OSLO -- StatoilHydro has submitted its plan for carbon capture at Mongstad to the Ministry of Petroleum and Energy and the Ministry of the Environment.
In connection with establishing the Mongstad energy project, StatoilHydro and the Norwegian government entered into an implementation agreement. Under this agreement StatoilHydro prepared an overall plan for future carbon capture at Mongstad, north of Bergen (master plan).
The purpose of the master plan is to provide the best possible basis for the further process with full-scale carbon capture from the combined heat and power (CHP) station and other substantial sources at the refinery, the company says. In addition to the CHP station is the refinery's cracker considered suitable for carbon capture.
The report describes the facility, technology, and the most important risks associated with realizing full-scale carbon capture. The plan addresses the principal challenges and summarizes the need for studies and verification of individual technical solutions.
The master plan confirms that carbon capture is possible and describes two main alternatives as to how this can be done at Mongstad:
- Alternative 1 allows carbon capture from the CHP station as quickly as possible based on the amine technology available today, normal industry practice for safe and rational project performance and an acceptable HSE risk level. Carbon capture from the cracker follows based on stepwise technology development.
- Alternative 2 allows simultaneous development of carbon capture from the CHP and the cracker, based on a stepwise technology development.
At full capacity, the facility can store three million metric tons of CO2 per year, removed from natural gas in the gas fields Sleipner in the North Sea, Salah in Algeria, and Snøhvit in the Barents Sea. In these projects, carbon dioxide is separated directly from the wellstream for reinjection into suitable reservoirs.
