Welcome to the IEA HIA

With a 35 + year operating history and significant accomplishments to its credit, the International Energy Agency (IEA) Hydrogen Implementing Agreement (HIA) is a unique leader in the management of coordinated hydrogen research, development and demonstration activities on a global basis.

Through the creation and conduct of nearly forty annexes or tasks, the IEA HIA has facilitated and managed a comprehensive range of Research, Development & Demonstration (R, D&D) and analysis programs among its Contracting Party (country and international organizations) and Sponsor (industry, PPP, non-profit) Members.


The IEA HIA belongs to the IEA Energy Technology Network, a framework created by the IEA

The Climate Change Studio interviewed Mary-Rose de Valladares, IEA HIA Manager, at COP22 on 3 November during the recent United Nations Framework for Climate Change Conference (UNFCCC) in Marrakesh, Morocco.

The IEA HIA Fall-Winter 2016/2017 Newsletter is up now. It has been a big year for the implementing agreement. Highlights include the approval of Task 39 – Maritime, participation in the June 2016 World Hydrogen Energy Conference and the recent accession of China to the agreement. We’re also pleased to announce a new highlight to our newsletter – a summary count of global hydrogen refueling stations (HRS). The current number of "early market stations” stands at over 200!

The IEA HIA is happy to announce: People’s Republic of China Becomes a Member of the International Energy Agency Hydrogen Implementing Agreement (IEA HIA). China has elected to participate in IEA HIA Task 32 – Hydrogen-Based Energy Storage. Two institutions, the Dalian Institute for Chemical Physics (DICP) of Dalian and the General Research Institute for Nonferrous Metals (GRINM) of Beijing, will represent China on the IEA HIA Executive Committee.

TASK 29: Distributed and Community Hydrogen (DISCO H2) has produced a Final Report on Subtask 3 - Model Concept Development. The goal of Task 29 Subtask 3  was to develop replicable and scalable models for three types of distributed hydrogen systems: urban, island/rural, and industrial/commercial. 

Task 28 Report: This report from IEA HIA Task 28 concludes that the main barrier to large-scale introduction of hydrogen and Fuel Cell Electric Vehicles (FCEVs) is market development rather than technology development.  FCEVs are technically ready for commercialization.  In the last decade, significant progress has been made toward commercializing hydrogen as an alternative fuel for transport.  Hydrogen delivery technologies and pathways --particularly Hydrogen Refueling Stations [HRSs] -- have been demonstrated and tested and are ready for scale-up to build initial networks.

Global Hydrogen Resource Study, final report of Task 30 – Global Hydrogen Systems Analysis Subtask A – Global Hydrogen Resource Analysis:  This report developed the Global Pathways Analysis Tool (GPAT) to calculate least-cost pathways for hydrogen supply in eight participating countries:  Denmark, France, Germany, Japan, Norway, Spain, Sweden and the United States.  

IEA Technolgy Roadmap, Hydrogen and Fuel Cells: On 30 June the IEA launched the Technology Roadmap for Hydrogen and Fuel Cells, the last roadmap in the series mandated by the G8 in 2008.  The IEA HIA supported preparation of the roadmap from start to finish, hosting the second in the series of three geography –based workshops dedicated to its development.
