  • GEV has commenced the development of a pilot-scale C-H2 Ship with a cargo capacity of 430 tonnes of hydrogen
  • The addition of a 430-tonne capacity hydrogen ship will:

Align with the scale, timeline, and downstream market opportunities for green hydrogen projects under consideration, both in the Asia Pacific and Europe.

  • Reduce overall development risk, capital, and construction schedule, and

Enable GEV to achieve its target of an operating fleet of C-H2 vessels by mid 2020’s.

Martin Carolan, Managing Director and CEO commented: “GEV’s design and development strategy for the 2,000-tonne ship proved that large commercial scale C-H2 ships are possible and paved the way for the development of a pilot-scale version. The 430-tonne ship is an ideal size to meet the needs of the current emerging H2 marine transportation industry and will ensure we establish ourselves in the marine transportation of green hydrogen.

Extensive marketing of our C-H2 solution has provided valuable insights into both the scale of supply and demand for green hydrogen in the mid-late 2020’s. A pilot-scale ship will be complementary to partner discussions and GEV’s target to develop a fully integrated green hydrogen supply chain from Northern Australia. This includes GEV’s own renewable energy project to produce green hydrogen based on a specific customer use case, delivered with our own C-H2 ships.

Blending is an attractive source of near-term demand for hydrogen at low blend volumes due to low incremental costs and aligns with C-H2’s modular approach for production scale-up. The scale of a 430t ship can alleviate the additional infrastructure requirements that a liquefaction or ammonia project will require to deliver pure hydrogen gas to the end-user. Regions with aspirations to develop a low-carbon hydrogen economy are likely to turn to grid injection as a means of cultivating a market and stimulating investment into supply.”1

GEV has assembled a team with a successful track record of achieving AIP and the expertise to take the C-H2 ship through to Full Class Approvals with ABS by the end of 2022. More details will be provided on the key milestones in the coming quarters.”

DEVELOPMENT OF A 430 TONNE PILOT SHIP FOR OPERATION MID-2020’s

The Company is pleased to advise shareholders it has made the appointments of Capilano Maritime, C-FER Technologies, Tekkara Project Services, and American Bureau of Shipping for the engineering, design and safety analysis required to achieve Class  Approvals. The development of a 430-tonne capacity C-H2 Ship will leverage the successful design and approvals received for the 2,000-tonne capacity ship in March 2021.

Whilst the achievement of AIP remains a rigorous process to satisfy engineering, regulatory and safety requirements for this new vessel, the Company will benefit from a reduction in the amount of time and cost to the schedule in order to target AIP for the end of Q3 2021, and to ultimately target Full Class Approvals by late 2022.

The work program which commenced on June 1, 2021, will also focus on material selection,  welding specifications, and prototype design for the required ABS testing program, which will occur in 2022. Refer to Figure 1 below for an indicative timeline for the 430-tonne C-H2 ship.

Strategical reasons to move forward with a pilot-scale C-H2 ship, include:

  1. GEV’s analysis of the near-term supply and demand for green hydrogen in the 2025-2030 timeframe, making this a world first for the marine transport of green hydrogen at scale.
  2. The 430-tonne containment system fits within a Handymax sized vessel envelope which reduces the development time and cost, maintains a practical ship draft of 9 metres, whilst also optimising the scale of the ship to match hydrogen production volumes.
  • A smaller capacity ship aligns with opportunities under review for European and Asia Pacific demand centres for downstream applications such as grid injection (blending) and fuel
  1. Aligns with GEV’s own renewable energy and hydrogen export project of up to 1.5 GW of renewable energy, matched with a scaled production and delivery of green hydrogen from Northern Australia to Asia.

THE KEY SPECIFICATIONS OF THE 430 TONNE C-H2 SHIP

The proprietary design for the containment system is made up of two large circular 12m diameter tanks, contained within the hull of the ship, that will store ambient temperature hydrogen at an operating pressure of 250 bar and will have a combined containment capacity of 430 tonnes of hydrogen.

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 steel’s molecular structure and over time can cause the steel to suffer from embrittlement.  Embrittlement is managed in our design by providing a liner such as stainless steel that prevents the steel structure from becoming damaged by the hydrogen.
