New Energies, new possibilities

豊田中央研究所は、固体高分子形燃料電池の触媒層を構成するアイオノマーの含水率を、短時間で正確かつ定量的に測定する手法を開発した。中性子小角散乱法を用いて、乾燥状態と加湿状態の試料を比較分析することで、含水率を算出した。

Sungrow Hydrogen has launched China’s first green hydrogen project utilizing both PEM and alkaline electrolysers in joint operation, marking a milestone in the nation’s green hydrogen production capabilities. Located in Hubei province, the Daye Green Power project combines renewable energy storage in underground caverns with advanced electrolyser technology to optimize efficiency and energy consumption, positioning itself as a global benchmark.

Sungrow Hydrogen has announced the commencement of operations for China’s first green hydrogen project utilizing both PEM (Proton Exchange Membrane) and alkaline electrolysers in joint operation. Located in Daye city, Hubei province, the 27 MW facility is a collaboration with Daye Green Power and represents a significant leap forward in China’s hydrogen energy landscape.

The facility is equipped with five 5MW alkaline electrolysers and one 2MW PEM electrolyser, all provided by Sungrow. This hybrid system, combining the cost efficiency and stability of alkaline electrolysers with the dynamic response and flexible power adaptation of PEM technology, aims to optimize hydrogen production efficiency while reducing energy consumption. Sungrow’s spokesperson highlighted that the combined operation of these systems would enhance overall dynamic performance, broaden the load regulation range, and serve as a technical validation of their approach.

The $476.2 million (CNY 3.44 billion) project is situated on an abandoned mine site and features 300 MW of co-located solar panels. It also incorporates an AI-powered smart management system that helps optimize renewable power matching and ensures real-time safety control.

Hydrogen produced at the facility will be stored both in above-ground spherical tanks and in an underground cavern, which is a first for China. This underground hydrogen storage solution, designed to store surplus hydrogen, is a 30-meter-long cavern with a diameter of five meters. Sungrow claims that this innovative storage method sets a new benchmark for future green hydrogen developments globally.

The plant is expected to produce 1,800 tons of green hydrogen annually, which will be used to fuel hydrogen buses and industrial vehicles, such as dump trucks and excavators, in the local mining industry. The city of Daye is well known for its coal, iron, and copper mines, and the hydrogen project is set to integrate seamlessly with the region’s long-standing smelting industry. As part of the project’s broader goals, Sungrow Hydrogen has also worked on initiatives like the Shanxi Yulin Coal Chemical Industry Base and remains a key player in advancing China’s hydrogen economy through its innovative technologies and strategic projects.
