Only Solution. A fueling station for the Mirai must adhere to the most recent Society of Automotive Engineers (SAE) hydrogen fueling interface protocol standards or regulations that may replace such SAE requirements. The Mirai is a hydrogen-powered fuel cell vehicle.

Does your Toyota Mirai have gas?
A new era of zero-emission mobility fueled by hydrogen has arrived with the Mirai.
The Japanese word for Mirai is “future,” yet in order for our innovative Toyota Fuel Cell System technology to be a success, it must be appealing to and available to people now. Despite having a cutting-edge drivetrain and utilizing a novel fuel, the Mirai is a typical mid-size, four-door sedan that is just as useful, secure, and simple to operate as a conventionally powered family car.
On a full tank of hydrogen, it will travel as far as a comparable-sized gasoline vehicle, and filling up from empty takes between three and five minutes. The benefits include a quiet, comfortable ride, high performance, and only water vapor emissions from the exhaust.
A interaction between hydrogen and oxygen generates energy in the Toyota Fuel Cell System seen in the Mirai.
In the same way that you purchase gasoline or diesel at a filling station, you refuel with hydrogen fuel. The fuel is kept in high-pressure tanks and pumped into a fuel cell stack, where the air’s hydrogen and oxygen interact to produce electricity.
Similar to a gasoline-electric hybrid, the voltage of the electricity is increased to power the electric motor. Every time the car brakes or slows down, more energy is stored in a battery, which results in even improved fuel efficiency.
We are the first company in the world to provide a system with a power density of 3.1 kW per liter thanks to our decades of research and development in hybrid electric technology.
What is the price of a Toyota Mirai’s fill-up?
Some automobiles are pricey to buy, while others are pricey to own. The average price of hydrogen fuel is $16 per kilogram, thus filling up a Toyota Mirai might be rather expensive. Since the Mirai typically holds 5 pounds, your cost would be about $80.
It should be mentioned, nevertheless, that hydrogen fuel is significantly more effective than gasoline. On the interstate, a Mirai can do 71 miles per kilo, and 76 in the city.
Can I refuel my automobile with hydrogen at home?
It should be simple for adults to create hydrogen to fill their fuel cell automobiles at home since kids can do it with nine-volt batteries for science fair projects. Wait a minute. It might make sense to extremely wealthy individuals who enjoy finding overly complicated solutions, but not to anyone else.
Can hydrogen be produced at home? Yes, electrolyzing water can produce hydrogen in a method that would be appropriate for a science fair. If you can collect all of the hydrogen in a liter of water, you will have around 111 grams of hydrogen. If you wanted to get hydrogen that was pure enough for your car, you would probably need one of these industrial electrolysis equipment. Your garage has lost one parking place as a result.
In a fuel cell vehicle, one kilogram of hydrogen is the same as one gallon of gasoline. Five kilograms can fit in the Mirai. To produce enough hydrogen to fill the tank, 45 liters, or nearly 12 gallons, of water must be electrolyzed. That makes perfect sense. The simple electrolysis would use about 167 KWH of power, costing roughly $20 USD at a rate of 12 cents per KWH (the US average).
However, the volume is an issue. The volume of the five kilos of hydrogen as a room temperature gas is 6,175 liters. That is around 212 cubic feet or 6 cubic meters. Your science fair project would require a sizable hydrogen storage tank to be added to it. Another parking space is now gone.
You would next need to load it into your vehicle. That necessitates both chilling it down and compressing it. That is a complete process unto itself, complete with equipment and automated controls.
To get the full range out of a Toyota Mirai tank, you need H70 compression, which is 700 bar or 70 MPa. You are looking at 700 atmospheres of pressure, which is far higher than typical home compressors (a bar is equal to air at sea level). They typically stop operating at 14 atmospheres.
Due to their extreme small size and extreme flammability, hydrogen molecules provide a modest pair of issues. The first requirement is that all of this equipment must be produced with exceedingly close tolerances. Because they work with that extraordinarily thick fluid we call air, home compressors do not need to apply. The second implies that you must incorporate negative pressure backups and exhausts to the outside into the system as well, otherwise there is a significant risk that your garage will contain a sizable volume of combustible gas.
To acquire the proper amount of hydrogen safely, a Toyota Mirai has to know precisely what pressure and temperature of hydrogen it is receiving. Computer interlocks are necessary since doing without would result in problems like blowing a gasket at 700 atmospheres of pressure and flooding your garage with dangerous hydrogen. You would have something that appears like this in the end. A third parking space in your garage is now vacant.
H70 hydrogen fueling stations have a minimum cost of $500,000 USD due to the pumping, cooling, and computing components of all of this. Additionally, they order the hydrogen rather than producing it.
Sure. If you have roughly a million dollars to spend on it, you could build a three-car garage specifically for the hydrogen processing facilities that is far enough away from the house and the neighbors to not disturb them with the sound of pumps that can generate 700 atmospheres of pressure. If you’re wealthy enough to think about it, you undoubtedly have the cash to buy a few acres. Perhaps you don’t even mind taking a short stroll through your property to reach your remote garage.
Or you could just buy a battery-powered vehicle and spend a few hundred dollars having a plug installed for it. Additionally, given the largest battery for an electric vehicle is 100 KWH, with roughly the same range as the Mirai (and far greater performance), filling it up would only cost approximately $12.
Is hydrogen fuel less expensive than regular fuel?
Although hydrogen fuel is four times more expensive than gasoline and about $16 per gallon, it is far more efficient than gasoline. The cost of a fillup is high even though hydrogen cars, which have electric engines, have cruising ranges that are more than 350 miles longer than any battery-electric and some gas-powered vehicles.
The financial blow has been considerably mitigated by incentives. The state offers a $4,500 clean-car refund, and manufacturers supply refueling cards with three years’ worth of credit put on them. The first year of leasing a hydrogen vehicle, which is what most drivers do instead of buying, is mostly covered by that refund. New hydrogen vehicles cost around $60,000 and don’t come in as many model variants as battery-powered electric vehicles.
Aaron Slavin and his wife, who reside in the Altadena, California, neighborhood of Los Angeles, created a spreadsheet to analyze the benefits and drawbacks of driving a hydrogen-fueled vehicle. They came to the conclusion that keeping a gas-electric hybrid “didn’t pencil out.”
Aaron Slavin refueled his 2017 Toyota Mirai at a one-bay hydrogen pump concealed at a typical gas station in South Pasadena and declared, “I’m a big fan of this car; I preach about them.
Slavin, a producer of performing arts, claimed that because of his employment, lack of frequent commuting, and backup hybrid SUV, he is an ideal fit for the vehicle.
Last year, a fuel manufacturing facility explosion restricted supply for months, leaving some hydrogen stations with empty tanks, leaving some drivers stranded or demanding lengthy treks to alternate stations, making the second car essential. Slavin turned to a smartphone app that offered a real-time inventory of fuel at each station in response to the issue, which some drivers dubbed the “hydropocalypse.”
Although the gasoline issue has been fixed, it prompted a concern. Our lease expires in April, so I really need to consider our options, Slavin added. ” The automobile is nice, however the fuel situation worries me.
Hydrogen energy production has long been an alluring objective. After all, hydrogen is the most common element in the universe, it is lightweight and energy-dense, and when used in transportation, it doesn’t release greenhouse gases but rather little pools of water instead.
But this clean-burning fuel has a carbon history. About 95% of hydrogen fuel is created via an energy-intensive method that relies on methane, the deadliest of the planet-warming gases, even though once it is formed it drives zero-emission electric motors. Because of this, it is challenging for certain environmental organizations to promote hydrogen vehicles.
Director of the Sierra Club in California Kathryn Phillips said, “We need to remove methane out of the system, not create a dependency on creating more. ” The current utilization of state subsidies for hydrogen fuel cells is not the ideal one when seen from an environmental perspective.
Two responses are given by supporters: Why not trap and use the methane that is currently being released unregulated into the environment from landfills and oil and gas plants while the state makes the transition to a zero-carbon economy? Why not switch to a technique that doesn’t use methane and uses the state’s excess solar energy instead, making the manufacturing clean and environmentally friendly?
Hydrogen vehicles can’t compete in a key area: price, while having benefits over battery electrics or gasoline automobiles in terms of quicker filling, less weight, and greater range. The cost of a typical municipal bus could be $450,000. Similar standards for a hydrogen bus cost more like $1 million.
Lewis Fulton, a specialist in transportation at UC Davis, claims that hydrogen “presents numerous separate chicken-and-egg challenges simultaneously.
He asserted that there won’t be more hydrogen fuelling stations until there are more vehicles built and bought. Furthermore, unless there are sufficient gas stations, customers might be concerned about getting stranded and may not feel safe operating the vehicles.
The only solution, according to Fulton, is a really strong policy push. “In the state, there is already one going on, but I’m not sure if it’s big enough.
As part of its ongoing conflict with the Trump administration, which last year took away the state’s jurisdiction to establish its own tailpipe pollution rules, California’s efforts to promote the market for hydrogen cars could be hindered. Car manufacturers who supported looser emissions regulations with the federal government will pay a price by having their vehicles removed from the state’s fleet.
Toyota, which sided with Washington, would be excluded at a time when the business is stepping up its hydrogen program and is anticipated to dramatically increase customer awareness of hydrogen vehicles due to its position as a major multinational automaker.
Supporters played minimized the problem. Eckerle acknowledged that there was an issue. He continued, however, that there has been no sign from automakers that they plan to back out of their commitment to producing hydrogen-powered vehicles.
Why is fuel made of hydrogen so expensive?
The majority of hydrogen utilized in the United States is generated on-site or nearby, often at sizable industrial facilities. It is still necessary to build the infrastructure for supplying hydrogen to the vast national network of fuelling stations needed for the widespread deployment of fuel cell electric vehicles. Building out these distribution networks is the primary objective of the initial rollout for vehicles and stations, which is predominantly done in southern and northern California.
Currently, there are three ways to deliver hydrogen:
Pipeline: This method is the least expensive for delivering large amounts of hydrogen, but it has a limited capacity due to the fact that there are only 1,600 miles of hydrogen transport pipes in the United States at the moment. These pipelines are situated close to significant chemical and petroleum refineries in Illinois, California, and the Gulf Coast.
High-Pressure Tube Trailers: High-Pressure Tube Trailers are expensive and are often used for transporting compressed hydrogen gas over lengths of 200 miles or fewer by truck, railway, ship, or barge.
Cryogenic liquefaction is a technique that cools hydrogen to a temperature where it turns into a liquid, producing liquefied hydrogen tankers. Despite the cost of the liquefaction process, hydrogen may be delivered by truck, railcar, ship, or barge over larger distances more effectively than using high-pressure tube trailers. If the rate of consumption of the liquefied hydrogen is insufficient, it will boil out (or evaporate) from its containment vessels. The distribution and consumption rates of hydrogen must be precisely coordinated as a result.
There are numerous difficulties in developing an infrastructure for hydrogen transport and distribution to thousands of individual fuelling stations in the future. Hydrogen is more expensive to transport, store, and deliver to the place of use than all other fuels because it has a lower energy density per unit volume than all other fuels. The initial capital expenses of constructing a new hydrogen pipeline network are considerable, and the properties of hydrogen create special difficulties in the design of compressors and pipeline materials. However, as hydrogen can be created from a wide range of resources, regional or even local hydrogen production can make the best use of available resources while reducing distribution issues.
Between centralized and dispersed manufacturing, there are trade-offs to take into account. Centralized generation of hydrogen in sizable plants lowers production costs but raises delivery expenses. For instance, producing hydrogen at filling stations reduces distribution costs but raises production costs due to the expense of setting up on-site production facilities.
Research and development initiatives by the government and business are removing the obstacles to effective hydrogen delivery. The Office of Hydrogen and Fuel Cell Technologies has more information about hydrogen delivery.
Why is the Mirai priced so low?
The Toyota Mirai is one of only two hydrogen-powered automobiles that are currently being produced, making it relatively special. Although hydrogen technology is by no means new, it has only ever been utilized in concept cars, which makes Mirai a unique automobile.
We must examine every facet of operating and maintaining a hydrogen fuel cell vehicle in order to comprehend why the Mirai is so inexpensive (FCV). Even if you have no plans to purchase a Mirai, I urge you to read this article because the concept behind it is both fascinating and ground-breaking.
The simple answer is that the Mirai is affordable due to the significant incentives provided when purchasing a new model, the most popular three-year lease with free fuel, a dearth of charging stations, and some consumer skepticism over the technology.
