Direct air capture of CO2 is getting pretty good. Carbon Engineering [1] was in the news recently for demonstrating an efficient scheme at commercial scale. When I looked at the math, their technique would add about 8 cents/kWh to the price of fossil power assuming it was used to capture all the CO2. So if solar is coming in around 2 cents/kWh, you could have 10 cent electricity (competitive in many markets) that also captures as much CO2 as the average fossil unit currently creates. The progress is pretty heartening.
- mulmen 8y agoYeah I think about this in the context of energy density in batteries. Liquid fuel like gasoline has huge benefits for personal transportation just because of the energy density. I wonder what amount of clean energy it would take to make some kind of synthetic/green(?) fuel similar to E85 (E100?). The cost of the fuel could include the carbon capture based on how the fuel is burned. e: looks like you missed a link but I looked up Carbon Engineering and if what they say is true that is really exciting. Especially for airlines and shipping.
