Future Low-emission Ammonia Marine Engines (FLAME)

1 Sep 2025 to 31 Mar 2026

Awarded
£414,512
Total cost £592,161

This project will deliver an Ammonia Auxiliary Engine retrofit solution, allowing shipping companies to eliminate auxiliary emissions whilst reducing cost and not adding risk to vessel operations. At the heart of this solution will be the Carnot Engine. Whereas most internal combustion engines are just 25 -- 35% efficient, a Carnot Engine operates at 72% ...

Shoreside Power from Optimised Hydrogen Lifecycle (SPOHL)

1 Apr 2024 to 31 Mar 2025

Awarded
£542,941
Total cost £775,630

Shoreside Power from Optimised Hydrogen Lifecycle (SPOHL) is an ultra-efficient, zero-emission system for cold-ironing with long-duration, bulk energy storage to balance the seasonal variation in renewable energy systems. This enables it to be an entirely stand-alone system with no need for a grid-connection. It brings together novel technologies that cov...

Novel High-Efficiency Ammonia engine Technology for Heavy Duty marine applications (HEAT-HD)

1 Mar 2024 to 28 Feb 2025

Awarded
£595,648
Total cost £850,926

HEAT-HD is a game-changing high-temperature liquid-ammonia (LNH3) powered engine technology with 70% BTE. Targeting marine propulsion systems and Auxiliary Power Units (APUs) and shore-side power generation units up to 10MW. LNH3 has clear economic and operational benefits for maritime applications as it offers the energy storage density and true zero emi...
