2008 : The origins

The basic idea was to make an energetically self-sufficient house thanks to an externally heated valve engine. Wood generates heat, which in turn generates electricity. For sure, this is a real challenge and a technological feat.

However, some research highlighted one observation: the industry stands as a promising area. The figures are blatant: the French industrial sector accounts 51 TWh of wasted heat (fatal heat), which is the equivalent of 6 nuclear reactors’ electricity production.

"We create added value from industrial waste; these are opportunities’ tank.” (Brice Bryon)

2015 : Energine's birth

On October 14th, after seven years of hard work, the Ministries of Economy, Labour and the SYNTEC Federation awarded the National Engineering Award. Assystem's engineers, in partnership with the FEMTO-ST Institute, were rewarded for their innovative spirits and determination for the Energine creation. This new technology perfectly embeds the energy mix by directly influencing energy production and consumption.

2017 : Ananké unveiled

On September 22nd, Brice Bryon, Thibaut Cartigny, Pierre Ranc and Mathieu Doubs founded Ananké. The main objective is to give industrialists the opportunity to include the energy transition in their strategies while boosting the innovation/competitiveness combination. How? Thanks to an innovative thermomechanical conversion process.

The Externally Heated Valve Engine (EHVE) developed by Ananké is used for cogeneration. This technology makes it possible to convert wasted heat - known as "fatal heat" - into a useful source of energy.

Several entities have supported the company in Nord Franche-Comté such as Femto-ST, Vallée de l'Energie, ADN-FC, Ademe, BPI France, Aire Urbaine Investissement, Communauté de l'Agglomération Belfortaine, BGE Franche-Comté, Assystem, Burgundy Franche-Comté University and Réseau Entreprendre.

Our motto

One of the major goals the start-up seek is to tie industry up to ecology for social progress and competitiveness.


"Faced with its limits, the exploitation of fossil fuels leads to major environmental and energy crises. In order to prevent an unprecedented cataclysm, our actions call for a necessary environmentally-wise evolution. The energy transition implies structural changes and yields a global challenge that everyone has the opportunity to be a part of.

When it comes to big data, we stand then as a key stakeholder in this industrial revolution that upholds the emergence of intelligent energy networks. Since we are at the heart of an increasingly diversified energy mix, we have the power to harness the resources within our reach, thus going beyond our simple consumers status.

Given this crucial challenge, public and private entities are expected to gather their forces to support democratised energy efficiency. To make this possible, the industry is one of the strategic gateways: the adoption of suitable practices and the innovative solutions deployment are two essential keys when dealing with energy transition, which embody a great source of opportunities to seize and provoke rather than a fatality."
