Inner Mongolia Dengkou Integrated Demonstration Project for Wind and Solar Power-to-Hydrogen
Key Projects in Bayannur City | Major Hydrogen Energy Demonstration Project in Inner Mongolia Autonomous Region
Project Overview

The integrated wind-solar hydrogen production demonstration project in Dengkou, Inner Mongolia, is located in Dengkou County, Bayannur City, Inner Mongolia. Developed and invested by Shanghai Shanyao New Energy Development Co., Ltd., with a total investment of 31.21 billion yuan, the project aims to build an integrated hydrogen production base that combines wind power, photovoltaics, energy storage, electrolytic hydrogen production, and hydrogen storage. It has an annual green hydrogen output of 20,000 tons.
