How much hydrogen does it take to run a fuel cell?
Most fuel cell electric cars carry about 5 kg to 6 kg of hydrogen but go twice the distance of a modern internal combustion engine car with equivalent gas in the tank, which works out to a gasoline-per-gallon equivalent between $5 and $6.
How much energy does hydrogen release?
A small part (2% in 2019) is produced by electrolysis using electricity and water, consuming approximately 50 to 55 kilowatt-hours of electricity per kilogram of hydrogen produced.
Can you use a fuel cell to separate water into hydrogen and oxygen?
Electrolysis is the process of using electricity to split water into hydrogen and oxygen.
How much energy does it take to make a kilogram of hydrogen?
How much electricity is needed to make hydrogen? A completely efficient electrolysis system would require 39 kWh of electricity to produce 1 kg of hydrogen. However, the devices commonly found in operation for this process are less efficient. A typical operational figure is about 48 kWh per kg of hydrogen.
Is hydrogen cheaper than electric?
Yet, another situation is the efficiency of the process, that’s only 75% efficient and allows for 25% of electricity loses. This is why most today most hydrogen fuel is obtained is by the process of natural gas reforming, which is less expensive than electrolysis.
How far can you drive on hydrogen?
A full hydrogen tank will last around 300 miles (approx. 480 kilometers). Battery-powered cars can match this with very large batteries – which in turn will lead to an increase in both vehicle weight and charging times.
Can hydrogen cars be fast?
The car, called the H2 speed, could reach up to 299 km/h (186 miles per hour), casting a great big shadow on the specs offered by the Toyota Mirai. This also makes it the first high-performance hydrogen-car capable of going from zero to 100 km/h (62 miles per hour) in just 3.4 seconds.
