The vast majority of places where you can find the kinds of sedimentary rocks that allow carbon dioxide to be stored underground sit in higher risk zones or in areas like the Arctic that are potentially off-limits for practical or political reasons, the study found.

That has big implications for the energy transition, since once carbon dioxide is put into storage, it’s supposed to stay there for as long as possible. Any storage sites we use today can’t be expected to be available for future generations — not just the children and grandchildren of people alive today but “more than ten generations into the future,” the study notes.

The study concludes that nearly 90 percent of that storage capacity is in less-than-desirable locations.
