For hydrogen to gain broad acceptance and adoption – in domestic settings and for new applications beyond current industrial uses – industry and regulators will need to prove the safety case.

DNV carries out safety analysis of hydrogen applications, experiments to obtain knowledge about consequences for full-scale incidents, and offers technical solutions to determine time- and cost-optimal solutions. We set and check requirements for safe and reliable design, construction, and use of hydrogen, deliver risk studies, and develop and support regulatory documentation.

Watch our panel discussion with experts from Northern Gas Networks (NGN), National Grid and DNV, where we debate the key issues for hydrogen safety

Services to energy and maritime industries

  • Full-scale experiments to study leakages and fire and explosion behaviour 
  • Quantitative risk assessments (QRAs) and HAZID studies, for onshore and maritime applications, such as:
    • Transportation and storage assets (hydrogen/natural gas/LNG/CO2)
    • Hydrogen systems and components on board maritime vessels
    • Hydrogen refuelling stations and maritime bunkering systems
    • Validation of fire and explosion models for quantitative risk assessments (QRAs) 
  • Risk-based technology qualification according to DNV Recommended Practice 
  • Development of odorants, metering, and analytical methods
  • Development of guidelines and standards for hydrogen safety and quality
  • Identifying safe limits for hydrogen in natural gas appliances
  • Review of concept designs of hydrogen carriers
  • Alternative design and arrangement analysis, and technology qualification of hydrogen systems onboard vessels.

Classification (maritime)

  • Certification of hydrogen materials and components for maritime vessels
  • Classification of hydrogen carriers and ships using hydrogen as fuel
  • Survey of hydrogen carriers and ships using hydrogen as fuel
  • Approval in Principle (AiP) for hydrogen-fuelled ship installations and hydrogen containment systems.

Testing hydrogen safety on HyStreet

Three ordinary-looking houses built at DNV’s Spadeadam Research and Testing facility are playing a central role in multi-million-dollar tests to prove the safety case for hydrogen.

Handbook for Hydrogen-fuelled Vessels

A consortium of 26 leading companies and associations, led by DNV, has launched the “Handbook for Hydrogen-fuelled Vessels" to address the uncertainties surrounding hydrogen as ship fuel.


DNV is proving the safety case for a switch from natural gas to hydrogen in a domestic setting, as a partner in the H21 programme in the UK.


DNV joined several partners to assess the technical, regulatory and economic feasibility of a hydrogen fuel-cell coastal research vessel, and granted a Conditional Approval in Principle (CAiP).


DNV is investigating hydrogen purity and flame colourization as part of the Hy4Heat programme

DNV to class commissioning service operation vessels prepared for hydrogen operations

At the Nor-Shipping trade fair, DNV signed a classification contract for two new Commissioning Service Operation Vessels (CSOVs), ordered by the Norwegian pure play offshore wind operator Edda Wind. The vessels will be built at Colombo Dockyard in Sri Lanka and are designed for service operations during the commissioning and operation of offshore wind farms and are prepared for hydrogen operations. They are scheduled to be delivered under the Norwegian Flag in January 2024 and July 2024.

Navigator Gas awarded DNV AiP for new ammonia fuelled gas carrier design

Navigator Gas has been awarded a new Approval in Principle (AiP) for an ammonia fuelled gas carrier design from classification society DNV. An industrywide consortium, including MAN Energy solutions, Babcock International, and the Norwegian Maritime Authority (NMA), has collaborated with Navigator Gas to achieve the Approval in Principle (AiP) from DNV. The awarding of the AiP was announced as part of London International Shipping week 2021.

New DNV research highlights 10 energy systems technologies that must work together to meet global decarbonization targets

DNV, the independent assurance and risk management provider, has highlighted how 10 key energy transition technologies are expected to develop, compete, and interact over the next five years if global economies are to meet emissions reduction targets. DNV’s aim is to make an objective and realistic assessment of the status of these technologies and evaluate how they can contribute to the energy transition ahead.
