Provaris Energy has launched H2Leo, a seaborne hydrogen compression storage technology.
The technology is designed to complement the company’s existing compressed hydrogen transportation solution and aims to address the challenge of storing hydrogen, which is a key barrier to its use as a base load fuel in the global energy market.
H2Leo has a storage capacity of between 300 to 600 tonnes of hydrogen, which can be expanded to up to 2,000 tonnes of storage. The American Bureau of Shipping (ABS) has provided ‘Approval In Principal’ for the H2Leo storage solution, paving the way for Provaris Energy to demonstrate the effectiveness of its technology to project partners and regulatory bodies.
The company expects a capital cost of between US$200,000 to US$300,000 per tonne for the H2Leo, which is significantly cheaper than onshore storage solutions. The technology is expected to become available in 2025.
Provaris Energy’s H2Leo is a modular, flexible storage solution that can provide buffer storage in export and import locations, thus reducing the total cost of supply within a compressed hydrogen supply chain. The technology is a natural extension of the company’s compressed hydrogen IP and aims to enable greater flexibility and optimisation within PV1’s hydrogen projects.
H2Leo is being developed in parallel with the H2Neo carrier, which is expected to undergo prototype testing and final class approval later this year.
The launch of H2Leo is a significant step towards the decarbonisation of the energy industry and efforts to replace hydrocarbon-based fuels with hydrogen-based fuels. The technology has the potential to contribute to the growth of the hydrogen economy by enabling a cost-effective, environmentally friendly solution for hydrogen storage.
Overall, Provaris Energy’s H2Leo technology is a promising innovation in the hydrogen storage space and is expected to contribute significantly to the development of a sustainable, hydrogen-based energy economy.
