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

Task 29: Distributed and Community Hydrogen Energy (DISCO-H2) has produced a Subtask 4 Report: Replicability and Market Readiness of the SixCase Study TechnologiesSubtask 4 assesses the market readiness of each of the projects under a framework developed by the Task participants by drawing on ST2 and ST3 results and additional analysis to draw market readiness conclusions across the six projects.

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.
