The proposal aims to develop an inverse design methodology for an energy storage system of the Carnot battery type. The system will be able to store electric energy as internal thermal energy of a working fluid and is part of an overall energy system with fluctuating sources of renewable electric energy. The proposed Ruths storage system consists of two wet-steam storage tanks at different pressure, coupled by a compressor and an expansion device, so electric energy can be converted into internal thermal energy and vice versa. The size of the tanks and the fluid energy machinery must be well matched to the specific application, which could be an urban city housing district or an industrial production plant. The inverse design is started with an energy system analysis tool to find suitable boundary conditions, a first version of an appropriate technical design is returned back, so a first cost and feasibility assessment can be given. The procedure is repeated for optimization. The energy system analysis including cost functions will be handled by R. Niepelt, the technical design by S. Kabelac, both from the Leibniz University Hannover. Some special design features of the Ruths storage tank will be validated experimentally.

该提案旨在为卡诺电池类型的能量存储系统开发一种逆设计方法。该系统将能够将电能存储为工作流体的内部热能，并且是具有波动可再生电能来源的整体能源系统的一部分。所提出的Ruths储罐系统由两个不同压力的湿蒸汽储罐组成，并由压缩机和膨胀装置耦合，因此电能可以转换为内部热能，反之亦然。储罐和流体能机械的大小必须与具体应用相匹配，可以是城市住房区或工业生产工厂。利用能源系统分析工具进行反设计，寻找合适的边界条件，返回合适技术设计的初版，从而进行首次成本和可行性评估。为了优化，重复这个过程。包括成本函数在内的能源系统分析将由R. Niepelt负责，技术设计由S. Kabelac负责，他们都来自汉诺威莱布尼茨大学。鲁斯储罐的一些特殊设计特征将通过实验进行验证。
