$0.0015/gallon + $0.987/kg (gge) Refining Costs = $0.9885 = $1.00/kg (gge) using Atmospheric Electrolyses. ÷ 50 gallons per drum = 6.66 “barrels of H2” per 1000 gallons of water. That is equivalent to a 7:1 H2 to crude oil ratio. Energy needed to make 1 kg of H2 = 32.9 kWh/kg.

Why hydrogen cars are a bad idea?
Hydrogen fuel cells have bad theoretical and practical efficiency. Hydrogen storage is inefficient, energetically, volumetrically and with respect to weight. … It has a horrible well-to-wheel efficiency as a result. Easy ways to get large quantities of hydrogen are not ‘cleaner’ than gasoline.
How does a hydrogen engine work in a car?
Like an internal-combustion engine, they make power by using fuel from a tank (though the fuel is pressurized hydrogen gas rather than gasoline or diesel). … In the process, which resembles what happens in a battery, electricity is released and this is used to power an electric motor (or motors) that can drive a vehicle.13 avr. 2021
What is the problem with hydrogen cars?
The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
How many MPG does a hydrogen car get?
Typically, a fuel-cell system is twice as efficient as a gasoline system. Most of the fuel-cell vehicles coming to market in the next few years will be able to deliver close to 70 miles per kilogram of fuel. That’s the equivalent of 70 miles per gallon.22 mai 2014
Why are hydrogen cars better than electric?
However, as hydrogen cars densely pack their energy storage, they’re usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.
What are the disadvantages of hydrogen?
1. It is expensive. While widely available, hydrogen is expensive.
2. It is difficult to store. Hydrogen is very hard to move around.
3. It is not easy to replace the existing infrastructure.
4. It is highly flammable.
5. Fossil fuels are often used to produce it.
Can a normal car engine run on hydrogen?
Hydrogen has a wide flammability range in comparison with all other fuels. As a result, hydrogen can be combusted in an internal combustion engine over a wide range of fuel-air mix- tures. A significant advantage of this is that hydrogen can run on a lean mixture.
Why electric cars will never work?
Electric cars are severely limited by several drawbacks, including: A shortage of charging stations. High electricity costs. Disappointing battery capacity that limits the distance the cars can be driven between charges.
Can hydrogen cars explode?
There’s no explosion involved. Despite its name, the hydrogen bomb uses deuterium and tritium. Neither of those elements is used in fuel cells, so you shouldn’t worry about exploding while driving down the highway.30 déc. 2020
Do hydrogen cars make noise?
In summary, hydrogen cars are quieter than conventional gasoline cars. They do have a definite, low-decibel sound due to their fuel cell systems, but overall tire and wind noise is likely to be higher than this anyway.18 déc. 2018
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.
Are hydrogen cars fast?
The all-wheel-drive car can go from zero to 60 miles per hour in a little over two seconds, the company said. Hydrogen fuel cell cars are electric cars that use hydrogen to generate power inside the car rather than using batteries to store energy.12 août 2020
Is hydrogen fuel the future?
Hydrogen is the fuel of the future. … Hydrogen is an energy carrier that can be used in internal combustion engines or fuel cells producing virtually no greenhouse gas emissions when combusted with oxygen. The only significant emission is water vapor.
Why is hydrogen dangerous?
Health effects of hydrogen Many reactions may cause fire or explosion. Explosion: Gas/air mixtures are explosive. Routes of exposure: The substance can be absorbed into the body by inhalation. Inhalation: High concentrations of this gas can cause an oxygen-deficient environment.
