On DaCES’ anniversary on 14 September 2023, we published our first report on energy storage in Denmark under the title: “Status, strengths and synergies – DaCES report on energy storage in Denmark 2023.” The report presents a mapping of the potential for and cases from a number of energy storage technologies: thermal energy storage, batteries, Power-to-X and system integration in an energy system based on renewable energy. In addition, we present 17 recommendations for how Denmark can strengthen its position as a green pioneering country in energy storage technologies, system integration and research for the benefit of Denmark and the green transition.
