About

We are looking for investors in our start up in seed. Let’s discuss

NEEXT Engineering optimises future energy systems.

Through agile engineering and its reactive fluids technology, it maximises efficiency of Heat to Power and Power to Heat applications and accelerates the decarbonisation of industry.

Developed in collaboration with the CNRS LRGP (Laboratoire Réactions et Génie des Procédés), reactive fluids technology is based on compounds capable of initiating reversible and controlled exothermic and endothermic reactions in a closed loop within energy infrastructures.

These additional heat recovery and release processes improve conversion performance by over 30% for most of Heat to Power and Power to Heat applications (e.g. Nuclear, Biomass, Concentrated Solar Power, Geothermal, Waste heat recovery, Heat Pump), while supporting the energy transition and industrial decarbonisation.

This innovation already benefits from significant EU and French public financial support.
