Frauenfeld’s plant converts virgin residual wood into electricity, heat, and CO₂-capturing biochar. At the Bioenergie Frauenfeld power plant, state-of-the-art wood-gas technology converts biomass into clean electricity, heat, and CO₂-binding biochar, making every piece of wood a small climate hero. To maximize efficiency of this wood-gas process even more, a cutting edge ORC-technology was integrated, capturing waste heat from the exhaust gas of four reciprocating gas-gensets to convert this to additional clean electricity and heat - ensuring that no energy goes to waste. The result is a cutting-edge, climate-positive power plant that sets a new benchmark for sustainable energy production. This project marks a bold step toward a climate-positive future and demonstrates how innovative technology can turn locally sourced biomass into a valuable resource. It proves that sustainable energy solutions can be both highly efficient and environmentally transformative.

Manufacturing status of the ORC system in Sweden/Kinnarp:

The frame of the plant, including the evaporator and preheater, has been completed and is now being fitted with the ORC module to finalize the system.

In August 2025, a high-temperature ORC system was delivered to the SENJA power plant in Norway, which will provide local district heating and electricity in the future. The plant uses part of the waste heat from the incineration of municipal and commercial waste, which is transferred via a hot water circuit at 190 °C to the ORC system.

The ORC unit with an electrical output of around 900 kW_el, converts part of this energy into climate-friendly electricity. With its successful delivery and integration, INTEC with its partners are making an important contribution to a sustainable and resource-efficient energy supply in the region.

Since the 2022/2023 energy crisis, production costs in Spain’s food industry — one of the country’s largest economic sectors — have risen significantly. In response, a large-scale government funding program was launched to promote the adoption of sustainable technologies. As part of this initiative, a major food producer commissioned our partner to supply a high-temperature ORC (Organic Rankine Cycle) system for the energy recovery from biomass waste. The high-performance system was designed and engineered by us and is currently being delivered as a modular unit. The ORC plant uses hot exhaust gases from biomass combustion to generate both electricity and process heat via a heat transfer oil circuit. The heat transfer oil is heated to 330–340 °C in a heat recovery system and transfers its heat to an organic working fluid in the ORC evaporator. This fluid evaporates at 310 °C and drives a turbine, generating an electrical output of 1.3 MW. With a turbine efficiency of around 84%, the remaining thermal energy is recovered in a second heat exchanger for industrial processes such as drying or cleaning. By combining electricity and heat production, the system achieves an overall efficiency of approximately 30% in CHP (combined heat and power) mode. The modular and automated design ensures low maintenance and high operational reliability. The use of biomass supports the decarbonization of industrial processes and exemplifies the efficient use of high-temperature waste heat from renewable sources through modern ORC technology.
