100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

In 2007 the International Energy Agency and the IPHE conducted a series of workshops (Detroit, Paris and Shanghai) on Hydrogen infrastructure development. The EHA presented local hydrogen developments in Europe at the Paris workshop. The hydrogen activities at  the secretariat of the IEA are currently being reviewed. The EHA gave an update on its activities and referred to its insight in national developments through its 14 national member associations and in regional local activities as the EHA office is currently hosting  the secretariat of Regions and Municipalities Partnership HyER (formerly HyRaMP).
