How much electricity does it take to create 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.
How much does it cost to produce 1 gallon of hydrogen?
Hydrogen is measured by the kilogram. 1 kilogram is 1 gallon of gasoline equivalent (gge). 2. $0.0015/gallon + $0.987/kg (gge) Refining Costs = $0.9885 = $1.00/kg (gge) using Atmospheric Electrolyses.

How much energy is in a gallon of hydrogen?
The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 kilograms) of gasoline. Because hydrogen has a low volumetric energy density, it is stored onboard a vehicle as a compressed gas to achieve the driving range of conventional vehicles.
Is it cost effective to produce hydrogen?
Overall, this data shows that hydrogen can be produced today within a cost range of ~$2.50 – $6.80/kg from a mix of renewable and grid feedstocks. This is in good alignment with the DOE analysis, which shows that hydrogen can be produced via PEM electrolysis at a cost of ~$4 to $6/kg for specific conditions.
Is hydrogen cheaper than gasoline?
Considerations. While hydrogen is a cheaper fuel than gasoline on paper, the reality is, as of 2010, it is much more expensive. The few models of hydrogen-fueled cars that are commercially available generally cost more than $100,000. Researchers are still tweaking the technology to produce and transport hydrogen fuel.
How efficient is a hydrogen fuel cell?
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.
Is green hydrogen cost effective?
In the short-term, green hydrogen costs are being reported in the range of 2.5-6 USD/kg H2. In most cases this means green hydrogen is more expensive than both grey and blue, but at the lower end of the range it is cost-competitive with blue.

Hydrogen Fuel Cost vs Gasoline
$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 …
Hydrogen economy – Wikipedia
The hydrogen economy is using hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the “hard-to-abate” sectors such as cement, …
How Much Will Hydrogen-Based Power Cost?
If this hydrogen is used to generate power, the resulting cost is $100 to $200/MWh. In ideal conditions (e.g. a CCGT turbine at 60% utilisation) …
Why use hydrogen fueling stations – Millennium Reign Energy
Hydrogen Conversion Information · 423 standard cubic feet (scf) = 1 kilogram (kg) of hydrogen. · It takes 2.3 gallons of water to create 1 kg of hydrogen. · There …
Why is hydrogen fuel so expensive?
Because hydrogen contains less energy per unit volume than all other fuels, transporting, storing, and delivering it to the point of end-use is more expensive on a per gasoline gallon equivalent basis.
Why is green hydrogen so expensive?
High cost: energy from renewable sources, which are key to generating green hydrogen through electrolysis, is more expensive to generate, which in turn makes hydrogen more expensive to obtain.
Why hydrogen is not a good fuel?
But it is not used as domestic fuel, due to several reasons : Hydrogen is not easily available and cost of production is high Unlike other gases, hydrogen is not readily available in the atmosphere. It requires processes like electrolysis of water for its production. This is a very costly process and time consuming.
Is hydrogen more efficient 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.
Is hydrogen more efficient than natural gas?
Whereas natural gas and electricity are roughly the same cost and efficiency to distribute on a per unit energy basis, hydrogen is going to cost about 3× what natural gas costs in lost energy, just to move the gas.
Hydrogen – the Fuel of the Future?

What is the cheapest way to produce hydrogen?
Steam methane reforming (SMR) is a method of producing hydrogen from natural gas, which is mostly methane (CH4). It is currently the cheapest source of industrial hydrogen. Nearly 50% of the world’s hydrogen is being produced by this method.
What is the main problem in using hydrogen as fuel for vehicles?
Explanation: The main problem in using hydrogen as fuel for vehicles is storage of hydrogen. Hydrogen is difficult to store because it leaks easily. Moreover, it is extremely hazardous as fuel due to its low ignition temperature and high combustion energy.
How much can you sell hydrogen for?
Taking into account 2021 wind and solar costs, most planned green hydrogen projects will end up with a hydrogen selling price between 3.18 and 5.75 U.S. dollars per kilogram.
Is Tesla making a hydrogen car?
The Tesla Model 2 will now be hydrogen-powered. Tesla insiders claim the Model H will be followed in 2025 by the much-anticipated Model 2, which will now also run on hydrogen, providing an expected 400-mile range in a compact hatchback form.
Why is Elon Musk against hydrogen?
Far too expensive, inefficient, slow and difficult to rollout and transport. After all: no #hydrogen cars in sight.” Musk and Diess are two high-profile figures at the helm of major companies with huge influence and reach.
Will hydrogen cars overtake electric?
That’s true to an extent, but hydrogen-powered cars are not really expected to replace EVs. Instead, hydrogen is intended to complement pure electric power, and there’s a good reason for this: it is the cleanest fuel possible.
Is hydrogen cheaper than electric?
Electric vehicles are also cheaper than hydrogen powered cars, while the cost of recharging is also less during off-peak grid times, making electric vehicles a good long-term investment.
How much electricity can a hydrogen fuel cell produce?
This cell uses high operating temperatures of around 650 °C and can create an electrical output of up to three megawatts (a megawatt is 1,000 kW or 100,000 watts).
Do hydrogen powered cars need batteries?
Just as traditional internal combustion engine powered vehicles need batteries, so do fuel cell vehicles. Even though hydrogen cars produce their own electricity through their fuel cells, it’s still necessary that a buffer be in place in the form of a small high-voltage battery.
Is grey hydrogen cheap?
It notes that a kilogram of grey hydrogen currently costs 6.71 US dollars in these regions compared to 4.84 to 6.68 dollars per kilogram for green hydrogen – due mainly to the price of gas, which has been climbing since the end of last year and shot up significantly with the Russian attack on Ukraine.
Hydrogen Home Storage. Could this be a game changer?

Is Blue hydrogen cheaper than green hydrogen?
New research predicts that green hydrogen — a clean fuel produced from water using renewables — will be comparable in cost and likely cheaper than blue hydrogen by 2030.
How much does grey hydrogen cost?
Gray hydrogen produced with cheap fracked natural gas costs US$2 per kg in the US, while in Europe, Australia and Asia it costs US$5-6 per kg due to higher natural gas prices.
