How would you describe your solution in a few words?

The patented and highly efficient process of SaveEnergy flue gas condensation increases the heat efficiency of wood-fired heating and power plants by 15-50%. The heat from the flue gas is extracted via injected process water. The sum of all water droplet surfaces forms the heat exchanger. This results in a heat exchanger surface the size of several football fields. The water droplets are constantly rebuilding themselves. The SaveEnergy heat exchanger (water droplet) can neither get dirty nor corrode. This leads to low-maintenance and robust operation and sets the highest standards in terms of availability and durability.

Who are your customers?

SaveEnergy’s customers are operators of wood-fired heating and power plants. They range from the wood-processing industry to energy companies, municipal plants and private operators.


What are the environmental benefits of your solution?

The SaveEnergy-flue gas condenser increases the thermal efficiency of wood-fired heating (power) plants by 15-50%. This enables the maximum energetic yield of the regional, renewable, but finite energy resource wood. Especially in markets such as Switzerland, which make intensive use of the available energy wood resources, increasing the heat production of wood-fired heating (power) plants by 15-50% is crucial for achieving climate targets.

How do you manage to exist on the market?

SaveEnergy’s global success is based on the innovative and patinated process for heat recovery in exhaust gas. Based on the process, robust and highly efficient products have been developed. SaveEnergy moves close to the market and continuously develops the processes and products. In this way, SaveEnergy meets today’s and tomorrow’s challenges in energy production from wood.
