Hyundai shipbuilding group leads hydrogen production using floating wind farm
South Korean shipbuilding group Hyundai will lead a joint project to produce green hydrogen from electricity produced by a large floating wind farm to be built off the port city of Ulsan in the south-eastern part of the country. southeast, with full government support.
The shipbuilding group said its affiliates have signed a memorandum of understanding with the Ulsan National Institute of Science and Technology (UNIST), Korea East-West Power and other partners involved in the project. floating wind farm run by Ulsan.
Green hydrogen is produced from water from renewable energy. Hyundai Heavy Industries will develop a large-scale electrolysis plant that produces green hydrogen from seawater using electricity produced by floating wind turbines. Korea East-West, a Power, a public electricity supplier, produces electricity and develops a business model, while UNIST demonstrates a green hydrogen power system.
They will demonstrate a 100 megawatt pilot plant by 2025 and a 1.2 gigawatt plant by 2030. In a government-sponsored project, some 36 trillion won ($ 32 billion) will be spent by 2030 for the construction of a huge offshore wind complex off the coast of Ulsan. produce 6 GW of electricity usable by 5.76 million households.
The first phase of construction of an offshore gas platform in wind farm facilities by 2025 with an injection of more than 1.4 trillion won has passed a preliminary feasibility study conducted by the Korea Development Institute (KDI) , a national think tank, announcing the start of South Korea’s first floating wind farm project.
At a ceremony on May 6 in Ulsan, President Moon Jae-in described floating wind farms as South Korea’s future growth engine and a “shortcut” to achieving energy conversion and carbon neutrality because they can reduce 9.3 million tonnes of carbon dioxide per year. “Ulsan will become the world’s best hydrogen city in 2030 and lead South Korea’s carbon neutrality.”
“Ulsan’s floating offshore wind farm will become an oil field on the sea and open up the future of a power plant,” Moon said, adding that South Korea could produce 84,000 tons of green hydrogen using 20 % of electricity produced by wind. agricultural complex in Ulsan in 2030.
In March, the shipbuilding group unveiled a new business roadmap to establish a hydrogen value chain by 2030 by combining the infrastructure and technological competitiveness of subsidiaries. The group will accelerate the development of hydrogen transport vessels and create hydrogen fuel-powered vessels.
Hyundai Oilbank, a refining arm of the shipbuilding group, will produce blue hydrogen and use it for desulfurization plants or sell it as fuel for vehicles and power generation. As part of a March 3 deal with Saudi Aramco, the refiner agreed to use Aramco’s ammonia as fuel for liquefied natural gas boilers. Ammonia is considered a more suitable ship fuel for the post-carbon era due to its stability in supply and relatively easy storage and transport.
Ammonia, which is a combination of nitrogen and hydrogen, has been highlighted as the main resource for establishing fuel cell-based infrastructure. A UNIST team led by Kim Gun-tae, professor of energy and chemical engineering, has developed a method to produce green hydrogen by breaking down liquid ammonia into electricity using foam electrodes. porous nickel. The surface of the nickel foam electrodes has platinum catalyst particles applied evenly for high efficiency.
Kim said the method uses less electricity than hydrogen by electrolysis. “If the high efficiency electrodes presented in this study are applied to electrolytic ammonia processes, the commercialization of the hydrogen production technology will be faster.”
