Heat pumps work like this. They pump heat into the ground during hot months, then take some of it back during cold months.

Hear pumps do this, but they pump energy into the ground during hot months to cool the house, then during cold months they pull some of it back.

My bad, the carbon banking would be to clean the atmosphere, being able to burn it is just a side effect.

We could use the excess power to bank carbon, then if we need more power we can burn that same carbon.

Edit: This isn’t to be efficient, it’s to remove carbon from the atmosphere and reverse global warming. I meant that being able to use it as emergency fuel would just be a perk.
