CB&I, McDermott's storage business line, and Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) have signed a MoU for a feasibility study of a large liquid hydrogen (LH₂) carrier including an LH₂ storage tank design.

The ability to ship large quantities of H₂ across the ocean is an increasing need to help countries, like South Korea, achieve carbon reduction goals in a H₂ economy. CB&I and DSME bring unique expertise to the study. CB&I will evaluate its LH₂ storage tank design for ocean-going ships and DSME will investigate and develop the ship's general design to install the LH₂ storage tank. The output of the feasibility study is expected to contribute to the future design of a large-scale LH₂ carrier.

"The development of LH₂ storage for ocean-bound vessels is essential to South Korea's focus on a carbon-neutral environment," said Cesar Canals, Senior Vice President of CB&I. "Our expertise in designing and building field-erected pressure spheres for LH₂ storage is a perfect combination with DSME's technical excellence."

CB&I spheres can store LH₂ at temperatures of minus -423°F, and the company is nearing completion of the world's largest LH₂ sphere in Cape Canaveral, Florida, U.S. Their history in this field spans more than 60 years.
