Consider the following statements regarding green hydrogen production and its associated environmental constraints:

Statements

1. Green hydrogen is produced through electrolysis, a process that splits water molecules into hydrogen and oxygen using electricity derived from renewable sources such as solar or wind power.
2. The primary end-use sectors for green hydrogen are electricity generation and residential heating, as industrial sectors like steel manufacturing and chemical refining predominantly rely on grey hydrogen.
3. A fundamental tension in siting green hydrogen production in arid regions is that the zones with the highest renewable energy potential are often those with the most acute freshwater scarcity, creating a water-energy nexus constraint.
