China’s onshore giant PetroChina has started building a groundbreaking solar-to-hydrogen project in the country’s northwestern Gansu province, marking the beginning of a series of similar projects planned for deployment on its existing fields across China.

Scheduled for completion by the end of next year, the project is set to include building three water alkaline electrolysers, each with capacity of 1000 cubic metres per hour, alongside two proton-exchange membrane hydrogen production stations, collectively able to yield 2100 tonnes per annum of green hydrogen.
