Hydrogen Production Methods and Colors
Hydrogen is produced through various industrial processes, each with distinct advantages and environmental implications:
- Green Hydrogen: Produced via electrolysis, splitting water into hydrogen and oxygen using electricity from renewable sources like wind, solar, or hydro power.
- Turquoise Hydrogen: Generated through methane pyrolysis, breaking methane into hydrogen gas and solid carbon, which can be repurposed or stored without contributing to global warming.
- Blue Hydrogen: A "net-zero" version of grey hydrogen, where carbon dioxide from steam methane reforming is captured and sequestered using carbon capture and storage (CCS) technologies.
- Grey Hydrogen: Produced via steam methane reforming, emitting carbon dioxide as a byproduct, making it the least sustainable option.
