Amarinth wins Innovate UK grant to develop next-generation multistage cryogenic pump

8/19/2025

Amarinth, a world-leading, net-zero designer and manufacturer of low lifecycle cost centrifugal pumps and associated equipment—primarily for the offshore and onshore oil and gas industries, nuclear and renewable energy generation, defense, desalination, process and industrial markets—has been awarded a £500,000 grant by Innovate UK to develop an advanced multistage centrifugal pump for cryogenic LNG applications.

This award builds on Amarinth’s previous success in securing a £250,000 grant to refine its design and production processes for highly energy‑efficient pumps, which culminated in the launch of an industry‑leading molten sulfur pump. 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‑optimized 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°
  • 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.
