Amarinth Awarded Innovate UK Grant to Develop Next-Generation Multistage Cryogenic Pump
Amarinth’s multistage cryogenic pump for LNG applications (Amarinth Ltd.)
Innovate UK’s new funding underscores its confidence in Amarinth’s engineering excellence and entrusts the company to meet the growing demand for modern, efficient pump technology in the low temperature fuel sector.
Leveraging its proven cryogenic expertise, including recent projects replacing obsolete single stage pumps, Amarinth will design and prototype a multistage pump capable of handling liquefied natural gas at approximately -162 °C. Departing from legacy designs, the new pump will incorporate state of the art CFD designed hydraulics and bespoke impellers, ensuring each stage operates at its optimal duty point. Key objectives include:
- Advanced pump design: A compact, vertical multistage pump with CFD optimised impellers and casing, specifically tailored for LNG service.
- Improved efficiency: Bespoke design techniques to run each stage near its Best Efficiency Point (BEP), avoiding the up to 25% inefficiency often seen in heritage pumps, reducing energy use and CO₂ emissions over the pump’s lifetime.
- Cryogenic robustness: Selection of materials and seal systems proven for cryogenic duty (stainless alloys and low temperature carbon steels) to retain strength and integrity at -162 °C.
- Future-ready applications: A platform adaptable to hydrogen and carbon capture duties. Amarinth already holds “Fit for Hydrogen + Carbon Capture, Usage & Storage” (F4H2+CCUS) certification, meeting the standards for tomorrow’s energy sectors.
“Innovate UK’s support reflects its confidence in Amarinth’s ability to deliver groundbreaking pump solutions,” said Oliver Brigginshaw, Managing Director of Amarinth. “This project builds on our cryogenic expertise, such as replacing a legacy argon pump operating at -186 °C, and our track record of bespoke design. By applying modern engineering to multistage cryogenic pumps, we will help the industry transition to cleaner fuels. LNG is a lower carbon alternative to traditional fossil fuels, but only if handled safely and efficiently. Our goal is to set a new standard in LNG pumping: a highly efficient, reliable pump that can later evolve for hydrogen and carbon capture applications.”
With this grant, Amarinth will develop a production ready, commercially viable pump that meets evolving industry needs and accelerates the energy transition toward greener, low temperature fuels.
