Innovative solar: Engie launches Energiestro on frequency regulation

After Voltalia, Engie
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 …

Unlock the potential of renewable

…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…

ENERGIESTRO took part in the ”Science” category, devoted to energy storage with its ”Solar Storage Wheel” (project VOSS).  EDF received over 200 projeccts.  The process of selecting the two finalists lasted several months and culminated on March 10 2015 with the presentation of the two projects before a panel of experts at EDF headquarters.  The other finalist was the ”Reverse Electrolysis” project submitted by the German company Sunfire.  The two projects were judged by he public who voted on line between April 7 and May 3.  EDF recorded 240,000 votes.

The name of the winner was announced on June 4 during a ceremony at the ”Palais de Tokyo” in Paris, in the presence of Axelle Lemaire, Secretary of State for Internet Technology and Jean-Bernard Levy, Chairman of EDF.  Having convinced the experts VOSS has also caught public attention, since it obtained 71% of the votes, thanks to an innovative breakthrough.

By replacing traditional materials for the flywheel, (steel or carbon fiber, both too expensive, with concrete, (much cheaper) ENERGIESTRO makes it possible for the first time to store intermittent renewable energy, thus removing the last obstacle to its widespread use.
