Carbon capture and storage
The Norwegian government and StatoilHydro have also reached agreement on the construction of a full-scale capture plant for carbon dioxide at Mongstad. A first development stage, able to capture 100,000 tonnes of carbon dioxide annually, is scheduled to be in place at roughly the same time as the CHP station begins operation in 2010.
Stage II involves a full-scale facility able to capture carbon dioxide from both the CHP station and other relevant emission sources at or around the refinery.
A final decision on the size and type of the full-scale plant will be taken in 2012, with detail engineering and construction scheduled to start immediately afterwards.
A shared solution for Troll and Mongstad – high energy efficiency
This CHP station is intended to strengthen and develop Mongstad further as an industrial facility through more efficient energy generation.
Once the combined heat and power station is on line, it will be possible to make use of energy which remains unbe utilised at present.
The new generating installation will have a capacity of roughly 280 megawatts (MW) of electricity and about 350 MW in the form of heat.
Electricity to Troll
In addition to supplying the refinery, this station will also provide power for the Troll A gas platform and the Kollsnes processing plant under contract with the Troll licence. It will burn natural gas from Troll and fuel gas supplied by the refinery.
The facility will ensure long-term electricity deliveries to Troll, where the demand for power is set to rise because more compressor capacity will be needed to transport gas as reservoir pressure declines.
A planned gas pipeline from Kollsnes to Mongstad accordingly represents part of the production and landfall system for the Troll field. This will provide fuel to generate electricity which can be used in turn to power Troll A and the Kollsnes facility.
The mongstad CPH statoio will strengthen Norway’s overall energy balance and relieve a particular power shortage in the Bergen region.
This represents a solid project in industrial and environmental terms.
The first turf was cut in mid-January 2007, and the CHP station is due to be ready in 2010. It will be built, owned and operated by Denmark’s Dong Energy utility.
