Brunel University of London is leading a significant initiative to develop net-zero emissions, affordable, ultra-efficient hydrogen-powered engines for heavy-duty vehicles, marine vessels, aircraft, and other challenging sectors. While electric engines contribute to the UK's net-zero carbon emissions target, they are not suitable for larger vehicles and machinery used in industries like farming and construction. This underscores the importance of hydrogen as a key clean energy solution for these sectors. The project, supported by UK Research and Innovation (UKRI), brings together Brunel's expertise in hydrogen engine research with AIE and MAHLE Powertrain's specialized knowledge in rotary engines. The collaboration aims to drive advancements in clean propulsion technologies. The £1.3 million funding from UKRI, matched by AIE and MAHLE Powertrain, highlights the dedication to accelerating sustainable technologies. This effort is part of UKRI's wider Prosperity Partnerships scheme, which aims to foster partnerships between businesses and universities to tackle significant industrial challenges. This project is a proactive step towards transforming research into practical solutions that can positively impact society by reducing carbon emissions and enhancing access to innovative technologies.
