Dutch Toyota dealer has plans for old Prius batteries as solar backup

A Toyota dealer in the Netherlands is looking to the sky for power. The Louwman Hague Toyota dealership has put almost 1,000 solar panels on the roof, and there might be some Prius hybrid batteries involved. Our Dutch isn't as good as it could be and our questions to Toyota in the US haven't turned up any definitive answers, but there is some mention that these solar panels are will someday be feeding power into a bank of Toyota hybrid batteries. The 1,000 panels make up 1,600 square meters, about the size of 4.5 IMAX movie screens, and is the largest in the area. They generate around a quarter of a megawatt of energy [as our readers point out, this is what the translation says, but it doesn't make sense, so we think it might mean a quarter MW of power a day], which is enough to power 80 homes. The excess electricity will go into the battery packs that have (possibly) already been used in a Prius or another of the company's hybrid. There are many examples of automotive batteries being tested as stationary back-up power sources, and maybe this Dutch solution can be used as a guide when Toyota sets up its new US headquarters in sunny Texas.

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.

Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?
