Sweden has a long and strong tradition in research on materials for energy applications, such as batteries, fuel cells, and solar cells, to name just a few. Neutrons are often ideally matched to study the structure and dynamics of these materials, especially in regard to their high penetration depth and concomitant ability to probe the behavior of materials under working conditions such as in an operating fuel cell.

Examples of recent highlights in this area are from the research group of Maths Karlsson at Chalmers University of Technology; here fundamental key properties of local structure and its correlation to proton transport in proton conducting oxides were studied using neutron spectroscopy.
