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.

Aging Prius, dropping gas prices putting hurt on hybrid, EV sales

"As Prius represents by far the biggest chunk of the hybrid marketplace, where Prius goes, the segment goes," - Ed Kim, Autopacific
Fuel prices in the US have been tumbling for the last several weeks, with the average price of a gallon of gas at $3.120 as of October 20, according to the US Energy Information Administration. That price reflects a serious recent drop from $3.299 on October 6. Reports have even suggested that those low numbers might not change for a little while, perhaps as long as years. While drivers certainly love paying less at the pump, the change may be hurting the market for more fuel-efficient models, including the Toyota Prius.

DoJ fines Japanese parts firms $740M in massive automotive price-fixing scandal

Nine Japanese suppliers have pleaded guilty in US court over charges of price fixing in the automotive parts industry, resulting in the Department of Justice doling out a total of $740 million of fines, according to a report from Bloomberg. The scandal, which has resulted in General Motors, Ford, Toyota and Chrysler spending up to $5 billion on inflated parts and driving up prices on 25 million vehicles has sent the DoJ hustling into investigations. "The conduct this investigation uncovered involved more than a dozen separate conspiracies aimed at the U.S. economy," Attorney General Eric Holder (pictured above) said during yesterday's press conference.
As the investigation stands, the DoJ has issued $1.6 billion in fines against 20 companies and 21 individual executives, with 17 of the execs headed to prison. Deputy Assistant Attorney General Scott Hammond said, "The breadth of the conspiracies brought to light today are as egregious as they are pervasive. They involve more than a dozen separate conspiracies operating independently but all sharing in common that they targeted US automotive manufacturers."
Big-name suppliers indicted in the investigation include Mitsubishi Electric, Mitsubishi Heavy Industries, Hitachi Automotive and Mitsuba Corporation. A list of fines and other corporations named in the investigation is available at Bloomberg.
