The effective capture rate of carbon dioxide (CO2) at a carbon capture installation at the San Juan Generation Station in New Mexico, USA, is exaggerated, according to analysis from the Institute for Energy Economics and Financial Analysis (IEEFA).
Operator of the unit, Enchant Energy, claims that by retrofitting the plant for carbon capture, 90% or more of the emitted CO2 could be captured.
Using ‘real-world evidence’, the IEEFA discovered that the effective CO2 capture rate at the plant – after considering the mine’s methane emissions – would be no more than 72%, assuming that the plant captured 95% of generated CO2.
