Hyosung to construct world’s largest liquid hydrogen plant in South Korea


South Korean conglomerate Hyosung announced its plans to build the largest liquid hydrogen plant in the world.

With an ambition to build a hydrogen economy, Hyosung has partnered with Linde Group, a service provider for industrial gases.

The two companies have also signed a memorandum of understanding (MoU) at Hyosung headquarters in Mapo, Seoul, South Korea.

Hyosung has also agreed to invest KRW300bn ($246.1m) until 2022 under the joint enterprise to create a value chain that claims to cover everything from setup and operation of liquid hydrogen production, transport and recharging facilities.

As per the MoU, the two companies will form a joint venture later this year and invest in the construction of a liquid hydrogen plant on 30,000m² of an area within the site of Hyosung Yongyeon plant in Ulsan, with an annual capacity of 13,000 tons of liquid hydrogen. The capacity is expected to enough to fuel 100,000 sedans.

The two companies claim that when completed, the plant will be the single largest liquid hydrogen manufacturing facility in the world. The groundbreaking of the facility is expected to take place in the first quarter of next year and will be production-ready in 2022.

Hyosung chairman Cho Hyun-joon said: “Hydrogen is an eco-friendly energy source that can change existing carbon-centred economic structure. Its possibilities are endless.

“The point of liquid hydrogen business sought by Hyosung is to store and transport hydrogen efficiently and safely. Investment this time will play a big role in invigorating the ecology of domestic hydrogen industry.”

The new plant is expected to produce liquid hydrogen by using Linde’s hydrogen liquefaction technology and system to byproduct hydrogen produced by Hyosung Chemical Yongyeon Plant.

The technology liquefies hydrogen in a high-pressure state of gas and Linde is claimed to possess the most advanced technology in hydrogen liquefaction and production.

The companies also plan to develop a liquid-hydrogen recharging infrastructure during the time plant’s construction is completed. They aspire to set up nearly 120 hydrogen recharging station, including 50 new and 70 enlarged stations to fuel liquid hydrogen in key points across South Korea.
