China releases New-type Energy Storage Technology Development Roadmap (2025-2035)

⁠⁠⁠⁠⁠⁠⁠China's Ministry of Industry and Information Technology (MIIT) released the New-type Energy Storage Technology Development Roadmap (2025-2035) on Wednesday at the main forum of the World Energy Storage Conference 2025, providing guidance and reference for further promoting high-quality industrial development and high-level industrial security.

This roadmap focuses on five key subfields: electrochemical energy storage, mechanical energy storage, electromagnetic energy storage, cold thermal energy storage, and hydrogen storage. It outlines key products, essential materials and components, as well as development goals for various fields leading up to 2035.

"From a national perspective, the roadmap systematically evaluates the development status of different technology industrial chains. On the enterprise level, it also presents specific indicators for product development and outlines future development direction," said Zhang Yanli, associate researcher at the Equipment Industry Development Center of the MIIT.

Currently, the country's new-type energy storage technologies are developing rapidly, with a surge of innovative achievements emerging.

A newly released energy storage system in China is the world's first to achieve zero degradation over five years and can be mass-produced on a large scale. It boasts a storage capacity of 6.25 megawatt-hours (MWh) of high energy within a single 20-foot container, with energy density increased by 30 percent.

Meanwhile, the application scenarios for new technologies are also continuously expanding. At present, Shanghai's Mingdong Container Terminal, a key hub for global trade, is undergoing new energy transformation of fuel equipment.

"Custom battery packs have been specifically developed, featuring an electrophoretic powder coating and painting process on the battery housing, making them fully capable of withstanding the high-salinity and high-humidity environment of the port," said Zhou Gong, product engineer at China's CATL, the world's largest battery maker.

In the first half of this year, the country's installed capacity of new-type energy storage had reached 94.91 million kilowatts, representing an increase of approximately 29 percent compared to the end of 2024.

China's research icebreaker Xuelong, or Snow Dragon, departed Christchurch, New Zealand for the 42nd Antarctic Expedition on Thursday after completing resupply operations.

The vessel arrived at New Zealand's Lyttelton Port Sunday evening.

During its stay in Lyttelton, the vessel took on 1,200 tons of light oil and replenished supplies including vegetables, fruits, and fresh water.

The light oil will be brought to China's Zhongshan Station in Antarctica, exclusively for fixed-wing aircraft.

Thirty four new crew members boarded the ship in Lyttelton to commence oceanographic operations.

The supplies of fruit, vegetables and other food items include not only items for the Xuelong crew but are also destined for the Qinling Station.

"The Qinling Station has a longer overwintering period, so they will run out of fruits later in the season. To better support their daily needs, we've replenished large quantities of green vegetables, fruits, beverages, as well as beef and mutton," said Li Donghui, the service team leader of the Xuelong vessel.

During its port call, the Xuelong also completed a freshwater replenishment of approximately 600 tons. The freshwater is primarily for drinking and kitchen use, serving as vital daily supplies for the expedition team during their subsequent fieldwork.
