I mentioned beer because the process of capturing CO2 from fermentation and re-injecting it was invented by my family a century ago and apparently was the first of its kind (according to my uncle).

My cousin and a friend of my father are working on accelerating plant and algae growth with CO2-rich atmosphere and water, in urban farms (not greenhouse) and mixed-use aqua-farming respectively. Neither have reached scale yet, but the projects seem promising -- enough that both have considered colocating with industrial CO2 emitters.

I also believe that some people are looking into re-using CO2 to store energy from solar power: focus solar rays and get CO2 to react into longer chain hydrocarbons thanks to catalyst. I’m less familiar with that process.

we all know CO2 and H20 can be recombined to form fuels, its where the fossil fuels originally came from. Where do these bacteria get their energy from? Either from photosynthesis elsewhere, or by photosynthesis themselves. In either case, in order to offset the power plant at the rate is converting fuel to electricity, you need a huge area of plants or solar to recover _all_ CO2. But then you could just remove the fossil fuel burning power plant out of the equation.

It is still perpetuum mobile...
