Provaris initiates the production process for a prototype 250-bar hydrogen storage tank.

Provaris Energy, headquartered in Australia, has commenced the manufacturing process for a prototype 250-bar hydrogen storage tank intended for use on its upcoming carrier vessels.

The fabrication process was initiated at Provaris’ European facility located in Fiskå, Norway. The H2Neo tank will incorporate Provaris’ innovative layered design, featuring a combination of carbon steel and stainless steel liners. Sized at 2.5 meters in diameter and 9 meters in length, the tank is designed to accommodate 650 kilograms of hydrogen at 250 bars of pressure.

Upon completion, rigorous testing will be conducted to validate the tank’s design integrity, including fatigue and over-pressurization tests simulating 25 years of operational conditions.

The full-scale H2Neo tank is projected to store 430 tonnes of compressed hydrogen onboard vessels for extended transportation routes.

Provaris conducted an internal study revealing that using compressed hydrogen for storage and transportation consumes 20% less energy compared to liquefaction methods and over 40% less than ammonia. Additionally, the company asserts that compression technology can result in up to a 20% reduction in regional delivery costs over distances of 2,000 nautical miles and an annual volume of 100,000 tonnes.
