Maritime hydrogen technology requires completely new solutions, and HAV Hydrogen builds these solutions by combining ship technology expertise acquired over a long period of time with extensive R&D work.

We cooperate with research institutions such as Sintef Ocean and CMR Prototech, are in close dialogue with a large number of hydrogen component suppliers, and, finally, we participate in the maritime hydrogen cluster Arena Ocean Hyway Cluster.


HAV Hydrogen combines its cutting-edge fuel cell technology and hydrogen management expertise with several decades of experience in ship design and the Norwegian offshore industry’s unique understanding of risk.

Hydrogen-based energy systems for ships will enable large ships to sail longer distances with zero emissions. We make this happen by combining technical know-how, ingenuity, and strength of purpose.

The emission of the colourless and odourless hydrogen gas is not harmful to the environment, but the gas is highly flammable and explosive in low concentrations, which constitutes a risk that must be managed. 

All hydrogen installations on ships have undergone extensive risk analyses in cooperation with both the ship’s flag state and the classification society, and will therefore have a safety design that incorporates barriers against all conceivable incidents, and against any impact on material assets and human life and health should an incident nevertheless occur.

Hydrogen has been used on a large scale in the processing industry, as fuel in the space industry and in land-based transportation such as trains and buses. All fuels, be it diesel, coal or even electricity in a battery, have a high energy potential that can be dangerous if the energy is released too quickly and without control. That is also the case with hydrogen. 

Through technological developments, we have found safe ways of harnessing the powers of fossil fuels, and we are now developing the solutions that will ensure that hydrogen can be used safely and in a manner adapted to the specific properties of this particular fuel.


We put together highly reliable, efficient, and serviceable solutions and systems while also taking unknown factors into account.

We use methods adapted from the excellent risk management work carried out on the Norwegian continental shelf. We also have our own FreeCO2ast project, through which our research has generated solutions to how hydrogen systems can better withstand the ship's movement in high seas.
