At the heart of the new version of the hydrogen MC250.09FL is the FCH 96V module, a fuel cell system using PEFC (Polymer Electrolyte Fuel Cell) technology, combined with a 6kg hydrogen tank capable of delivering constant power through a 30kWh lithium ‘buffer battery’ with a complete servo system, including humidifier, air exchanger, control electronics and relevant safety devices.
The battery is said to last at least between two and three hours of normal use, with the fuel cell automatically kicking in to top up or maintain the battery pack. With constant use the combined package allows the machine to run for five to six hours before refuelling.
Refilling the cylinder from a standard 450 bar recharge point with an OMB Saleri nozzle takes around five minutes, or the tank can be simply swapped for a full one. Recharging the lithium battery is said to take around about 90 minutes with the high powered onboard charger.
The layout of the hydrogen model is very similar to the standard battery powered machine with an identical specification in terms of overall weight, dimensions and mechanical/electrical connections. The benefit if this is that the hydrogen module can be interchanged with the standard machines 96 volt, 1,050 Ah lead acid battery pack. The work required to switch to the fuel cell configuration is limited to the repositioning of the electrical cables and the addition of a simple can-bus wiring harness, which will be fitted to all standard models from the start of next year.

Chief executive Maurizio Manzini said: “This new technology marks a milestone for JMG, confirming our pioneering vision in the energy transition of industrial lifting by introducing a flexible, scalable energy system suitable for intensive work cycles. While it was a symbolic and technical debut - the first units should be ready to ship in the new year and represents the first concrete step of a new R&D path.”
