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

EHA is following the progress of the 3 B-Class F-Cell  vehicles that were launched for their trip around the world. The journey started on the 29th of January 2011 in Stuttgart Germany, and in 125 days the vehicles will have traveled around the world and a distance of 30,000 km. The editor and others involved in the journey are frequently updating the public on their trip. Their journal not only lets us know about the vehicles but gives an interesting story to the people and places that are visited around the world.  The latest news shows the vehicles are in New Orleans Louisiana in the USA.
