Introduction of renewable and intermittent photovoltaic and wind electricity sources in the utility grid will increase the demand for stationary electrical energy storage technologies. In such applications high energy density has less importance, while a low cost has highest priority. This is currently not met by any of the state-of-the-art batteries like Li-ion or NiMH batteries. However, the main driver for battery development for the past decades has been for mobile applications (electric vehicles and consumer electronics) where large energy density has highest priority. For stationary power applications energy density is less important while cost, lifetime and safety is paramount. This has created a driver for R&D in new (aqueous) battery chemistries where these goals are meet.
Current research topics within membranes and energy conversion include synthesis/characterisation of ion conducting polymer membranes for electrochemical energy conversion applications, solid state batteries, redox flow batteries and solar charging of redox flow battery electrolytes with photoelectrochemical cells’.
Besides energy conversion sensor technology is also an active field of research in the group. It is application-oriented and current focus is detection and measurement of particles, flow (speed) in fluids and gases and measurement of biofilm/fouling with relevance within a range of industrial and biomedical applications.
