If I may?

Hydrogen, green hydrogen, can be produced from water, using electricity produced from renewables, like solar amd wind.

My own country is in the process of converting a decomissioned refinery into a hydrogen plant.

It may not solve much in the short term but as an energy reserve, hydrogen can find use directly as a fuel or for running gas turbines to produce electricity in replacement of conventional gas.

It can be made from water and renewables at about 3-4x the energy cost of charging a battery. In train terms, that means you could be charging 3 battery trains instead of 1 hydrogen train. Or you could have 3 battery tenders and have more logistical flexibility in how they are deployed.

To what I know, the hydrogen to be produced is intentended to replace fossil gas in northern europe countries. It's meant to be a stockpileable energy resource.

It's not ideal but we either make middle of the road commitments and actually get something done to move forward or just call it all off an let things fizzle out

Unless someone figures a way to sequester hydrogen into an inert, reversible form you really don't want to be stockpiling hydrogen for obvious reasons.

It's not like we have had disastrous events related to hydrogen.

The objective is to built a trans-iberian pipeline for the liquified hydrogen. So, it will be interesting.
