The BP-led Northern Endurance Partnership (NEP) project, which aims to develop carbon dioxide storage infrastructure off the north-east coast of England, plans to move into front-end engineering and design swiftly if its newly announced funding bid is successful.
A “large amount” of conceptual design work, known as pre-FEED, has already been completed on the proposed development solution, BP told Upstream on Monday.
The scheme will include newbuild pipelines to carry CO2 to the Endurance underground reservoir, about 80 kilometres offshore, plus “associated facilities” located above surface to manage the injection of the climate-altering gas.
BP said the Endurance reservoir is unique in the North Sea, having had a specific appraisal well drilled for the modelling of CO2 injection.
The appraisal well has formed much of the basis for the subsurface static and dynamic modelling the NEP team has been working on for the past 18 months, the company said.
On Monday, the Northern Endurance Partnership (NEP) consortium announced it had applied for UK government funding to kickstart the development of the pipelines and infrastructure intended to capture and store CO2 emitted from clusters of heavy industry on the River Tees and the Humber Estuary.
“Following a successful funding application, the project will shortly move into the FEED phase, where more detailed engineering, commercial assessments and survey work will be completed,” BP told Upstream.
This will cover costs through to the point where the partnership takes a final investment decision, but this remains conditional on “legislated business models and sufficient technical and commercial maturity”.
The plan is to capture CO2 emissions from the proposed Net Zero Teesside (NZT) and Zero Carbon Humber (ZCH) schemes and pump into saline aquifers beneath the UK North Sea for permanent storage.
The overall aim is to decarbonise large centres of industry around the River Tees near Middlesbrough and further south around the Humber estuary.
No details about the size of the platform that will be required have been released yet.
However, the cancelled White Rose carbon capture project could provide clues about what the Endurance offshore platform might look like.
A FEED report for the offshore element of that project carried out by consultancy Genesis Oil & Gas for client National Grid put a proposed jacket weight at about 2930 tonnes with 1400 tonnes of piles.
The main topsides modules weight was assessed as 2990 tonnes while the future module installation weight was assessed at almost 1600 tonnes.
The project explored the feasibility of capturing carbon emissions from a coal-fired power station next to Drax’s existing power plant in Yorkshire and storing them under the North Sea.
