Company/Alliance: Wallula Resource Recovery LLC and Edison Mission Group collaborating with Big Sky Carbon Sequestration Partnership, Washington State Department of Energy (DOE), and Washington Energy Facility Site Evaluation Council (EFSEC)
Location: Attalia Industrial Area, Wallula, Walla Walla County, Washington, USA
Feedstock: Coal (Powder River Basin)
Size: 600-700 MW
Capture Technology: IGCC/Pre-combustion
CO2 Fate: Sequestration in basalt formations 1.3 miles underground
Timing: Basalt sequestration demonstration (2007), air emission testing at demonstration plant in Nakoso, Japan (2007), application filed with EFSEC (2007), site certification agreement with EFSEC (2008), financing completed (2009), construction (2009), and commissioning (2013)
Motivation/Economics: The estimated cost is approximately $2.2 billion. They are planning on applying for Investment Tax Credits authorized by the DOE to encourage clean coal gasification technology. The process will cut 65% of carbon dioxide emissions. The Washington Legislature passed a new law in 2007 that requires all new power plants in Washington to be as clean as recently built natural gas power plants or they must sequester the additional greenhouse gases.
Comments: The location has convenient rail and highway access, readily available industrial water supplies, as well as being near both a gas pipeline and high voltage lines. There are two plants ready for construction in the Attalia Industrial Area that burn ethanol and biodiesel.
