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

Om March 30, 2008  the Council of the EU adopted a Directive (COM 2007/475) to promote energy efficient road transport vehicles in  public fleets. The Directive aims to stimulate the market for clean and efficient vehicles and to prompt developments and investments by the industry. Increased sales will help reduce costs through economies of scale and will result in progressive improvement in the energy and environmental performance of the whole vehicle fleet. The new measures extend to all purchases of road transport vehicles by public authorities or by transport operators charged with public service obligations. The Directive requires that energy and environmental impacts linked to the operation of vehicles over their whole lifetime are taken into account in purchase decisions. These lifetime impacts of vehicles shall include at least energy consumption, CO2 emissions and emissions of the regulated pollutants of NOx (nitrogen oxide), NMHC (non-methane hydrocarbons) and particulate matter. Purchasers may also consider other environmental impacts. Two options are offered to meet the requirements: setting technical specifications for energy and environmental performance, or including energy and environmental impacts as award criteria in the purchasing procedure.If the impacts are monetised for inclusion in the purchasing decision, common rules shall be followed, as defined in the Directive, for calculating the lifetime costs linked to the operation of vehicles. To facilitate the implementation process, the Commission has launched today a very comprehensive website on clean and energy efficient vehicles. It includes a legislation guide, a lifetime calculator, information on joint procurement and references to Community funded projects in the field.
