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.

2015 Toyota Camry

Every car has its definitive year. Whether it be the Chevrolet Corvette, the Ford Mustang, or yes, even the ubiquitous Toyota Camry, 10.2 million of which have been sold since 1983, every car has its year. For the Camry, that year was 1992. With son-of-Lexus styling, a clear sense of purpose and a parent company that had hit its stride as the purveyor of faultlessly reliable family transportation devices, the Camry got its legs in 1992. It's a car that even your mom is likely to remember, even if she never owned one herself.
The Camry you see here represents the closest Toyota has come to emulating the magic formula that made the 1992 model the stuff of legends. Compared to the 2014 model, some 2000 of the car's 6,000 parts are new, most of them involving things you can see or touch (on the outside, for example, only the roof carries over from 2014).
It's not a full redesign, but nevertheless it's a stunning development considering the predecessor upon which it's based only survived two model years. That's a testament to both the hyper-competitive nature of the family sedan segment and the lukewarm critical response that the outgoing car garnered. But that's in the past now - after driving this 2015 model, we suspect the new car's changes will be thorough enough to continue pulling in new customers by the hundreds of thousands each year for the foreseeable future.

Toyota hydrogen vehicle visits CES, on sale in US in 2015

If there was ever any doubt that Toyota loves hydrogen vehicles, just listen to some of what Bob Carter, senior vice president of automotive operations for Toyota Motor Sales, USA, said today at the Consumer Electronics Show (CES) in Las Vegas: "Fuel cell electric vehicles will be in our future sooner than many people believe, and in much greater numbers than anyone expected." "Hydrogen works beautifully with oxygen to create water and electricity and nothing more." "This [hydrogen] infrastructure thing is going to happen." "I believe what I'm going to tell you about today is going to change our world." Sounds like love is in the air. In all seriousness, Toyota is incredibly bullish on the future of hydrogen as a part of the automotive landscape, and is now gearing up for the 2015 launch of its hydrogen sedan. The concept version of the car was shown for the first time at the Tokyo Motor Show last fall and is making its North American debut at CES today, alongside the still-under-camo engineering prototype. The reasons for Toyota's hydrogen confidence? The debut vehicle is supposed to be a "reasonably priced" car that has a range of 300 miles and a refueling time of about five minutes. Carter highlighted the engineering work that Toyota has done over the past decades to get the fuel cell system downsized while upping power output to over 100 kW. He also said the vehicle will have carry enough energy to power a house for a week, so company engineers are working on an export power supply device. The H2 Toyota sedan will start sales in California (the only state in the US where there are currently any hydrogen stations) next year. The automaker is working with the University of California Irvine's Advanced Power and Energy Program (APEP) to figure out where to build the next series of public hydrogen fueling stations. Today there are ten, but the model Toyota is using "is based on the assumption that owners want to reach a refueling station within 6-minutes" and shows that 68 stations would be able to serve around 10,000 hydrogen vehicles.
