Yeah I'm not a domain expert on decarbonization or anything, but from what I've seen on the industrial manufacturing side of things in the US, electricity prices would have to be
consistently very low for the cost of re-outfitting existing natural gas heating systems with electrical ones to make sense without fairly punitive carbon taxes, and even if you pass carbon taxes in first world countries to make it "worth it" to retrofit with electric heating, most of the domestic manufacturing will just go belly up without tariffs--good luck getting developing economies to enforce the environmental standards most of us would like to see on their own, and good luck getting the ruling body politik to think tariffs are a good idea. I ran the number on our facility and moving from natural gas boiler heating to electric would have been iirc something like 8-12x more expensive, even before buying the very expensive heaters, and I'm fairly certain that for higher temp operation(our steam system was low pressure) it would be even more expensive.
There are a couple other stand out problems I see with getting the industrial/manufacturing sector off fossil fuels. First, I don't think that we have the grid infrastructure to replace natural gas with electrification at the same time we do cars[1][2]. From what I understand its something of a problem already for electric car charging, and industrial use of gas for heat (and saying nothing of trying to replace the petrochemical industry, interesting read on all-electric ammonia production [4]) is pretty staggering as well; electric transmission is some substantial multiple less efficient then direct heating with Gas. I think this is kind of the opposite of electric cars which tend to be more efficient than ICE, but again I'm not an expert and am not at all sure that is true of cars, just my impression which seems reasonable intuitively, as turning fuel directly into heat has essentially 100% efficiency while turning fuel into motion can only be some fraction.
Second, super cheap electricity is extremely fungible, so it becomes a prime candidate for Jevon's Paradox[3]. I feel that there would have to be some "unfair" power rates for heating for electricity to supplant natural gas unless we implemented massive carbon taxes, in which case return to my first point about off-shoring.
I can see how it would theoretically make sense to put industry right next to large power generation sources, like dams, solar array/ battery installations, or nuclear power plants(lol), but a lot of these operations aren't exactly trivial to move, and our current climate of Environmental regulation makes moving these sorts of things that much more difficult. Also manufacturing requires a not insignificant amount of logistics/shipping so transplanting them to power generation sites has its own set of drawbacks.
All in all, I try to be a techno-optimist, but seriously worry that humanity's ad-hoc system of organization (that's rife with corruption) will be our downfall in this global climate crisis we've created. So far I can't see a way out of this without a breakthrough in power generation and a breakthrough in carbon capture or some other unforseen-by-me break through. Really I just don't see our current tech stack as being capable of getting us out of this mess. So here's hoping that high-temp super conductors bare fusion fruit, and this gallium catalyzed CO2 splitting is the real deal.
