What we need to know about hydrogen fuel-cell cars

When it comes to offered a immature vision, hydrogen appetite has an advantage: a potion of pristine H2O a usually thing spilling from your tailpipe. Despite that, fuel-cell formed cars have been delayed to strech a market, yet your options in a US are set to double – to, admittedly, dual models – by a finish of a year.

The wheels aren’t cheap

Hydrogen powered vehicles aren’t new to open roads, yet it’s usually in a past year or so that they’ve shifted from a things of fleets and sailing investigate drivers to something a open in ubiquitous can drive.

2016 Toyota Mirai fuel-cell car

Toyota began deliveries of a Mirai sedan in a US late final year, while Hyundai’s Tucson Fuel Cell isn’t now accessible in a US. Honda, meanwhile, pronounced this week that a Clarity Fuel Cell should go on sale before 2016 is out, with an approaching cost of around $60,000.

That series is familiar, given Toyota launched a Mirai during $57,500. The franchise prices – important, given conjunction Toyota nor Honda will sell we a fuel-cell automobile undisguised yet, usually franchise one to we for 3 years – are effectively matching too, during around $500 a month.

It’s a lot, generally when we cruise how many of a cars are technologically matching to their electric hybrid siblings in any company’s range. The Mirai, for instance, borrows copiousness from a Prius, including a nickel-metal hydride batteries and electric motors; a usually disproportion is that it gets a appetite from a fuel-cell complement rather than a gas engine.

Scarcity won’t usually be a cause of price, however. Toyota has launched a Mirai both in tiny numbers and in a tiny apportionment of California; Honda aims to do a same. It’s partly a thoughtfulness on a cost of a record itself, yet partial since nobody utterly knows what a marketplace for a fuel-cell automobile will be.


There’s also a plea of handling expectations. Whereas many automakers are inspired for automobile sales, opting for hydrogen involves tighten to an audition: we need to be in a right area, with a right approaching use pattern, and entirely sense a positives (and probable shortcomings) hydrogen entails.

Honda isn’t holding preorders for a Clarity Fuel Cell yet, yet it’s expected to follow a identical routine to that of Mirai: after all, it’ll usually take a few disastrous reports from early-adopters to impact a brakes on a hydrogen train.

Low on gas

Actually anticipating a automobile is usually a initial headache: once you’re behind a wheel, reckoning out somewhere to refuel becomes your subsequent struggle. Unlike normal gasoline, a infrastructure for that has had decades to develop, and electricity, that can – in speculation during slightest – ping y-back on existent high-voltage wiring, there are no hydrogen piping options already out in a wild.


The outcome is a small, gradually flourishing network of places where we can find hydrogen, and a satisfactory grade of formulation required.

There’s an evidence to be finished that many of a range-anxiety is in drivers’ heads rather than reality. Research by a University of California Irvine’s Advanced Power and Energy Program, for instance, found that – formed on a arrogance that fuel-cell automobile drivers would wish to strech a hire within 6 mins or less, and given standard trade and race firmness – just 68 sites would be needed opposite San Francisco and Silicon Valley, LA, Orange, and San Diego county.

Such a series could support around 10,000 hydrogen-powered vehicles, distant some-more than is expected to be concerned even when Honda joins a celebration after this year, a researchers said.


Combating a notice of wily recharging competence be a box of throwing some-more record during a situation, then. Toyota’s Mirai, for instance, has a tradition navigation complement with all a accessible hydrogen stations saved: from a dashboard or a car’s messenger app we can cause in refueling into your arriving trip.

But where does a hydrogen come from?

Gasoline comes in tankers and on trucks. Electricity comes by high-voltage cables. Where does hydrogen come from? Initially, during least, it’s another box of high-pressure tanks on a behind of trucks, yet there are skeleton stirring to furnish a fuel on-site instead.

“The infrastructure problem is a vital one,” Audi’s Siegfried Pint, conduct of electric expostulate development, told me during a North American International Auto Show in Detroit progressing this month. There, a association showed off a Audi h-tron quattro, a judgment of what a hydrogen-powered SUV competence demeanour like, yet came brief of committing to indeed creation it.

Instead, Pint said, fuel-cell record is being grown as a just-in-case preparation. Audi sees no tiny grade of interest with hydrogen – a “main advantage,” Pint forked out, is a low refueling time compared to electric cars, not to discuss a operation – yet is calm to wait and see either a open comes to direct that before it weighs in on a market.

In a meantime, though, it’s also been building hydrogen stations that can indeed furnish a fuel on-site, extracting it from healthy resources regulating whatever appetite supply is locally available. That could be solar or breeze power, perhaps, or rubbish appetite from a circuitously industrial facility.


Audi has no idea of apropos a hydrogen distributor itself, a company’s Dr Reinhard Hofmann insisted to me recently, yet sees investigate into such one-box hydrogen generators as an apparent together plan for a fuel-cell research. And, even if Audi itself won’t commercialize them, that doesn’t meant a growth is a dead-end.

“We would adore to share a IP,” electric expostulate arch Pint told me in Detroit. yet declined to contend either any such discussions had taken place already.

The immature question

Without environmentally-conscious ways to furnish hydrogen, only how ecologically fit fuel-cell formed cars indeed are is questionable. Just like an electric car, if a appetite source you’re relying on to fuel your travel is reliant on unwashed hoary fuels, all you’ve finished is change a CO2 outlay and other emissions to another location.

Hydrogen has some fundamental advantages over electricity in that respect. It presents new options for appetite travel – enormous H2O into hydrogen in one location, relocating it to another, and afterwards regulating it to appetite fuel-cells is arguably some-more unsentimental than using a prolonged cable, generally if your prolongation takes place offshore – and storing it involves a large tank rather than quarrel on quarrel of batteries.

That’s a theory, anyway. In practice, with a small fourteen open hydrogen stations in a US – a infancy in California – a aim of 100 by 2024 looks a prolonged approach off. Even with a roughly 300 miles of operation per tank that Toyota and Honda are promising, it’s a nonesuch that isn’t going to be helped by perplexing to cause difficult immature mandate in there, too.

Early-adopters, early-doubts

Hydrogen-powered vehicles positively have a intensity to be even greener and some-more unsentimental than their full-EV cousins, yet there’s a prolonged trek between a stream state of a fuel-cell diversion and that being loyal in practice. Neither Toyota nor Honda are putting open sales idea targets on their cars; in short, nobody is peaceful to conclude what qualifies as “success” and what looks like “failure”.
