On August 9, according to Caixin News, HD Hyundai Marine, South Korea's largest shipbuilding group, plans to speed up the development of ammonia-fueled fuel engines and go public as early as September. Last month, the company completed the acquisition of STX Heavy Industries, gaining access to its environmentally friendly engine technology. With increasing global restrictions on carbon emissions, reducing carbon emissions from ships has become a key issue. Compared to other fuels, ammonia does not produce carbon emissions when burned, which can effectively reduce greenhouse gas emissions and may become one of the decarbonization transformation directions of the marine power industry.
