EX-4250D

The Plug EX-4250D is a PEM electrolyzer presented as the building block for high-volume hydrogen production solutions. The datasheet declares an output of 2000 Nm3/h (4250 kg/day) of hydrogen at up to 99.999% purity and 40 barg without a compressor, and an average stack efficiency of 49.9 kWh/kg. Start-up takes 30 seconds warm and under 5 minutes cold, load following is instantaneous, and the installed footprint is 117.2 m2. Water consumption is 13 liters per kg of hydrogen produced. Note on the power rating: the datasheet gives stack power consumption as "up to 10 MW" for an operation range covering sub-MW to 10 MW, so the 10 MW recorded here is the top of that range, not a rating for the 4250 kg/day unit.
