Reversepowerplant for the Ilg energy plant in Vorarlberg

In Dornbirn-Hatlerdorf, the first Reversepowerplant was realized that SYNCRAFT implemented as general contractor. Due to the immediate proximity to a residential area, particularly high requirements had to be met in terms of noise technology. The plant originally started with an electrical output of 180 kW and was optimized in close cooperation with the customer - including the use of a larger CHP unit. Today, it delivers up to 270 kW of electrical power and, with around 83,000 operating hours (as of 09/2025), is one of the most experienced backwards power plants in the SYNCRAFT portfolio.

Green Carbon

The green carbon that is produced stores 30 percent of the original CO₂ that was contained in the wood. It is used in metallurgy and innovative building materials, among other things. In a carbon-preserving application, a long-term CO₂ sink is created. Reversepowerplants are therefore not only climate-neutral, but also actively remove CO₂ from the atmosphere by producing green carbon.
