WHAT WE BUILD
Reliable solutions that pair industrial performance with lower impact.
We develop and design innovative, reliable solutions that combine industrial performance with reduced environmental impact. Thanks to our patented plasma solutions, we offer industries decarbonisation alternatives — for the production of clean hydrogen and carbon products, and for the supply of clean heat at very high temperatures for a wide range of industrial applications.
VALUES AND MISSIONS
Decarbonise industry. Build a more sustainable world.
Vision
Industry accounts for almost a quarter of global greenhouse gas emissions. Our vision is to help hard-to-reduce sectors achieve their net-zero ambitions with innovative solutions tailored to diverse industrial applications — concrete answers to the climate targets for 2030, 2040 and 2050.
Mission
We integrate our advanced solutions as clean, sustainable alternatives into industrial value chains, and support players in the energy and heavy-industry sectors in their ecological transition with cutting-edge technologies that reduce their environmental footprint.
Culture
Research and innovation are at the heart of our business, and efficiency, sustainability and accessibility are at the heart of our products. We value the well-being of our employees, in an atmosphere of respect and trust where everyone is encouraged to take initiative and flourish.

Since 2018
A continuously growing French deep-tech company developing industrial plasma technologies for the energy transition.

Research & development
Three-phase plasma designed for continuous, industrial-scale operation. R&D is the core of the company.

Technological firsts
- First commercial three-phase AC plasma torch
- Plasma torch designed for high-pressure operation
- Continuous arc operation for industrial processes
Sophia-Antipolis, France
Designed, built and run under one roof.
The torches, the reactor and the control system are engineered by the same team that operates the pilot every day.

Our expertise
Every discipline a plasma plant needs, in one team.
The same team designs the torch, the reactor, the control system and the software, then runs them on our pilot.
Plasma physics & chemistry
Arc physics and plasma chemistry, from the electrodes to the carbon the reactor produces.
Three-phase AC power
Torches that run directly on grid power at 50 Hz, with no AC/DC rectifier.
Process engineering & CFD
CFD and thermodynamic simulation, feedstock and flows, heat transfer, product separation.
Mechanical design
Equipment for extreme conditions: ASME and CODAP design, finite-element validation.
Automation & control
Industrial PLCs and HMIs, Modbus TCP/IP, OPC UA, EtherCAT and Profinet, factory-tested cabinets.
Data & machine learning
PlaSight: the arc camera, electrode tracking and live process data, on screen and on the phone.
Milestones
From incorporation in 2018 to three continents.
Each step built on the last: the torch first, then the unit around it, then scale.
