全球首套超高温热泵储能技术发布

Core Viewpoint - The State Power Investment Corporation has officially launched the world's first ultra-high temperature heat pump energy storage technology, named "Shunuo," which offers significant advantages over traditional energy storage methods [1]. Group 1: Technology Overview - "Shunuo" technology features high flexibility in deployment, not reliant on specific geographical conditions, allowing for quick installation in various settings such as flat power stations and mountainous industrial parks [1]. - The heat pump energy storage, also known as the Carnot battery, combines heat pump cycles with heat engine cycles to achieve efficient bidirectional conversion between electrical and thermal energy [1]. - The technology boasts high energy density, low capacity costs, and high storage efficiency, enabling high-quality combined heating, cooling, and electricity supply [1]. Group 2: Performance Metrics - The "Shunuo" technology maintains stable efficiency without degradation across different loads, with thermal storage capabilities exceeding 560°C and as low as -60°C [1]. - The energy storage density can reach 80-120 kilowatt-hours per cubic meter, significantly surpassing conventional compressed air energy storage, with a potential increase in storage capacity by over ten times in the same space [1]. Group 3: Application and Impact - The technology has broad application scenarios, including coupling with large-scale renewable energy bases, coal power, nuclear power, and high-energy-consuming industries, thereby enhancing the proportion of green electricity and meeting flexibility and energy-saving requirements [1]. - Driven by the "dual carbon" goals, long-duration energy storage has transitioned from an optional choice to a necessity for energy transformation, making the innovation and application of long-duration energy storage technologies urgent [1]. - Heat pump energy storage technology is expected to play a crucial role in constructing a new power system and ensuring the safe and stable operation of the power grid, positioning it as a backbone for future large-scale long-duration energy storage [1].
