Celest

About

Founded in 2018, Celest is a government headquartered in Ulm, Germany specializing in Energy Storage, Hydrogen.

Celest is a research platform established in 2018 that addresses the full spectrum of electrochemical energy storage and conversion, from fundamental science to processing and application. The center operates at two locations in Baden-Württemberg, Ulm and Karlsruhe, pooling expertise from 31 institutes across three partner institutions. Core research areas include lithium-ion technology, energy storage beyond lithium (sodium, potassium, magnesium, calcium, aluminium, and chloride-ion batteries), hydrogen generation through water electrolysis, and fuel cell technologies. Celest hosts the Cluster of Excellence POLiS, Germany's only cluster of excellence in battery research, and operates the Graduate School Electrochemical Energy Storage (GS-EES), which transitions to an EES Academy in 2026. The center emphasizes interdisciplinary collaboration, technology transfer, and commercialization of new technologies, with particular focus on developing sustainable alternatives to traditional lithium-ion batteries for electric vehicles and stationary energy storage.
