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.

Lexus NX will be produced in Canada

OTTAWA/MONTREAL — Toyota Motor Corp will build its Lexus NX luxury crossover vehicle at a Canadian plant starting in 2022, the company said on Monday, a decision that Prime Minister Justin Trudeau said demonstrated the value of the country's international trade agreements. The plant will invest hundreds of millions of dollars to produce the Lexus NX and its hybrid version at the factory in Cambridge, Ontario, "supplying the entire North American market," Trudeau said in a presentation with Fred Volf, president of Toyota's Canadian unit. Citing Canada's trade agreements with Mexico, the United States, Europe and Asia, Trudeau said: "We have preferential trade access to two-thirds of the global economy. In fact, we're the only G7 country that has free trade deals with every other G7 country." Trudeau, who faces a tough re-election contest in October, said the plans by Toyota, one of the world's largest carmakers, will help guarantee 8,000 jobs and the factory. The announcement is a "counter narrative" for Canada's automaking industry following recent bad news from other automakers, said Flavio Volpe, president of the Toronto-based Automotive Parts Manufacturers' Association, especially in the province of Ontario. Fiat Chrysler Automobiles NV said in March it would cut a shift at its Windsor assembly plant, leading to 1,500 job losses, and General Motors said last year it would shut its Oshawa factory by the end of 2019. Plans to assemble the NX in Canada "means that Toyota's Canadian manufacturing operations are here to stay," Volf said, adding that the cars are "the most technologically advanced and the most in-demand cars in the Toyota-Lexus global lineup." On Sunday, Trudeau hosted Japanese Prime Minister Shinzo Abe in Ottawa. Both touted the benefits of a Pacific trade deal that U.S. President Donald Trump walked away from. Trudeau said he had discussed the project to build the Lexus NX in Canada with Chief Executive Akio Toyoda on April 1. "When we last chatted just a few weeks ago, we discussed the potential of this new Lexus mandate," Trudeau said.

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).
