China generates 99.9% pure 'green hydrogen' as world's largest H2 producer
The world's largest green hydrogen project, which generates hydrogen from solar and wind renewables without emitting carbon dioxide, produced its first batch of "green hydrogen" on Thursday in Ordos, Inner Mongolia Autonomous Region in north China.
This new project is anticipated to yield an annual production of 30,000 tonnes of green hydrogen and 240,000 tonnes of green oxygen, resulting in a reduction of approximately 1.43 million tonnes of carbon dioxide emissions per year. To put it in perspective, this reduction is equivalent to planting 825,000 trees. China Petroleum & Chemical Corporation (Sinopec), the country's largest hydrogen producer, provided this information.
Making full advantage of its bountiful wind and solar resources, Ordos is an ideal location for the green project. The initiative combines two clean energy sources: solar power and hydrogen. It employs an electrolysis device that utilizes green electricity generated from solar energy to decompose water into hydrogen and oxygen.
The project marks Sinopec's second green hydrogen project, following the one in Kuqa City, northwest China's Xinjiang Uygur Autonomous Region, the construction of which began in 2021. Liu Shiliang, general manager of Sinopec Nova, told China Media Group (CMG) that the Kuqa plant went into operation on Friday with hydrogen purity reaching 99.9 percent.
The hydrogen production capacity electrolyzed water of the Kuqa plant is 20,000 tonnes per year, and the hydrogen storage capacity is 210,000 standard cubic meters, with the hydrogen transmission capacity reaching 28,000 standard cubic meters per hour.
The green hydrogen and green oxygen produced by the project will be transported through pipelines to a coal-deep processing project. This will replace the existing coal-to-hydrogen process, promoting the clean and low-carbon transformation of coal-powered chemical products. Xu Zhendong, the executive director of Sinopec Star Petroleum's Inner Mongolia branch, shared this information with CMG.
By exploring a pollution-free and zero-energy approach, this new hydrogen production model addresses a crucial issue of power balance and consumption in the grid's high proportion of renewable energy connections.
Tech-driven production
Green hydrogen has emerged as a crucial component in the development of the hydrogen industry, offering a pathway towards a low-carbon and sustainable future, according to an expert who spoke at the World Hydrogen Technology Convention 2023 last month.
