Schniewindt heaters or steam generators are part of the first large-scale plant for the production of e-fuels


The world’s first large-scale plant for the production of synthetic, virtually climate-neutral fuel, or e-fuel for short, is being built in Chilean Patagonia.
This location was chosen because of the optimal climatic conditions for wind energy in southern Chile, which will be the sole source of power for the plant. The project, named “Haru Oni,” is in the hands of Siemens Energy in cooperation with the sports car manufacturer Porsche, and has received around eight million euros in funding from the German Federal Ministry for Economic Affairs and Energy.
The pilot plant is expected to produce 130,000 liters of e-fuel as early as this year. By 2024, the volume is to increase to 55 million liters, and in 2026, production of 550 million liters is planned. Porsche CEO Oliver Blume sees key advantages in the ease of use: “E-fuels can be used in internal combustion engines and plug-in hybrids and make use of the existing filling station network.” (Quote:

So what is the function of Schniewindt steam generators in this project?
Schniewindt engineers have designed a complex evaporator system for the manufacturing process, including a corresponding control system. In addition to the steam generator designed for 850 kW and the appropriate control systems, Schniewindt supplies more components, which are installed in two containers with overall dimensions of around 6 x 5 x 3 meters. In this plant, a complex process takes place for filtering and further pre- and treatment of CO2. Dr. Sarah Schniewindt thanked all her employees for the great performance: “We are all pleased to use our know-how to create technical possibilities that can help to reduce CO2 emissions worldwide and thus advance the energy transition.”
