Reply to comment by mydoglikesbroccoli in scientists Find Way to Suck Carbon Out of the Air and Turn It into Baking Soda... by Minute_Drive5038

The sooner people accept that carbon sequestration will require enough energy to reduce CO2 back to hydrocarbons, the sooner we will accept that the elimination fossil fuels is inevitable.

Which according to thermo, is about as much as we got out of burning them, assuming 100% efficiency. I think there's a little bit of wiggle room if you can find a low energy compound to turn it into, but it's still going to be a lot. And it can't be a neutralized acid like formate or bicarbonate. Maybe add H2 and do some electrochem to make oxalic acid? It's a powder, which would be a bonus for disposal.
