Sembcorp collaborates on UK net zero power plant

Jul 19 2021

The company is exploring a potential 300MW Net Zero emissions NET Power station at Wilton International, Teesside with carbon capture technology.

Sembcorp, through its UK subsidiary Sembcorp Energy UK (SEUK), is collaborating with Zero Degrees Whitetail Development, the UK subsidiary of US innovation firm 8 Rivers Capital, to explore the development of the UK’s first Net Zero emissions NET Power station at SEUK’s Wilton International site on Teesside.

Called Whitetail Clean Energy, the project is expected to produce about 300 megawatts (MW) of clean, efficient, low-cost electricity, with potential expansion options in the future. The Wilton International site in northeast England offers convenient port and pipeline access, where all Whitetail’s captured carbon dioxide can be conveniently transported to UK sequestration sites to be permanently stored in secure geological formations deep under the North Sea.

Subject to UK regulatory support and if finalised to proceed, the collaboration agreement is an important milestone in advancing the decarbonisation of Teesside towards Net Zero, through the deployment of new technology. The Whitetail facility is expected to harness the Allam-Fetvedt Cycle (AFC), a new type of power cycle pioneered by 8 Rivers Capital and NET Power, LLC, a clean energy technology company in the United States.

The process combusts natural gas with oxygen, rather than air, and uses supercritical carbon dioxide as a working fluid to drive a turbine instead of steam. As a result, all air emissions, including traditional pollutants and CO2, are eliminated and pipeline-quality CO2 is produced so that it can be captured and stored offshore, making Whitetail a Net Zero emissions plant.

Sembcorp is one of the largest Singapore homegrown renewable energy players with more than 3,300 megawatts (MW) of renewable energy capacity globally. The company’s renewable energy portfolio comprises wind, solar and energy storage in key markets such as Singapore, Vietnam, China, India and the United Kingdom.
