World’s First Electric Car Ferry Recharges in 10 Minutes | Wired.com
The world’s first battery electric car ferry is under development in Norway. It’s capable of carrying 120 cars and 360 passengers, and it can fully recharge in just 10 minutes.

Called ZeroCat, the 260-foot ferry will enter passenger service in 2015 on a route between Lavik and Oppedal. The ferry’s electric powertrain was designed by Norwegian shipyard Fjellstrand with battery technology from Siemens, and it will be run by ferry operator Norled.

Instead of a 2,000-hp diesel engine — which powers the current ferry and sucks up over 264,000 gallons of fuel each year — ZeroCat features an 800 kW battery that weighs 11 tons and drives two screws. Though the battery is quite heavy, the ship only weighs half as much as a conventional catamaran ferry, thanks to twin hulls made of aluminum. Those hulls are a slim design, which further increases efficiency, with Siemens estimating the ferry will need only 400 kW to cruise at 10 knots.

Norway opens world’s first osmotic power plant

Norway opened on Tuesday the world’s first osmotic power plant, which produces emissions-free electricity by mixing fresh water and sea water through a special membrane.
State-owned utility Statkraft’s prototype plant, which for now will produce a tiny 2 kilowatts to 4 kilowatts of power or enough to run a coffee machine, will enable Statkraft to test and develop the technology needed to drive down production costs.
The plant is driven by osmosis that naturally draws fresh water across a membrane and toward the seawater side. This creates higher pressure on the sea water side, driving a turbine and producing electricity.
