It’s more about the how and why.
How: CCS pumps liquefied or pressurized gas into an exhausted oil or saline reservoir. These reservoirs didn’t hold pressurized gas before, so it’s difficult (if not impossible) to prove they won’t leak. In the Decatur case, about 8 kilotons of CO2 and saltwater either found or created a crack in the reservoir, exactly as critics predicted. Locals are worried about groundwater contamination.
Why: CCS is largely unregulated in the US, and the companies interested in it are ones with awful environmental track records – ADM is no exception there. To claim the 45Q tax credit, they only need to store the CO2 for 3 years. Why would they care about preventing leaks if they already got their payout? Doing shoddy work is in their best interest.
Does this event prove that underground CCS is literally impossible? Of course not. But feasibility isn’t a pass/fail test, it’s judged by factors like cost and risk. This event proves the approach isn’t foolproof and the companies aren’t trustworthy. So it’s high time we stop acting like they are.
Ships can register any nation as their flag state, so they often choose flags of convenience based on whoever has the lowest fees or regulations – or more insidiously, whoever has the least ability to hold companies accountable.
This is why so many shipping companies register in Liberia, Panama, and the Marshall Islands. Also Mongolia, which is landlocked.
So unless we want to fill the oceans and ports with ships that have nuclear reactors with no regulation, no safety measures, and no accountability, we’re gonna have to fix the last hundred years of international maritime law.
