Is hydrogen more efficient than electric?
The hydrogen produced has to be compressed, chilled and transported to the hydrogen station, a process that is around 90% efficient. Once inside the vehicle, the hydrogen needs converted into electricity, which is 60% efficient. Finally the electricity used in the motor to move the vehicle is is around 95% efficient.
Which is better hydrogen or electric cars?
Hydrogen fuel cell EVs — the advantages
Hydrogen fuel cells have a far greater energy storage density than lithium-ion batteries, offering a significant range advantage for electric vehicles while also being lighter and occupying less space.
Why does Elon Musk not like hydrogen?
But Musk’s beef with hydrogen is that while it has the highest energy mass of any fuel, its density is so low that the pressure needed to store it, combined with adding fuel cell technology to create electricity, adds way too much complexity.
Why are hydrogen engines a bad idea?
The biggest reason why hydrogen-combustion engines are no good? They create nitrogen oxide, which isn’t good for people or the environment. Even though carbon isn’t part of the hydrogen combustion process, NOx isn’t a compromise as automakers look to zero-emission vehicles.
Are hydrogen cars efficient?
Hydrogen fuel cell vehicles, which use electric motors, are much more energy efficient and use 40-60 percent of the fuel’s energy — corresponding to more than a 50% reduction in fuel consumption, compared to a conventional vehicle with a gasoline internal combustion engine.
Are hydrogen cars zero emission vehicles?
Most fuel cell vehicles are classified as zero-emissions vehicles that emit only water and heat. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas.
What is the disadvantages of electric cars?
The first disadvantage is price. Electric car batteries are not cheap, and the larger the battery, the more you will pay. Many EVs start above $30,000 before incentives, and even the most affordable models from brands like Tesla can easily exceed $50,000 or even $60,000.
