China’s Sinopec, one of the world’s largest state-owned energy and chemical companies, signed an agreement to to deliver engineering services for ACWA Power in Yanbu, Saudi Arabia, supporting the development of what will be the world’s largest integrated green hydrogen and green ammonia facility in the country, Reuters reported.

The project will harness wind and solar energy to produce about 400,000 metric tons of green hydrogen and 2.8 million tons of green ammonia each year.

Under the agreement, the company’s subsidiary, Sinopec Engineering Group, will handle the front-end engineering design as well as the convertible engineering, procurement, and construction work for the project.

In addition, Sinopec stated that the project is expected to begin commercial operations in 2030, though no financial details were disclosed.

Sinopec has a long-standing presence in Saudi Arabia, most notably through its joint venture with Aramco in the Yanbu-based YASREF refinery, which is now being expanded into a major petrochemicals hub. More recently, the company has taken on large-scale projects including a $1.1 billion gas pipeline contract and an engineering role in the kingdom’s upcoming green hydrogen and ammonia megaproject.
