We’re making the future of hydrogen accessible through simple and efficient compressed hydrogen.
Choice of compression enables simplicity and efficiency throughout the value chain, leading to lower delivered costs.

We are developing a proprietary gaseous hydrogen containment tank for carriers and storage solutions.
The H2NeoTM (450-tonne) and H2MaxTM (2,000-tonne) capacity carriers and the H2LeoTM storage barge (300 - 600 tonne capacity range) designs are advancing through to final marine classification and approvals, along with critical safety studies. H2NeoTM is based on a standard MR tanker with two integrated tanks to store hydrogen at 250 bar MAOP. US Patent has been granted on the cargo containment system and integration into the hull.
Co-operation with global shipping company Kawasaki Kisen Kaisha, Ltd. (“K” LINE) to accelerate Provaris’ commercialisation of our hydrogen carriers. In 2025, we entered a MOU with “K” LINE marking a significant step toward the commercialisation of Provaris’ compressed hydrogen shipping and offshore storage solutions. “K” LINE will offer technical, commercial, and operational assistance using its accumulated knowledge and global shipping expertise to aid Provaris’ development of its hydrogen transport and storage model.

Our strategy is to be the first-mover in regional supply of green hydrogen to support industrial decarbonisation
“Compression for the marine transportation of hydrogen is the simplest and most cost-effective option for regional distances. The entire value chain from renewable generation to delivery to the customer needs to be analysed to provide the true picture – exactly what Provaris’ ‘Hydrogen Marine Transport Comparison Report’ and “Concept Design Study (Compression)” have achieved.”

Why did compression beat ammonia as an efficient low-cost carrier of green hydrogen?
The outcomes demonstrate the efficiency and cost benefits of compressed hydrogen produced in Norway delivered to Rotterdam from a 540MW capacity reservation export site, producing 87,000 tpa of hydrogen, for export using Provaris’ H2Neo carriers over a distance of 1,000 Nm.
50%
Energy efficiency across the entire production and supply chain (generation, production and delivery). Compression delivered 50% more gaseous hydrogen volume compared to ammonia + cracking back to hydrogen.

Energy efficiency across the entire production and supply chain (generation, production and delivery). Compression delivered 50% more gaseous hydrogen volume compared to ammonia + cracking back to hydrogen.
20%
Based on an IRR of 12% (all equity, pre-tax), over a 20 year supply term, compressed hydrogen showed a 20% lower delivered hydrogen price to the customer compared to ammonia + cracking back to hydrogen.

Price
20%
The compressed hydrogen production and supply chain delivered a 20% lower capital cost intensity on a Euro per kg of hydrogen delivered basis compared to ammonia + cracking back to hydrogen.
Capex
5–10x
Compressed hydrogen production and supply chain provides the developer with a material increase in the net-back price of H2 and project NPV, compared to ammonia + cracking back to hydrogen.

Compressed Hydrogen
An energy efficient bulk-scale carrier for green hydrogen
In September 2024, Provaris announced the completion of its ‘Concept Design Study’ for bulk-scale hydrogen export and import compression facilities. The findings reaffirmed the low energy use and low capital of Provaris’ compressed hydrogen supply chain for regional marine transport of hydrogen in gaseous form.
The results support hydrogen export feasibility studies being undertaken for sites identified in Norway and the Nordics along with import site locations such as Port of Rotterdam as part of our collaboration with Global Energy Solutions.
The comparison between compressed hydrogen vs ammonia supply chains is illustrated below, for both delivered volume and delivered price to the customer, in addition to the simplicity of import infrastructure required for gaseous hydrogen.

FjordH2
Provaris is pleased to announce a joint development with Norwegian Hydrogen AS, to establish the 270 MW FjordH2 project, located at Ørskog in the Ålesund municipality. FjordH2 will utilise Provaris’ innovative compressed hydrogen storage (H2Leo) and marine carriers (H2Neo) to become one of the largest production facilities in the Nordic region to support the REPowerEU’s green hydrogen import demand by 2030, contributing to a zero-emission future.
