Japan Is Betting Big On The Future Of Hydrogen Cars

It may feel as though the electric car has been crowned the future of transportation.

Auto companies have plans to make more electric car models, and sales — still only a tiny fraction of the overall market — are expected to get a boost as more countries pass regulations to reduce carbon emissions. But Japan isn't sure that the battery-powered electric car is the only future, and it's betting big on something it says makes more sense in big cities: hydrogen fuel cell vehicles.

At the LFA Works factory in the city of Toyota, Aichi prefecture, workers install carbon-fiber hydrogen tanks on Toyota's new hydrogen powered fuel cell car. It's called the Mirai, which means "future" in Japanese.

A hydrogen fuel cell doesn't burn anything. It uses a chemical reaction between the hydrogen and the oxygen from the air to produce electricity. Hydrogen fuel cell cars are quiet, like battery electric ones, and they emit only water.

At this tiny factory, located inside Toyota's larger Motomachi plant, only about 10 cars are made each day, assembled by hand.

"I love Mirai," says plant manager Matsuo Yoshiyuki, who owns one of the vehicles. "I believe in the future of hydrogen. It's very important for the [environment]."

Only about 11,000 fuel cell vehicles are on the road worldwide. Nearly half of them are in California, which has stringent vehicle emission regulations and tax credits that incentivize electric and fuel cell vehicles.

In Japan, the Mirai is expensive even with a generous government subsidy that brings it down from the equivalent of about $70,000 to about $50,000. The largest cost is the fuel cell production, but Toyota says that will drop as production ramps up.

Japan has embraced the technology and aims to create the first "hydrogen society," which also includes the use of hydrogen for power generation. The energy ministry has ambitious targets in the lead-up to the 2020 Olympics. The city of Tokyo plans to deploy 100 hydrogen fuel cell buses during the games, and it wants to have 40,000 fuel cell electric vehicles on the road, with a longer-term goal of 200,000 such vehicles in the next six years.

More convenient than plug-in electric

Today there are far more battery electric vehicles on the road than hydrogen cars, with more than 5 million plug-in cars worldwide, according to José Pontes, an analyst at EV-Volume.com, a website that tracks the industry. But in countries like Japan, where much of the population lives in dense urban areas, many people live in apartment buildings without a place to easily charge a car. It's here where companies like Toyota are banking on the convenience of the hydrogen fuel cell.

"There's just no behavior change as long as you have [hydrogen] infrastructure in place," says Matthew Klippenstein, co-author of the online publication Fuel Cell Industry Review. "We go to the same gas station and fuel up in the same few minutes and just keep on tootling on."

In South Korea, where the majority of residents also live in urban areas, automaker Hyundai just announced that it plans to produce 700,000 fuel cell cars a year by 2030.

Klippenstein likens the divide between hydrogen fuel cells and battery electric plug-ins to the gasoline and diesel split familiar to American consumers. "We will see a similar split where batteries will, for decades at least, dominate the light duty vehicle passenger cars," he says, "whereas fuel cells will ultimately win out in the heavier applications."

Meanwhile, Japan is investing heavily to create the infrastructure needed to promote hydrogen vehicles. It is tough to sell a hydrogen car without a lot of places to fill it up. But without more cars on the road, such fueling stations are not a smart investment for private companies.

So the Japanese government has stepped in with subsidies. The country, along with private companies like Toyota, has helped build and operate 100 hydrogen fueling stations so far. Japan has a target of 900 by 2030. By then, Toyota hopes there will be enough hydrogen vehicles to make the stations profitable.

There aren't enough hydrogen fuel cell cars in Tokyo to make fueling stations like this one profitable, so the Japanese government subsidizes them.

Not necessarily carbon-free

Another advantage of hydrogen could be reducing Japan's heavy reliance on Middle East oil. Hydrogen is abundant, and the fuel could be produced anywhere. But producing hydrogen fuel is itself energy intensive, and — just as with battery electric vehicles — it might be produced using natural gas or coal.

"So it's not really clean if that is the case," says Kimiko Haraka of the Kiko Network, a Japanese environmental group.

Haraka is critical of a plan by a number of Japanese companies, including Kawasaki Heavy Industries, J-Power, Iwatani Corp. and Marubeni, to build a plant in Australia that would use lignite coal to produce hydrogen for fuel cell vehicles. She also worries that the many subsidies for hydrogen come at the expense of promoting renewable energy.

Still, Bertel Schmitt, a former car industry advertising executive who lives in Tokyo, says it makes sense for Japan and its automakers to include hydrogen vehicles in their long game plan.

"They pretty much realize that the exhaust regulations will get tougher and tougher," he says. "What is being enacted right now, in 2020 in Europe, is nothing compared to what will come five years later, 10 years later."

For now, though, Schmitt says the internal combustion engine remains the cheapest and most convenient car on the market. Despite massive investment, he says Toyota knows hydrogen won't be taking over the roads anytime soon.

"They know that the guy sitting in the hydrogen fueling station will be very, very lonely for quite a while."

Auto companies are making more electric vehicles, ones powered completely by batteries. And sales should get a boost as more countries pass regulations to reduce carbon emissions. Japan, though, is betting big on something else. Susan Phillips of member station WHYY reports.

SUSAN PHILLIPS, BYLINE: Mirai means future in Japanese. It's also the name of Toyota's hydrogen-powered fuel cell car.

HIROO SASO: This is the engine noise of this car, so quiet.



PHILLIPS: I'm driving with my translator, Hiroo Saso, west of Tokyo, hoping to spot Mount Fuji.

SASO: Then soon, turn right to the viewpoint.


SASO: Sorry, slow down. Slow down.

PHILLIPS: Slow it down?

When we pull over, the Mirai is a head-turner. One man wants to check under the hood. Unlike a combustion engine that burns gasoline, a hydrogen fuel cell doesn't burn anything. It uses a chemical reaction between the hydrogen and the oxygen from the air to produce electricity. The only emission out of its tailpipe is water. Tadashi Hirano is looking at the Mirai for the first time.

SASO: You want to buy this - tempted to buy?


PHILLIPS: Right now it's too expensive for him, even with a generous government subsidy that brings it down from the equivalent of $70,000 to $50,000. Toyota says the price will drop as production ramps up.


PHILLIPS: At the LFA Works factory in Toyota city, workers install the carbon fiber hydrogen tanks on a new Mirai. These are all made by hand, only about 10 each day. Taiyo Kawai helps develop fuel cell infrastructure for Toyota.

TAIYO KAWAI: (Speaking Japanese).

PHILLIPS: Kawai says right now, Japan relies heavily on Middle East oil. Producing hydrogen fuel is energy intensive, but hydrogen is abundant. And the fuel could be produced anywhere. Toyota and other carmakers like Honda and Hyundai are also banking on the fact that hydrogen fuel cell cars are more convenient. Yoshikazu Tanaka is Toyota's chief engineer.

YOSHIKAZU TANAKA: (Speaking Japanese).

PHILLIPS: Tanaka says filling up a car with hydrogen is easier and faster than charging a battery on an electric vehicle. It makes more sense for people who live in dense cities and don't have a convenient place to plug in. A tank of hydrogen gets you farther than a fully charged battery, which makes it more efficient for trucks and buses. Ken Koyama from the Institute of Energy Economics, a Japanese think tank, agrees that hydrogen is a good bet.

KEN KOYAMA: We are always talking about long-run future. It's not the next year or five-year time horizon. It's 20 years, 30 years, 40 years, 50 years - because if we are really thinking about climate change, it's a very, very long-term strategy.

PHILLIPS: But so far there are only about 11,000 fuel-cell vehicles on the road worldwide, nearly half in California. The biggest challenge is building the infrastructure needed to drive them.

Our first order of business now is to fill up the tank.

SASO: Yeah, fill up the tank.

PHILLIPS: Back in Tokyo, we find a station that has a big H2 sign.

Nobody's here, just us.

SASO: (Speaking Japanese).

KEN KAWAKATSU: Maybe maximum - (speaking Japanese) - maximum, 15 cars a day.

PHILLIPS: The station attendant, Ken Kawakatsu, says he doesn't get many customers - 15 a day at most. So right now, these stations are operating at a loss. But they're subsidized by the Japanese government. If all its investments pay off, the country hopes to have 200,000 hydrogen cars, trucks and buses on the roads here in Japan in the next six years.
