Healy Clean Coal Project
From Wikipedia, the free encyclopedia
Healy Clean Coal Project was a clean coal technology demonstration program consisting of a coal fired electrical power station located in Healy, Alaska in Denali Borough. The project was a demonstration of the TRW Clean Coal Combustion System and the Babcock & Wilcox/Joy Spray Dryer Absorber (SDA) System designed to reduce oxides of nitrogen (NOX) and sulfur dioxide (SO2) emissions while burning a variety of coal types, including waste coal. The plant still operates as Healy Unit 2 but without the emissions-reduction technology.

The project constructed a plant adjacent to Golden Valley Electric Association (GVEA) 25 MW coal plant Healy Unit 1. Construction occurred from 1995 to 1997 at a cost of around $300 million. The facility operated briefly following its construction as part of the demonstration program, but has been shut down since 2000.[1] The research project is considered "complete" by the Department of Energy. The plant was sold in 2012 to the GVEA to resume power production.[2] It restarted in 2015, only to close the next year after an explosion. It resumed commercial operation in November 2018.[3]
Healy Unit 2 will be shut down in 2024 and Unit 1 will receive an emissions control system.[4]
