The big problem, as I commented further down, is that the volumes of CO2 we need to capture absolutely dwarf the production volumes of essentially any product.

The big problem, as I commented further down, is that the volumes of CO2 we need to capture absolutely dwarf the production volumes of essentially any product.
I just crunched the numbers, and if everything sold on Amazon was made from 100% captured CO2, it would still account for significantly less than 1% of what we need to capture, transport and store.
- the8472 10y agoI don't think "sold on amazon" is a good benchmark when it comes to bulk mass. Construction materials might be a better choice. Concrete production is measured in Gt/a. And of course we also need to reduce carbon emissions, capture is not a singular solution, but it may help during the transition to renewables where we still need gas plants.
- bduerst 10y agoWell concrete already uses lime, which is calcium carbonate (the original carbon sink). Maybe skip the carbon fiber use case all together and figure out a way to effectively produce artificial calcium carbonate.
