CO2 driving decarbonization
Deeptech & greentech startup
Cixten is developing a modular thermal machine that recycles waste heat starting from 60°C.
Our technology allows produces electricity or compressed air by using waste heat as its source.
In co-generation mode, part of unconverted residual heat can be recovered in a heat network.
// ACT for energy efficiency
Industrial thermal effluents represent a colossal waste of energy. Efficiently utilizing this waste energy is a crucial step towards achieving carbon neutrality.
Cixten is fully committed and involved in helping to meet current challenges:
Reduction of the carbon impact of processes
Improved business competitiveness
Strenthening energy independence
Energy recovery according to a circular scheme
A wide range of applications
// INNOVATE to bring new solutions
Our technology, protected by two patents, is based on the advantageous use of the exceptional thermophysical properties of supercritical CO2 .
The specific cellular structure and design of our machine makes this groundbreaking innovation possible, ensuring very efficient heat transfers with low thermal amplitudes. The useful energy is generated via controlled thermodynamic cycle exploiting the CO2 under pressure in a closed circuit.
