Ever since Elon Musk “persuaded” Donald Trump to take it easy on his electric vehicle-bashing, the former president’s EV riffs have gotten pretty boring. Thank goodness, then, that there’s a new boogeyman in town: hydrogen cars.
Never mind that there are only about 18,000 hydrogen cars on the roads in the U.S. and so few refueling stations that one of the two manufacturers of them, Toyota, is getting sued. According to Trump, hydrogen cars are “the new thing,” as he warned his supporters last week during a stop in Savannah, Georgia (roughly 1,900 miles from the nearest hydrogen refueling station):
“They say the new thing is hydrogen cars, but they’re having a problem. If it explodes, you end up about seven blocks away. And you’re dead. So personally, I don’t know about you, but I’m gonna take a pass. But maybe they’ll figure it out. But right now, I wouldn’t recommend it.” [via RawStory]
This is, admittedly, a pretty funny bit — even if it’s totally inaccurate, according to Bill Elrick, the executive director of the Hydrogen Fuel Cell Partnership, a nonprofit group of auto manufacturers, energy providers, and government agencies that promote hydrogen vehicles in California. “I get where it comes from, and it is one of our biggest challenges in the industry — helping people understand what hydrogen is without diving into the depths of how a vehicle operates,” he told me.
As Elrick pointed out, when most people hear “hydrogen,” they think either of water (“which is fine”), the Hindenburg disaster (“we don’t do anything 100 years later the same way that we used to”), or, most problematically, the hydrogen bomb. “That’s something that is a completely different chemical reaction and, I think, where some of the safety scare comes from,” Elrick told me.
But hydrogen fuel cell vehicles (or HFCVs) are no more a bomb than gas-powered vehicles — perhaps less so, because they must meet the same rigorous safety codes and standards as any other car or truck on the road in addition to extra precautions to ensure the fuel cells won’t be punctured in a bad accident or potentially leak.
In a HFCV, hydrogen stored in a high-pressure tank is mixed in a fuel cell with oxygen from the air to induce a chemical reaction that produces electricity, which powers an electric motor that drives the car, just as it would in an EV. While batteries and electricity are familiar concepts, however, and therefore less scary as automotive power sources, current popular uses of hydrogen, such as refining oil and producing fertilizers, are not as visible to most people going about their daily lives as, say, their cell phones.
That’s not to say hydrogen is 100% safe. “Anything that moves a vehicle that weighs two tons or more — if it’s electricity, gasoline, or hydrogen — clearly has dangers and risks associated with it,” Elrick said. “If we could power our cars with peanut butter, it would have that energy potential.” But car manufacturers (just like electric boat manufacturers) have considered the possibility of their vehicles being involved in crashes and designed them accordingly.
The Center for Hydrogen Safety maintains a database of hydrogen-related accidents to serve as “lessons learned” as the technology continues to develop. Though there are still relatively few HFCVs on the roads, as of this spring there had been no recorded automotive fatalities credited specifically to hydrogen fuel cells. (In other words, no one has ended up “about seven blocks away” dead from an explosion.) One researcher even found that “in a collision in open spaces,” an HFCV should actually have “less potential hazard” than a gas car due to the extensive precautions taken when building their tanks (“their hardware would likely survive even if the rest of the car were destroyed in a crash,” per Car and Driver).
But Trump’s HFCV-phobia probably isn’t the biggest takeaway here. Some sectors of the hydrogen industry are potentially on the chopping block if Trump returns to the White House — since, as my colleague Katie Brigham writes, “green hydrogen made from renewable-powered electrolyzers is expensive and the proposed strict rules that would allow it to qualify for the most generous tax credit [would likely be] goners” under a Republican administration. Trump’s suspicion of new uses for hydrogen certainly doesn’t bode well.
As for any lingering fears about exploding hydrogen cars that Trump might have planted — hey, at least it’d be a quicker end than death-by-shark.
