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.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.
