Norway's state-controlled Equinor and its partners have decided to invest in electrification of Troll West, part of one of the largest oil and gas fields in the Norwegian North Sea.
Partial electrification of the Troll B platform, and full electrification of Troll C, will mean that the platforms' power demand will be met from shore. It will enable the two gas export compressors on Troll C, which are driven by gas turbines, to be replaced by electric motors.
The project will reduce CO2 and NOx emissions at a cost of around 7.9bn Norwegian kroner ($1bn). It will receive NKr520mn from the Norwegian NOx fund.
"Troll B will be partially electrified in the first quarter of 2024, and Troll C will be fully electrified by the second quarter of 2026," Equinor said. The Troll A platform, which came online in 1996, was the first electrified installation offshore Norway.
Equinor last year received government consent for 10 more years of production at Troll B, with a view to developing gas production. Today it said that "oil production at Troll is in the tail end phase, whereas only half of the gas resources have been produced".
Equinor operates Troll with a 30.6pc stake. State-owned Petoro holds a 56pc interest, Shell 8.1pc, Total 3.7pc and US upstream firm ConocoPhillips 1.6pc.
"Continued electrification of oil and gas fields using power from shore is important if Equinor is to keep its pledge of a 40pc emission cut by 2030," the Norwegian Petroleum Directorate (NPD) said.
Equinor, Shell and Total are among the oil and gas firms that have announced their intentions to become net-zero companies by 2050. They have pledged to cut emissions in the coming years and decades through investing in clean energy solutions, but also through developing lower-emissions and cheaper oil and gas resources.
Equinor will present its updated energy transition strategy in June. In February, the company confirmed its earlier guidance that it expects its oil and gas production to grow by about 3pc/yr in 2020–26 "based on current forecasts". The firm is also a leading offshore wind developer.
