Samsung E&A, a plant engineering unit of Samsung Group, said Thursday its U.S. subsidiary has secured a 680 billion-won ($475 million) order to build an ammonia plant in the United States, marking its first such deal since its establishment. Samsung E&A America signed an engineering, procurement and fabrication (EPF) contract with Wabash Valley Resources LLC to construct a low-carbon ammonia plant in the state of Indiana by April 2028, the company said in a press release. Once completed, the plant will have an annual production capacity of 500,000 tons of ammonia and will be capable of capturing 1.67 million tons of carbon dioxide, it said. The ammonia produced at the facility will be used as fertilizer on farms across the midwest region of the United States, the company said.
