Fifty years after construction began, the terminal is entering a new phase. Although the flow of oil and gas is well below the 1980s peak, it looks likely that the site will continue to be a hub for energy developments far into the future.
The management of the terminal passed from BP to EnQuest in late 2017, with the new operator focused on extending the life of existing oilfields and keeping the terminal competitive. One of the first moves is the construction of a new stabilisation facility that will be better suited to current and future production rates. That will allow the old process area to be retired, freeing up a large area of land for other possible facilities.
However, EnQuest and its partner, Veri Energy, have been looking at other possible developments that stem from the need to decarbonise both the terminal and the global economy. The possibility of powering the terminal using electricity generated in Shetland’s wind farms is on the table, but there would be even more substantial gains from using the same renewable energy to supply the electricity needed by offshore production platforms, which will probably continue to operate for at least another two decades.
Those same windfarms, both onshore and – if developed – offshore, might also power a plant producing ‘green’ hydrogen, another ingredient in a future zero-carbon energy mix. The ambition is annual production of a million tonnes of hydrogen. There is also interest in producing ‘green’ ammonia.
These could be exported to wherever in the world they were required. Sullom Voe could thus make a very significant contribution to the reduction of carbon emissions in many fields, including transport and industry.
Also being considered is the use of the terminal as a hub for carbon capture and storage, re-purposing depleted oilfields. The port, with its deep-water jetties, is an obvious asset, and so is the network of undersea pipelines connecting the terminal to those oilfields. Initial studies have suggested that up to 10 million tons of CO² could be put into storage annually. Veri Energy has been offered four licences for this project, awarded in 2023 by the North Sea Transition Authority in its first licencing round.
