Hydrogen generator

Hydrogen generators for various applications

Metacon offers hydrogen generators (HHG systems) suitable for both small and large plants, tailored for traditional biogas producers, wastewater treatment plants, and marine applications. Our generators have a production capacity of 50 to 250 cubic meters of hydrogen per hour, using proprietary technology to achieve purity levels between 99.9 and 99.999 percent, customizable to your needs. Our hydrogen generators are designed to work with various fuels such as natural gas, LPG, biogas, and ammonia. They offer reliable, quiet, and efficient hydrogen production.

Natural gas can be sourced from the existing network, while biogas can be extracted from biogas plants, wastewater treatment plants, landfills, or organic industrial and household waste. Hydrogen derived from biogas or upgraded biogas (bio-methane) is sustainable as its production relies on renewable fuels. Ammonia, a widely available carbon-free fuel, can also be used to produce green hydrogen efficiently from renewable ammonia.

High-purity hydrogen production, suitable for automotive refueling stations, hydration plants, glass and electronics industries, and PEM fuel cells, among others


Our hydrogen generator is innovative and compact – 40 times smaller than traditional reforming designs, making it significantly smaller than traditional reforming plants and easier to integrate into different environments.


Our hydrogen generator offers increased security and safety by eliminating the need for open flames.


With low operating temperatures, material costs are reduced and enable near-total elimination of emissions such as nitrogen oxide, carbon monoxide and sulphur oxide.


With our patented HIWAR reactor design, our hydrogen generator can achieve up to 8 percent higher efficiency than conventional technology.


In our proprietary and patented reforming process, hydrogen is produced through a technology that uses unique catalytic surfaces in a high-efficiency reactor. By blending the fuel with steam and using an advanced reactor, we can initiate a chemical process where the fuel is converted into hydrogen, carbon monoxide, and carbon dioxide. This conversion occurs by supplying heat to the steam/fuel mixture through via catalytic oxidation. Each reaction takes place on thin layers of catalysts, enabling very high efficiency. Later in the process, the amount of carbon monoxide can be reduced, and as an option, carbon dioxide can be captured and stored by coupling our system with a carbon capture and storage (CCS) system to significantly reduce carbon dioxide emissions.

  1. To initiate the reforming process, fuel is required – such as hydrocarbons like biogas or natural gas along with a sufficient supply of water (steam).
  2. When a fuel and steam mixture is reformed according to the process, involving thin film catalytic surfaces in a highly efficient reactor, results in the production of hydrogen, carbon monoxide, and carbon dioxide.
  3. In order to effectively start the reforming process, both air and fuel such as biogas or natural gas are heated up, before catalytic oxidation (combustion).
  4. The air and fuel mixture are combusted and converts to water and carbon dioxide for heat generation. The process is safer than conventional reforming processes as it does not rely on open flames. This results in reduced carbon dioxide emissions from the process, increased system efficiency and reduced size of the plant.
  5. The result of our process contains hydrogen and carbon oxides. Carbon monoxide is minimized, and the resulting mixture is then added to a Pressure Swing Adsorption (PSA) system for purification. The PSA process enables us to produce pure hydrogen, with a range from 99.9% to 99.999%. The system can be coupled (option) with a carbon capture and storage (CCS) system to significantly reduce carbon dioxide emissions.
