The Re² Biomass CHP generates electricity and heat according to the principle of combined heat and power (CHP). The unit consists of a wood gasifier and the combined heat and power unit (CHP). The generated electricity will either be consumed by the owner or sold into the grid. The heat generated during the process can be used for the heating of buildings, for drying grain and wood or in district heating systems.

Proven wood gasifier

The reformer is the heart of the plant. It produces wood gas from natural wood chips in a controlled process, which works on the downdraft principle: the wood chips and the wood gas moves in the same direction. With our patented and proven technology we produce an extremely clean wood gas.

Efficient wood gas CHP

The cooled wood gas passes through two filter systems, before it drives a powerful engine, which produces the electricity and heat.

Biomass CHP from Re² is built on the experience gained from over 20,000,000 operating hours. Our Biomass CHP units have proved themselves all over the world and show that sustainability and economy can be achieved simultaneously. Our vast experience and technology development as a pioneer in this field make Re² the leading manufacturer of Biomass CHP. Our company was established in 2004 as a business unit called „Renewable Energies“ of the Spanner Group. With over 100 qualified and dedicated employees in Neufahrn in Germany, we constantly progress the optimization of our pioneering energy technology and always strive towards our main goal: To make Renewable Energies competitive!

We have been producing our Biomass CHP engines which produce electricity & heat from wood chips for many years. Due to the modular system design, a power range from 9 kW to 2 MW can be achieved. See our page on cascading or repowering.

Of course, we also manufacture the appropriate conveyor technology for our Biomass CHPs, as well as efficient fuel-drying systems.
