Wind and solar could meet 85 percent of current US electricity needs

However, the technology is all there. We have it.

Electrolysed hydrogen. There is a lot of development work being done on optimising electrolysis, but it's by no means a lab experiment like carbon sequestration[1] or fusion power. Hydrogen is routinely handled at scale in ammonia production.

If we are to move away from fossil fuels for steel and cement making (and for industrial process heat), we will need to be producing quite a lot of hydrogen. So this just increases demand by a factor of two to five. Best get started on it.

However, you are right. Everyone's been focused on the electricity sector (and to a lesser extent private land transport) up till now. And within that, on production.

I don't think the "not just electricity and cars" message sunk in during COP-26. It will have to soon, though.

1. I distinguish carbon sequestration, technology to permanently lock up carbon at the same scale as our current total fossil fuel consumption, from CCS, carbon capture and storage, which is useful together with hydrogen for feedstocks for industrial chemical manufacturing. CCS is a little further along and easier to do.
