Australian start-up Provaris Energy reports that it is making further progress in its design efforts for a compressed hydrogen gas carrier. The company is developing one of several concepts within the shipping industry that are planned to meet future requirements for transporting large quantities of hydrogen gas. Provaris reports that it is targeting 2026 for delivery of the ship.

In the final step of the project, Provaris reports that it has signed a Memorandum of Understanding with Northern Marine Management, a member of the Stena AB group of companies, to provide technical expertise to the project. Under the terms of the agreement, the companies will enter into a technical partnership to support the ongoing engineering and development program of H2Neo, the compressed hydrogen (GH2) carrier concept. Northern Marine will provide its expertise in naval architecture, ship engineering, regulatory and maritime quality assurance and ship management to support the development and commercialization of the H2Neo vessel.

Items to be covered will include the development of detailed designs to obtain class and flag approval for the ship. In the second phase, they would assist in shipyard selection, contracting for the newbuild, certification of conformity and oversight of the newbuild. Provaris and Northern Marine will also explore commercial opportunities for a fleet of H2Neo carriers. The agreement also provides that Northern Marine will provide ship management services on a contract basis in the future.

“The GH2 Carrier design team continues to make excellent progress on the final design package for discussions with shipyards, an important milestone to refine our build cost and timeline and feed into the ongoing project studies,” said Martin Carolan, Managing Director & CEO of Provaris.

The company recently reported that it expects the engineering design package for the ship to be available for delivery in June. They said it is currently 70 percent complete after conducting gas dispersion, fire and explosion safety studies with ABS Consultants. The aim is to share the completed packages with shipyards for building design and capital cost estimates and class societies as part of the building permit. The company is aiming for planning permission in mid-2023.

“The H2Neo engineering and design is now sufficiently advanced to begin discussions with Class for test design and construction approval,” said Per Roed, Provaris Chief Technology Officer. “We are now also integrating port infrastructure designs for our supply chain discussions with ports in Asia and more recently in Europe.”

As the project evolves, the company is also collaborating with class societies, beginning pre-engineering and concept design for port infrastructure solutions required for compressed hydrogen import and export terminals. Ongoing discussions include the possibility of an unloading dock with Singapore and the assessment of existing marine facilities at Port Melville in the Tiwi Islands. The company said it will also develop concept designs for a storage barge that could be used as an eventual supply chain extension.
