项目摘要

The cooling sector currently consumes around 14% of the UK's electricity and emits around 10% of the UK's greenhouse gases. Global electricity demand for space cooling alone is forecast to triple by 2050. Moreover, as air temperature increases, the cooling demand increases, but a refrigerator's Coefficient of Performance decreases. This results in a time mismatch between a refrigerator's efficient operation and peak cooling demand over a day. Clearly, this problem will deteriorate over the coming decades. Indeed, research by UKERC recently reported that cooling sector will cause a 7 GW peak power demand to the grid by 2050 in the UK. A solution is to employ cold thermal energy storage, which allows much more flexible refrigeration operation, thereby resulting in improved refrigeration efficiency and reduced peak power demand. Large-scale deployment of cold thermal energy storage could dramatically reduce this peak demand, mitigating its impact to the grid. Moreover, the UK curtails large amounts of wind power due to network constraints. For example, over 3.6TWh of wind energy in total was curtailed on 75% of days in 2020. Therefore, through flattening energy demand, cold thermal energy storage technology provides a means to use off-peak wind power to charge cold thermal energy storage for peak daytime cooling demand. This project, based on the proposed novel adsorption-compression thermodynamic cycle, aims to develop an innovative hybrid technology for both refrigeration and cold thermal energy storage at sub-zero temperatures. The resultant cold thermal energy storage system is fully integrated within the refrigerator and potentially has significantly higher power density and energy density than current technologies, providing a disruptive new solution for large scale cold thermal energy storage. The developed technology can utilise off-peak or curtailed electricity to shave the peak power demand of large refrigeration plants and district cooling networks, and thus mitigates the impacts of the cooling sector on the grid and also reduces operational costs.

目前，制冷行业消耗了英国约14%的电力，排放了约10%的温室气体。据预测，到2050年，仅太空制冷方面的全球电力需求就将增加两倍。此外，随着空气温度的升高，制冷需求增加，但制冷机的性能系数降低。这导致冰箱的高效运行与一天的峰值冷却需求之间的时间不匹配。显然，这个问题将在未来几十年恶化。事实上，UKERC最近的研究报告称，到2050年，冷却部门将导致英国电网的电力需求达到7GW的峰值。一种解决方案是使用冷热能存储，这使得制冷操作更加灵活，从而提高了制冷效率，减少了峰值电力需求。大规模部署冷热能存储可以极大地减少这一高峰需求，减轻其对电网的影响。此外，由于网络限制，英国削减了大量的风力发电。例如，2020年总计超过3.6TWh的风能被削减了75%的天数。因此，冷蓄能技术通过平坦化能源需求，提供了一种利用错峰风电对高峰期日间供冷需求进行冷储能充电的手段。该项目以拟议的新型吸附-压缩热力循环为基础，旨在开发一种创新的混合技术，用于零度以下的制冷和冷热能储存。由此产生的冷热能存储系统完全集成在冰箱中，潜在地具有比现有技术更高的功率密度和能量密度，为大规模冷热能存储提供了一种颠覆性的新解决方案。开发的技术可以利用非高峰或削减电力来削减大型制冷厂和区域冷却网络的高峰电力需求，从而减轻冷却部门对电网的影响，并降低运营成本。
