Section 2 of 5How Hydrogen is Produced
Hydrogen production methods vary widely in their environmental impact, energy efficiency, and cost. The choice of production method determines whether hydrogen contributes to climate solutions or exacerbates environmental challenges.
Today, most hydrogen is produced through steam methane reforming of natural gas, a process that releases significant CO₂ emissions. However, electrolysis powered by renewable energy offers a pathway to truly clean hydrogen production.
The Color Coding System
Hydrogen is often categorized by color: gray (from fossil fuels), blue (with carbon capture), and green (from renewables). Understanding these differences is crucial for building a sustainable hydrogen economy.

Water Electrolysis
Using electricity to split water molecules - produces green hydrogen when powered by renewables
Steam Methane Reforming
Reforming natural gas with steam - current dominant method but produces CO₂
Coal Gasification
Gasifying coal to produce hydrogen - high emissions but established technology
Biomass Gasification
Using biomass for hydrogen production - carbon-neutral if sustainable sourcing
Photoelectrolysis
Direct water splitting using sunlight - emerging technology with high potential
The Path to Green Hydrogen
While steam methane reforming dominates today, electrolysis powered by renewable energy offers the cleanest path forward. The challenge is scaling green hydrogen production to meet growing demand while reducing costs.
