China’s Huawei has built a 400 MW/1.3 GWh solar-plus-storage off-grid facility in Red Sea New City, Saudi Arabia.

Researchers in China have proposed a new lithium-free doping strategy to fabricate spiro-OMeTAD-based hole transport layers (HTLs) for applications in perovskite solar cell. A PV device built with a salt-doped HTL achieved a record-breaking efficiency of 25.45%.

This year’s edition of the China International Energy Storage Expo (EESA EXPO) has underlined the latest energy density achievements in the battery energy storage space on both cell and system levels. Meanwhile, the sheer number of commercial and industrial (C&I) systems on display spoke of growing demand in this market segment. Alternative lithium-ion battery chemistries were not easy to find.

China’s Ministry of Commerce has described the Office of the US Trade Representative’s recent decision to raise tariffs on Chinese solar components, batteries, semiconductors, steel, and EVs as “typical unilateralism and protectionism.” It added that the tariff increases will harm US companies and consumers.

The novel method uses the YOLOv8 framework, integrating an attention mechanism and a transformer model. It was tested on a dataset of 4,500 electroluminescence images against several other models and its results were up to 17.2% more accurate.

Researchers in China have found that a special type of hygroscopic hydrogel made of the polyacrylamide polymer and lithium chloride may reduce PV module temperature by up to 7.5%. They have also developed a mathematical model to analyze the operational mechanisms and factors responsible for the cooling performance.

The 30 MW plant is the first utility-scale, grid-connected flywheel energy storage project in China and the largest one in the world.

King Abdullah University of Science and Technology researchers have told pv magazine that hydrogen storage pipelines and gravel could become a reality in lakes or water reservoirs in Europe, the United States, Japan, or China within 10 years. “The technology required to implement the proposed system is available, simple and cheap,” they said.

Aiko Solar, GoodWe, and Ginlong Solis have all posted declines in net profit for the first half of 2024 due to industry overcapacity.

The Dengkou Renewable Energy Storage Project is billed as the largest single-capacity energy storage station under construction in China.
