Is Hydrogen Fuel Cell Efficient?

Can hydrogen fuel cell cars explode?

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.

So in most cases, hydrogen doesn’t present as great a fire or explosive danger..

Does Tesla use hydrogen fuel cells?

Battery electric vehicles, or BEVs, are the electric vehicles that most of us are familiar with today, like Teslas. … A hydrogen fuel cell electric vehicle, or FCEV, like Toyota’s Mirai, combines hydrogen with oxygen to produce electricity, which then powers the electric motor that drives the car.

Are fuel cells efficient?

Fuel cell vehicles, which use electric motors, are much more energy efficient. The fuel cell system can use 60% of the fuel’s energy—correspond- ing to more than a 50% reduction in fuel consumption compared to a conventional vehicle with a gasoline internal combustion engine.

Are hydrogen fuel cells more efficient than batteries?

Depending on the model, the battery-powered e-car thus achieves an efficiency of between 70 to 80 percent.” The hydrogen fuel cell requires 2-3 times more energy to drive the same distance, as the overall Well-to-Wheel efficiency is from 25-35%.

Which is better electric vehicles vs hydrogen fuel cell?

Hydrogen fuel cell vehicles tend to be more frugal than their battery electric counterparts. According to Autocar, the Hyundai Nexo comes with a real-world range of 414 miles and filling up takes just five minutes, whereas electric charging can be an hour-long affair at the best of times.

How long do hydrogen fuel cells last?

The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today. A fuel cell stack is about the size of a roll-aboard suitcase.

What are the disadvantages of hydrogen fuel cells?

List of Disadvantages of Hydrogen Fuel CellsIt is expensive. While widely available, hydrogen is expensive. … It is difficult to store. Hydrogen is very hard to move around. … It is not easy to replace exiting infrastructure. … It is highly flammable. … It is dependent on fossil fuels.

Why Hydrogen cars are a bad idea?

The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car’s motors.

What are the problems with hydrogen fuel cells?

The only real problem is the issue of safety. Hydrogen is highly flammable – more so than regular fuel – and is harder to contain than oil. This means that any car fitted with a hydrogen fuel cells is a lot more likely to blow up or set on fire if it is exposed to extreme heat, if it breaks down or if it overheats.

Why are hydrogen engines a bad idea?

They burn clean, and they sound cool, but ultimately they don’t make much sense. Since hydrogen fuel (H2) doesn’t have carbon in it (like gasoline or diesel fuel), there’s no carbon added to the byproducts of combustion in a hydrogen engine. …

Can a normal car engine run on hydrogen?

This solution is simple, hydrogen engines. There are two types of hydrogen engines. A hydrogen fuel cell engine and a hydrogen internal combustion engine. … Say you have a petrol vehicle and convert it to run on hydrogen, your vehicle will still be able to run on petrol.

Hydrogen cars are stuck in a chicken-and-egg situation of supply and demand. … In addition, there are nowhere near enough hydrogen filling stations. This leads to a low demand for hydrogen, which means that little money is being invested into the new technologies.
