Reply to comment by burnt-out-b in MIT team makes a case for direct carbon capture from seawater, not air by MotorDrive

0,77MWh is not bad at all. That's like charging an electric car about 7-8 times or less than the monthly power usage of an average household.

A typical older nuclear reactors produce about 800MW. Which is 1000ton/h or 8,8 million a year. 5 reactors would be enough to almost completely offset a country like Sweden.

Almost sounds too good to be true imo.

You still have to store it somewhere.

Storage isn’t that big of an issue at the moment. We have plenty of reservoirs where we have/are pumping oil out

So that's about .385 lbs of CO2 captured per kWh of electricity which is right about where the emissions from electricity generation are in the most efficient states. Using excess daytime solar generation, I can see states with zero emissions targets using this method as an offset for nighttime fossil fuel based generation.

It's about 20g/kWh in Sweden. But the focus should be to phase out fossil fuels first. Once that is done we can start restoring our climate with co2 capture.
