Pink Hydrogen is an ultra-low-carbon hydrogen produced through water electrolysis powered by nuclear energy. Electricity generated from nuclear power plants is used to split water molecules (H₂O) into hydrogen (H₂) and oxygen (O₂).
Because nuclear energy delivers continuous, high-capacity, near-zero-emission electricity, Pink Hydrogen combines the purity of green hydrogen with the reliability and scale of baseload power.
Nuclear-Powered Electrolysis
2H₂O → 2H₂ + O₂
Electricity source: Nuclear power
No fossil fuel combustion and no CO₂ emissions during hydrogen production.
Electrolyzer Technologies Used
Alkaline Electrolyzers (AEL)
Mature and cost-effective, ideal for steady nuclear baseload output.
PEM Electrolyzers
Produce very high-purity hydrogen with compact footprint and fast response.
High-Temperature Electrolysis (SOEC)
Uses nuclear heat and electricity, offering the highest efficiency and strong reactor synergy.
Integration with Nuclear Plants
Utilizes off-peak nuclear electricity, improves plant load factors, enables co-generation of power and hydrogen, and reduces grid curtailment.
Key Characteristics
Ultra-Low Carbon Footprint
Lifecycle emissions are near zero and comparable to green hydrogen without weather dependency.
Exceptional Hydrogen Purity
Electrolysis delivers 99.99–99.999% purity, suitable for fuel cells, electronics, pharmaceuticals, and specialty chemicals.
Stable Baseload Supply
Nuclear power operates 24/7, enabling uninterrupted hydrogen supply for continuous industrial processes.
High Energy Density
Gravimetric energy density of 120–142 MJ/kg supports high-temperature processes and long-duration energy storage.
