Design & Development of CO2 Condenser

The following summary is not intended as a complete or definitive specification of the requirement. A purpose of this engagement notice is to seek information from the market to help refine our understanding and aid the development of a future specification.

UKIFS is seeking experts to support the design and development of a CO2 condenser that is part of the STEP power cycle. This is because a high-performance CO2 condenser is critical to the efficiency of the STEP powerplant (supercritical and/or transcritical CO2 power generation cycles are currently the preferred concept for the STEP prototypic plant).

The proposed technical and operating conditions of the proposed CO2 condenser are: •Operating pressure is between ca. 60-100 bar for the CO2 stream •Operating inlet temperature will be between ca. 50 - 110°C. The outlet temperature will be between ca. 20-25 °C for the CO2 stream. •Thermal duty is in the range of 1-2 GWth. •The equipment must comply with UK pressure equipment regulations.

Please be aware, any future procurement activity associated with the CO2 condenser PME will likely occur in Tranche 2B of STEPs programme. T2B is due to start in April 2029 and is subject to formal sign-off of our design (T2A) and agreement of the whole T2B plan For more information about this opportunity, please visit the Delta eSourcing portal at: https://ukifs.delta-esourcing.com/tenders/UK-UK-Culham:-E...
