INEOS plans to transform the Nini oil field in the North Sea into a carbon storage site. The company aims to inject liquefied CO2 into depleted oil reservoirs beneath the seabed.
The energy requirements for storing one ton of co2 are many many times higher than the energy gained from generating one ton of co2 (by oil, gas, coal or biofuel).
So each MWh spent “storing co2” would be ten times more efficient if used to offset oil extraction to get one MWh less out in the first place.
This is wasteful greenwashing. If it wasn’t, we’d have broken physics on the level of making perpetual motion machines.
That’s true but even if we switch entirely over green energy overnight, we’ll still have Steel, still have Bauxite refining for Aluminum, etc, still have to melt and reform glass and aluminum recycled containers, etc, etc.
There are many processes that we really can’t just get rid of, so they will need carbon capture to ensure they’re not hurting the environment.

My brother in Christ, you need massive amounts of electricity to extract aluminum from bauxite. Steel can use electric arc furnaces, as can glass.
Carbon capture and storage is used to re-pressurize under performing oil wells.
Sure, but that’s only relevant once we have 100% clean energy
Developing the technology now is still useful. Waiting until we’re carbon neutral before even thinking about capture would also be mistake.
Lol I love that you think we’ll actually get beyond carbon neutral at some point. You’re far more optimistic than me.
