The problem is there's no practical green hydrogen today. It comes from basically boiling/splitting water or extracted from natural gas or other fossil fuels. And the energy you could use to make the hydrogen could more efficiently just be used as electricity and stored in an ev battery. When/if we figure out how to efficiently separate hydrogen from water we can come back to it.

That's mighty big of you to step up and make these collective decisions for us all regarding hydrogen. It's a pity break away billionaires with heavy industry backgrounds haven't heeded your sage advice and are pressing ahead regardless. * https://www.ttnews.com/articles/phoenix-hub-plug-power https://www.ttnews.com/articles/phoenix-hub-plug-power * https://norwegianhydrogen.com/ https://norwegianhydrogen.com/ * https://www.incitecpivot.com.au/sustainability/projects/green-ammonia-at-gibson-island https://www.incitecpivot.com.au/sustainability/projects/gree...

  I'm not making decisions for society. I'm reporting the current reality. Consider looking at the disastrous situation in California for people with hydrogen powered cars. Typical discussion is at https://www.reddit.com/r/Mirai/comments/17md2gr/called_toyota_about_a_buyback/ https://www.reddit.com/r/Mirai/comments/17md2gr/called_toyot... I'm all in favor of alternatives for gasoline. We just need some that don't perpetuate carbon fuel use. The mirai folks end up paying way more for hydrogen than gas, way way more in that subreddit, run into unavailability of fuel, the stations break and aren't repaired. I was quite surprised when I came upon the discussions there. When or if we can create h fuel without using lots of fossil fuel and energy it would be great. Today it's primarily companies and govts perpetuating their industrial bases in Japan that seem to be pushing hydrogen.

    I've just linked to the current reality - large operators (eg: people that meet the global steel demand by delivering ~ one billion tonne of iron ore per year via operating large fleets of diggers, trucks, trains, etc 24/7/365) have already built and are building out more green hydrogen infrastructure and investing serious money into better electrolysers, etc. With an excess of sunlight hydrogen can be used to generate electricity at night to recharge mobile equipment batteries and cable powered semi mobile equipment, with conversion of hydrogen to ammonia it can be bulk shipped to large scale generation plants elsewhere. > Consider looking at the disastrous situation in California for people with hydrogen powered cars. Not especially relevant here to the current reality of large scale green hydrogen generation for direct industrial application to reduce greenhouse gas emmissions though, is it? Californians struggling with small cars doesn't negate what else is happening in our current reality.

      ok, glad it's working somewhere. In the case of hydro cars in the us, toyota is agreeing to buy them back, giving free use of gas cars, etc.
