Article Asks How To Insure Carbon Capture and Sequestration
A recent article posted by Evan Lehman on Climatewire (see Wanted: 1,000-year Insurance Policy) asks not how to engineer carbon capture and sequestration (CCS), but how to insure the liability risks of such a long-term enterprise. We all know by now that CCS is the diversion of carbon dioxide from power-plant smokestacks to underground reservoirs, where the greenhouse gas must be stored practically forever. The press has largely been focused on the front-end questions, how do get the gas under the ground? How do we pay for it? But - hey, this is America - it doesn't take long to get to, Who do I sue when the stuff leaks and kills someone or, worse, releases in a day all of the CO2 stored for the last 30 years? Mr. Lehman asks:
Who will stand ready to compensate for the damage if the vast underground vaults supposed to contain the earth-warming gas leak? Will it be the power company that injects the carbon? Will it be the government?
Good question. We can be sure, it will be someone. That's usually where insurance come in. The insurance industry has become more or less adept at underwriting huge risks, like nuclear power plants and space excursions, but the risks associated with these projects are relatively short term. “I can see this being difficult for insurance companies to get their hands around. How do you quantify a policy over a huge amount of time?” said Christopher Walker, director of the Climate Group, a nonprofit that encourages businesses to reduce their greenhouse gas emissions. “There’s nothing, that I’m aware of, that has a history like that."
If the scientists are right and the only way to achieve the 80% reduction in carbon emissions is through CCS, then finding the right balance for long term risk management of CCS will be essential before anyone will agree to undertake the risk.
