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

Mercedes-Benz is working on a hydrogen fuel cell powertrain that is expected to go into the just-introduced GLC-Class crossover. Mercedes admits it is working on the technology and has the goal of a 600-kilometer range (373 miles), with a refueling time of three minutes. The company has not said, however, what vehicle its hydrogen tech will go in.

The compact crossover is the rumored candidate partly because Mercedes feels the cost of the powertrain means it only makes commercial sense in more expensive vehicles. Autocar says we could see the GLC F-Cell introduced at the Frankfurt Motor Show in the fall of 2017 before it is offered for lease or sale in 2018. At the moment the price is figured to come in around 50,000 pounds ($75,950 US). The price of a conventional GLC in the UK right now is 34,950 pounds ($53,089 US). The Toyota Mirai is on sale in the UK currently with a retail price of 66,000 pounds ($100,254 US).
