Sungrow Hydrogen has launched production at a pioneering green hydrogen project in Daye, Hubei province, China, featuring a 200 Nm3/h PEM electrolyzer and 1,000 Nm3/h alkaline electrolyzers. Described as the world’s largest of its kind, the project combines the cost-effectiveness of alkaline electrolyzers with the rapid response of PEM systems, enhancing efficiency and reducing energy use. Sungrow Hydrogen stated: “The dual-tech combines alkaline electrolyzers’ low cost with PEM electrolyzers’ fast response, boosting efficiency and cutting energy consumption.” The facility employs AI to optimize renewable energy integration and ensure real-time safety, while introducing an innovative underground hydrogen storage system using repurposed abandoned mines.

In a separate development, HNO International, a U.S.-based company, has partnered with Zhuhai Topower New Energy in China to pilot its Scalable Hydrogen Energy Platform (Shep). The collaboration focuses on deploying modular, cost-effective hydrogen production and refueling sites across a Chinese province. HNO International’s CEO, Paul Mueller, said: “This partnership marks a significant step in expanding our Shep technology, enabling scalable and sustainable hydrogen infrastructure in key markets.” The initiative aims to support the growth of hydrogen-based energy solutions in China’s renewable energy sector.

In the United Kingdom, the government has introduced legislation permitting hydrogen-fueled construction and agricultural machinery to operate on public roads. This expands existing regulations that already allow hydrogen-powered cars, buses, and trucks on UK highways, facilitating the adoption of hydrogen technology in diverse sectors. A UK Department for Transport official stated: “This measure supports our commitment to cleaner energy by enabling hydrogen-powered machinery to contribute to sustainable infrastructure and agriculture.”

Additionally, Estonia-based Elcogen has signed a non-exclusive memorandum of understanding with Swiss company Casale to collaborate on green ammonia and Power-to-X (P2X) projects. The partnership explores integrating Elcogen’s solid oxide electrolysis stack and module technology into Casale’s plants for global P2X applications. Elcogen’s chief technology officer, Martin N?mm, said: “Under this MoU, we aim to leverage our solid oxide technology, which is on track to achieve cost parity with PEM and alkaline systems, to drive innovation in green ammonia and other sustainable energy solutions.”

These initiatives reflect global efforts to advance green hydrogen and renewable energy technologies. From China’s innovative hydrogen production and storage to international collaborations and supportive UK policies, these developments contribute to sustainable energy systems, supporting cleaner fuel alternatives and reducing reliance on fossil fuels across various industries.
