Geothermal for cheap U.S. CO2 capture

Combining carbon-free energy with permanent storage of CO2 creates a more cost-effective self-sustaining loop.

A research team at Ohio State University (OSU) has proposed the combination of carbon capture with geothermal energy in a cheap, novel method that could make capturing carbon dioxide from the air a viable option. Their system recycles some of the captured CO2 to transport geothermal energ...
