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 Berlin Transport Authoriity, the Berliner Verkehrsbetriebe  (BVG)  is preparing the acquisition of 50 more hydrogen buses this year to be delivered next year. With 14 hydrogen buses already in daily service the BVG saved  130 t CO2 since 2007. The BVG is operating also 5 CNG buses, but as the costs of natural gas has gone up no acquisition of CNG buses have been communicated.
