He said the best hydrogen fuel cell technology doesn't compare to the energy density of lithium-ion batteries

Tesla Motors CEO Elon Musk has made his view on hydrogen fuel cell cars clear: they're bullshit.

In a a speech at a new Tesla service center in Germany, Musk told employees and enthusiasts that those who oppose electric vehicles (EV) but are onboard with new technology like hydrogen fuel cell cars need to know that it's more of a marketing gimmick than a real clean energy solution. 

 “And then they’ll say certain technologies like fuel cell … oh god … fuel cell is so bullshit. Except in a rocket," said Musk.

More specifically, Musk said that even the best hydrogen fuel cell technology doesn't compare to the energy density of lithium-ion batteries, such as that found in Tesla's Model S. 

Check out the video below for Musk's comments, which start at the 29-minute mark:

Musk may hold this opinion because his company only offers EVs for the time being, but not all automakers feel that hydrogen fuel cell is a waste of time.

Earlier this month, Toyota said it was passing up EVs in favor of more hybrids and its first hydrogen fuel cell release in 2015. According to Toyota Chairman Takeshi Uchiyamada, EV batteries need at least two major breakthroughs before they can replace gasoline or hybrid vehicles. 
"The reason why Toyota doesn’t introduce any major [all-electric product] is because we do not believe there is a market to accept it,” said Uchiyamada. "I personally expect a lot from this hydrogen fuel cell technology. If government and industry work together, this might be part of the long-term solution."

Back in July, General Motors (GM) and Honda announced that they'd team up for fuel cell vehicle technology as well. They hope to commercialize the technology by 2020. 

However, GM still has a foot in the EV market as well. In fact, it wants to directly compete with Tesla by offering a 200-mile affordable EV. Tesla said it is working on a new vehicle with the same range, which aims to be more affordable than the current Model S. GM is also gunning for Tesla with luxury Cadillac EVs

Others onboard with Musk's love for EVs is Volkswagen, which wants to lead the EV market by 2018 starting with the eGolf and eUp!, and Nissan, which has upped its EV efforts by cutting purchase and lease prices of the all-electric Leaf and even offering free charging for a year to Leaf owners in Texas (and eventually other states).

Tesla is certainly a superpower in the EV startup realm. The company successfully paid off its $465 million government loans nine years early, pulled a surprise profit for Q2 2013 with a revenue of $405.1 million, unveiled new tech for its Model S (swappable battery tech) and the Model S even snagged the highest safety rating from the NHTSA. It makes sense that Musk would try to keep this momentum going by advocating EVs over hydrogen fuel cells.

The problem with hydrogen is that it has to be stored under pressure, while the other fuels you cited do not.

There is a big difference.

the other fuels you cited do not
(have to be stored under pressure)

like propane, ethane, methane, hexane, acetylene .

The Vantage pipepline (ethane) engineers disagree with you. They transport at 1440 PSI. I am quite sure that the storage is typically done at significantly higher pressures. Likewise, I haven't seen any non-pressurized propane, or natural gas (methane) vehicles.

Don't believe me, check out

Actually, according to sources, propane turns into liquid at just 127 psi.

Hydrogen, on the other hand, requires 3000 psi or above to keep it from vaporizing, compared to 1440 psi in the Vantage pipeline.

It is one thing for a group of professionals to lug that stuff around, and quite another to have the general public careening down the road at 80mph while stoned and texting on their cell phones.

Pressure or not, still a generally bad idea. Batteries tend to catch fire to be sure, and that is a bad thing, but we have not seen many explode in any hollywood sense of the term.
