The South Korean government has given the go-ahead for a consortium of industry leaders to develop a liquid hydrogen tank for ships, paving the way for hydrogen to be used in shipping.
As a result of a joint effort between KRISO, Hylium Industries, POSCO, and KSOE, AIP has been granted by the Korean register to the four companies involved in developing this critical technology.
There are two types of maritime liquid hydrogen fuel tanks that have been certified by the Korean Register, one made of 316L stainless steel and the other made of 316HN stainless steel.
Liquid hydrogen storage containers that need to be kept at a temperature of -253°C can be made using 316L stainless steel, which is a common austenitic stainless steel.
A new steel developed by POSCO, 316HN stainless steel, further solves the hydrogen embrittlement problem that is common in the production of liquid hydrogen storage containers.
KRISO, POSCO, KSOE, and Hylium Industries will continue to promote the commercialization of liquid hydrogen-powered ships through active advancement of developed technologies as the development of the ship continues.
