H2 ecosystems

Since the turn of the millennium, we have been developing hydrogen technologies for our customers – from the initial laboratory concept to series‑ready systems. In doing so, we combine research expertise with extensive experience in industrial implementation.

This includes cell, stack, and system design, balance‑of‑plant optimization, controls, aging simulations and accelerated stress tests, as well as scale‑up concepts and manufacturing process development for electrolyzers and fuel cells, along with all other elements of the H2 infrastructure.

Battery energy storage system (BESS)

From cell chemistry to product integration: whether home storage or grid‑scale solutions, FEV e+r draws on a global team of engineers for product concepts, cost optimization, and quality assurance. At the world’s largest independent battery test center for high‑voltage systems, we test cells, modules, packs, and systems under real‑world load profiles, use the results for aging simulation models, and derive optimal operating strategies.

Battery Storage

Gensets & Combined-Heat-and-Power

Established technology – sustainable, cost‑efficient, and reliable. For almost 50 years, we have been developing internal combustion engines from the initial concept through to series production readiness. Through multiple genset turnkey solutions for customers, we have demonstrated deep component and system expertise. From product strategy and development to testing, benchmarking, and industrialization, we offer the full 360° range of services from a single source.
