Largest green hydrogen plant in the world

Ningxia Hui region

From PV magazine:

Chinese coal miner Baofeng Energy has announced the start of construction of what it claims will be the world’s largest solar-powered hydrogen plant, in the Ningxia Hui autonomous region of northwest [north-central]China.

The RMB1.4 billion ($199 million) electrolysis project is intended to produce 160 million cubic meters of hydrogen per year plus 80 million cubic meters of oxygen. Baofeng said the use of solar electricity to power the facility would save 254,000 tons of coal consumption annually, leading to a 445,000-ton reduction in carbon emissions.

The project will feature two 10,000m3/hr electrolyzers powered by two 100 MW solar plants plus a 1,000kg/day hydrogenation station and two petrol stations will be converted to also supply natural gas and hydrogen for transport purposes. The solar panels will be installed over wolfberry and alfalfa crops which will generate extra revenue, according to Baofeng.

Work on the project started this month and is slated for completion this year, with hydrogen production to start next year.

However, the company is also going to produce "brown" hydrogen from coal, which is definitely not carbon-neutral:

Baofeng is also working on a coking co-generation plant to produce three million tons of coal-based coke per year, plus 1.2 billion cubic meters of hydrogen.
