Our history

Lemon Energy was born from the idea that the least polluting energy is the one we don't consume. With their dual experience in industry and the energy sector, founder Grégory Choppinet and his partner Paul Dède have taken up the challenge of decarbonizing the industrial sector.

Believing that an optimal solution cannot be achieved by addressing problems individually, Lemon Energy combines expertise in thermodynamics, electricity and digital technology to optimize an industrial site as a whole. We advocate a pragmatic, hands-on approach that focuses on measurable results over time, rather than long-term theoretical commitments.


Born in the incubator of CentraleSupelec, a member of FrenchTech Paris-Saclay, Lemon Energy develops innovative solutions for industrial performance.

We use Industry 4.0 technologies to improve energy efficiency, up to predictive analytics for energy consumption in industrial processes. Our research projects are recognized by the French Ministry of Higher Education, Research and Innovation.



Lemon Energy provides highly competent services and innovations to continuously adapt to industry needs while maintaining its independence.
