Comment on Researchers turn sunlight and CO2 into living biomass
Hirom@beehaw.org 3 weeks agoWhy produce ethanol?
Producing and burning ethanol in internal combustion engines is more polluting, less efficient than using electric vehicles. So this can’t be it.
Producing and burning ethanol for heat is more polluting, less efficient than heat pumps or solar thermal energy. So that’s not it either.
The article mention chemical industry and:
[..] building blocks for products ranging from fertilizers to plastics
This leaves fertilizers and plastics. So this would have to compete with other ways to produce fertilizers, plastic and plastic alternatives (cardboard packaging, wood, glass…)

I didn’t think deeply about this. At least airplanes are still most efficient with kerosine-like fuel. But making plastics would be super important, because it’s such a powerful material.
