Project: Naturkraft Kårstø
Company/Alliance: Naturkraft, owned 50-50 by Norstk Hydro, Statkraft and Gassnova
Location: Kårstø, Rogaland, Western Norway
Feedstock: Natural Gas
Size: 420 MW, 1.2 Mt/yr
Capture Technology: Post-combustion: Amine
CO2 Fate: Sequestration in seabed and/or EOR
Timing: Original timing: Power plant opened November 2007, electricity production without carbon capture and storage (2007), investment decision (2008), and commissioning (2011-2012). Delayed in 2009 with no update on when it will start.
The costs of the project are NOK 5275 million ($950 million US) (2006) 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.
In March 2010 Gassco and Gassnova presented an Kårstø Integration pre-feasibility study. The objective of this Kårstø Integration Pre-feasibility Study was to describe potential integration opportunities at Kårstø including technical, environmental, safety, commercial issues and arrangements.
In the National Budget for 2011, presented in October 2010, were there no grants to continue the process on Kårstø. The government stated then that they will consider the future of the project during their work on the new climate policy this year.
The EFTA Surveillance Authority (ESA) decided to authorise state funding to Gassnova SF (March 2009) in order to cover the costs of establishing the CCS project for 10 years. 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 ton of CO2 abated. CO2 maybe provided for EOR in Statoil Volve Field.
