In 2024, a groundbreaking 200 MW wind power-to-hydrogen combined operation demonstration project was initiated in Boli County, Heilongjiang, China. This project, powered by green hydrogen and facilitated by Yantai Dongde Hydrogen Energy Technology Co., marked a milestone in sustainable energy production in the region. The project not only addressed the energy needs of the area but also played a crucial role in the comprehensive revitalization of north-east China. By leveraging a diaphragm compressor from Yantai Dongde, the project was able to overcome the harsh climatic conditions typical of cold regions, establishing a benchmark for future green hydrogen projects in similar environments. Once operational, the project is expected to deliver 620,000 megawatt hours of clean electricity annually, leading to significant reduction in standard coal usage and carbon dioxide emissions. This success story paves the way for a more sustainable future by showcasing the integration of renewable energy sources and hydrogen production, promoting a greener and more integrated development approach.
