Cryogenic-temperatures cold storage is the Cinderella in thermal energy storage. According to the recent DOE global energy storage database, until now there are globally 166 thermal storage projects in operation or under construction for renewable energy time-shift/capacity firming or electric bill management, with a total capacity of 3365MW. However most of these projects are molten salt heat storage for concentrated solar power (CSP) plants (2552MW in total) and chilled water or ice slurry cold storage for demand side electricity consumption management (200MW). Only recent years the potential value of cryogenic-temperature cold storage has been widely recognised for the much elevated exergy density and the capability of cogeneration of cold and power. The related UK leading technologies those under development including cryogenic engine for transportation, liquid air energy storage, pumped thermal electricity storage etc, in which cryogenic temperature cold storage is a key to improve the performance. Moreover, with efficient and cost-effective cryogenic-temperature cold storage, the operation of traditional cryogenic systems can be more flexible as an effective mean of demand side management (consumes more off-peak electricity and less peak electricity instead of constant load operation to save electric bills). In a long term it will contribute to the creation of 'cold economy'.This project will develop Micro-encapsulated Phase Change Materials in Slurries (MPCMSs) as novel approaches of cryogenic-temperature cold storage. Slurries are excellent cold storage candidates as they can be transported by pumps (good fluidity), just like the molten salts in CSP plants. On the other hand with phase change materials (PCMs) encapsulated in the micro-size particles not only the equivalent heat capacity can be significantly improved, but also the temperature-dependent heat capacity can be designed easily by adding different capsules with appreciate freezing point core PCMs to minimize the exergy loss in charging/discharging processes.The key challenge of this approach is the wide working temperature range of MPCMSs from room temperature to cryogenic temperature. Therefore this project will utilize the applicants' developed skills and sophisticated research facilities in Micromanipulation lab (within School of Chemical Engineering, University of Birmingham) and new launched Birmingham Centre for Cryogenic Energy Storage (BCCES) to formulate, characterize, and demonstrate the application of MPCMSs for cryogenic-temperature cold storage. Through this project we will gain the skills of MPCMSs fabrication depending on the applications as well as the capability of optimal design of related cold storage devices.

低温冷藏是热能储存中的灰姑娘。根据能源部最近的全球储能数据库，到目前为止，全球有166个热储项目正在运营或在建，用于可再生能源时移/容量固定或电费管理，总容量为3365兆瓦。然而，这些项目大多是用于集中太阳能发电厂(CSP)的熔盐蓄热(总计2552兆瓦)和用于需求侧用电管理的冷水或冰浆冷藏(200兆瓦)。直到最近几年，低温冷藏的潜在价值才被广泛认识，因为它具有更高的(火用)密度和冷电联产的能力。英国正在开发的相关领先技术包括用于运输的低温发动机、液体空气蓄能、抽水蓄热等，其中低温蓄冷是提高性能的关键。此外，有了高效且经济高效的低温冷库，传统低温系统的运行可以更灵活地作为需求侧管理的有效手段(消耗更多的非高峰电力和更少的高峰电力，而不是恒定的负荷运行，以节省电费)。从长远来看，这将有助于“冷经济”的创造。本项目将开发微胶囊相变材料浆料(MPCMS)作为低温冷藏的新方法。浆液是很好的冷藏候选对象，因为它们可以通过泵运输(流动性好)，就像CSP工厂的熔盐一样。另一方面，将相变材料包裹在微米颗粒中，不仅可以显著提高等效热容量，而且可以通过添加不同冰点较高的相变材料胶囊来设计随温度变化的热容，以最大限度地减少充放电过程中的(火用)损失。这种方法的关键挑战是MPCMS的工作温度范围从室温到低温都很宽。因此，本项目将利用申请者在微操作实验室(伯明翰大学化学工程学院内)和新成立的伯明翰低温能量储存中心(BCCES)发展的技能和尖端的研究设施来制定、表征和演示MPCMS在低温冷藏中的应用。通过这个项目，我们将获得根据应用情况制作MPCMS的技术，以及相关冷藏设备的优化设计能力。
