JCB upgrades its diesel engine to use hydrogen fuel

JCB, one of the world leaders in the production of construction and special equipment, continues to move towards decarbonization of its model range.

This is the # technique that is mainly used for light work, or indoors. But for heavy construction work, as believed in

True, it is worth mentioning that many of JCB’s competitors do not agree with this approach, and create battery tractors and excavators. But more on that in the following articles. Of course, the main opponent of hydrogen technology in land transport, which is quite natural, is the head of #tesla # Ilon Musk, who once said that hydrogen engines are “

But in fact, the technology of using hydrogen as a fuel was not invented today. This idea is over 200 years old! Back in 1806, the French engineer François Isaac de Rivaz, having received hydrogen through electrolysis of water, thought about using it as a fuel. But the first officially registered patent for a hydrogen internal combustion engine was issued in England in 1841. A working prototype of a hydrogen # ICE was created in Germany in 1852. But as we know from history, at that level of development of this technology, it could not win a place for itself in the competition with the then emerging battery electric vehicles, and then gasoline and diesel cars.

But a lot of time has passed, technologies have made a truly cosmic leap. Hydrogen is already being seen as the # fuel of the future, replacing diesel in heavy land, rail and air transport. And JCB wants to implement it in its excavators and tractors.

Engineers at JCB Power Systems, an engine plant in Derbyshire, UK, developed the first hydrogen engine in the construction machinery industry. By using and adapting diesel engine technology, with readily available components, hydrogen is burned and power is transmitted just like an old diesel engine. # a prototype backhoe loader equipped with a new hydrogen engine can do everything that its diesel counterpart.

As noted by JCB, this technology is much less complex than hydrogen fuel cell technology, and nothing but water vapor comes out of the tailpipe. As with hydrogen fuel cell technology. The hydrogen is contained in two high-strength cylinders made of composite materials. They, in turn, are covered with a sturdy cover to prevent accidental damage on the construction site.

Dear readers, what do you think? What will become the main energy carrier in the future construction equipment — # battery or # hydrogen? The fact that diesel will leave this segment of transport is just as unambiguous as in the case of other transport. Now in Europe, along with conventional transport, there is a policy of decarbonization and construction equipment. So the bottom line is absolutely clear. The only question is which option will prevail in this segment of transport and technology.
