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.

Final decision on Toyota/BMW sports car due by year end

BMW and Toyota signed a memorandum of understanding to share technology and build a sports car way back in 2012, and months later, they made that partnership official. This oft-rumored model from two auto industry titans still hasn't hit the road, and the time has come to make a final decision about its future. Thankfully, the model's fate is just a few months from being known. "By the end of the year we will approve whether or not we will make it," a Toyota spokesperson said about the sports car project, according to Automotive News Europe. "The whole study before that, on what kind of platform, on what kind of architecture, that's been progressing quite well. We haven't yet decided to give the green light to the project, but it's coming up." The collaboration is supposed to result in jointly developed fuel-cell tech, composites, and research into lithium-air batteries. Little is officially known about what Toyota and BMW are planning for the sports car project, but there are plenty of rumors about what's in store. Both automakers are supposed to get their own version of the vehicle. Some reports say the Japanese model will be the revival of the Supra, and the Bimmer-badged one might end up being a replacement for the Z4. The potential powertrains have been suggested as a German-sourced, turbocharged inline six with rear-wheel drive and a super-capacitor-powered plug-in hybrid with all-wheel drive.

Bibendum 2014: Former EU President says Toyota could lose 100,000 euros per hydrogen FCV sedan

Pat Cox does not work for Toyota and we don't think he has any secret inside information. Still, he's the former President of the European Parliament and the current high level coordinator for TransEuropean Network, so when he says Toyota is likely going to lose between 50,000 and 100,000 euros ($66,000 and $133,000) on each of the hydrogen-powered FCV sedans it will sell next year, it's worth noting. That was just one highlight of Cox's presentation at the 2014 Michelin Challenge Bibendum in Chengdu, China today, which addressed the main problem of using more H2 in transportation: cost. The EU has a tremendous incentive to find an alternative to fossil fuels, since Europe today is 94 percent dependent on oil for its transportation sector and 84 percent of that 94 percent dependency is imported oil. The tab for that costs the EU a billion euros a day, Cox said, on top of the environmental costs. To encourage a shift away from petroleum, European Directive 2014/94 requires each member state to develop national policy frameworks for the market development of alternative fuels and their infrastructure. For the member states that choose to fulfill 2014/94 by developing a hydrogen market – and to be clear, Cox said, it's not an EU diktat that they do so, since a number of other alternatives are also allowed – the aim is to have things in place by the end of 2025. The plans don't even have to be submitted until the end of 2016. The long lead time is due to a quirk in a hydrogen economy. In hydrogen infrastructure, "the first-mover cost is not the first-mover advantage, but the firstmover disadvantage." – Pat Cox In deploying a hydrogen infrastructure, Cox said, "the first-mover cost is not the first-mover advantage, but the first-mover disadvantage, and high risk." That's why the EU and member states will financially support the early stages, but everyone agrees that "if this is to work, it will have to be ultimately and essentially a commercially viable and commercially driven infrastructure roll-out." Since 1986, European Union research programs have spent 550 million euros on hydrogen-related and fuel-cell-related research, including methods of hydrogen storage and distribution as well as improved fuel cells vehicles, Cox said. Expensive problems remain to be solved. At a conference in Berlin, Germany this past summer, Cox said, the unit cost of the refueling stations was identified as the main problem.
