A French start-up has developed a concrete flywheel to store solar energy in an innovative way. Currently being tested in France, the storage solution will be initially offered in France’s overseas territories and Africa…
This storage project will be hosted in the Thémis experimental center in the Pyrénées-Orientales and will be based on Energiestro’s flywheels. Which will find its second order there, for equipment that remains to be sized but will probably be close to the 10 kW / 10 KWh soon supplied to Voltalia for Guyana and probably installed this year. “We will thus move on to prototypes …
Important step in the development of Energiestro, we made our first 10 kWh flywheel made of prestressed concrete at the end of 2018.
Energiestro is one of the 5 startups chosen by Shell France in 2018 for its liveWiRE program supporting the development of startup companies in the fields of energy and mobility.
…Batteries are mainly used for short-term storage needs (less than 24 or 48 hours) and are very versatile. Indeed, hydrogen does not appear to be the ideal competitor, as it is more likely to be used for mass storage or other applications such as mobility. For stationary storage, the battery has a discreet but particularly formidable competitor: the flywheel…

Energiestro, making the world more renewable through storage
Energiestro is developing a technique for storing renewable energies using flywheels
that are 10 times cheaper than typical existing models since they are made of concrete.
Energiestro’s goal is to enable the development of renewable energies by offering
massive storage at very low cost.
From May 24th to 26th, Energiestro will be at Viva Technology in Paris
at the ENGIE Lab stand.
Co-founder André Gennesseaux talked to us about his project,
his perspective on the future of energy and the links between his startup and ENGIE…
