According to Ricardo, it has produced a prototype internal combustion engine and sent it off to Cummins and BorgWarner, who are partners in the Avanced Propulsion Centre project.

Westport has committed to investing up to USD10m a year over the next decade to support the construction and development of the new site, which it will undertake together with the local authority.

JCB has stated that retrofitting the hydrogen engine - which is made for construction and agricultural machinery - into the Mercedes truck took just a few days.

The Liverpool-based retrofit firm says it is initially contracted by Aberdeen City Council to convert 35 vehicles, including waste collection vehicles and road sweepers.

Having invested GBP 100 million in a project to produce super-efficient hydrogen engines, this multi-year project has reached a major production milestone with its 50th hydrogen combustion engine coming off the group engine line in Foston, UK.

Its sites in Michigan and Germany will now be able to accommodate original equipment manufacturers looking to test internal combustion engines running on hydrogen fuel.

The two companies will work together to make an emissions aftertreatment system for Westport's hydrogen "high pressure direct injection" (HPDI) product.

Farizon Auto, the new energy commercial vehicle brand name of Zhejiang Geely New Energy Commercial Vehicle Group (a subsidiary of Zhejiang Geely Holding Group of Hangzhou), has raised USD300m in a pre-A round of fundraising, which it said will be used to strengthen its range of low- and zero-emission vehicles.

The proposed measures, applying to cars, vans, trucks and buses, are set to come into effect in 2025 and 2027, but they have been criticised by ACEA for being over-stringent, especially for heavier vehicles.

Sylvain Blaise, President of the Iveco Group Powertrain Business Unit at IAA said, in launching a range of new powertrain products for the CV industry: "FPT Industrial is ready for the future."

The joint demonstration programme applied Westport’s ‘H2 HPDI’ fuel system to Scania’s 13-litre ‘CBE1’ diesel engine platform, which achieved a peak brake thermal efficiency of 51.5%, compared to a 50% diesel baseline.

Cummins used the IAA to reveal its new medium-duty hydrogen-fuelled internal combustion engine, which has been developed as part of the European H2-ICE project and Destination Zero Initiative.
