SYNOCA® = SYngaz NO CArbon


SYNOCA® is an industrial solution allowing the production of a rich renewable gas (hypergas®) (around 10 MJ/kg) from a wide range of residual biomass or organic waste. The process is based on thermolysis with almost no dependence on electricity.

This game-changing technology, which is protected by 15 families of patents, primarily targets industrial installations for the production of thermal energy with a power ranging from 5 MW to more than 20 MW.
The decisive advantage of the SYNOCA® solution for its clients is to achieve a competitive cost price compared to natural gas, while allowing massive decarbonization.

The solution, through the co-production of biochar, is strongly carbon-negative. Biochar, a recognized agricultural amendment made up of more than 85% carbon, allows the sequestration of approximately 135 kg of CO2 per MWh of gas. Thus, by combining the avoided carbon and the sequestered (or captured) carbon, the total reduction in CO2 emissions amounts to 466 kg per MWh.

A 10 MW installation (LHV) operating at its nominal power 8,000 hours per year will avoid 37,000 tons of CO2 per year, including 19,000 tons sequestered (or removed from the atmosphere).

The richness of the gas makes it possible to reach an adiabatic flame temperature close to 2000°C, which makes the gas compatible with the vast majority of industrial applications.
The installations of industrial customers are not modified, to the exception of the burners. These can be versatile so as to authorize combustion with syngas or natural gas.

Most projects, as long as the biomass used is not recycled, will be able to benefit from simplified regulations which greatly simplifies permitting procedures.
The thermolysis process, which is entirely allothermic, is distinguished from pyrolysis, which is autothermic, by the complete absence of introduction of air or oxygen into the gas.

Thanks to the use of biomass, abundant and inexpensive, it is also a scarce technology capable of completely relocating the value chain, from the harvest of the incoming resource to the end user, thus linking ecological transition and valorization of territories.

For what uses?

In Europe, more than 14,000 sites consume fossil natural gas for their industrial thermal process needs (metal, glass and ceramics, textile, paper and pulp, food processing, bricks and tiles and petrochemical industries) or to supply district heating networks and cogenerate green electricity on demand. Most of these sites face severe technical and economic constraints that are hindering their decarbonation.

The SYNOCA® modules enable connected sites to meet their decarbonation targets and to secure their gas supply, by replacing the purchase of natural gas with autonomous production of renewable gas from locally sourced biomass. Industrial customers will see a significant reduction in the volatility of their energy costs.

Biomass supply contracts are generally negotiated over multi-year periods, ensuring stable primary energy. fluctuations.

Syngas, Hypergas®, what is the difference?

Syngas (or synthetic gas) is a gaseous mixture that does not exist in its natural state, but is "synthesized" by a chemical reaction.
Syngas consists mainly of hydrogen (H2), carbon monoxide (CO), methane (CH4), water (H2O) and carbon dioxide (CO2). Other impurities are also present. It is 2 to 3 times less energetically dense than natural gas.

Syngas can be produced from fossil or renewable sources.

  • Production from fossil fuels:
    o Coal gasification
    o Steam reforming of natural gas
  • Production from renewable fuels:
    o Pyrolysis/thermolysis of biomass
    o Waste gasification

Hypergas® is a hydrogen-rich syngas (>45%vol), created from the thermolysis of biomass using a process developed by Haffner Energy.
The advantage of hypergas® over other syngas is its low level of impurities.

It is an interesting alternative for substituting natural gas in fuel applications (furnace, boiler, heat treatment, etc.) or as a precursor (Fischer-Tropsch, for example).
