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.

Toyota says president, chairman of scandal-hit Daihatsu unit to step down

TOKYO — Toyota Motor Corp said on Tuesday both the president and chairman of Daihatsu Motor will step down almost a year after the small-car unit said it had rigged collision safety-tests. The departures are among the most drastic changes Daihatsu has made so far, as Toyota seeks to return the brand to its roots as one of Japan's most iconic compact car makers. Toyota faces a potential hit to its reputation from the safety certification lapses at Daihatsu, as well as separate governance issues at truck maker Hino Motors and affiliate Toyota Industries. The scandals at the three companies triggered a rare apology of Toyota Chairman Akio Toyoda last month. In a statement, the world's top-selling automaker said its chief executive officer for the Latin America and Caribbean region, Masahiro Inoue, will replace Soichiro Okudaira as Daihatsu's president effective March 1. Daihatsu's chairman, Sunao Matsubayashi, will also step down and will not be replaced, Toyota added. The outgoing Okudaira had worked at Toyota for nearly four decades before becoming president of Daihatsu in 2017, a year after it became a wholly owned Toyota subsidiary. Toyota Chief Executive Koji Sato told reporters, however, that the organizational change at Daihatsu was not carried out as a punishment for the outgoing executives. In volume terms, Daihatsu accounted for 7% of Toyota's total group sales of 11.2 million vehicles in 2023, including those of the luxury Lexus brand and Hino Motors. Given the misconduct over the safety test certification applications, Daihatsu also will be removed from a commercial vehicle partnership known as the Commercial Japan Partnership Technologies (CJPT), the automaker said in a separate statement. The partnership was established in April 2021 by Toyota, Hino and Isuzu Motors to facilitate technology development for commercial vehicles. Suzuki Motor and Daihatsu joined in July the same year. Daihatsu's 10% equity stake in the partnership will be transferred to Toyota, the statement said.

Toyota engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.
