Japan wants to boost fuel-cell numbers 100x by 2020

How many hydrogen refueling stations will Japan need? Can each station handle 250 fuel-cell vehicles? They can in the Japanese government's new plans for hydrogen fuel-cell vehicle growth and station deployment throughout the country. With Prime Minister Shinzo Abe continuing to trumpet fuel cells as the advanced powertrain of the future, the government says the number of fuel-cell vehicle on its roads will multiply by 100 within the next four years, according to the Japan Times. Specifically, Japan, which is home to about 400 fuel-cell vehicles today, hopes to have 40,000 by 2020 and a whopping 800,000 by 2030. More importantly, Japan has 80 stations either in operation or slated to be deployed soon, and hopes to double that number by the end of the decade. For perspective's sake, the US has about two-dozen publicly accessible hydrogen fuel cell stations today, according to US Department of Energy. The newer ones are can dispense 100 kilogram a day, which can fuel 20-25 cars a day. Japanese automakers Honda and Toyota appear to be trying to do their parts in the H2 plan. Earlier this month, Honda started leasing its Clarity fuel-cell vehicle in Japan and is planning to bring them to California later in the year. The vehicle, which is priced at about $68,000 in Japan, is said to be able to travel about 466 miles on a full hydrogen tank, per the more lenient Japanese driving cycle (roughly 300 miles on the US scale). Honda will start production at a rate of 200 vehicles a year. With skin in the game, though, Honda indicated late last year that it was frustrated with what it said was the slow pace of fuel-cell station deployment in Japan, according to Bloomberg News. Honda was collaborating with hydrogen supply company Iwatani Corp. on what they called a "Smart Hydrogen Station," though that concept was in its testing phase as of last December. The Mirai also started sales in Japan and debuted in limited numbers in California last year. Last fall, Toyota set a rather lofty goal of selling 30,000 fuel-cell vehicles a year by 2020 as part of its Toyota Environmental Challenge 2050.

Toyota and Mazda set to expand partnership

Toyota and Mazda are already teaming up for the Scion iA and Mazda2, but that partnership might just be the beginning. Reuters reports the two Japanese companies could expand their work together, with Toyota chipping in its experience with both fuel cells and plug-in-hybrid tech, and Mazda contributing its know-how in regards to its Skyactiv line of engines. The report cites a pair of unnamed sources that are "not authorized to discuss the matter publicly." The move, on the surface, is certainly appealing for both parties. Mazda has very little experience with hybrids (remember the Ford-rebadged Tribute Hybrid?), let alone something as advanced as a fuel-cell vehicle. Teaming with Toyota, arguably the world's greatest hybrid manufacturer, would give it a serious leg up. For the Japanese giant, meanwhile, a partnership with Mazda could expand the economy of scale for the Mirai FCV's tech, while Skyactiv engines would do well in replacing the base engines in cars like the Corolla, Camry, and RAV4. What are your thoughts? Would an expanded partnership between Toyota and Mazda make sense? Can you think of any drawbacks? Have your say in Comments.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
