New Toyota Mirai videos continue questionable hydrogen claims

"Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint." Toyota has released a number of new promotional videos for the hydrogen-powered 2016 Mirai. Most are exactly what you'd expect: pretty, full of promise and vaguely informational. But there was one line in the Product Introduction video that caught out ear. In the Product Information video about the Mirai, the narrator goes into a short history of Toyota's green car advances. After talking about the Prius and the Prius Plug In, making EVs for urban commuting and the rest of Toyota's advanced fuel programs, we hear this: "Never satisfied though, Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint, one that took its lead from nature itself." You can watch the video (and four others) below. Plug In America co-founder Paul Scott told AutoblogGreen, "Show us the math! Toyota claims the FCV has a smaller carbon footprint than their EV, but every paper I've read indicates the FCV uses 3-4 times as much energy to travel a given distance as an EV. If they are making this claim, let's call them out to prove it. Show us the math!" There's some math that comes out in favor of EVs here and here. "BEVs and FCs have a very similar carbon footprint, dependent on fuel source." – Toyota's Jana Hartline Plug-in vehicle advocate Chelsea Sexton went further. "Assuming appropriate comparisons in energy feedstock, basic science doesn't support the notion that the footprint of an FCV is smaller than that of an EV," she told AutoblogGreen, explaining that "appropriate comparison" would mean using similar energy generation methods for both hydrogen and plug-in vehicles. Not the tendency, she noted, "of H2 fans to compare FCVs based on solar-based electrolysis to EVs running on coal-bases electricity and similar shenanigans." Besides, Sexton said, "focusing purely on efficiencies entirely misses the biggest struggles that FCVs face in the market, namely fuel price, inconvenience, and market fear, even if the vehicles themselves are initially subsidized.

Honda Accord barely edges Toyota Prius as California's best-selling car

The Toyota Prius definitely still matters, at least to car buyers in California. The long-lived hybrid was the state's second-bestselling vehicle in 2014 by moving 71,210 units across all of its variants, including the Prius C. The Toyota was the leader there in 2012 and 2013 but lost the sales crown this time – just barely – to the Honda Accord, which sold 71,578 examples. The results in the Golden State illustrate just how different the auto market there is compared to the rest of the country. Prius sales slumped last year nationwide with a drop of 11.5 percent to 207,372 examples sold. However, according to the LA Times, the model's numbers ticked up two percent in California in 2014. Taken by itself, the standard hatchback model would have been the sixth-bestseller there, with 39,036 units purchased. While the Toyota showed modest growth, it wasn't enough to fend off the Accord's 17 percent year-over-year jump in the state, though. According to the Los Angeles Times, the rest of the California top ten included the Honda Civic, Toyota Camry, Corolla, Ford F-Series, CR-V, Nissan Altima, Sentra and Chevrolet Silverado, respectively. That list was quite a departure from the nationwide bestsellers in 2014, which was led by the F-Series, Silverado and Ram pickups. The Camry was the country's foremost car on the list in fourth place overall to beat the Accord in fifth. The Prius didn't break into the ten biggest sellers in the US last year.

The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.
