The brief

Analyst view

• World's largest oil refining conglomerate, state-owned and administered by China's State Council.
• Kuqa in Xinjiang pairs 300 MW solar with 260 MW alkaline electrolysers for 20,000 t/yr green hydrogen.
• Reached 100% full-load operation on all 52 electrolysers in July 2026, achieving design capacity.

Technical approach

As reported

Solar-Powered Electrolysis

Green hydrogen from renewable electricity

300 MW solar powers 260 MW alkaline electrolysers. Water splits into hydrogen and oxygen.

Alkaline Technology

Proven, mature electrolyser type

Potassium hydroxide and nickel electrodes. Cheaper than PEM, tolerant of power swings.

Refinery Integration

Direct hydrogen supply

Hydrogen pipelines to Tahe refinery, replacing fossil-derived hydrogen in oil processing.
