How hydrogen is produced
Hydrogen is not a new product, but the way that hydrogen is produced defines the carbon intensity of the hydrogen. Explore the many ways hydrogen can be produced.
Hydrogen production 101
Hydrogen is currently produced via a variety of methods, with the majority of worldwide hydrogen produced through the following carbon intensive processes:
Using fossil fuels in traditional industrial processes:
- Steam methane reformation of natural gas
- Coal degasification
- Partial oxidation reforming of hydrogen from hydrocarbons
As an industrial by-product:
- Chlorine plants, ethylene, plastics manufacturing
Hydrogen can also be produced in lower carbon intensive processes, but to date the production from these methodologies’ accounts for a very small amount of worldwide hydrogen production:
- Leveraging renewable and low-carbon electricity
- Electrolysis of water via electricity
- Methane pyrolysis
- Biomass gasification
What is carbon intensity?
Carbon intensity is a measure of a given fuel or commodities' greenhouse gas emissions associated with both producing and consuming the fuel. Typically, the carbon intensity of a fuel is measured in gCO2e/MJ.
Carbon intensities of typical fuels
~60- 96 gCO2e/MJ
* produced from fossil fuels
How does Atura plan on producing hydrogen at scale?
Atura plans to produce hydrogen via large-scale (20+ MW) electrolysis facilities using renewable and low-carbon electricity - resulting in significant green and low-carbon hydrogen.
Hydrogen with a very low carbon footprint provides the opportunity to displace other heavy emitting fuels or other higher carbon intensity hydrogen sources.
As the world moves toward net-zero, hydrogen will be a critical tool in the fight against climate change.
