China's hydrogen production capacity tops 51 million tonnes, renewable capacity doubles_我的网站
A | (ECNS) -- China’s annual hydrogen production capacity exceeded 51 million metric tons by the end of 2025, up about 1.4% from a year earlier, while actual output rose 7.3% to more than 39 million metric tons, according to a report released Tuesday by the National Energy Administration. Annual production capacity for renewable hydrogen already in operation surpassed 250,000 metric tons, more than double the level recorded in 2024. The report said hydrogen applications were continuing to expand across the industrial, transport and energy sectors. China had about 32,000 fuel-cell vehicles on the road by the end of 2025, with larger-scale deployment being explored along freight corridors and at ports. Globally, 66 countries and regions had released hydrogen development strategies by the end of 2025, together accounting for more than 90% of global GDP. (By Helen Mo, intern Yang Hongran)

Core castings for the world's most powerful onshore wind turbine Photo: website of Science and Technology Daily
The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft.
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.
