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

The EU-27 urban development Ministers met in Marseille to discuss how different policies can contribute to sustainable urban development. As a follow-up to the May 2007 Leipzig Charter on integrated sustainable urban development, ministers committed to building a reference framework for sustainable cities. The framework would outline the general principles of a sustainable city: an integrated approach of all public policies and all levels based on interaction of environmental, economic and social sectors.  As for the general architecture of the reference framework, ministers called on different stakeholders to set up focus groups to coordinate joint assessment of the local sustainable development and identify areas for improvement. The ministers think that technical assistance and professional training could be considered for these focus groups in order to ensure capitalisation and dissemination of the results. According to the French EU Presidency, the final architecture and specifications of the reference framework would be jointly developed by a high-level group made up of representatives of member states, EU institutions, local authority networks, professional associations and the civil society and by a cities work group set up as part of the URBACT project.  The EHA has asked a meeting the URBACT coordinator for sustainable transport to present the role of hydrogen in clean urban transport.
