cause global warming, to quote JEP, this is an uncontrolled
experiment on our biosphere that we probably shouldn't be doing
unless and until we know a lot more about what we're doing.
But ...
We are in a Catch 22. Trying to run techological civilization
on exclusively "sunny days when the wind is blowing" energy
is impossible. To the extent the attempt is compelled by force,
the results will be collapse and millions of deaths wherever
it is successfully compelled.
I'm perfectly happy to phase out fossil fuel use as quickly
as possible. Where "quickly" is defined as "Two gigawatts
of nuclear comes on line for every gigawatt of fossil fuel
taken off line. Nuclear comes on line first, *then and only
then* does the fossil go offline."
(Two-for-one for now, because we're behind on electric
generation capacity, and if we're going to have electric cars,
we'll need a lot more electricity to charge them.)
The adamant opposition to nuclear power by the people who
are most gung-ho on the "Global Warming" thing unalterably
convinces me that they do not belive it themselves.
Circa 2000 a group from Princeton came up with a plan to limit the warming to 2.5C which did not involve nuclear, but also did not involve catastrophic economic decline. But even if we accept that this was possible then, it isn't now. Nuclear is a must, at least for a few decades.
I am also pro-hydro, which most greens oppose, though it has to be carefully done (poorly placed reservoirs for dams can emit C02 and CH4 to such a degree that the power is only as clean as non- fracked natural gas. Better than coal, but not good enough).
Fossil fuels will continue to be burnt for a very long time. There is no conceivable way of shutting them down rapidly. We don't currently have a carbon capture system worth anything, but I can't believe it's beyond our abilities. Put Lynn on the job.

But rockets sucked in 1930, televisions sucked in 1940, wind power sucked in 1980, solar sucked in 1990, and so on.
It's an unsolved problem and a hard one. But we really need it, and should take a run at it with a mass of smart people and decent funding.
Which funding would be utterly trivial compared even to the expansion of one highway in Toronto.
If we solve this one people burn fossil fuels to their hearts content, while preserving the real estate value of Florida, and even undo some of the damage we've already done.
So, long shot or no, the payoff is huge.

I think Holcim has some project looking into that for concrete manufacturing, but I'm not sure.

But slowly it seems as if rationality and the laws of physics are overtaking the politicians in the EU at least. Several car manufacturers have communicated that they will continue to sell ICE cars past 2030 or even 2035, since it would be financial suicide for them to go all EV when the politicians told them to.
Another bright spot is the swedish mining company LKAB who were thinking about producing CO2-free steel by 2035, they scrapped the idea too, since it turned out they would need all the current electricity produced by sweden to make the process work, and doubling the power generation and distribution capacity of the country by 2035 would be impossible.
Finally, it also seems as if Northvolt, the eco-bubble battery manufacturer started in Sweden, is close to bankruptcy, due to china outcompeting the. The investors are getting more and more reluctant to throw good money after bad, so I hope it crashes soon.
But this is what happens when politicians try to dictate to the markets what works and what doesn't, so I hope the current generation has learned their lesson, although probably not. ;)
The sad part is that a lot of pension money has been invested in this madness, so future pensions will suffer, but hey, the people voted for it, so they can only blame themselves. ;)
He didn't say "carbon free steel", he said "CO2-free steel".

CO2-free steel production uses green hydrogen to replace carbon in the first part of the process, though of course some carbon must be added to the iron ore (assuming it is not already there) to make steel.

I believe it's called the HYBRIT process.
