The inexpensive, location-independent, and resource-saving storage of electrical energy is the central unsolved problem in the transition to fluctuating energy sources. One possible solution would be the emerging technology of Carnot batteries (CBs), where electrical energy is converted into heat by high-temperature heat pumps, which are then stored in inexpensive materials such as water, stones, or molten salts, and then converted back into electrical energy as needed, e.g., by means of steam turbines. The thermodynamic principle has been known for a long time, nevertheless there are so far no general methods for their design or their evaluation based on the fundamentals and the objectives. Carnot batteries are complex coupled, time-varying systems with a large number of components and degrees of freedom. Published efficiencies and costs are rarely verified or apply only to specific systems; integration into future energy markets is unexplored. The fundamentally new approach of this priority program (SPP) is the comprehensive inverse top-down design methodology, which, starting from the target variables (market) step by step towards the smaller, aims at the optimal design as well as optimal modes of operation, with corresponding cycles, storages, machines, and fluids (molecule), and in turn optimally combines these components - which have not been considered so far. Especially the working fluids and their mixtures are co-optimized with the process configurations and process parameters to find the technical and economical limits. The market needs and the limits of CBs is to be investigated by an interdisciplinary SPP team. By building up a new interdisciplinary community, a high methodological and content-related gain in knowledge is expected, which is transferable to further energy-technological questions. This will be done in the inversely arranged project areas, which build on each other and cooperate intensely: A - Carnot batteries in energy markets, B - Design of Carnot batteries, C - Components for Carnot batteries. The work of the SPP will be pooled and validated by a shared Carnot battery laboratory, which will be set-up within the coordination project and can be used by the participants of the SPP for validation of their models and for investigating the coupling of different interconnected parts of a CB. The cooperation and exchange between the participants will be coordinated, by organizing workshops, student exchanges, seminars, and includes the involvement of internationally renowned scientists from different disciplines. The management of research data will be facilitated and managed by the coordination project, as well as the communication of the results to the public.

电能的廉价、位置无关和资源节约的存储是向波动能源过渡的中心未解决的问题。一种可能的解决方案是新兴的卡诺电池（CB）技术，其中电能通过高温热泵转换为热量，然后将其储存在廉价的材料中，如水，石头或熔盐，然后根据需要转换回电能，例如，通过蒸汽涡轮机。热力学原理早已为人们所知，然而，迄今为止，还没有基于基本原理和目标的通用方法来设计或评估它们。卡诺电池是一个复杂的耦合，时变系统，具有大量的组件和自由度。公布的效率和成本很少得到核实，或仅适用于特定系统;未探讨如何融入未来能源市场。该优先计划（SPP）的全新方法是全面的逆向自上而下设计方法，从目标变量（市场）开始逐步向较小的方向发展，旨在优化设计以及最佳操作模式，以及相应的周期，存储，机器和流体（分子），并反过来优化组合这些组件-迄今为止尚未考虑过。特别是工作流体及其混合物与工艺配置和工艺参数进行了协同优化，以找到技术和经济极限。市场需求和CB的局限性将由跨学科的SPP团队进行调查。通过建立一个新的跨学科社区，预计将在方法和内容方面获得很高的知识，这些知识可以转移到进一步的能源技术问题上。这将在相反安排的项目领域进行，这些领域相互建立并密切合作：A -能源市场中的卡诺电池，B -卡诺电池的设计，C -卡诺电池的组件。SPP的工作将由一个共享的卡诺电池实验室进行汇总和验证，该实验室将在协调项目内建立，可供SPP的参与者用于验证其模型和研究CB不同互连部分的耦合。参与者之间的合作与交流将通过组织研讨会，学生交流，研讨会进行协调，并包括来自不同学科的国际知名科学家的参与。协调项目将促进和管理研究数据的管理，以及向公众通报研究结果。
