The Hill: "What Can the EPA Still Do on Power Plants?"
In an analysis of West Virginia v EPA, a 2021 issue brief on natural gas co-firing is presented as a policy option to reduce emissions while staying within the bounds of the decision.
One alternative to generation-shifting is co-firing, or the combustion of two kinds of fuel at the same time, which can create a more environmentally friendly product at an existing plant.
“Depending on the level of co-firing that you assume, you could still get quite significant emissions reductions through that approach,” Lienke said.
He cited 2021 modeling by Resources for the Future, which indicates the co-firing approach could be an effective means of emissions reduction, but “almost certainly not as cost-effective as generation shift,” he added.
