The Colors of Hydrogen
Production Methods Green Hydrogen
Electrolysis + Renewable Energy
Water is split into hydrogen and oxygen using electricity from solar, wind, or other renewable sources. Zero carbon emissions in production. The cleanest pathway but currently the most expensive.
$4–$8
~0 kg/kg H₂
Scaling
~1%
Blue Hydrogen
Natural Gas + Carbon Capture
Produced via steam methane reforming (SMR) from natural gas, with carbon capture and storage (CCS) to reduce emissions. Cheaper than green but controversial: CCS capture rates vary widely (50-95%).
$1.50–$3
1–5 kg/kg H₂
Commercial

Pink Hydrogen
Electrolysis + Nuclear Power
Uses nuclear electricity for electrolysis. Very low carbon, using existing baseload nuclear plants. Sometimes called "red" or "purple" hydrogen. Growing interest as nuclear renaissance gains momentum.

Power Sector Applications
Grid IntegrationGas Turbine Blending
Hydrogen can be co-fired with natural gas in existing combustion turbines, reducing CO₂ emissions without requiring new infrastructure. Most modern turbines can handle 15–30% hydrogen by volume; some are designed for 100%.
GE Vernova: 100% H₂-capable HA turbines in development
Siemens Energy: Turbines operating at up to 75% H₂ blend
Mitsubishi Power: Targeting 100% H₂ by 2030
Impact: 30% H₂ blend = ~10% CO₂ reduction

Hydrogen Fuel Cells
Proton exchange membrane (PEM) and solid oxide fuel cells convert hydrogen directly to electricity with high efficiency. Ideal for backup power, peaking, and distributed generation at data centers and critical facilities.
Efficiency: 40–60% (simple), 70–75% (hybrid)
Bloom Energy: Solid oxide fuel cells for data centers
Plug Power: PEM systems for industrial/backup
Use case: Replacing diesel backup generators

Long-Duration Energy Storage
Hydrogen excels at multi-day and seasonal energy storage, far beyond lithium-ion's 4-hour sweet spot. Surplus renewable energy makes hydrogen via electrolysis; stored H₂ generates power when demand peaks or wind/solar drops.
ACES Delta (Utah): Salt cavern H₂ storage for CAES
Duration: Days to seasonal (vs 4hr Li-ion)
Storage: Salt caverns, pipelines, tanks
Cost: <$500/kW using automotive fuel cells

Industrial Cogeneration
Combined heat and power (CHP) systems using hydrogen can simultaneously provide process heat and electricity for industrial facilities, refineries, chemical plants, steel mills, while slashing emissions.
Efficiency: Up to 80% (CHP mode)
