E-fuels are a big deal, particularly for aviation. Non-electricity emissions are also something to watch. Hydrogen as a reducing agent seems like it can work very well as long as we do phase out fossil fuels like promised, so that solves steel production and similar. Calcination CO2 from concrete kilns is a very sticky wicket apparently, since they’re extremely hot, heavy, and also need to rotate, which is challenging to combine with a good seal.
Cheap grid storage is a trillion-dollar question, but I suspect even if new technology doesn’t materialise, pumped air with some losses can do the trick, again subject to proper phase-out of dirty power sources.
Yes, code please! This sounds amazing.
