Water electrolysis produces hydrogen with an efficiency of 52% with a corresponding cost of 10.3 $/kg. Water electrolysis faces the challenges of hydrogen production in a cost-competitive way, with a specific cost (€/kW) compatible with market and fiscal requirements.
Hydrogen can be produced using a number of different processes. Thermochemical processes use heat and chemical reactions to release hydrogen from organic materials,
Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700°C–1,000°C) is used to produce hydrogen from a methane source, such as natural gas. In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1

Let''s take a look at the hydrogen demand scenario from the "Hydrogen Scaling Up" report 1: the world currently produces 8 EJ (or 56 million tons) of hydrogen and would need 78 EJ by 2050 (or 550 million tons).A ten folds increase in 35 years. Today, about 95% of the production of hydrogen comes from fossil fuels: steam reforming,

You have to throw some energy away to make hydrogen – typically around 20-30%, even with the best systems, which use around 52.5 kWh of energy to create a kilogram of hydrogen that can store 39.
In 1931, Harold Urey and his colleagues at Columbia University in the US detected a second, rarer, form of hydrogen. This has twice the mass of normal hydrogen, and they named it deuterium. Glossary. Atomic radius, non-bonded Production concentration. The percentage of an element produced in the top producing country. The higher the value
