+ How is hydrogen made?
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.

+ How much does hydrogen cost?
Our experience and sources claim hydrogen fuel costs between 5 to 20 euros per kilogram. This is excluding storage, fuel cells or generators. Check out our section on costs for more (click here).
+ Under what pressure is hydrogen stored? How does the pvT diagram look?
Dependent on your application, hydrogen can be stored ranging from low pressure (100-200 bar) and room temperature, to high pressure (up to 750 bar for cars and beyond in specialized cases) or even in cryogenic state (around -200 degrees Celsius and up to 1000 bar). The full pvT diagram is shown below.
+ Where can I buy hydrogen or related products?
We are working on a database of hydrogen suppliers, fabricators, knowledge centers and more. For now, we have the following list of stakeholders active in hydrogen industry, mostly active in engineering and design but also fabrication and/or supply of hydrogen:
