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
WALLINGFORD, Conn. — The Hyundai Tucson fuel-cell car is exceptionally quiet even among the near-silent electric cars with the same load space as the production Tucson, and 265 miles of range. This is promoted by Proton Onsite, a EHA member which provides solar power, hydrogen stations and fuel cells systems among other energy sources and materials processing.
 Hyundai talks about this fuel-cell Tucson as the first “mass-produced” hydrogen car said spokesman Derek Joyce: it means that it’s produced on a spur line at the factory in Korea.  1,000 hydrogen Tucsons will be built by the end of 2015 and especially, construction of hydrogen stations. Right now there is a grand total of nine in California (with three more set to open), and one each in South Carolina and Connecticut.

The first Tucson was delivered in June to customer Timothy Bush in Tustin, California. and some cars have gone to Europe (the Tucson is a global model), including a few to fleet customers in Copenhagen.

The Sun Hydro hydrogen pump is operated by fuel-cell specialist Proton OnSite, and it’s solar powered, part of a network envisioned by owner (and Lumber Liquidators honcho) Tom Sullivan. The East Coast hydrogen highway has been delayed, but a second station is now going through approvals in Braintree, Massachusetts.
Refueling the Tucson took only a few minutes. Anyone used to gas stations could learn the technique in a snap — the only challenge is ensuring a positive, no-leak connection.
The Tucson has regenerative braking like the battery electric it closely resembles, and an onboard gauge shows when the car is charging or using power. Otherwise, there’s not much to give the car away as fuel-cell powered.
