Inhabitat's Week in Green: Riversimple's hydrogen car and more!
Is the age of the hydrogen car upon us? This week Riversimple announced plans to launch a 250-mpg fuel cell vehicle that's as affordable as a gas-burning car. The craziest part is that the company won't be selling it: Drivers will instead purchase a monthly plan that includes maintenance, insurance and hydrogen fuel. Meanwhile, Lexus unveiled the LC 500h, a 470-horsepower beast that could very well be the sexiest hybrid ever made. And three friends developed one of the craziest-looking vehicles we've ever seen. It's called the Cedar Rocket, and it's the world's fastest electric log car.
easyJet's hybrid plane design has a hydrogen fuel cell inside
Aiming to save the European airline money, oh and the environment, easyJet hopes to trial new hybrid plane designs later this year. We're not talking about a new paint job or minor wing design changes, however: the company wants to embed a hydrogen fuel cell into a new hybrid plane design, with aircraft brakes that absorb energy on landing to be reused, even powering the jet through taxiing without using its engines.
Hydrogen fuel cells give drones 'several hours' of flight time
If we want drones to deliver packages and generally do much, much more than just fly around for a few minutes, they need to be able to last longer. A company called Intelligent Energy says its hydrogen fuel cell-powered range extender can make that happen and give unmanned aerial vehicles the power to fly for several hours instead of just around 20 minutes. The new fuel cell stack is supposed to be incredibly lightweight, so the drones can fly as usual with one strapped to their bodies. It can also apparently shorten the one-to-two-hour-long wait in between flights to just two minutes, since the flying contraptions no longer have to be recharged the traditional way. Unfortunately, the company hasn't announced pricing and availability yet -- and it's still just a prototype -- but we'll keep an eye out for its demonstration at CES 2016 for interested drone owners.
Nanowires help produce hydrogen fuel using sunlight
You ideally want to produce clean hydrogen fuel using clean sources, and Dutch researchers have taken a big step toward making that a practical reality. They've built a solar cell that uses a grid of gallium phosphide nanowires to make hydrogen gas from water. The approach gets a useful yield of about 2.9 percent in lab tests. That may not sound like much, but it's about 10 times more effective than previous techniques and uses 10,000 times less exotic material.
Toyota takes orders for its hydrogen-fueled Mirai on July 20th
If you're fortunate enough to live in one of the California burgs where Toyota will deliver the Mirai this October, you now know just when and where you can pull the trigger. Toyota says that it'll start taking American requests for the hydrogen fuel cell car through its website on July 20th. And we mean only through the website -- dealers will "explore" the $57,000 sale with you and hand over the keys if you commit, but you can't simply walk in and get a vehicle. It's just as well. The automaker only expects to sell 3,000 Mirais in the US by the end of 2017, so you'd be hard-pressed to get one if you had to compete with the same people test-driving Camrys and Priuses.
BMW has a hydrogen-powered 5 Series
Battery-powered EVs are in the spotlight right now, but that doesn't mean car manufacturers aren't looking at alternative fuel sources. At its "Innovation Day" in France, BMW unveiled a prototype 5 Series GT that uses a hydrogen fuel cell to power its electric motor. We've seen the company experiment in this space before -- the Hydrogen 7 used the element to power a combustion engine -- but this is its first complete FCV package. Unlike the Hydrogen 7, which managed roughly 124 miles on hydrogen, the modified 5 Series can easily top 300. With 245 horsepower under the hood it's no slouch either, although we doubt it would keep pace with BMW's electric i8 in a drag race.
Stanford researchers find a cheaper, better way to make hydrogen gas
A team of researchers from Stanford University unveiled an easier and more efficient way to strip hydrogen atoms from water molecules on Thursday. It's still the same electrolysis method that's been in use for years. But instead of using two different kinds of material for the cathode and anode, like conventional electrolysis procedures, Stanford is incorporating a pair of identical nickel-iron oxide catalysts. When a 1.5V current is applied, the system operates at 82 percent efficiency -- many times more than what its conventional equivalent can make with the same charge. It could be precisely the production breakthrough that the hydrogen fuel economy needs to actually take off.
Hydrogen-powered drone will fly for hours at a time
Even the nicer drones you can buy typically last for just minutes in the air, which isn't much help if you're delivering packages or shooting movies. Horizon Unmanned Systems (HUS) thinks it has a solution, however: hydrogen power. Its recently unveiled Hycopter drone runs on a lightweight hydrogen fuel cell that should deliver up to 4 hours of flight time unloaded, and 2.5 hours when it's carrying 2.2 pounds of cargo. That still may not sound like much, but it makes long-distance flights practical -- it's the difference between flying across the city and staying within the neighborhood. HUS won't even fly the Hycopter's prototype until later this year, but patience could well pay off if you're tired of piloting robotic aircraft in half-hour bursts.
Toyota's hydrogen car to sell on just eight lots come October
Toyota's new hydrogen-powered fuel cell vehicle (FCV), dubbed the Mirai, will be hitting dealer lots this October...all eight of them. The car company announced today that only select lots throughout California will actually be taking stock based on their previous advanced technology vehicle sales as well as the relative development of hydrogen infrastructure in their areas. The Mirai starts at $57,500, though with state and federal tax credits you're looking closer to $45,000 (plus free hydrogen for "up to three years"). You can check one out in person at San Francisco Toyota, Roseville Toyota, Stevens Creek Toyota, Toyota of Sunnyvale, Longo Toyota, Toyota Santa Monica, Toyota of Orange and Tustin Toyota. The company plans to produce just 200 units to start though it hopes to sell as many as 3,000 Mirai by the end of 2017.
NASCAR's first hydrogen-powered pace car hits the track
NASCAR may be dominated by gas-guzzling racers, but its pace car this weekend is decidedly kinder to the environment. The motorsport league's Sprint Cup race in Richmond on the 26th (delayed from the 25th due to rain) has Toyota's hydrogen-powered Mirai as its pace car -- the first time a fuel cell car has had that distinction at a NASCAR event. This is largely a publicity stunt to build up hype for the Mirai's Californian launch later this year, but it shows that hydrogen cars have the performance needed to keep up with stock cars during yellow flags. The real challenge will be getting the actual competitors to go green. While there have been hydrogen-fueled race cars before, the odds are that NASCAR and its fans aren't eager to abandon roaring V8s any time soon.
Engadget Daily: Sony announces 'The Interview' release, hydrogen-powered vehicles and more!

What you need to know about hydrogen fuel cell vehicles
Damn the torpedoes (and Teslas)! Two of Japan's biggest automakers are about to make sizable wagers on a different kind of clean fuel tech: hydrogen power. Toyota will launch the $57,500 Mirai fuel cell vehicle (FCV, above) next year, while hydrogen veteran Honda will out a model in 2016. But wait, aren't EVs the last word in green cars? Fuel cell cars are EVs, in a way, but you can fill one up with hydrogen in five minutes rather than waiting hours for a charge. The only way to do that in an electric vehicle (EV) is by swapping the entire battery. So why is there exactly one production FCV available to buy today, but EVs everywhere? That's a tale of efficiency, fuel, pollution and politics.
Research breakthrough could make hydrogen gas an even better green fuel
Toyota might be bringing a commercial hydrogen fuel cell car to roads in 2015, but the fuel still has a few drawbacks -- the major ones being storing and transporting the gas itself. Research from the UK's Science and Technology Facilities Council (STFC) reckons they can solve it using ammonia, which is more secure and less volatile, as the hydrogen delivery method. "Cracking" ammonia offers up one part nitrogen and three parts hydrogen and while the catalysts that do this are typically pricey precious metals, this new research uses two chemical processes at the same time, offering the same results at a much lower cost. According to the research team leader, Professor Bill David: "Our approach is as effective as the best current catalysts but the active material, sodium amide, costs pennies to produce. We can produce hydrogen from ammonia 'on demand' effectively and affordably."
Rohm showcases colorful solid hydrogen-source fuel cell chargers at CEATEC
You know what makes a fuel cell charger in your pocket a little less frightening? Colors! CEATEC mainstay Rohm has arrived back in Japan with a new set of hydrogen-source fuel cell chargers, with the latest prototype lot boasting a litany of new hues that may very well match up with that iPhone 5c you're (presumably) picking up soon. The actual technology used within hasn't changed from last year, but the company is evidently considering the release of such portable chargers for those who'd prefer something a bit less drab. We're told that a fully-fueled pack can keep the average smartphone alive for twice as long as it would otherwise last, but as has become the norm at this show, there's nary a hint of a price / release date.

New hydrogen-making process could make fuel-cell vehicles cleaner than EVs
It'll be about two years yet until you're able to buy a hydrogen-powered vehicle, but one company is already making progress in ensuring those cars will be as gentle on the environment as possible. BASF, the world's largest chemical maker, has come up with a hydrogen-making process that would purportedly cut carbon dioxide emissions in half, making fuel-cell vehicles generally cleaner than EVs. Until now, the holy grail has been hydrogen produced without introducing oxygen, as that would mean avoiding carbon dioxide emissions. The problem is, that's meant cranking up the operating temperature, which means you're using more energy, which means, uh, you're looking at some carbon dioxide emissions. In this new system, though, BASF recycles heat more efficiently so that the company doesn't have to raise the temperature quite so high. Additionally, the company's cooked up some new catalysts it hopes will make the process more cost-efficient. No word on when or where this method will be implemented, but BASF is already hopeful it could be useful in other industries, like oil refinement, which similarly use lots of hydrogen.
GM and Honda team up to produce next-gen fuel cells by 2020
You'd be forgiven for thinking that hydrogen fuel cell cars have vanished when EVs rule the headlines, but GM and Honda haven't forgotten them -- in fact, they've just unveiled a new fuel cell partnership. The automakers are jointly developing next-generation hydrogen systems and storage, using their collective resources to cut costs and accelerate their schedule. If all goes well, the two companies will show "commercially feasible" fuel cell products around 2020. Don't fret if that sounds too distant, however. Honda has already committed to launching an FCX Clarity sequel in 2015, and GM is promising additional fuel cell details at a "later date."
US Navy's Ion Tiger drone leans on liquid hydrogen for longer-lasting spy flight
The US Navy's quieter way to spy, the Ion Tiger, just bested its own 2009 flight record with a key assist from liquid hydrogen. The unmanned aerial vehicle had previously relied on 5000-psi compressed hydrogen for fuel, but for its latest flight test the Naval Research team swapped that out for a new cryogenic tank and delivery system that relies on the liquid stuff; a choice made for the element's increased density. With that one significant change in place, the craft was able to outperform its last endurance run of 26 hours and two minutes by almost double, lasting 48 hours and one minute in a flight made mid-April. Spying: it's not only good for the government, it's good for the environment, too.
Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge
Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below. Zach Honig contributed to this report.
Mercedes slaps sheet of LEDs on the side of an F-Cell, turns car into a chameleon
It's not often that folks want to hide the fact that they're driving a Mercedes, what with plenty of them being among of the finest motorcars on the road. However, as part of a marketing plan to call attention to its zero-emissions F-Cell model, the German marque swathed a side of one in LEDs to give it the ultimate in camouflage. You see, in addition to that makeshift display, a Canon 5D Mark II was mounted on the other side of the car so that video of its surroundings could be shown on the LED bodywork -- rendering the car all but invisible to onlookers, as long as they're staring at the left side, of course. Go ahead, head on down to see the magic of digital camo for yourself in the video after the break.
Microbial fuel cell produces hydrogen from wastewater without wasting energy
Back in 2005, Bruce Logan and his team of Penn State researchers developed a microbial fuel cell capable of converting poop into power. Now, Logan has refined his system to the point where it can produce hydrogen from wastewater or biodegradable organic materials without using a drop of grid electricity, and without emitting even a hint of carbon dioxide. His approach, outlined in the September 19th issue of the Proceedings of the National Academy of Sciences, involves something known as reverse-electrodialysis (RED) -- a process that harvests energy from the ionic discrepancy between fresh and salt water. Logan's bacterial hydrolysis cell (pictured left) features a so-called RED stack that's comprised of alternating positive and negative ion exchange membranes, which it uses to split water molecules into hydrogen and oxygen. Normally, this process would involve about 25 pairs of membranes, but by using RED technology in conjunction with electricity-producing exoelectrogenic bacteria, Penn State's team was able to extract hydrogen with just five membrane pairs. All told, Logan's cells proved to be about 58 to 64 percent energy efficient, while producing between 0.8 to 1.6 cubic meters of hydrogen for every cubic meter of liquid that passed through the system. The researchers' results show that only one percent of that energy was used to pump water through the cells, which are completely carbon neutral, as well. According to Logan, this breakthrough demonstrates that "pure hydrogen gas can efficiently be produced from virtually limitless supplies of seawater and river water and biodegradable organic matter." Somewhere, the US Navy is taking scrupulous notes. Full PR after the break. [Image courtesy of Penn State / Bruce Logan]
