There is much interest worldwide in energy storage, which is still currently dominated by pumped hydro. The new systems based on thermal storage (as opposed to chemical batteries and the like) that will be considered in this project show particular promise due to their relatively high energy density and the low cost of materials. This project will contribute to the body of work in this area that has been undertaken at CUED for several years and received excellent recognition, both nationally and internationally. It will link in to the EPSRC-funded Generation-Integrated Energy storage work.The project aims to explore the range of working fluids and cycle configurations (especially transcritical cycles) for thermo-mechanical energy storage technologies and develop design rules based based on concepts such as power density and energy density. In the current literature, few working fluids have been compared in terms of their performance, and transcritical cycles have been relatively sparsely studied. This will be mainly computer-based, with cycle analysis methods coded in Matlab or Python.Furthermore, the project will include developing accurate cost models for the aforementioned cycle configurations. This will enable cost-efficiency optimisation thereof.

全球范围内对储能很感兴趣，目前仍以抽水蓄能为主。该项目中将考虑的基于热存储（相对于化学电池等）的新系统由于其相对较高的能量密度和较低的材料成本而显示出特别的前景。该项目将为 CUED 多年来在该领域开展的工作做出贡献，并获得国内外的高度认可。它将与EPSRC资助的发电集成储能工作相结合。该项目旨在探索热机械储能技术的工作流体和循环配置（特别是跨临界循环）的范围，并根据功率密度和能量密度等概念制定设计规则。在目前的文献中，很少对工作流体的性能进行比较，并且跨临界循环的研究相对较少。这将主要基于计算机，并使用 Matlab 或 Python 编码的周期分析方法。此外，该项目还将包括为上述周期配置开发准确的成本模型。这将实现其成本效率优化。
