Core Viewpoint - The report highlights the critical role of new energy storage in supporting the new power system and achieving the "dual carbon" strategic goals, emphasizing the need for top-level design, addressing development bottlenecks, and strategic layout for the new energy storage industry during the 14th Five-Year Plan period [2]. Group 1: Top-Level Design and Industry Practice - A comprehensive policy framework has been established, with new energy storage included in the Energy Law of the People's Republic of China, marking its legal position in power system regulation [3]. - By the end of 2024, the installed capacity of new energy storage in China reached 73.76 million kilowatts, accounting for over 40% of the global total, with an average annual growth rate exceeding 130% [4]. - Technological innovation has led to significant advancements, including the mass production of lithium-ion battery cells with a capacity of 500 ampere-hours and a cycle life of 15,000 times [5]. Group 2: Bottlenecks in High-Quality Development - Despite a 25% decrease in lithium-ion battery storage costs compared to 2023, the initial investment for long-duration storage (over 4 hours) remains high, with vanadium flow battery systems costing 1.6 to 2.5 times that of lithium-ion batteries [6]. - The current standards primarily cover electrochemical storage, but there are systemic challenges in the implementation of these standards, highlighting the need for enhanced execution and regulatory oversight [7]. - The industry chain has weak links, particularly in high-end products, which still rely on imports, indicating a need for improved collaboration between research, development, and engineering [9]. Group 3: Leading Global Energy Storage Paradigm - A focus on technological innovation across various time scales is essential, with plans to upgrade lithium-ion batteries and accelerate the industrialization of sodium-ion and solid-state batteries [10]. - The establishment of a unified capacity compensation mechanism and a three-pronged revenue model is necessary to unlock diverse value opportunities for new energy storage [11]. - The report advocates for the internationalization of storage technology standards and the establishment of integrated projects in overseas markets, aiming to position China as a leader in the global energy storage industry [12].

Core Viewpoint - The Hebei Provincial Development and Reform Commission has initiated a call for applications for independent energy storage pilot projects utilizing diverse technological routes, aiming to promote the high-quality development of new energy storage systems [8][9]. Group 1: Project Overview - The pilot project aims to select a range of promising energy storage technologies, including gravity, sodium-ion, vanadium flow, hydrogen storage, solid-state batteries, and deep space energy storage [9]. - The total scale of the pilot projects is planned to be no more than 3.5 million kilowatts, with each city allowed to recommend no more than five projects [2][10]. Group 2: Application Requirements - Individual project capacity is generally set at 100,000 kilowatts, with a maximum of 200,000 kilowatts. For projects using "lithium iron phosphate + X" mixed storage technology, the lithium iron phosphate component must not exceed 90% [3][11]. - Project site selection must include a comprehensive safety risk assessment and maintain a safe distance from adjacent buildings and facilities, avoiding permanent farmland and protected ecological areas [4][11]. Group 3: Timeline and Responsibilities - Projects must commence construction within nine months and connect to the grid within 15 months. Failure to start construction on time will result in the cancellation of the project plan [5][11]. - The project implementation entity is responsible for adhering to the approved scale and timeline for construction [5][11]. Group 4: Application Process - Local energy authorities are tasked with organizing applications, prioritizing projects that support grid regulation and renewable energy consumption [12]. - The provincial development and reform commission will review applications, seek opinions from provincial grid companies, and conduct expert evaluations to determine the final list of pilot projects [12][13]. Group 5: Implementation and Safety - Local governments must ensure the smooth implementation of pilot projects, coordinating with various departments and addressing any challenges encountered during construction [14]. - Safety regulations must be integrated throughout the project lifecycle, with clear responsibilities assigned to ensure compliance with safety standards [14].
