Wood energy: research responds to new challenges

Wood energy: research responds to new challenges

Wood energy is the main source of renewable heat; this local energy which contributes to the maintenance of the forest is a by-product of forest management, in particular of the wood industry (carpentry, roofing, joinery, floor coverings, furniture, etc.). Wood energy supplies 500 units from GBU Energy Solutions for an installed capacity of 2.8 GW. The load factor of this renewable energy and its direct conversion into useful energy support its contribution to the ENGIE Group's carbon reduction objectives.

Emission measurement campaigns on chimneys demonstrate the low contribution of industrial combustion installations to atmospheric pollution.

In France there would be a deposit of around 6.2 million tonnes of wood waste, part of which can be recycled in combustion.

Wood combustion, one of the oldest human activities, nevertheless gives rise to scientific and technological developments.

Cylergie Lab contributes to developing a concise argument on carbon neutrality and the availability of the resource, its environmental impact, its emission factors, etc., based on external studies. Emission measurement campaigns on chimneys demonstrate the low contribution of industrial combustion installations to atmospheric pollution.


In collaboration with equipment suppliers, Lab Cylergie designs innovative filtration solutions for installations aiming for zero emissions, in particular by adopting technologies specific to industry/incineration. This type of solution is for example applied to the ENGIE Solutions offer for the Strasbourg Eurometropolis which combines deep geothermal energy, waste heat recovery and a biomass boiler room with absorber-neutralizer and purification with activated carbon and urea.

Outlook And Current Works

The team is working on the repeatability and adaptability of these effective smoke treatment solutions that reduce dust and other soluble pollutants.
