Is hydrogen a viable fuel source?
Is hydrogen a viable fuel source?
Hydrogen is also a potent source of clean energy. In fact, it has the highest energy content of any fuel we use today [source: U.S. Energy Information Administration]. Hydrogen itself isn’t available on Earth, but it can be produced.
Is hydrogen a safe fuel for cars?
The short answer is that hydrogen behaves differently from gasoline. But generally it is about as safe as the gasoline we now put in most vehicles’ fuel tanks. Its vapors don’t pool on the ground, as do gasoline’s heavier-than-air vapors. So in most cases, hydrogen doesn’t present as great a fire or explosive danger.
Why are there not more hydrogen fueled cars?
Here are some of the reasons why there aren’t more hydrogen-fueled cars on the road. A fuel cell is built with an electrolyte membrane, an anode, and a cathode. Hydrogen passes through the fuel cell anode while atmospheric oxygen passes through the cathode. A catalyst splits the hydrogen molecules into protons and electrons at the anode site.
How is hydrogen used as a fuel source?
The use of hydrogen is a net energy loss at every stage, from production and storage, to transportation, distribution and eventual use in electric vehicles. It is much more efficient to generate electricity with wind or PV power, and store it in batteries (which are an existing and rapidly improving technology) for use in electric vehicles.
Are there any hydrogen fuel cell electric vehicles?
There is, however, a niche market for hydrogen IC vehicles operating where there could otherwise be an accumulation of CO-rich fumes, such as fork-lift trucks in warehouses. Earlier articles in this series present a case study, “ Enabling Hydrogen Fuel Cell Electric Vehicles ”, and look at the Toyota Mirai.
Which is better hydrogen fuel cell or IC engine?
Fuel cells represent a better utilisation of hydrogen energy in cars than a hydrogen-fuelled IC engine, which is only about 40% compared to the possible 56% shown in Table 1 2 (blue rows show hydrogen fuel cell, and grey and green show petrol and biodeisel IC).

Which is safer, a hydrogen fuel cell or an internal combustion engine?
Hydrogen is explosive, but supply is a bigger issue for the nascent industry. Honda. For all the volatility of a gas like hydrogen, which combusts with one-tenth the energy required for gasoline, hydrogen fuel cell vehicles are safer than cars with internal combustion engines, according to industry experts.
Which is more expensive hydrogen or electric cars?
Hydrogen, however, has no such favorable arithmetic yet. Fuel cell cars themselves are more expensive to purchase new, and the hydrogen fuel costs work out to roughly $5.60 a gallon today according to the California Fuel Cell Partnership.
