Energy specialist Eni UK has announced the launch of its new strategy to decarbonise industrial processes in the South East of England and the Thames Estuary area, near London.
Revealed today (21st Nov), the Bacton Thames Net Zero (BTNZ) Cooperation Agreement aims to harness carbon capture and storage (CCS) to reduce emissions across a number of sectors including power generation and waste disposal.
According to Eni, the project will initially capture, transport and store six million (scaling up to ten million) tonnes per year of CO2 emitted from the Bacton, wider Thames Estuary and potentially north-west European regions into the Hewett depleted gas field.
Located 20 miles off the North Norfolk Coast in the North Sea, the gas field has the capacity to store 330m tonnes of CO2.
In preparation for its CCS strategy, Eni submitted plans in 2019 to decommission the field and to remove all installations. This was followed by an application by the company for a carbon storage license for the site in September 2022, expected to receive approval in Q1 2023.
Set to begin operations as early as 2027, the Eni UK-led BTNZ initiative is supported by industry partners including Progressive Energy, North London Waste Authority, SSE Thermal and Fluxys.
“Eni UK will play a pivotal role in the project and is already actively planning the transportation and storage of CO2 from its partners to the depleted Hewett gas field,” said the company in a statement.
The project builds upon Eni UK’s experience guiding HyNet in the Liverpool Bay area for which it received a CCS license in 2020.
HyNet North West uses existing pipelines in the region to transport CO2 from industry before storage in depleted hydrocarbon reservoirs located around 20 miles offshore in the bay.
gasworld understands that the project could help reduce CO2 emissions by up to ten million tonnes a year by 2030.
Commenting on its HyNet initiative, Nicolo Aggogeri, Managing Director at Eni UK, said, “We saw that we could give new life to our existing infrastructure, maximising the value of our asset with a circular economy approach.”
“Instead of bringing gas from offshore to onshore, we are bringing CO2 from onshore to offshore. The carbon that arrived with the methane molecule is sent back to the reservoir from where it originated through the CO2 molecule.”
“Eni took the opportunity to have such an asset so close to the market demand for decarbonisation, with excellent cost and deliverability benefits for repurposing versus a new-built facility for CO2 storage.””
