Topsoe technology selected for ACWA green ammonia plant

Topsoe says that it has been selected as the ammonia technology licensor for ACWA’s Yanbu Green Hydrogen Project in the Kingdom of Saudi Arabia. The process will enable green hydrogen from the Yanbu Project to be converted into ammonia. Topsoe will also deliver engineering, proprietary equipment and catalysts to Sinopec and Tecnicas Reunidas, who have jointly been awarded the front-end engineering design (FEED) contract.

Yassir Ghiyati, CCO at Topsoe, said: “We are happy to expand our collaboration with ACWA on their impressive project. Green ammonia plays a critical role in reducing emissions from energy-intensive industries and long-distance transportation. We need to deploy decarbonisation solutions on a global scale, and ACWA’s project will be able to deliver a strong contribution.”

The Yanbu Green Ammonia Project is a large-scale development for gigawatt-scale green hydrogen. The licensing agreement covers the first mega-scale green ammonia units in Yanbu, with a capacity of 2,700 t/d (890,000 t/a), as well as an interest to replicate the scheme in subsequent units. Topsoe says that its dynamic ammonia process will enable the ramping up/down of ammonia production bidirectionally at a rate of at least 3% per minute in response to the fluctuating supply of hydrogen to the ammonia plant, as well as a significant reduction in capital expenditure and operational expenditure since hydrogen storage systems can be reduced substantially, or otherwise eliminated.
