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 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. 

The IEA HIA held a dedicated parallel session at WHEC 2016 on Wednesday 15 June. The IEA HIA Manager and Operating Agents from the following tasks gave presentations:
The 2014 IEA HIA Annual Report Executive Summary provides an overview of progress in the IEA HIA and hydrogen, including our first ever count of Hydrogen Refueling Stations (HRS) around the world. Consult the IEA HIA 2014 Annual Report for updates on the full story from Members, Tasks, Chairmen and Secretariat.

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.
