Google intends to use electricity from the 400-MW power plant in Decatur, Illinois, to operate nearby data centers. Carbon capture will eliminate some of the plant's emissions, but how much remains to be seen.
Carbon dioxide from Google’s power plant will be injected into the same geological storage formations already used by ADM’s ethanol facility. The site is the location of the first long-term CO2 storage well in the U.S.
Typically, around 2,000 metric tons of CO2 are sent into the well every day. But injections there were halted in 2024 when salty brine, which stores dissolved CO2 deep underground, was found to have migrated into “unauthorized zones,” according to the EPA. ADM said the leak was the result of corrosion at a monitoring well, E&E News reported, and they’ve since resumed injections.
A recent study of 13 CCS facilities representing 55% of all captured carbon shows that most aren’t living up to expectations.
