Don't even think about carbon capture. Affording it any thought as a production process in the current world is "conservation of energy forbids it" level of impossible. Technology doesn't make it better either, it's just not feasible with the current energy output of the human race, not with (the very impressive) biogas pyrolysis nor with literal "air plastic".
Existing processes are the best use of hydrogen, and for those I'm fine with anything. It just makes little sense for energy applications.
- legulere 4y agoThe problem with carbon capture usually is extracting CO2 from the air and storing it without being emitted again. Methane pyrolysis uses hardly more energy than steam reforming and leaves solid carbon as a side product. You don't need to concentrate carbon from the atmosphere, that was already done, solid carbon can be stored way more easily than the gas CO2. It has a very limited scale though, as you want to only use waste products for biogas production.
