Geothermal power plants could also consume CO2
In New Scientist the are saying Geothermal power plants could also consume CO2.
Pumping carbon dioxide through hot rocks could simultaneously generate power and mop up the greenhouse gases produced by fossil fuel power stations, according to a new study.
Harnessing geothermal power involves extracting heat from beneath the surface of the Earth. Normally, this means pumping water down through hot rocks and extracting it again. But the new analysis suggests carbon dioxide could extract heat from rocks more efficiently than water.
Eliminating release of CO2 at the source is the way to go. Generating power by doing it is a fantastic bonus. Carbon credits buy us time and channel funds into a huge range of projects that together form a multi-pronged attack on the problem. — DS
