International Energy Agency – Hydrogen Implementing Agreement (IEA-HIA)


Task 39: Hydrogen in Maritime Transport


As the primary means of transportation, shipping contributes to emissions of CO2, SOx and NOx. Various environmental regulations are imposed on shipping to reduce adverse health and environmental impacts of shipping. In addition, noise may have an effect on ocean life. Healthy oceans are one of the main challenges of the future.

There is a strong focus among policy makers, ship owners and other stakeholders to work towards safer, greener and smarter shipping. The International Energy Agency – Hydrogen Implementing Agreement (IEA-HIA) Task 39, under the direction of Prof. Ingrid Schjølberg at NTNU Oceans, will support this work.

The Overall goal for the task is to provide knowhow on the use of hydrogen and fuel cells in the maritime, evaluate concepts and initiate research and demonstration projects. This will be achieved by creating an exclusive network of suppliers of hydrogen and fuel cells, shipping companies, advisory and assurance and research institutions. The ambition is to contribute to research within the area, be a technology monitor for ongoing activities as well as contributing to a global regulatory framework. 






IEA-HIA Task 39 consists of four subtasks: (i) Technology Overview, (ii) New Concepts, (iii) Safety and Regulations, and (iv) Demonstration.




Expert Meetings

Two expert meetings are held each year, where actors from academia, research institutes, industry and regulatory bodies gather to discuss advances in use of hydrogen and fuel cells in shipping.

Expert meetings in 2017

  • NTNU hosted the first expert meeting on 13–14 February 2017 in Oslo, Norway. 40 participants from 15 countries and 29 institutions joined the meeting.
  • TU Delft hosted the second expert meeting on 26–27 September 2017 in Delft, the Netherlands. 42 participants from 11 countries and 31 institutions joined the meeting. During this meeting, white papers and conference papers were planned. The meeting ended with a tour in TU Delft labs.
