High efficiency cogeneration facilities

A cogeneration unit COGEGRID® consists of the following main elements:

  • A biomass gasifier transforming solid biomass into a fuel gas, syngas, with a high conversion efficiency.
  • A syngas purification equipment that eliminates unwanted constituents (dust, tars, chlorine,…)
  • An internal combustion engine that generates electricity and heat recovery from fumes and the cooling system.

The COGEGRID® unit has a high electrical efficiency thanks to the motor technology used and a high energy integration. Thus, electricity production alone can make this type of installation profitable. Potential applications include on-site or district heat cogeneration, as well as the electrical production alone, connected or not to the network.

Usable resources include different types of biomass:
  • Forest wood
  • Pruning wood
  • Agricultural by-products
  • Waste from the wood industry
  • Recycling wood,…



Advantages of the COGEGRID® solution:

  • High electrical efficiency
  • No exhaust gas treatment (with clean wood)
  • Proven syngas purification technology
  • Fully automated operation
  • Reliability and robustness
  • Economic profitability
