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.

全世界对储能都很感兴趣，目前仍以抽水蓄能为主。本项目将考虑的基于热存储（与化学电池等相反）的新系统由于其相对高的能量密度和低的材料成本而显示出特别的前景。该项目将有助于在这一领域的工作，已经在CUED进行了几年，并获得了良好的认可，在国内和国际上。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，并基于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，很少有工作流体的性能进行了比较，跨临界循环已经相对稀疏的研究。这将主要是基于计算机的，周期分析方法用Matlab或Python编码。此外，该项目将包括为上述周期配置开发准确的成本模型。这将实现其成本效益优化。
