Pour gérer l'intermittence des énergies éoliennes et solaires, sans recourir à des backups fossiles, il faut stocker l'énergie, mais les technologies conventionnelles sont très couteuses. Christophe Stevens propose deux solutions relativement simples permettant de réduire fortement le coût du stockage d'énergie, démonstration et chiffres à l'appui. talk : "How to divide by ten the cost of energy storage"

After working 12 years at Michelin in the field of cost rationalization, Christophe Stevens decided to tackle the cost of energy storage, the main obstacle to the massive development of renewable energies. He invented and patented several processes to store energy for a cost ten times lower than batteries. These solutions can be implemented by assembling already existing components, which makes it possible to envisage a rapid industrial development and to easily demonstrate economic assumptions difficult to believe. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
