China's first high-altitude photovoltaic hydrogen storage project starts operation

(ECNS)-- China's first high-altitude photovoltaic hydrogen storage project entered operation in Delingha, northwest China’s Qinghai Province on Tuesday. This project can generate 2.2 billion kilowatt-hours of green electricity a year, serving 2 million households annually

Huadian Delingha, or Huadian Qinghai Delingha 1 million kilowatt light storage and 3-megawatt photovoltaic hydrogen production project in full, is the first batch of large-scale wind and solar base project in China and the first attempt in high-altitude areas focusing on deserts, plateaus, and wastelands. It aims to extend the hydrogen energy industry chain and achieve the consumption of green electricity and hydrogen by establishing an integrated technology system.

Photovoltaic hydrogen storage refers to the process of producing and storing hydrogen when there is abundant solar power but no access to the grid. Stored hydrogen gas will be converted into electricity through various methods, such as internal combustion engines and fuel cells, and delivered to the power grid.

The project will save 543,900 tons of coal and reduce carbon dioxide emissions by 1.48 million tons per year with hydrogen production of 600 cubic meters per hour.
