Companies all over the world are facing major challenges: To meet climate targets while reducing price risks, they must fundamentally transform their energy supply – away from fossil fuels and toward renewable energies.
A climate-friendly and at the same time highly economical solution is provided by combined heat and power plants (CHP) that are operated with wood-based biomass – e.g. with wood pellets, wood chips or wood briquettes (in short: wood-fired power generation).
By combining electricity and heat generation, such biomass CHP units achieve higher efficiency than many other energy technologies. Operators therefore not only save CO2, but also cash. In addition, biomass is the only renewable energy source that can provide energy all year round, regardless of the weather or time of day.

A biomass cogeneration plant for wood-fired power generation is not only highly efficient in terms of economy and ecology, but also offers a wide range of possible applications.
- Wood chips drying
- Drying or heating purposes in the production process
- Generation of cooling energy via absorption chillers for cold storage, air conditioning, etc.
- Conversion of waste heat into electricity (e.g. ORC)
Companies that use a biomass cogeneration plant to generate electricity from wood and thus contribute to climate protection receive financial support at many levels in Germany. In addition to the feed-in tariff for surplus electrical energy, the German Federal Ministry of Economics and Export Control (BAFA) promotes corresponding projects, often in the areas of process heat or energy efficiency.
The Kreditanstalt für Wiederaufbau (KfW) also supports climate-friendly rethinking with promotional loans and repayment subsidies of up to 55 percent of the eligible costs. And the individual federal states and regions also reward the use of biomass CHP units as progressive and environmentally friendly energy generation.
