The compressed hydrogen carrier H2Neo from Australian Provaris Energy, formerly Global Energy Ventures (GEV), has received design approval from the classification organization American Bureau of Shipping (ABS).
The 26,000 m3 H2Neo compressed hydrogen carrier from Provaris has undergone ABS's evaluation, verification, and approval, making it the first to achieve this certification level.
The approval, a critical milestone, comes after the front-end engineering design (FEED) work is finished.
It demonstrates the compatibility of the H2Neo carrier with the multi-layered hydrogen tank from Provaris.
The company will proceed to the next phase after receiving design approval, which entails building and testing a prototype hydrogen tank and getting ready for ship construction with a chosen shipyard(s).
Early in 2023, the corporation will conduct a shipyard selection and tendering procedure after appointing shipbroker Clarksons.
Provaris' Chief Technical Executive Officer Per Roed said: "The success of our FEED design stage and corresponding approval milestone is the result of extensive design and engineering works by Provaris' team of discipline experts and consultants that have actively contributed to the development of Provaris' innovative H2Neo hydrogen carrier."
"Through our close collaboration with ABS throughout this three-year process, we are confident that our compressed hydrogen carriers can safely and effectively establish the maritime transportation of hydrogen at a time when storage and transport remain key to unlocking markets with ambitions for hydrogen imports at scale from 2026," he remarked.
ABS' Senior Vice President – Global Engineering and Technology, Patrick Ryan, added: "ABS recognizes the potential that hydrogen shows in supporting a sustainable, lower carbon future. Safe and efficient storage and transportation of hydrogen at sea will be critical to the development and viability of the global hydrogen value chain. We have been working closely with Provaris, initially granting AIP in 2021 and subsequently reviewing their comprehensive FEED-level package for the H2Neo."
Provaris began work on a project to create a compressed hydrogen carrier in October 2020. In 2021, ABS granted Provaris permission in principle (AiP) for two classes of environmentally friendly compressed hydrogen carriers, the H2Neo (26,000 m3) and the H2Max (120,000 m3 capacity).
Two large-diameter cylindrical tanks with a maximum permissible operating pressure (MAOP) of 250 bar, one in each cargo hold on the port and starboard sides of the vessel, define the H2Neo design.
The hydrogen is transported at ambient temperatures to prevent boil-off and cargo losses and eliminate the requirement for insulation and energy-intensive refrigeration throughout the voyage. According to the business, the cargo containment system's design pressure rating has been established to be 250 bar under these circumstances.
Provaris claims that the H2Neo is in line with regional hydrogen supply quantities that will be accessible starting in 2026, and the H2Max, slated for 2030, can support a single export operation with a sizable capacity of 950,000 tonnes per year.
The company is now developing floating storage barge methods to create equivalent volume storage using compressed hydrogen ship designs.
