宾夕法尼亚州立大学研究:住宅热泵搭配碳酸钾基热化学储能
Pairing residential heat pumps with potassium carbonate-based thermochemical storage
美国宾夕法尼亚州立大学团队评估了住宅热泵与碳酸钾基热化学储能(TCES)结合的长时储能方案,在纽约市一座220.82 m²单户住宅中模拟2050年95%脱碳电网下的运行。参考系统需68 kWh储热与168 kWh电池容量,电池承担大部分储能响应;在最有利于储热的场景下优化后TCES容量需求为894 kWh。团队提出两条改进路径:将TCES充电效率从45%提升至65%,或将热泵COP至少提高25%。
