The world's first fuel cell car sharing program launches in Germany

As EVs become increasingly mainstream, they seem to have found a natural home in carsharing services. BlueIndy has left its mark on Indianapolis, Ford has been testing its own EV sharing programs, Japan and China have seen their share of programs pop up, electric carsharing is helping low-income neighborhoods in Los Angeles, and more models continue to emerge. On the flip side, Car2go made news recently when it pulled EVs from its fleet in San Diego. Absent from the carsharing scene, though, have been hydrogen fuel cell vehicles. But even that is changing. In Munich, Germany, industrial gases company (think hydrogen) Linde has launched BeeZero, a carsharing service comprised completely of fuel cell vehicles. The fleet is made up of Hyundai Tucson Fuel Cell crossovers (called the ix35 Fuel Cell in Europe). It's the first hydrogen-powered carsharing service in the world, and Bavaria just happens to be a hub for hydrogen research and technology. Beezero, a new subsidiary of Linde, begins public service this summer with a fleet of 50 Tucson Fuel Cells. It offers users on-demand access to zero-emissions driving, but without the range limitations of battery electric vehicles. These H2-powered Hyundais can travel over 370 miles on a single tank, offering more flexibility to travel to the surrounding areas. If users want to visit the nearby lakes or mountains, they'll also have room to cart their gear with them. Drivers will be able to reserve a car online or through a smartphone app, and vehicles will be available in various zones in and around the city of Munich. As for the hydrogen used to fuel the fleet, Linde creates it from sustainable sources, promising carbon-neutral voyages. While the public gets access to hydrogen-powered mobility, Linde gets to learn from the experience. "We expect to gain valuable information from day-to-day fleet operations which we will use to further develop our hydrogen technologies and to help expand the hydrogen infrastructure," says Linde Executive Board member Dr. Christian Bruch. "BeeZero synergises two mobility trends that are gaining a lot of ground at the moment – car sharing and zero emissions – and will bring the benefits of fuel cell technology to a wider group of potential users."

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

Hyundai previews Brand N performance division

Hyundai has slowly created a presence for its N performance sub-brand since launching the name on the i20 WRC in late 2013, but so far the company has limited the badge to rally cars and concepts. A recent video suggests the moniker might reach the road soon. While Brand N isn't well known yet, Hyundai takes development of its performance credentials quite seriously. The company's European Technical Center at the Nurburgring is handling an increasing amount of the work, and former BMW M GmbH chief engineer Albert Biermann leads the way. He also provides narration for this clip. Beyond the camouflaged hatchback, some of Hyundai's other high-speed machines also make an appearance here. The i20 WRC plays in the dirt a little, but the big star is the wild RM15 concept. Based on the Veloster, it sports a mid-engine, 296-horsepower 2.0-liter turbocharged four-cylinder driving the rear wheels. The wide-body coupe looks great running around the 'Ring, too. Hopefully it indicates how far Brand N intends to go. Related Video:
