Hy.GEN-e HYDROGEN GENERATORS
HyGear offers hydrogen supply ranging from 10 Nm3/h up to 1000 Nm3/h. We apply both technologies of steam methane reforming and electrolysis. Our steam methane reformers offer the most energy efficient and cost-effective supply of hydrogen. Our electrolysers offer zero emission hydrogen supply and are especially suited for applications where electricity is affordable or zero emission is mandatory or desired.
The Hy.GEN-e systems produce hydrogen through PEM (Proton Exchange Membrane) electrolysis technology. PEM electrolysis is considered a promising technique for high purity and efficient hydrogen production. As technology offers an advantage with a compact design and the system can operate at higher current densities, contributing to a reduced carbon footprint. In addition to PEM electrolysis HyGear also offers alkaline electrolysis technology.
The system uses Temperature Swing Adsorption (TSA) technology with the ability to operate under the pressure of 15 bar(g) without the use of any compressor. This is more energy and cost-efficient when compared to traditional gas separation systems.

TECHNOLOGY
Pre-treated water is fed into the lye tank in which the lye is prepared and sent to the electrolyser. In the electrolyser, water is split into hydrogen and oxygen gas using electric energy. Hydrogen gas is evolved at the cathode side of a cell and exits through perforations at the cathode side separator plate towards the hydrogen manifold channels. The reaction involved at the cathode:
2H2O + 2e– -> H2 + 2OH–.
At the same time, oxygen gas is evolved at the anode side of the cells. The reaction involved at the anode:
2OH– -> H2O + 1/2 O2 + 2e–.
Hydrogen and oxygen gas then enters the hydrogen separator and oxygen separator respectively, where the lye is separated from the gases and recycled back into the electrolyser via the lye pump. The hydrogen gas is then fed to the Temperature Swing Adsorption (TSA) unit for further purification while oxygen is vented out as a by-product or can be upgraded and used if required.
