Defossilization

That was a new term for me: defossilization. We will still very much need carbon-based compounds (even after we transition to 100 percent sustainable energy) for manfacturing of plastics, detergents, medicines, and more.

Okay, so we still have plenty of oil around...so why not use the oil for that? We should have plenty 'excess' capacity in the oil fields! Plan is a CO2-to-methanol process powered by solar energy and then the methanol is converted to olefines (e.g. ethylene & propylene) which are petrochemicals that can be used to manufacture plastics and more.
