Global Energy Ventures Ltd. provide the following update on the development of a new compressed hydrogen ship (C-H2 Ship) to transport the zero-carbon fuel of the future. GEV's unique C-H2 ship has a large hydrogen carrying capacity of 2,000 tonnes. This vessel will be key to establishing an economic and energy efficient sea-link between hydrogen producers and customers. The application of a C-H2 supply chain will be applicable in multiple markets globally that are now establishing hydrogen economies. The key specifications of the C-H2 ship are as follows: The proprietary design for the containment system is made up of two large (20 metre diameter) tanks, contained within the hull of the ship, that will store ambient temperature hydrogen at an operating pressure of 3,600 psi (250 bar) and will have a combined storage capacity of 2,000 tonnes of hydrogen. The design of the C-H2 ship will also allow for the evaluation of smaller capacity ships for demonstration or pilot scale export projects. One of the key considerations in designing a steel tank for storing hydrogen, is that the hydrogen molecule is so small it can enter the steels molecular structure and over time can cause the steel to suffer from embrittlement. A practical way to avoid hydrogen embrittlement is to provide a liner that prevents migration of hydrogen into the steel. Technical requirements for such a large tank mean that it needs to be constructed in layers. Stainless steel will be used as the innermost layer, being resistant to hydrogen embrittlement, with six surrounding layers of ductile high-strength alloy steel to meet strength and fatigue requirements. One significant advantage of a tank made from multiple discrete layers is that should a crack form in one layer it will not naturally proceed through to the adjacent layer. This greatly improves the safety of the tank. With the rapid advancements in both marinized fuel cells and hydrogen internal combustion engines, GEV intends to fuel the ship with hydrogen available from the containment systems, providing a `zero-carbon' shipping solution.
