Provaris Energy moves forward with hydrogen carrier projects

ASX-listed Provaris Energy said a package for a new compressed hydrogen carrier is expected to be completed in June, with approval to build the vessel expected in 2023.

Provaris, formerly called Global Energy Ventures or GEV, also said preliminary engineering and conceptual design of the port infrastructure needed to import and export compressed hydrogen is also progressing.

Provaris Managing Director and CEO, Martin Carolan, said: “The GH2 carrier design team continues to make excellent progress on the final design package for shipyard discussions, an important step in refining our costs and our construction schedule and inform ongoing project studies. progress.”

Mr Carolan also said Provaris’ management team recently traveled to Europe and the UK to market the company’s compressed hydrogen system, receiving an “encouraging” response, given its focus. delivery of 2026.

“With demand in Europe for import solutions from 2024-2026, interest in transmission solutions has increased given the focus on energy security and new gas infrastructure requiring approvals for imports of gases needed to demonstrate hydrogen capability,” he said.

Specialized Compressed Hydrogen Carrier

Provaris said its design team and consultants continue to advance the contract’s detailed design package (phase, which is now 70% complete and on track for final delivery in June 2022.

The company said it shared design packages of completed works with shipyards for construction schedule and capital cost estimates, as well as with class societies as part of shipyard approval. construction stage scheduled for mid-2023.

Packages include hull design optimization (speed-power, structural steel assessments and intact and damaged stability), finite element modeling, onboard safety systems, general arrangement drawings and a vessel outline specification.

Provaris Chief Technology Officer Per Roed said H2Neo’s engineering and design has now progressed far enough to begin discussions with the class for test design and build approval.

“We are also now incorporating port infrastructure designs for our supply chain discussions with ports in Asia and more recently in Europe,” he said.

Class approvals

Provaris engaged ABS Consulting for the gas dispersion, fire and explosion safety studies necessary to enable Class to verify the vessel safety issues surrounding its operation, particularly with respect to the fuel storage tanks. hydrogen and cargo management.

The company said discussions with class companies, including the American Bureau of Shipping, were underway on the curriculum required for engineering, risk and safety studies, and testing to gain approval for construction in 2023.

Port designs for compressed hydrogen

Provaris said it is making progress in designing concepts for the export and import of hydrogen to places including Asia and Europe. A basic design is expected to be adaptable to multiple locations, with site-specific access and regulatory requirements a key requirement for customization.

Provaris engaged Paaras Marine Solutions, a Singapore-based marine structural engineering company, to develop and evaluate port systems for loading and unloading compressed hydrogen using Provaris GH2 carriers

Paaras is to develop a concept for an offloading marine jetty facility in Singapore, which will include onshore adjoining jetty systems and an offshore facility with an undersea pipeline connecting to the onshore distribution network.

The engineering firm will also assess existing marine facilities at Port Melville on the Tiwi Islands to accommodate compressed hydrogen carriers. The company will also develop a concept for storing compressed hydrogen on barges, depending on the need for intermittent supply or redundancy in the supply chain.

The conceptual designs will be included in the ongoing feasibility studies for Tiwi H2 and HyEnergy, as well as the analysis of compressed hydrogen with ongoing port operators in Europe.
