"Net energy loss" meaning you have to supply some energy in the form of heat or electricity to make the reaction go, and you don't get it back.
There are things that will react with CO2 and form something that isn't combustible. That reaction may even generate heat that you could hypothetically use for something, but in practice probably not enough of it to be worth extracting.
- cyberax 2y ago> There are things that will react with CO2 and form something that isn't combustible. Sure. There are plenty of such things. For example, elemental magnesium will happily bind carbon dioxide into pretty inert magnesium carbonate. But to _get_ that elemental magnesium, you need to expend energy, because elemental magnesium can't be found in nature. There is only one realistic option: rock weathering. Silicate rocks can react with carbon dioxide to produce calcium carbonate and (eventually) silicon dioxide.
