NZT Power, a joint venture between bp and Equinor, aims to be the world’s first commercial scale gas-fired power station with carbon capture technology and could generate up to 860 megawatts of low carbon power – equivalent to the electricity requirements of around 1.3 million UK homes.
The NEP, a joint venture between bp, Equinor, and TotalEnergies, is the CO2 transportation and storage provider for the East Coast Cluster.
The front-end engineering design (FEED) phase commenced in April 2022 and has seen Costain planning new systems for both NZT Power and NEP in an integrated programme of activity.
The completed FEED design for NZT Power includes natural gas supply pipework and a high voltage 275kV power network. For NEP, design work focused on the onshore CO2 gathering network. When finished, the c.12km of 22” pipeline will have an initial capacity to transport around 4m tonnes of CO2 per annum to be securely stored under the North Sea.

The Teesside onshore NEP infrastructure will serve the Teesside-based carbon capture projects - Net Zero Teesside Power, H2Teesside and Teesside Hydrogen CO2 Capture – that were selected for first connection to the ECC by the Department for Energy Security and Net Zero (DESNZ) in March 2023 as part of the cluster sequencing process for CCUS. To support this selection, Costain is currently updating the FEED design, due for completion Q2 2024, in readiness for detailed design.
Net Zero Teesside Power and the Northern Endurance Partnership aim to take Final Investment Decisions in September 2024, and aim for first commercial operations from 2027.
Laura Hughes, energy sector director at Costain, said: "This is an exciting and complex project and one that will leave an enormous legacy for the region. It won’t be long before Teesside will benefit from a world-leading, integrated decarbonisation system, with the East Coast Cluster bringing the UK closer to its net zero goals.
"We have designed a CO2 gathering network that is the first in the world to be a wholly above-ground network. This presented interesting design and engineering challenges when considering the properties of CO2 and its ability to liquify at certain temperatures and pressures. However, extensive flow assurance simulations and data modelling has given us a better understanding of the dynamics of CO2 and its behaviours to successfully complete the design for a safe, resilient and efficient network."
