Teesside University and Durham University are working with industry leaders H2CHP Ltd and Johnson Matthey on an ambitious 12-month project: designing and simulating a hydrogen-fuelled Free-Piston Engine Generator (FPEG) to provide clean, efficient cold-ironing for ships in port.
The maritime industry is a major contributor to air and noise pollution in port areas. Ships docked in ports typically run onboard diesel generators to power essential systems, releasing harmful emissions. Upgrading port electrical grids to meet the high energy demands of large vessels is costly and time-intensive, while installing and maintaining shore power infrastructure presents financial barriers for port authorities. Additionally, traditional anchoring practices – where vessels wait offshore – make cold-ironing connections difficult to implement. These challenges create an urgent need for a cost-effective, low-emission alternative to conventional shore-side power systems.
Through the Research England Hydrogen Innovation Project, Teesside University and Durham University are collaborating with H2CHP Ltd and Johnson Matthey to develop a hydrogen-fuelled Free-Piston Engine Generator (FPEG) for clean cold-ironing. This innovative system will supply ships with sustainable shore-side power while docked, removing the need for onboard diesel generation. The project combines advanced simulation tools, hydrogen research facilities and engine laboratories to analyse combustion performance, optimise power transfer and minimise emissions. In parallel, economic and environmental assessments are being undertaken to ensure the solution is commercially viable and supports long-term sustainability goals.
The hydrogen-fuelled FPEG will significantly reduce harmful emissions in ports, delivering lasting environmental benefits to surrounding communities. By enabling cleaner, greener operations, the technology enhances the competitiveness of UK ports, attracts hydrogen-powered vessels and supports operational efficiency. The project also stimulates economic growth through job creation in hydrogen technology design, manufacturing, and deployment. In line with the Research Excellence Framework, the work demonstrates measurable environmental, economic and industrial benefits, strengthening the UK’s position as a global leader in clean maritime innovation.
