Pink hydrogen, produced through electrolysis powered by nuclear energy, is emerging as a promising clean power solution in India’s energy sector.
About Pink Hydrogen:
- Pink hydrogen refers to hydrogen, which is produced through electrolysis powered by nuclear energy.
- Nuclear-produced hydrogen can also be referred to as purple hydrogen or red hydrogen.
- In addition, the very high temperatures from nuclear reactors could be used in other hydrogen productions by producing steam for more efficient electrolysis or fossil gas-based steam methane reforming.
- The entire system is low carbon due to the absence of carbon in water, and the energy source is also very low carbon because it is nuclear.
Different types of hydrogen based on their production methods:
| Color | Production Method | Energy Source | CO2 Emissions |
| Green | Electrolysis of water | Renewable sources | None |
| Blue | Steam methane reforming (SMR) or autothermal reforming (ATR) | Natural gas | Captured/stored (Use of carbon capture and storage (CCS)) |
| Grey | Steam methane reforming (SMR) or autothermal reforming (ATR) | Natural gas | Released (Does not capture GHG made in the process) |
| Turquoise | Methane pyrolysis | Natural gas | Solid carbon |
| Yellow | Electrolysis of water | Solar energy | None |
| Pink (Red) | Electrolysis of water | Nuclear power | Low/none |
| Brown/Black | Gasification of coal | Coal | High |
