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 will launch 200  series produced B-Class F-Cell eletric car with a fuel cell  this Spring in Europe and US. The B-Class F-Cell has a range of about 400 kilometers or 248 miles, said Mercedes-Benz. That means it can travel twice as far as the Mercedes-Benz A-Class F-Cell.

“[The B-Class F-Cell] is some 40 percent smaller than the system in the A-Class F-Cell from 2004, but develops 30 percent more power while consuming 30 percent less fuel,” Daimler  said in a statement. The B-Class F-Cell bundles a compact fuel cell stack, a lithium-ion battery, three 700-bar tanks for the hydrogen and lightweight 136-horsepower drive motor at the front axle.

The B-Class also “boasts outstanding cold-start capability down to minus 25 degrees Celsius,” said the automaker. “The system features a new humidification system consisting of hollow fibers that ensures, unlike with the first-generation fuel cell, that water no longer freezes in the stack, a characteristic that used to impair cold-start capability,” Mercedes-Benz said. It noted that, even at low temperatures, the B-Class F-Cell “starts just as quickly as the very latest diesel engine.”

The design of the B-Class F-Cell includes what Mercedes-Benz calls a “sandwich floor,” which means key components for the electric drive with fuel cells are in the vehicle underbody. This helps to conserve space in the cabin. “In the event of a crash, safety valves close the hydrogen supply lines to the fuel cell and decouple the tanks from the other system components,” it said. “Even after a serious accident, the hydrogen poses no risk whatsoever.”
