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

“A few years ago, the price was at about 1,500 euros per kilowatt hour for a lithium ion battery. In the midterm we should be at a level of 400 euros,” Herbert Kohler, head of e-drive and future mobility at Daimler AG, told AutomotiveNews Europe. Kohler said he expected an even bigger price decrease for fuel cells. “By 2015, we think a fuel cell car will not cost more than a four-cylinder diesel hybrid that meets the Euro 6 emissions standard,” Kohler said.He added that he expects EVs to be more expensive than fuel cells in less than five years. That is why Daimler is working fast to get more fuel cell cars on the road. “By 2013-2014, we want to bring a four-digit-number of fuel cell vehicles to market,” Kohlersaid. Daimler has spent the past year running a test fleet of its B-class fuel cells cars. The company plans to launch a second-generation of the car when it starts building the next generationA- and B-class models on its new front-wheel drive architecture in 2013-2014. Kohler added that Daimler may make fuel cell versions of the C- and E-class luxury models”For gas-producers in general, fuel-cells are a very profitable business-case” Kohler added. “I expect that there will be a network of 1,000 fuel-stations in Germany alone in the midterm.This means that you will find a fuel-station for your fuel cell within 30 kilometers.”  (source Autonews)
