HyGear offers small scale and compact hydrogen (H2) generation systems applying the high-yield steam methane reforming (SMR) technology. These Hy.GEN® systems range from ‘compact’ to ‘grand’ model and generate hydrogen and biohydrogen at the end user’s site. On-site hydrogen supply by the Hy.GEN® increases the reliability of supply and decreases the costs. The Hy.GEN® systems of HyGear are also able to produce biohydrogen from renewable natural gas (RNG) or biomethane. Combined with carbon capture this results in carbon-negative hydrogen production.


A reliable supply of process gases plays a vital role in most industries. Currently, these gases are mainly supplied by electrolysis or road transportation of compressed or liquefied gas. HyGear offers small scale on-site hydrogen and biohydrogen generation systems ranging from 10 Nm3/h up to 1000 Nm3/h based on steam methane reforming technology. This makes them highly suitable to be installed at industrial sites and hydrogen filling stations.

The Hy.GEN® systems produce hydrogen by converting natural gas with steam methane reforming. Decentralised hydrogen and biohydrogen production offers a safer, more reliable, and cost-effective alternative to conventional hydrogen supply by tube trailers or electrolysers and significantly lowers the environmental impact.

In the Hy.GEN® of HyGear, steam methane reforming technology is applied. A high-yield techology for the production of hydrogen and biohydrogen.

The steam (H2O) produced from waste heat is added to the desulphurised gas and led into the reformer. The heat and catalytic properties of the reformer cause the following reaction:
CH4 + H2O -> 3H2 + CO.

The remaining carbon monoxide is then converted in the water gas shift (WGS) assembly to produce more hydrogen:
CO + H2O -> CO2 + H2.

The gases then enter the Pressure Swing Adsorption (PSA) where the hydrogen is separated from other gaseous species under elevated pressure using differences in adsorption properties.

The cleaned hydrogen is the stored in the buffer vessel and can be used as an industrial gas or energy source.
