How much does it cost to produce 1 kg of 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.
How long does it take to produce 1kg of hydrogen?
MRE electrolyzers require 48 kilowatt hours (KWH) of electricity to produce 1 kg of hydrogen. More energy is required to compress and purify the hydrogen ranging from 5 to 15 KWH per kg, dependent on size of system. A fuel cell’s efficiency, on average, is about 55\%.
How far can a car travel on 1 kg of hydrogen?
In any of the latest fuel cell cars, 1 kg of hydrogen will let you drive 97 – 100 km.
How much hydrogen can be extracted from a Litre of water?
One liter of water will thus produce 111/0.0899 =1235 liters of hydrogen and 888.81/1.429 = 622 liters of oxygen. Note that according to Avogadro’s law, the volume of hydrogen is about twice that of oxygen, because 1 mol of water produces 1 mol of hydrogen and 1/2 mol of oxygen.
How much water is needed to produce 60 billion hydrogen gases?
Based on the atomic properties of water, 1 kg of hydrogen gas requires about 2.4 gallons of water as feedstock. In one year, 60 billion kilograms of hydrogen would require 143 billion gallons of fresh, distilled water.
How many grams of hydrogen are in a cup of water?
Hydrogen therefore is about 26.3 grams of the cup of water. How much hydrogen does a gallon of water make? In general, it takes about 50 kiloWatt hours of energy to electrolyze 9 kilograms (also 9 liters) of water to produce 1 kg of hydrogen (H2) and 8 kg of oxygen (O2). and 8 times as much or 3.324 kg of O2 per gallon of water.
How many litres is 1kg of hydrogen?
How many Litres is 1kg of hydrogen? Weight Liquid pounds (lb) liters (l) 1 pound 1.0 6.408 1 kilogram 2 How much hydrogen is in a cup of water
How much water does electrolysis of hydrogen use?
Looking at hydrogen production, the minimum water electrolysis can consume is about 9 kg of water per kg of hydrogen. However, taking into account the process of water de-mineralisation, the ratio can range between 18 kg and 24 kg of water per kg of hydrogen or even up to 25.7-30.2 according to [1].
