Speeding innovation for industry
Article | Energy storage
By effectively “disconnecting” supply from demand, energy storage will play a crucial role in tomorrow’s grids. CEA Tech is developing a variety of technologies—from battery-based and thermal storage to hydrogen systems—to respond to a range of needs, regulatory and budgetary requirements, and environmental concerns. Stationary storage is emerging as a crucial factor in driving the growth of intermittent renewable energy. One of the biggest challenges facing energy storage is finding a viable business model, one that will require lower costs and enable the delivery of additional services.
CEA Tech is also focusing on storage technologies for mobile applications like vehicle batteries and telephones. These technologies include micro fuel cells and micro-batteries.
Researchers at Liten, a CEA Tech institute, set out to determine whether or not micro cogeneration affects fuel-cell aging. The first long-duration tests conducted under the Propice project provided some answers.
The REACSOL solar reactor developed by Liten, a CEA Tech institute, was successfully used for high-temperature biomass gasification in tests carried out in conjunction with lab CNRS-PROMES. The results of the tests—gasification of wood-based biomass continuously fed into the reactor with concentrated solar energy as the heat source—were encouraging.
Leti and Liten, both CEA Tech institutes, developed the electronics and algorithms required to measure the internal temperature of a battery cell by estimating electrical impedance. The purpose of the solution is to detect the early signs of thermal runaway in embedded lithium-ion batteries.
Liten, a CEA Tech institute, recently joined forces with France’s energy agency ADEME to assess the benefits combining electricity storage and renewable energy production could bring to micro-grids connected to the main grid on the island of Corsica.
Silicon electrodes are among the frontrunners in the race to replace the graphite electrodes currently used in Lithium batteries. Several imaging and spectroscopy techniques have provided a deeper understanding of the mechanisms that underpin silicon electrode degradation.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
