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

Last month saw the opening of the upgraded 700 bar hydrogen filling station in Berlin with the filling of the fuel cell car Hydro-Gen4 by GM/Opel. For the first time at a public station an infrared interface was used for data communication between filling station and vehicle. Ramping up the station to 700 bar was done by the Linde Group: the basic plant on the ground of the public bus depot Heerstrasse has been there for a while already; it comprises a cooling system (Ultra Low Cold Fill) for precooling of the hydrogen to shorten the filling time. The station can fill up vehicles with 5 kg hydrogen gas in three minutes. More info at www.linde-gas.com
