Science & Technology: Supercritical CO2 Could Increase Heat Yield of Geothermal Reservoir

Boosting geothermal yields (eniday)

A new study published in the journal Geothermal Energy used a numerical simulation to study the effect of CO2 sequestration into an aquifer in Louisiana, USA. 

It found that the introduction of supercritical CO2 into the aquifer, as well as reducing atmospheric levels, might also be able to increase the heat yield produced by the aquifer. This finding further advocates the dual use of CO2 sequestration together with geothermal production. 

The Gulf States of the USA have huge quantities of geothermal energy that are still untapped, and accordingly this study could pave the way for the wide-scale development of geothermal power generation in this region.
