China Advances Green Energy and High-Tech Materials with Major Industrial Projects

China's First Integrated Green Hydrogen and Coal Chemical Project Enters Full Commercial Operation

On 20 November, China Datang's 150MW integrated wind-solar-storage hydrogen production demonstration project in Duolun commenced full-scale commercial operation. This marks China's inaugural demonstration project integrating green hydrogen with coal chemical processes. The initiative overcame core technological challenges by establishing a deep adjustment mechanism for large-capacity electrolysers in renewable grid-connected hydrogen production. It achieved China's first breakthrough in enabling sustained, stable operation of large-capacity electrolysers within the chemical industry, filling a significant sector gap. The project secured 28 invention patents, published three corporate standards, and was successfully included in the National Energy Administration's inaugural list of hydrogen energy pilot projects. It is projected to produce 70.59 million cubic metres of hydrogen annually, reducing carbon dioxide emissions by 138,800 tonnes – an environmental benefit equivalent to the carbon sequestration capacity of 1,400 hectares of mature forest over one year.

Longhua New Material's Polyether Polyol Expansion Project Commences Production On 20th November, Longhua New Material announced that its 330,000-tonne-per-year polyether polyol expansion project has been fully completed and has successfully produced qualified products. With a total investment of RMB 150 million, the project primarily produces high-activity flexible foam polyether polyols and polyether polyols for CASE applications, serving sectors including automotive, footwear and apparel, adhesives, and foam adhesives. Upon commissioning, the company's total polyether product capacity will reach 1.29 million tonnes per annum.

Plans for Wuhu High-Purity Hydrogen Facility Unveiled

Wuhu High-Purity Hydrogen Production Project Public Notice On 18 November, Baoying (Wuhu) Electronic Specialty Gases Co., Ltd. released a pre-approval notice for the design plan of its high-purity hydrogen production project. The project proposes constructing a hydrogen production station, filling station, air compressor station, and production support building to establish a high-purity hydrogen production facility. Upon completion, the facility is projected to achieve an annual production capacity of 12.96 million standard cubic metres of high-purity hydrogen, 1.8 million standard cubic metres of electronic-grade hydrogen, 172.8 million standard cubic metres of high-purity helium, 240 million standard cubic metres of compressed air, 210,000 cylinders of high-purity hydrogen, 140,000 cylinders of hydrogen-nitrogen and hydrogen mixtures, alongside other photoresist-supporting specialty gases.

Shandong Invests in Sodium-Ion Battery Material Production

Shandong Adds 25,000 Tonnes of Sodium-ion Battery Hard Carbon Material Recently, Shandong Zhongxin Sodium Energy New Materials Industry Co., Ltd. invested 1 billion yuan to establish the first phase (25,000 tonnes) of a sodium-ion battery hard carbon anode material project in Yucheng, Dezhou, Shandong. This initial phase marks the pioneering stage of a 25,000-tonne hard carbon anode material production layout. It will establish five state-of-the-art intelligent automated production lines and one R&D pilot line, achieving an annual output capacity of 25,000 tonnes upon full operation.

Research Breakthrough Paves Way for Rare Earth Electroluminescence

Chinese research team unveils latest breakthrough in rare earth materials Recently, Associate Professor Han Sanyang's team at Tsinghua Shenzhen International Graduate School, in collaboration with Heilongjiang University and National University of Singapore, published groundbreaking research titled ‘Capturing Electro-Excited Excitons for Tunable Rare Earth Nanocrystal Electroluminescence' in the journal Nature. National University of Singapore. Titled ‘Tunable electroluminescence in rare-earth nanocrystals via capture of photo-generated excitons,' the findings were published online in Nature, clearing a key hurdle for the industrial application of rare-earth materials in modern optoelectronic technologies. It is understood that rare-earth nanocrystals (lanthanide-doped nanocrystals) are regarded as promising candidates in the field of electroluminescence due to their advantages of tunable emission colours, narrow spectral lines, and high stability. However, the insulating properties of this material prevent direct current injection, long hindering its application in modern direct-current electroluminescent devices such as LEDs and OLEDs. Addressing this core bottleneck, the collaborative team innovatively proposed an organic-inorganic hybrid strategy. Through surface modification, they effectively “clad” the rare-earth nanocrystals in an “energy conversion mantle”. This organic molecular interface precisely regulates the energy level structure, enabling efficient transfer of exciton energy to the rare-earth ion luminescent centres. This breakthrough successfully resolves the critical challenges of exciton generation, transport, and injection in electroluminescence, achieving highly efficient electroluminescence with high colour purity and tunable spectral properties.
