As of 2025, China accounts for over 35% of global solar PV installations, but here's the kicker – it's the marriage between solar farms and giant "power banks" (read: energy storage systems) that's rewriting the rules of renewable energy. The solar PV and energy storage expo SNEC 2026 in Shanghai, China, was the place to see product launches and showcases from the big players. Taking place 3-5 June at Shanghai's National Exhibition and Convention Center (NECC), with attendance estimates running into the hundreds of thousands. Solar and storage industry leaders from China and Europe gathered in Germany this week to advance cross-border partnerships, launch a bilateral storage collaboration platform, and coordinate strategies for scaling PV and battery deployment amid surging demand, grid pressures, and intensifying. China has published a national plan to promote large-scale energy storage facilities, encouraging investment and broader participation in the electricity market. The 'Special action plan for large-scale construction of new energy storage (2025-2027)' was published last Friday (12 September). Its capacity of “new type” energy storage systems, such as batteries, quadrupled in 2023 alone. This rapid growth, however, has caused other problems, such as what one analyst described as “temporary structural overcapacity” and low utilisation. In this Q&A, Carbon Brief explores how China has been. CHN Energy has completed construction of a 400 MW solar-hydrogen-storage project in Jiangsu, combining coastal PV, battery storage and green hydrogen production in a single integrated system. The project, which includes a 60 MW/120 MWh battery and a hydrogen facility producing 482 tons annually, is. In 2024 China's clean energy investment was more than USD 625 billion, almost doubling since 2015.
