International MSc student named co-inventor on Swansea CO₂ heat-pump patent
International Mechanical Engineering MSc student Brian Sagini has joined Dr Rajesh Ransing as a co-inventor on a Swansea University patent application for an advanced CO₂ heat-pump design.
The work targets higher-temperature, high-efficiency heat pumps for industrial decarbonisation. The team’s approach integrates an ejector operating in the superheated region with system-level efficiency measures, aiming to accelerate progress toward pilot-scale demonstration.
Patent application:
GB Patent Application No: GB2515031.9
Title: Transcritical CO₂ Heat Pump
Date filed: September 2025
Dr Ransing said, “Brian’s contribution exemplifies how our students help create real-world intellectual property while advancing clean-heat technologies.” Brian added, “It’s exciting to apply the core concepts I learnt in my MSc project to an innovation with clear industrial impact. The breadth of Swansea’s Mechanical Engineering modules encourages open thinking, and this gave me the confidence to contribute creatively to solving a real-world challenge.”
Dr Ransing, who also leads the Enterprise, Partnerships and Innovation (EPI) group at the Zienkiewicz Institute, notes that “early discussions, even when ideas are still at the conceptual stage, are very important.”
For any innovation, colleagues and partners can engage with the EPI group or contact Swansea’s IP and Commercialisation team, headed by Rhys Bowley, at innovations@swansea.ac.uk.
