In a recently published study, scientists demonstrated that two years after injecting CO2 underground at a pilot test site in Iceland, almost all of it has been converted into minerals.

Scientists working at the power plant demonstrated how CO2 emissions pumped into the earth could be chemically changed to a solid within months.

Iceland has seen fast-rising temperatures since the 1970s, and glaciers–a big source of runoff for hydropower–are visibly receding.
