New Name, Same Old Coal
This month, a company named Flatlands Energy has been making the rounds at Southcentral Alaska’s electric utilities, cheerily describing a future where coal power is safe and environmentally responsible. We know better. The vision they present of “carbon capture and storage” on a coal power plant relies on unproven technology and a number of false assumptions, and Alaskans are smart enough to see through these claims and refuse new coal development in our state.
While the rest of the United States, and most advanced economies throughout the world, are working to phase out coal usage, Flatlands proposes developing a brand new coal power plant in Matanuska-Susitna Borough. This is not a conversation about mitigating the emissions from existing projects – this would be starting from scratch with coal, fully aware of its many environmental and health impacts. A new open-pit coal mine along with a power plant fitted with carbon capture infrastructure would be constructed near the proposed pipeline to Donlin Mine.
Carbon capture technology on power plants has not been proven successful. In fact, existing projects have been consistently under-performing when it comes to the actual carbon captured. Notably, Flatlands claimed during its presentation at Chugach Electric Association that coal with carbon capture would put out lower emissions than even wind and solar with natural gas backup. However, that claim relies on the system capturing a whopping 90% of carbon emissions, which is completely unrealistic. Petra Nova, the only coal plant to operate with carbon capture in the United States, also aimed for a 90% capture, but likely only captured 55-70% of emissions while it was online. Including methane emissions from coal mining itself also significantly drops the amount of carbon that can be captured.
What’s more, these projects fail consistently on economics alone. Even with substantial government funding, carbon capture projects have not been profitable. Flatlands bets on a future of tax credits that is not guaranteed, and key players like the Mat Su Borough Assembly claim this will reduce the cost of importing liquefied natural gas (LNG). However, a new coal mine and coal power plant would certainly not be online soon enough to offset LNG imports.
Instead of getting distracted by false promises, our electric utilities should continue their work to conserve as much gas as possible and move toward the most cost-effective mix of energy for the Railbelt, which includes 76% renewable energy generation.
Alaskans will not be fooled: coal power is the past, not our future.
