Wraps come off brand-new JCB hydrogen internal combustion engine at Conexpo 2023

JCB’S £100 million project to produce super-efficient hydrogen engines has this week been given its international debut at one of the world’s biggest construction equipment fairs.

A team of 150 engineers is working on the pioneering initiative to develop hydrogen combustion engines – and more than 50 prototypes have already been manufactured at JCB’s UK engine plant.


The wraps came off the brand-new JCB hydrogen combustion engine – the company’s zero-carbon emissions solution for construction and agricultural equipment – at the Conexpo 2023 show yesterday in Las Vegas as part of the International Fluid Power Exposition (IFPE).

JCB chairman Anthony Bamford, who is leading the project to develop JCB’s hydrogen technology, said: ‘The JCB engineering team has made enormous strides in a short space of time to develop a hydrogen internal combustion engine. As the first construction equipment company to develop a fully working combustion engine fuelled by hydrogen, I’m delighted we are now able to present this technology on the international stage.’

Prototype JCB hydrogen engines are already powering backhoe loader and Loadall telescopic handler machines. JCB have also made a major breakthrough in proving the wider appeal of hydrogen combustion technology by installing one of the super-efficient hydrogen engines in a Mercedes 7.5-tonne truck – a retrofit which was completed in just days.

JCB have also unveiled their own designed and built mobile refuelling bowser to take the fuel to the machines. The bowser can carry enough hydrogen gas to fill 16 hydrogen backhoe loaders and is able to be transported either at the back of a modified JCB Fastrac tractor or on a trailer.

Lord Bamford said: ‘The JCB engineering team has gone back to first principles to completely re-design the combustion process to work for hydrogen. In doing so they have achieved two major things: secured JCB’s place in history as the first construction equipment company to develop a fully working combustion engine fuelled by hydrogen and steered us towards the production of a landmark 50 hydrogen combustion engines.’

JCB’s commitment to reducing emissions goes back almost 25 years and the latest diesel engines designed to comply with European Stage V regulations have already delivered a 97% reduction in NOx emissions since 1999 and a 98% reduction in particulates. In addition, JCB’s drive to reduce fuel consumption means today’s JCB machines use 50% less fuel on average than those manufactured more than a decade ago. This has saved 16 billion litres of fuel – equivalent to 53 million tonnes of CO2.

JCB have also been at the forefront of electric technology development to meet customers’ demands for zero-carbon products. While battery electric is suitable for smaller machines which do fewer hours and typically use less fuel, larger machines have a higher energy requirement. This would result in larger batteries, which would take longer to charge, making them less suitable for machines which work multiple daily shifts and do not have the available downtime to recharge.

As a result, JCB have concentrated their development of electric machines on their compact range, including the 525-60E Loadall telehandler and the 19C-1E – the world’s first electric mini-excavator. As the company examines future fuels which deliver zero emissions, it says it has left no stone unturned in its search for a mobile fuel which can be taken to the machine, ensuring maximum uptime and fast refuelling. HVO, biogas, E-fuels, ammonia, and hydrogen have all come under the microscope. Indeed, JCB engines have been approved for use with HVO since Stage IIIB / Tier 4i engine legislation came into force.

Lord Bamford continued: ‘The majority of these alternative fuels require the production of hydrogen to make, so it makes perfect sense to use hydrogen in the first place because it is a clean zero-carbon fuel which can be produced from renewable energy. Hydrogen also offers a potential solution to the challenge of batteries on larger machines; it allows for fast refuelling and is a mobile fuel solution, allowing fuel to be taken to the machine.’

As part of their hydrogen development, JCB have also investigated its use in fuel-cells and in July 2020 unveiled the construction industry’s first ever hydrogen-powered excavator – a 20-tonne 220X.

For the time being, however, the company has concluded that fuel-cells are too expensive, too complicated and not robust enough for construction and agricultural equipment. In challenging the JCB engineering team to think differently using existing technology in a zero-carbon way, the JCB hydrogen engine was born.

Lord Bamford said: ‘The unique combustion properties of hydrogen enable the hydrogen engine to deliver the same power, the same torque, and the same efficiency that powers JCB machines today, but in a zero-carbon way.

‘Hydrogen combustion engines also offer other significant benefits. By leveraging diesel engine technology and components, they do not require rare earth elements and critically, combustion technology is already well proven on construction and agricultural equipment. It is a technology which is cost-effective, robust, reliable and well known throughout not just the construction and agricultural industry, but the whole world.’
