The new injector design has two iterations: a high-pressure direct injector capable of fuelling applications from 25 to 200 kW per cylinder; and a high-flow port injector capable of “very high” gaseous fuel flow rates.

The intention is to market Terex Advance Commander Series trucks with diesel and hydrogen engine options once series production of the Cummins ‘X15H’ begins as planned in the latter part of this decade.

About the retrofit of the H2 ICE engine, Lord Bamford, JCB Chairman, said: “We have retrofitted this vehicle with a JCB hydrogen engine to demonstrate how simple it will be to convert existing vans and to show that it is not only construction and agricultural machines that can be powered by hydrogen. While converting vans will not be for JCB to do, it does prove there is something else other than batteries that can work very effectively.”

Representing an investment of approximately USD170m, the 200,000-square-foot plant will produce up to 100,000 high-pressure hydrogen vessels annually when it is completed.

At the company’s East Asia Research & Development Centre, the upcoming ‘X15H’ engine was presented alongside Meritor axles, aftertreatment systems, and ‘Endurant’ transmissions.

Under the agreement, charging stations for Commercial Vehicles (CVs) will be placed every 120km along the EU’s main highways by 2028, whilst hydrogen refuelling stations will be installed at least every 200km by 2031.

The joint venture, which will make use of Westport assets and intellectual property, will receive an initial USD28m investment from Volvo, giving it a 45% stake.

This report is based on trips to the Turbo Technologies facility in Huddersfield and to the third Hydrogen for Life conference in London, both taking place in June 2023.

The American manufacturer claims the new alloy will make its engines more durable and efficient than was previously possible. 

Westport executives David M Johnson, Scott Baker, and Charlie Ker spoke to T&BB about the 'H2-HPDI', which enables a diesel combustion engine to run effectively on hydrogen fuel - reducing emissions by up to 98%.

The truck – a Peterbilt Model 579 – featured a Cummins ‘X15H’ engine, providing up to 500 horsepower (372 kW) and up to 1,900 lb-ft torque.

In 2022, the Canadian manufacturer of gas engines made USD305.7m, a 2% fall compared to revenues (USD312.4m) reported in 2021.
