A research report from CICC highlights the rapid evolution in the hybrid energy storage sector, showcasing a definitive shift towards large-scale projects. Notably, long-duration energy storage solutions are poised to spearhead development in regions characterized by extensive deployment of new energy sources or abundant natural resources. The integration of lithium-ion batteries with other advanced long-duration storage technologies is gaining traction, as diverse energy storage methods complement each other to address the requirements of varied applications. This trend towards large-scale, long-duration energy storage is firmly established, fueled by both policy incentives and economic considerations. Consequently, regions with significant installations of new energy sources or favorable resource endowments are anticipated to witness a surge in the rapid development of long-duration energy storage projects.
