This episode of DNews is brought to you by Toyota’s Hydrogen fuel cell vehicles, Leave
your mark. Toyota, let’s go places.
It's 2015, Hollywood prophecy says we should have flying cars, and though we don't have
those… how about hydrogen cars?
Fueling your car with hydrogen is weird. Hydrogen, number 1 on the periodic table. It's a powerful
combustible element, it blew up the Hindenburg after all! But it's also part of water, and
carbohydrates, and so many other things in nature. The thing is… hydrogen is a lot
of things, and IN a lot of things, because it's a super simple element; one proton, one
electron and it makes up SEVENTY-FIVE PERCENT of the universe. Yeah, three quarters of everything
is hydrogen. Hydrogen is used for food processing, petroleum refining and in a variety of industrial
applications. The U.S. already creates more than 9 million metric tons of hydrogen annually!
So I say again, fueling your car with hydrogen is weird, but not THAT weird.
You've probably heard of hydrogen fuel cells, they've been around for a while. They were
first invented in 1839. They use oxygen and hydrogen to power a car with no moving parts,
and only emit clean water vapor when burned. And according to many car companies, 2015
might be the year the rubber meets the road for hydrogen as a fuel. When you think of
creating hydrogen, you probably think of this[a] but 95 percent of America's hydrogen is produced
using natural gas steam reformation. Factories use high temperatures and pressures to break
the natural gas into hydrogen (YAY!) and carbon oxides (BOO!). You can also make it using
electrolysis -- essentially running electricity through water to split the hydrogen from the
oxygen! Two great things! But something has to GENERATE that electricity, and in the U.S.,
that's usually coal power. But if we used wind, or solar -- then we'd be onto something.
Once it's made, it has to be cooled and stored, which uses MORE fossil fuel energy; and then
you have to ship it to pumping stations using trucks and trains… you get it. The HYDROGEN
is great, but we suck at making it and moving it around.
For now we're stuck making hydrogen using fossil fuels, which might not be ideal, but
that could all change once hydrogen vehicles get on the roads! Why buy a hydrogen car if
there's nowhere to fill it up! The government and private companies are partnering to get
fuel stations out there… California has a goal in place to have more than 15 percent
of all cars in the state be zero-emissions vehicles by 2025 -- and to hit that goal they've
pledged 200 million dollars to build 100 more fueling stations before then. There are already
10, though I don't imagine they're very busy since there aren't too many cars on the road
yet, but that'll change soon too.
In tandem with this momentum, a bunch of auto companies have pledged to release hydrogen
fuel cell cars this year, and with 100 more stations coming too, filling them up should
be a cinch! According to research from the University of California Davis, those 100
stations should be able to make fuel cell vehicles cost-competitive with gasoline!
We'd like to take a second and give a shout out to Toyota for supporting DNews. They were
at CES this week and released their patents for new fuel-cell technology, and revealed
THEIR fuel cell car to the world, the Mirai. They’re hoping these royalty-free patents
will spurn a hydrogen-fuel-based future and spent the last decade reducing the cost of
fuel cell production 95 percent.
Have you ever seen a hydrogen fuel station? Would you want a
hydrogen car?
