KHI develops cargo tank technology for large LH 2 carrier
Kawasaki Heavy Industries, Ltd.
(KHI) has completed technologicaldevelopment for a cargo containment
system (CCS) to be used in large liquefied hydrogen (LH 2) carriers. This
project was carried out under the New
Energy and Industrial Technology
Development Organization of Japan(NEDO) subsidy program “Technology Development Project for Buildinga Hydrogen Society, Technology Development for Using Hydrogen Energy on a Large Scale, Developmentof Large-Scale Transport and Storage
Equipment, and Export and Import
Terminal Equipment for Liquefied
Hydrogen.” As part of this project,
Kawasaki designed and built a testtank to be used to verify the performance of a CCS for large liquefiedhydrogen carriers, and conductedverification tests.
Large-volume marine transportation of hydrogen requires that thehydrogen must be cooled to minus
253oC to be liquefied and reduced to
1/800 of its gaseous-state volume, andthese low-temperature conditions reliably maintained for long periods. To
achieve this, Kawasaki developed a

new distinctive
CCS, the CC61H
type, for largescale liquefiedhydrogen carriers. The CCS
uses a sphericaldesign to minimize the outersurface area relative to the inner
capacity and minimize heat ingress.
The CCS also features a double-shellstructure that provides high-performance, two-step thermal insulation.
The test tank designed based on the
CC61H type is similar in size to theplanned CCS for use in large liquefied hydrogen carriers, each of which
will be equipped with four 40,000m3
tanks for a total cargo capacity of
160,000m3. The structural dimensions of the test tank components,
such as the thickness of structuralmembers and thermal insulation materials, were adapted to match current
vessel designs. Moreover, the integrity of the new structure was verified, including assembly, welding, andworkability of insulation. During theAn image

final step of the development process,Kawasaki carried out gas replacement, cooling, and heat-up tests using the test tank. Efficient gas replacement was confirmed for the internal
space of a large tank using inert gas,
and insulation performance wasachieved as planned.
Kawasaki will continue work onlarge liquefied hydrogen carriers forcommercial operations, in line with aliquefied hydrogen supply chain commercialization demonstration projectrunning through 2030. Through these
efforts, Kawasaki will contribute to
the promotion of hydrogen energy
use and the achievement of carbon
neutrality.
