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.
Ok… Come on now, I know you’ve been propagandized, and propaganda works, but let’s think this through
Please read what I wrote, not what you think I said.
If you capture CO2 out of smokestacks, what have you done?
It depends on where that carbon came from. If it came from petroleum or coal feedstocks, you’ve slightly reduced emissions. But, the carbon from biofuels originated from the atmosphere. Vegetation captured that CO2 directly from the atmosphere, and incorporated it into the biomass. Burning it converted the biomass into concentrated CO2 and H2O; we’re capturing the concentrated CO2 out of that stream.
Again: this does not replace the need to suspend fossil fuels. But the specific process I described does, indeed, extract CO2 from the biosphere.
If we plow the vegetation under, we are burying the hydrogen and excess oxygen as well as the carbon. Burning it, we release the hydrogen (as water), but still bury the carbon.
