Two stage 2 Nm3/h hydrogen compressor installed into the liquid organic hydrogen carrier (LOHC) setup.

Both MH and LOHC being thermal processes, the technologies have much in common. The HYMEHC-02 is a thermal solid-state machine using temperature differences (70 °C) in cold and hot water for the hydrogen compression work. It is a compact (120 × 50 × 50 cm) and lightweight (85 kg) hydrogen compressor. It has no moving parts (apart from valve operations) offering high safety features, reducing the risk of component wear and tear.


Inlet pressure: 3 bar(a)

Output pressure: 25 bar(a)
