Hyliko, “carbon-negative” hydrogen for mobility

Design of an integrated hydrogen production and distribution station using biomass

Hyliko awarded Artelia a preliminary design contract for an integrated site including hydrogen production by biomass thermolysis and a distribution facility for different types of vehicle (from 360 kg to 720 kg H2/day).

Thanks to the innovative process used to produce the hydrogen, this operator in the decarbonisation of mobility aims to offer a solution with a negative carbon footprint.


Hydrogen is now seen as one of the ways of decarbonising mobility, particularly heavy mobility, provided that processes can be developed to produce this gas on a large scale with low carbon emissions. Hyliko operates a biomass thermolysis process (Haffner Energy) that produces pure hydrogen at a competitive price, while containing the carbon from the transformation process in a biochar that can be used as a fertiliser. By using local biomass from vegetable waste and this biochar as a carbon store, Hyliko can offer a virtuous “carbon-negative” model for mobility.

The concept is to combine hydrogen production and a fuel distribution system on the same site. With wide experience in the distribution of alternative fuels, Artelia studied the integration of the production units and the sizing of the hydrogen storage and distribution units. Our teams also helped Hyliko to define the size of its stations and identify future sites. The main challenge was to meet the production/distribution objectives while managing the technical and regulatory constraints associated with hydrogen and its storage.
