Research Platform CELEST

The Energy Storage of the Future

Electrochemical energy storage is a key technology of the 21st century. In 2018, the Center for Electrochemical Energy Storage Ulm & Karlsruhe (CELEST), one of the most ambitious research platforms in this area worldwide, has started operation. It combines application-oriented basic research with close-to-practice development and innovative production technologies.

CELEST is a leading research platform dedicated to advancing the energy storage technologies that will power the future. Bringing together expertise from the Karlsruhe Institute of Technology (KIT), Ulm University, and the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), CELEST drives innovation from fundamental research at the atomic scale to the development, testing, and pilot production of new battery cells and energy systems. Its work focuses on lithium-ion technology, next-generation post-lithium batteries, hydrogen technologies, and other electrochemical storage solutions. By linking academic research with industry collaboration and technology transfer, CELEST accelerates the development of safer, more sustainable, and more efficient energy storage systems for a climate-neutral future.
