Pink Hydrogen is an ultra-low-carbon hydrogen produced through water electrolysis powered by nuclear energy. In this process, electricity generated from nuclear power plants—either existing baseload reactors or advanced small modular reactors (SMRs)—is used to split water molecules (H₂O) into hydrogen (H₂) and oxygen (O₂).
Because nuclear energy provides continuous, high-capacity, near-zero-emission electricity, Pink Hydrogen combines the purity and cleanliness of Green Hydrogen with the reliability and scale of baseload power.
This makes Pink Hydrogen a strategic clean-energy solution for hard-to-abate industries that require large, uninterrupted hydrogen supply while meeting net-zero and ESG commitments.
Nuclear-Powered Electrolysis Process
Reaction: 2H₂O → 2H₂ + O₂
- Electricity source: Nuclear power
- No fossil fuel combustion
- No CO₂ emissions during hydrogen production
Electrolyzer Technologies Used
- Alkaline Electrolyzers (AEL): Mature, cost-effective. Ideal for steady nuclear power output.
- PEM (Proton Exchange Membrane) Electrolyzers: Produces very high-purity hydrogen. Fast response and compact footprint.
- High-Temperature Electrolysis (SOEC): Uses nuclear heat + electricity. Highest efficiency among electrolysis methods. Strong synergy with nuclear reactors.
Integration with Nuclear Plants
- Uses off-peak nuclear electricity
- Improves plant load-factor economics
- Enables co-generation of power + hydrogen
- Reduces grid curtailment
