World First: JCB Launches Production 3CX Hydrogen Backhoe Loader

JCB has taken the wraps off the 3CX Hydrogen, the world's first production-series backhoe loader powered by a hydrogen combustion engine. The machine marks a significant milestone in the construction equipment industry's shift toward zero-emission solutions for heavy machinery.

Developed in-house over five years with more than £100 million invested, the 3CX Hydrogen is powered by JCB's own 55 kW Stage V hydrogen spark-ignition engine — a 4.8-litre, four-cylinder unit delivering 440 Nm of torque at 1,150 rpm. JCB says performance is identical to its diesel counterpart, and operator feedback during customer trials confirms it: "He really couldn't tell the difference."

Three composite-wrapped hydrogen tanks mounted on the cab roof hold fuel at 350 bar, sufficient for a full working day. Refuelling takes minutes via JCB's mobile refueller, developed with HYKIT — a clear advantage over battery-electric alternatives. The machine holds full EU Engine Type-Approval for Non-Road Mobile Machinery and requires no changes to service intervals or workshop procedures.

The 3CX Hydrogen also comes with a three-year operating lease through JCB Finance, including machine insurance and a full-service contract — lowering the barrier for contractors who want to cut Scope 1 emissions without committing to an outright purchase.

With over 150 hydrogen engines already built and trialled in real-world conditions across power generation, telescopic handlers, and backhoes, JCB is making its case that hydrogen combustion — not battery electrification — is the viable path to decarbonising heavy equipment.
