Research topics :

• Batteries: The research in the Department of Energy Conversion and Storage targets new battery types with improved energy density, power density, durability and stability. We develop, characterize and test novel materials, cells and battery packs, in close collaboration with national and international research institutions and industry

• Electromechanical converters: Our main focus is on functional metal oxides for conversion of mechanical to electrical energy (and vice versa), but other applications, e.g., as actuators, resonators or sensing, are also considered. The research builds on the extensive materials and processing knowledge within ceramics which exists in the department. Although piezoelectrics in many ways are a mature field, a push towards miniaturization and increasing societal restrictions on the use of lead-containing compounds have opened up opportunities for new classes of materials and processing methods. Currently, most activities in the department are on materials development and processing but device design, fabrication and testing are also envisaged.

• Solid oxide fuel cells: We have been doing SOFC research since the late 1980s. Today, we are among the world leaders in this field. Our research ranges from fundamental investigations of materials and their structural and electrochemical properties to the manufacture of complete cells with industrially relevant processes. Thus, our process lab facility has the capacity to produce thousands of cells. Moreover, we have extensive knowledge about advanced characterization and testing of fuel cells which makes it possible to investigate their electrochemical performance in great detail. Sophisticated equipment allows us to measure the mechanical and microstructural properties that are very important for cell lifetime.

• Gas separation: Separation of gases has numerous applications of relevance to sustainable energy systems, including manufacture of pure oxygen for oxygen blown power plants (facilitating CO2 removal from the waste stream) and separation of CO2 from biogas to upgrade it to biomethane. Our research addresses two technologies for gas separation: oxygen transfer membranes (OTMs), based on selective transport of oxygen ions through a gas tight ceramic membrane at high temperatures, and gas adsorption processes such as pressure
  swing adsorption (PSA)

• Caloric cooling and heating: The department has managed a number of major research projects which have led to the building of two magnetocaloric demonstration devices with a third, to be used as a domestic heat pump, under construction. Our effort covers all the different aspects of caloric cooling, from materials research, regenerator design, heat transfer and flow modelling, permanent magnet optimization and systems design and construction. Notable achievements have been the highest performance magnetic refrigeration device and the first demonstration of an elastocaloric regenerator

• Solid oxide electrolysis cells: The Department of Energy Conversion and Storage has been one of the originators of the field of solid oxide electrolysis. Recent notable achievements include a much improved understanding of the degradation mechanisms of the fuel electrode and means of counteracting it, demonstration of high-pressure operation at the stack level, and the commercial availability of a CO-producing unit from the Danish company Haldor Topsøe, using licensed technology from the department.

• Magnets: Magnetic fields can be created either by magnetic materials (permanent magnets) or by an electrical current (electromagnets). At DTU Energy we do research on both permanent magnet systems and superconducting magnets, where the magnetic field is created by a current in a superconducting material. Our main focus is the design and modelling of magnet structures where a number of magnets are combined to create a magnetic field with specific properties. The aim can be to create a very homogeneous field in a certain volume; such magnets can by used for nuclear magnetic resonance, e.g. in MRI scanners for medical purposes. Another example is to design a magnet creating volumes with a very high magnetic field alternating with volumes with almost no field. This is the aim when developing a magnet for magnetic refrigeration
