Carbon capture | transport and permanently store CO2
offshore in
the company’s depleted Liverpool Bay gas fields. The East Coast Cluster is a collaboration between Northern Endurance Partnership, Zero Carbon Humber and the Teesside cluster, which includes Net Zero Teesside.
A key enabler for the East Coast Cluster is the
Northern Endurance Partnership, which brings together BP, Eni, Equinor, National Grid, Shell and Total, to develop offshore carbon dioxide transport and storage infrastructure in the UK North Sea, with BP as operator.
The Equinor-led Hydrogen to Humber (H2H) Saltend project can be regarded as Zero Carbon
Humber’s anchor project, establishing a major facility for hydrogen production from natural gas, with carbon capture, at px Group’s Saltend Chemicals Park.
Equinor has recently selected KBR & Tecnimont consortium, Technip Energies consortium and Linde/BOC, to participate in a competition to select a FEED contractor for H2H Saltend, with the aim of choosing one of the three consortia by end 2022 in preparation for a final investment decision in late 2023. The 600 MW H2H Saltend project would be the starting point for a CO2
and H2 pipeline network
to be developed by National Grid Ventures, connecting energy-intensive industrial sites throughout the region, offering businesses the possibility of directly capturing their emissions or fuel-switching to hydrogen. All captured CO2
will be compressed at
Centrica Storage’s Easington site and stored under the southern North Sea using offshore infrastructure shared with the Teesside industrial cluster.
Teesside
As this shared infrastructure is delivered, other Zero Carbon Humber partners will connect to the pipelines. These partners include Drax, which is pioneering BECCS (bioenergy with CCS) and SSE Thermal (working in conjunction with Equinor), which has submitted a development consent order application to the Planning Inspectorate for Keadby 3, a 910 MWe CCGT plant equipped with CCS. SSE Thermal is also progressing plans, with Equinor, for Keadby Hydrogen, which it describes as “the world’s first major 100%-hydrogen-fired power station”, as well as a large-scale hydrogen storage facility at Aldbrough on the East Yorkshire coast. Both of these facilities could be operational by 2030 and are well placed to plug into the East Coast Cluster, says SSE Theemal. Net Zero Teesside (NZT), for which a DCO application has also been submitted to the Planning Inspectorate, includes a CO2
gathering Humber
network with pipeline connections from industrial facilities on Teesside and a combined cycle plant equipped with carbon capture (abated installed capacity 850 MW). The NZT power project, being developed by OGCI members, BP (lead), Eni, Equinor, Shell and Total, was taken over from OGCI Climate Investments. It was formerly the Clean Gas Project, initiated by the now defunct UK Energy Technologies Institute. Also potentially part of the Teesside cluster (but separate from the NZT power project) is a planned 300 MW gas fuelled power plant employing NET Power’s Allam-Fetvedt cycle. This employs oxyfuel combustion (combustion of the natural gas with oxygen rather than air) and uses supercritical carbon dioxide as the working fluid to drive a turbine instead of steam. Called Whitetail Clean Energy, the Teesside Allam-Fetvedt power plant would be located at Sembcorp Energy UK’s Wilton International site, and is being developed jointly by 8 Rivers Capital and Sembcorp Energy UK.
NET Power has recently announced achievement of a major milestone: delivery of power to the ERCOT grid from its 50 MWt Allam- Fetvedt demonstration facility in La Porte, Texas Three maps showing the East Coast Cluster, consisting of projects in Teesside and Humber (see this month’s news).
