Foshan is charging ahead with hydrogen energy development.

Public buses, logistics vehicles, street sweepers - even garbage trucks across Foshan are going hydrogen. This clean energy shift is driving the city's sustainable transport revolution.

This is Foshan's largest biogas-to-hydrogen plant. Since 2023, it's produced 2,200 tons of hydrogen annually - enough to power about 800 households each year.

We collect food waste from restaurants and homes, processing it through anaerobic digestion to create biogas - the raw material for our hydrogen production. Our steam reforming technology then transforms this waste into clean energy.

The process: First, organic waste becomes biogas through anaerobic digestion. Next, carbon-hydrogen reactions convert this into a gas mixture. Finally, catalytic purification extracts pure hydrogen - all without creating new carbon emissions.

Why is this considered 'green hydrogen'?

Gao Tongle

Because we use renewable biogas as our raw material. The entire process creates no additional carbon emissions - that's what makes it truly green.

This is waste-to-energy at its best. They're transforming the city's kitchen waste into valuable resources - fertilizer, biodiesel, and now hydrogen fuel - powering Foshan's clean energy future.
