the wind blows too much or the sun shines too bright between the dreaded "dark calms". Electrolytic splitting of normal water then produces oxygen and the desired hydrogen.

Of course, we only want "green" hydrogen so as not to further endanger the world's climate, according to the official line. That is, not "grey" hydrogen produced from natural gas, because that produces a lot of CO2, so it is not better - in fact it is worse - than direct electricity generation, that is, heating natural gas in turbines gas, as is currently done, for example, at the Simmering power station in Vienna. So we want "green" hydrogen, which is produced by splitting water with "green" electricity, that is, electricity coming mainly from wind and sun, and possibly hydroelectric power.
