The research areas of the Abel group include projects in the field of energy conversion, materials, methods development, and industrial applications. If possible, we transfer the technologies into innovations and ultimately into business.

Energy-related materials research includes energy production, storage, and conversion. We are therefore active in curiosity-driven fundamental research, engineering technology, as well as applied research. The group is known for strong R&D and applications, as well as transfers of innovations into business and spin-off companies.

Methods Development

We develop unique equipment and technologies in the field of a) mass spectrometry, b) micro- and nanospectroscopy, c) materials science, d) sensor concepts, and e) space related technologies.

Energy Conversion

Energy-conversion is a central research area of the Abel group. It spans across the full spectrum of energy production, transport, storage and conversion. Beyond curiosity-driven fundamental research, we also focus on applied research in collaboration with industry. This includes in particular methods development in the field of fuel cells.
