Statfjord C changes its power solution to cut emissions
Equinor and partners will replace two gas turbines with heat recovery to produce electric power. This will reduce annual CO2 emissions by 95,000 tonnes.
A new steam turbine will produce electricity based on surplus heat from two gas compressors. This will make the energy consumption more efficient and cut 25 per cent of total annual CO2 emissions on Statfjord C, equivalent to 50,000 cars.
“This is the first time this solution is used on an operated field at the Norwegian Continental Shelf (NCS). I am proud of employees and suppliers that have worked in an innovative way to streamline the energy being used at the platform. This is an important contribution to extend the field’s life to 2040,” says Camilla Salthe, Equinor’s senior vice president for Field Life eXtension (FLX).
Scheduled for start-up in 2026, the new steam turbine will give cost-effective emission cuts. It will be the first time this solution is introduced on the Norwegian continental shelf (NCS).
“Heat recovery for electric power production has been used on new fields, both on the NCS and internationally. Now, for the first time, the solution is introduced on a mature field in production. This is possible due to the development of low-weight solutions,” says Ketil Rongved, Equinor’s vice president for FLX projects.
The project also involves electrification of water injection and emission cuts related to other energy intensive processes on Statfjord C. The project, named “FLX Future Energy” was decided by the Statfjord partnership in July.
This project is one of many measures to cut emissions from the production at Statfjord. For instance, a heat recovery unit on Statfjord B has cut CO2 emissions by 20,000 tonnes every year since 2021.
