CARBON will unveil a demonstrator panel at Intersolar in Munich in a few days.
The latest modeling tools, which are both powerful and yet efficient in terms of computational resources, can now be used to simulate the fast charging of an 18650 cell, by characterizing current and temperature heterogeneity, stoichiometry of electrode materials, and location of lithium plating, etc. This marks a major step forward in developing safer, more efficient and durable batteries.
3SUN and the CEA have carried out their first outdoor ageing campaign on silicon perovskite tandem cells.
What if there were solar panels tomorrow that could produce hydrogen directly from sunlight? With this possibility in mind, several laboratories at CEA-Liten, and most notably at the INES (French National Solar Institute), are currently developing a photo-electrolyser prototype and a test bench.
Over time, this innovation could completely eliminate the need for transformers operating at 50 Hz, as photovoltaic sources and other renewable energies could be connected directly to the distribution network via this innovative power electronics.
A pioneer in this field, the CEA at INES has combined various innovations in metallisation and interconnection to reduce Ag consumption to 14mg/Wp while maintaining performance and reliability.
Are you a Master 2 student in your final year of engineering school? Do you dream of contributing to the energy transition and the decarbonization of our systems? CEA-Liten, a laboratory of excellence dedicated to new energies and technological innovation, is offering you this unique opportunity!
As part of some thesis work on the propagation of thermal runaway, a CEA-Liten team found that this very phenomenon occurs in certain all-solid-state cells, despite them being regarded as safer. This research also identified the key factors contributing to this process.
As part of the EU-funded project Best4Hy, CEA-Liten synthesized platinum-carbon catalysts derived from recycled platinum salts before integrating them into the core of fuel cells (MEAs), in order to test them in designs representing industrial-scale fuel cell stacks. As it turns out, their performance is similar to that of the benchmark MEAs for this project.
The local electrochemical behavior of a lithium-ion battery cell is altered by sensors placed inside the cell according to research by CEA-Liten, CEA-Irig, and four other partners*. The results, published in Nature Communications, could help battery manufacturers improve their products.
CEA-Liten develops lightweight composite photovoltaic panels for various applications, including solar mobility. Their laboratories, on the INES site, have equipped themselves with a thermocompression press featuring an induction heating system. This equipment, LIT™ RAPID SOLAR, developed in partnership with Roctool, offers new and promising features.
Hydrogen has already been widely identified as a potential energy vector in the transition to renewables. However, a cost-competitive, zero-carbon hydrogen technology that can operate in both fuel-cell mode to produce electricity and in electrolyzer mode to produce hydrogen will be needed for widespread deployment to become a reality. The solid oxide electrolyzer/fuel cell (SOEC/SOFC) has emerged as a high-yield, reversible, and affordable solution.
Our power systems are changing. They are adapting to the introduction of decentralized and variable electricity production sources such as renewable energies, to the massive electrification of uses such as mobility, and to technological progress.
The ability to produce low-carbon, low-cost hydrogen at scale is vital to the development of a viable hydrogen industry. CEA-Liten is focusing its efforts on a high-yield hydrogen production technology called high-temperature electrolysis (HTE). To deploy HTE, electrolyzer cell durability is one area that will require further improvement—but it must not come at the cost of lower performance.
CEA-Liten's R&D practices integrate eco-design and eco-innovation from the very first stages of R&D programs. Around forty researchers use Life Cycle Analysis tools and technical-economic studies.
Thermal storage makes it possible to recover the heat lost in industry. The use of Phase Change Materials (PCM) is a relevant technological solution. CEA-Lite studied the commercial material HITEC and received an award for this work.
Grenoble, France startup WATTALPS, a CEA spinoff, is helping electrify the construction, farming, mining, transportation, shipping, logistics, warehousing, and sports vehicle markets with its immersion-cooled batteries for heavy equipment. The company recently announced that it raised €11 million in capital.
The heat generated by industrial processes can be captured and reused, reducing overall process-related energy consumption—a concept that is particularly promising for the food manufacturing industry. CEA-Liten brings years of thermal engineering expertise to innovative new waste heat recovery, storage, and reuse technologies, including a patented solution that can cut the primary energy consumption of batch sterilization processes by more than a third.
29.8% ! This great result record is the fruit of close collaboration between our teams and those of our partner 3SUN. It is our last certified efficiency record for a perovskite-on-silicon new-generation tandem photovoltaic cell measuring 9 cm² after shading correction.
A promising alternative for analyzing the famous current-voltage curve
CEA institutes ISEC, Irig, ISAS, and Liten collaborated on an integrated solar-powered methane production system for the EIC (European Innovation Council) artificial photosynthesis competition. The goal was to demonstrate autonomous operation of the system at the European Commission’s Joint Research Center in Ispra in summer 2022. The CEA was among the three finalists.
Stellantis and CEA, one of the world’s most innovative research institutions, today announced a new, five-year collaboration that targets in-house design of next-generation battery cells for electric vehicles.
Although solar photovoltaic energy production is considered a pillar of the energy transition, the technology is not without its own environmental drawbacks. The manufacturing of solar panels generates significant impacts and, as the current design do not anticipate the dismantling step, the panels are notoriously difficult to recycle at the end of their service life.
The largest international conference on research, technologies and applications in the biomass and bio-economy. This 32nd EUBCE will bring together 1,500 participants, 60 partners, 20 exhibitors and 20 European Horizon Europe projects to discuss the latest developments and innovations in the field, promote meetings and establish partnerships.
Evaluation carried out in the Atacama Desert reveals that the heterojunction technology panels developed by 3SUN and CEA outperform some of the best PERC technologies. After 18 months of measurement in a real-life environment, they show better efficiency and temperature resistance.
Startup SolReed is developing an all-in-one monitoring, maintenance, and repair unit for solar power plants that will extend solar panel lifespans. The CEA, active in solar energy, is assisting SolReed through its startup incubator. ENGIE Green, France’s leading solar energy company, has also supported SolReed since the startup was founded.
