E-fuel plant engineering
Fuel from sunlight, air and water
The plant
Our plant concept combines concentrated solar heat, CO₂ captured from the air and green hydrogen into one continuous process chain for synthetic kerosene (Jet A-1). We develop the core components ourselves.

Components
We do not buy the key assemblies as off-the-shelf products. We design them ourselves, model them in our own CAD model and take them through to manufacturing planning. This way the components fit together precisely, and the know-how stays in the company.
10,000 lenses of around one square metre each concentrate sunlight like a magnifying glass. They are motor-driven to track the sun and are mounted on a steel structure with around four metres of clearance – the land underneath remains available for agriculture.
At the focal point of each lens, a mirror directs the light into an internally mirrored tube beneath the lens row. Through these light channels the light travels to the storage – without solar cells and without heat-transfer fluid in the field. In the light collection bridge, the 100 light tubes are bundled via deflection mirrors and led through glass windows into the storage.
A 24 × 40 × 10 metre structure stores solar heat at very high temperatures in rock or sand. A steam generator turns it into steam and hot water for the processes – at night and on overcast days as well.
Fans draw ambient air through a sorbent that binds CO₂. Heat from our own storage releases the CO₂ again – so solar heat is used directly to obtain the feedstock.
Placeholder: Our electrolyser produces the green hydrogen for synthesis from water. We develop the design, the stack concept and its integration into the plant’s heat and material cycle ourselves. Technical data to follow.
In the main reactor, CO₂ and hydrogen are converted directly into hydrocarbons over an iron catalyst (CO₂-based Fischer-Tropsch). A second reactor extends the molecules into the kerosene range, and the column separates the finished Jet A-1.
Our own know-how
Every component is backed by a continuous engineering chain that we built ourselves: requirements are traced across three layers, every change becomes visible down to the affected assemblies, and design ends in standard-compliant manufacturing data according to ISO 10303.
