SEOUL, January 06 (AJP) - Samsung's engineering unit Samsung E&A has begun construction of a low-carbon ammonia plant in the United States under the Wabash project.

The firm said on Tuesday that it held a groundbreaking ceremony the previous day for the U.S. Wabash Low-Carbon Ammonia Project at the Hay-Adams hotel in Washington. The company signed an engineering, procurement and fabrication contract with Wabash Valley Resources in October valued at about 680 billion won ($475 million), and is targeting completion of the plant in 2029.

Around 70 people attended the event, including South Korea’s Minister of Land, Infrastructure and Transport Kim Yun-deok, Samsung E&A President Namgung Hong, U.S. Deputy Secretary of Energy James P. Danly, and Simon Greenshields, chairman of Wabash Valley Resources.

The facility will be built in the West Terre Haute area of Indiana and is designed to produce 500,000 tons of ammonia annually while capturing about 1.67 million tons of carbon dioxide each year.

Samsung E&A described the project as a national-level initiative supported by a fund involving the U.S. Department of Energy and South Korea’s Ministry of Land, Infrastructure and Transport, as well as the Ministry of Climate, Energy and Environment.

Samsung E&A said it plans to apply its ammonia-plant experience and advanced technologies, including digital transformation, artificial intelligence, automation and modular construction. It will also work closely with the project owner and technology licensor Honeywell UOP.
