Renewable heat
To decarbonise their heat production, companies have three solutions:
- burn biogas in their gas boilers by certifying the green origin through Guarantees of Origin,
- obtain supplies directly from a local heating network shared by various users whose production is of green origin (e.g. heat produced by a household waste incinerator),
- self-consumption of renewable heat produced on site from a biomass boiler, solar thermal energy, geothermal energy or a methanisation and biogas cogeneration system.
New heat production solutions are also being developed through green hydrogen.
Different types of renewable heat
Industrial sites consume heat for different purposes, using equipment that runs on fossil fuels. This generates significant CO2 emissions which can be reduced by switching to renewable heat solutions.
The biomass boiler
The biomass boiler uses wood, wood by-products such as bark or sawdust, company by-products or household waste as fuel. It produces steam or hot water.
Methanisation and biogas cogeneration
Cogeneration uses biomethane produced by an on-site anaerobic digestion plant (which often processes site waste and local agricultural waste). The electricity produced is usually fed into the grid to benefit from financial support mechanisms. The heat is used on site in the form of steam and hot water.

Solar thermal
Solar thermal energy uses solar collectors to transform solar radiation into usable heat, which is transported by a heat transfer fluid to meet heating or hot water production needs.
A technology widely used in southern Europe, solar thermal is only profitable in France thanks to funding from the Fonds Chaleur.
The competition with photovoltaic solar energy, which uses the same available space, is based on profitability and the priority of the site in terms of energy needs.
Geothermics
Geothermal energy is a heat production solution that uses hot groundwater and can also produce cooled water thanks to the inertia of the earth’s temperature for air conditioning installations.
