The Indian engineering firm’s RENU vertical signed a memorandum of understanding (MOU) with the Saudi power generation major for the renewables and grid scope of the Yanbu Green Ammonia Project.

The scope includes solar PV, wind, and battery energy storage systems, along with substations and transmission lines that will power the 4.4GW electrolysis facility and ammonia conversion.

The facility, planned to be built in Yanbu Industrial City, is set to use 10GW of wind and solar power to produce 2.5 million tonnes of green ammonia per year for export to key markets like Europe.

ACWA has already contracted Técnicas Reunidas and Sinopec Guangzhou Engineering to conduct a 10-month engineering study for the project, with plans to bring the first phase online in 2030.

It would represent the largest green hydrogen project in the world, with double the capacity of the under-construction 2.2GW Neom plant – also in Saudi Arabia.

“By developing and exporting green ammonia, we aim to support international markets in their decarbonisation efforts and pave the way for a cleaner, more sustainable world,” said ACWA CEO Marco Arcelli.

ACWA has also signed MOUs with Edison, TotalEnergies, Zhero Europe and EnBW to explore European demand for large-scale imports.
