90% of hydrogen worldwide is made using carbon sources. First de-carbonate that before talking about "clean energy". Most of the trucks nowadays can be replaced with trains. Let's focus on that first. This it not an engineering issue, it's a political and organizational issue.

thank you. it would be nice if there was more recognition of the whole energy chain rather than the pretense that lithium, electricity etc just spring fully-formed from the ether

> 90% of hydrogen worldwide is made using carbon sources. Because 90% of worldwide energy anything is currently non-renewable: https://en.wikipedia.org/wiki/World_energy_consumption https://en.wikipedia.org/wiki/World_energy_consumption Power to gas is actually a technology employed productively to convert excess renewable energy into hydrogen etc.: https://en.wikipedia.org/wiki/Power-to-gas https://en.wikipedia.org/wiki/Power-to-gas I fully agree with your goal, though I do think this isn't a first this than that situation.

> Most of the trucks nowadays can be replaced with trains. Let's focus on that first. Yes and no. Trains do not work well for distribution centers like walmart, krogers, target, etc... The last 1-100 miles will need trucks. Long haul, yes, trains _can_ be used. But there are situations where that is not a feasible solution.

  Right, but long-haul is where batteries don't work. If we can get rail to every regional distribution centre (or rather, build regional distribution centres at rail yards) and then use batteries for the last hundred km, that's a win.

So Volvo should give it all up and go into US political lobbying? Or learn how to build a train? I don't agree. Global warming is an issue that should be approached with a multi-prong attack. And, if there is a future where hydrogen is clean and abundant, there's no point waiting for it to start working on making it useful.
