Hydrogen is colorless, odorless, and non-toxic substance; the lightest and smallest of the elements. Hydrogen is recognized as a flexible carrier of renewable energy: it can be produced from any energy source, and also converted into various forms. The main challenges with hydrogen are related to its production and storage. Global annual hydrogen demand is below 2% of the world energy production. Furthermore, most of the hydrogen today is produced from fossil sources, 50% from natural gas, 30% as a by-product from the petroleum refining, 18% from coal, and only 4% by water electrolysis.

Advanced Motor Fuels is one of the International Energy Agency’s (IEA) transportation related Technology Collaboration Programmes (TCP). AMF TCP has not been working directly on hydrogen as motor fuel, however, hydrogen based elecro-fuels are handled in Annexes of chemically similar fossil fuels (diesel, methane, methanol). (AMF, www.iea-amf.org).

Hydrogen TCP focuses on the management of coordinated hydrogen research, development and demonstration activities on a global basis (http://ieahydrogen.org/). Recent work of Hydrogen TCP covers:

• Task 37 - Hydrogen Safety
• Task 38 - Power-To-Hydrogen and Hydrogen-To-X
• Task 39 - Hydrogen in Marine Applications
• Task 40 - Energy Storage and conversion based on hydrogen
• Task 41 - Data and Modelling (Sub-Task C – Cooperation with ETSAP)
