A pilot project involving the production of renewable hydrogen via the electrolysis of water. This pioneering project has recently been categorised as R&D.

After completing rigorous pre-commissioning tests, we have commenced the production of renewable hydrogen using water and electricity generated from a 110kWp solar self-consumption system.

The renewable hydrogen that is produced will have two uses:

We will store some of it at 35barg pressure to be compressed through a piston compressor from 35barg to 500barg. The compressed hydrogen will be stored in high-pressure cylinders for fuelling a 5-tonne warehouse forklift truck. A fuel cell powered forklift truck driven by an electric motor.

In parallel, when the high-pressure storage tank is completely full and the forklift does not need to be refuelled with H2, we will use the stored hydrogen to run the electrolyser’s inverter process. We will run it through a PEM technology fuel cell which, in combination with O2, will generate electricity. And this electricity will be consumed by the headquarters as if it were an energy storage system, or as a UPS providing an auxiliary service.
