Recently, the world’s first ultra-high-temperature heat pump thermal energy storage system has been unveiled, marking a significant advancement in renewable energy storage and efficient utilization. Developed by an international research team, this innovative technology employs an advanced heat pump cycle capable of stable operation at temperatures exceeding 500°C, dramatically increasing both thermal energy storage density and system efficiency. Conventional heat pumps typically operate below 100°C, making them unsuitable for industrial high-temperature applications. In contrast, this ultra-high-temperature heat pump not only overcomes that limitation but also efficiently converts electricity into high-grade thermal energy for long-term storage—ideal for energy-intensive sectors such as steel, cement, and chemical manufacturing. Moreover, the system can be integrated with intermittent renewable sources like wind and solar power, storing heat during periods of surplus electricity and releasing it when needed, thereby enhancing grid flexibility and overall energy efficiency. Experts highlight that this breakthrough could substantially reduce industrial carbon emissions and serve as a key enabler for achieving global ‘dual carbon’ (carbon peak and carbon neutrality) goals. Pilot projects are already underway in Europe and Asia, with commercial deployment expected within the next five years.
近日，全球首套超高温热泵储能技术正式面世，标志着可再生能源存储与高效利用迈入新阶段。该技术由国际科研团队联合开发，通过创新的热泵循环系统，可在高达500℃以上的温度下稳定运行，显著提升了热能储存密度与系统效率。传统热泵通常工作在100℃以下，难以满足工业高温用热需求；而超高温热泵不仅突破了这一限制，还能将电能高效转化为高温热能并长期储存，适用于钢铁、水泥、化工等高耗能行业。此外，该系统可与风电、光伏等间歇性可再生能源耦合，在电力富余时储热、缺电时释热，有效提升电网灵活性和能源利用率。专家指出，这项技术有望大幅降低工业碳排放，为实现‘双碳’目标提供关键技术支撑。目前，示范项目已在欧洲和亚洲同步启动，预计未来五年内实现商业化推广。
