Dual-fuel and 100% hydrogen engines

Hydrogen combustion engines

BeHydro engines are available in both mono fuel (100% H2) and dual fuel (liquid fuel + up to 85% H2) versions. The range of hydrogen engines consists of 6- and 8-cylinder inline engines and 12- and 16-cylinder V-engines covering a power range between 1 MW and 2.6 MW.

Dual Fuel H2

The BeHydro dual-fuel engines are developed for heavy-duty applications and are very flexible in usage. Operating on 85% hydrogen gas and 15% conventional fuel, they make the owner or user less dependent on fossil fuels.

With this type of engine, CO2 emissions are reduced by up to 85%! In combination with an after-treatment system (EATS), there are also no harmful emissions. The remaining soot particles and nitrogen gases (NOx) are removed by a particulate filter and SCR system so that the latest and strictest emission standards worldwide are easily achieved.

Taking into account that these medium speed engines can run on up to 85% hydrogen AND 100% conventional fuel, they offer a solution when hydrogen is not available. Switching to conventional fuel is automatic and effortless.

With the BeHydro dual-fuel engines, we offer a state-of-the-art, user-friendly solution for companies that want to reduce their carbon footprint to an absolute minimum.

The engines have a long life thanks to an optimised air/gas mixture that causes components to heat up less quickly. They also have no problems with slight impurities in the hydrogen and do not use scarce raw materials such as lithium, zinc, cobalt, platinum, rare earths, etc.

The BeHydro dual-fuel hydrogen engines use proven technology, have been extensively tested and they are certified. They are designed to ensure long-term and efficient operation.

Mono Fuel H2

The innovative BeHydro 100% hydrogen engine range has been developed for heavy duty applications and deliver 100% clean energy. As a main drive or in combination with an alternator, they are a reliable and 100% environmentally friendly source of energy for marine, power and railway applications.

They emit no harmful emissions such as carbon (CO2), nitrogen (NOx), sulphur oxides (SOx) or soot particles. In addition, they are non-toxic and:

  • no use is made of scarce raw materials such as lithium, zinc, cobalt, platinum, rare earths, ... ;
  • avoid environmental damage caused by the extraction of scarce raw materials;
  • they do not cause any damage to human health;
  • the by-products are completely safe (the emissions consist of water vapour and aspirated air).

The BeHydro hydrogen engines are extremely versatile because they have no problem with slight impurities in the hydrogen. BeHydro engines use proven technology and are designed to ensure long term and efficient operation.

In addition to their long service life, they are also very easy to maintain. This saves costs and time for owners and operators.
