With the short-term depletion of fossil fuels (oil, natural gas, coal, etc...) and the deterioration of our environment looming, the use of renewable power sources is becoming essential. The energy transition has thus become one of the major technological and scientific challenges of the 21st century, with non-carbon renewable power sources representing a major alternative to fossil fuels. However, their exceptional potential is strongly offset by the storage problems caused by the intermittent nature of their production. Storing this energy remains an essential step. CNRS researchers are at the heart of the development of these storage systems, a real technological challenge. Some of them elaborate on their research, its potential and limitations.
