Approaching the topics:

Developing and understanding batteries through atomic scale simulations by Piotr de Silva (Asst. Prof.) and Ivano Eligio Castelli (Asst. Prof.), DTU Energy

Battery research at DTU was re-initiated in 2010 with theoretical calculations on the aprotic Li-O2 cell chemistry, and nowadays involve a wide array of experimental and theoretical activities. Some of the key strengths of the battery research track at DTU Energy on the experimental side are electrochemical methods (electrochemical impedance spectroscopy, differential electrochemical mass spectrometry) and structural characterization methods (Quasi-elastic neutron scattering, X-ray crystallography). Detailed impedance investigations have been carried out on several battery electrode types and parameterized using porous electrode theory. In-situ investigations using combined electrochemical and structural techniques for interfacial and structural characterization is an area where significant advances have been made in recent years. On the theoretical side much effort has been dedicated to electronic structure calculations primarily using density functional theory, DFT. Our DFT studies have focused on describing the overpotentials due to the formation of the discharge products in metal-air batteries, paying special attention to the influence of impurities on them. We have also examined the charge transport processes across these discharge products, which involve both electron tunneling and polaronic hopping, and use machine learning methods in conjunction with DFT and other types of computational methods to accelerate identification of new energy storage materials. This presentation aims at providing an overview of our current battery research along with more detailed examples of activities in the area of redox flow batteries and within Li-ion batteries.

Hybrid solutions with Danfoss Drives frequency converters by Helge Jensen, Danfoss

Energy storage and hybrid technology provide improved stability and increased energy efficiency in many systems and introduces new capabilities to handle peak loads, saving excess energy for use when needed and enhances backup power for emergencies. Therefore, in recent years, more and more focus has been on battery and hybrid solutions.

Danfoss Drives has also had a lot of focus on the issue of battery and hybrid solutions. Therefore, we now offer you a space for this afternoon event with IDA, where you will be updated with exciting information about new initiatives and general aspects of this area.

Practical examples on large energy storage solutions in Denmark by Anders Dyrelund, Ramboll

The world population is growing and more people wants to live in cities. In order to meet the UN Sustainable Development Goals it is vital that the infrastructure of the cities are planned and designed to meet these goals in a cost effective way. The need for low carbon energy is a challenge, but cities have an opportunity to benefit from the economy of scale and plan smart solutions, which can integrate the renewable and surplus energy for heating and cooling. The low carbon sources for heating and cooling are either of low quality or fluctuating. An increasing share of electricity is also produced from fluctuating sources such as solar and wind, which do not always meet the demand. An important feature of the smart city is that district energy systems which are cost effective in the cities compared to individual solutions, can include large thermal storages for heat and cold combined with heat pumps, electric boilers and CHP plants. Such systems offer large capacities that can respond efficiently on the fluctuating electricity production and prices. The electric boilers consume large capacities at very low prices and can prevent curtailing of excess power from solar or wind. The heat pumps have a steady consumption, but can interrupt at high prices. The CHP plants operate in the market only at high prices or if needed to support the power system. In fact, the thermal system acts like a huge electric battery - only much more cost-effective than ordinary electric batteries. In the longer term, the fast regulating CHP plants can be based on renewable gas, produced by surplus wind energy and stored in gas storages.

The District heating company in the Danish town Gram has installed a large heat storage pit in combination with large-scale solar heating for 60% of the production, and the remaining 40% is divided between an electric boiler, a heat pump and a gas fueled CHP. The district heating system in Greater Copenhagen supplying 70 million of heated floor, has so far utilized the potential for surplus low quality heat from waste and from the power generation in CHP plants. It is now in the transition to include combined heating and cooling with large heat pumps, electric boilers and larger thermal storage pits. Both systems are described in an EU-report on 8 selected cases for district heating and cooling the EU.
