Company/Alliance: Naturkraft, owned 50-50 by Norstk Hydro and Statkraft
Location: Kårstø, Rogaland, Western Norway
Feedstock: Natural Gas
Size: 420 MW, 1.2 million tonnes of CO2 annually captured
Capture Technology: Post-combustion
CO2 Fate: Sequestration in seabed and/or EOR
Timing: Powerplant opened Nov 2007, electricity production without carbon capture and storage (2007), investment decision (2008), and commissioning (2011-2012)
Motivation/Economics: The costs of the project are NOK 330 million (US$57 million) for the planning phase, NOK 3.46 billion (US$600 million) for the carbon capture plant, and NOK 1.56 billion (US$270 million) for transportation and storage. The capture rate will be approximately 85%. Five potential storage sites have been evaluated: Heimdal, Karmsundet, Coastal (Kystnært) Utsira, Nordøst Frigg, and Sleipner.
Comments: The plant will need to be retrofitted with a capture facility that will be ten times as large as the largest existing plant for separation of CO2 from gas turbine exhaust. Annual operating costs assuming 8000 hours of operation are estimated to be NOK 370 million (US$64 million), leading to a cost of NOK 700 (US $121) per tonne of CO2 abated. CO2 maybe provided for EOR in Statoil Volve Field.
