You’ve completely ignored what I said - did you even read it? As far as the economics, not only will it not take a miracle to make “green” hydrogen more economical than fossil hydrogen, but at least one company is building production plants that they say will make it competitive in cost, and then improve it further. The technology is improving quickly, and as the cost of renewables drop, the production costs also drop, as that is the biggest driver of costs.
As far as your comment of being ahead with electricity being stored in a battery, I think your looking at it the wrong way in two (if not more) important ways (and I won’t even get into battery production and recycling issues that don’t get taken into account). First, a battery doesn’t meet all duty cycle needs, which is why for some uses you need hydrogen even if you prefer batteries. The alternative is fossil fuel combustion in an IC engine. That’s why most of see fuels cell electrics as complementary to BEVs, not either/or. Secondly, and maybe more to your point, electricity, like hydrogen, gets produced in many ways. The GREET model, which is generally accepted as the gold standard for calculating GHG comparisons, If I’m remembering correctly, shows both BEVs and FCEVs reducing GHGs as compared to fossil combustion ICEs, no matter the input energy. - Mark Sent from my Fuel Cell powered iPhone > On Aug 13, 2021, at 5:14 AM, Bill Dube via EV <[email protected]> wrote: > > Here is an article published today on "Clean Hydrogen".
