— with each ton of carbon requiring half a kilogram of nitrogen to produce solvent, the amount of nitrogen released into the environment during scaled carbon capture is just going to do more damage to our planet’s ecosystems . Perhaps most nonsensical, however, is the carbon released into the environment during traditional CCS, first to provide the energy to heat the solvent and later during recovery of the oil captured CO2 is pushed back into the ground to help extract.
But enzymatic carbon capture is a very new technology compared to traditional carbon capture methods. It’s not optimized and currently suffers from scalability challenges just like traditional methods. And it’s not the first choice for companies that view CCS as nothing more than a nuisance and are more likely to choose the more established technology.
Financial incentives will certainly go a long way when it comes to motivating companies to implement CCS and other emissions-reducing strategies, but they don’t go too far when efforts are hamstrung at ground level — literally. To truly reach carbon neutral and in time carbon negative status, says Lassen, all the carbon in the oil and gas that we have burned the last century needs to be put back underground, where it must stay for safe storage. And that, unfortunately, is harder than it sounds.
