Cummins, in collaboration with technology partners like Johnson Matthey, PHINIA, and Zircotec, led 'Project Brunel' to develop hydrogen internal combustion engine technology for medium-duty trucks and buses. This innovative project, match-funded by the UK government and facilitated by the APC UK, resulted in the successful creation of a 6.7-liter hydrogen internal combustion engine that significantly reduces carbon emissions and NOx levels. The project showcased the power of industry collaboration and commitment to decarbonization. Cummins is optimistic about the technology's potential beyond 2035 and 2040 for commercial vehicles. The scalable design of the engine also allows for heavy-duty applications, with Cummins already working on a 15-liter version. Additionally, Cummins' investment in a new Powertrain Test Facility reflects its dedication to advancing various powertrain technologies, including hydrogen, for multiple industries.
