Scientists Turn CO2 Into Solid Rock

Scientists in Iceland successfully turned carbon dioxide emissions from a power plant into stone, they reported in Science. The team injected CO2 mixed with water into basalt rock, which formed limestone after two years.

Carbon capture and sequestration (CCS) is a divisive issue in the climate and energy community, but the scientists are confident that solidifying the gas would prevent it from leaking back into the atmosphere, as is the danger with many CCS methods.

"Carbon capture is not the silver bullet, but it can contribute significantly to reducing carbon dioxide emissions," lead author Juerg Matter said of the experiment.

The Biden-Harris transition team identified COVID-19, economic recovery, racial equity and climate change as its top priorities. Rivers are the through-line linking all of them. The fact is, healthy rivers can no longer be separated into the "nice-to-have" column of environmental progress. Rivers and streams provide more than 60 percent of our drinking water — and a clear path toward public health, a strong economy, a more just society and greater resilience to the impacts of the climate crisis.
