📄 Abstract（原文）
Thermal energy storage technology can address the temporal, spatial, or intensity mismatch between supply and demand of zero-carbon thermal energy, and represents one of the key technologies for achieving carbon neutrality in building and urban energy systems. For district heating systems in northern urban areas of China, if various types of low-grade waste heat collected throughout the year can be stored via seasonal thermal energy storage technology, these heat sources can be fully utilized...
