Electrolysis

Definition:
A chemical process that uses electricity to split water into hydrogen and oxygen, producing hydrogen gas as a clean energy carrier.

Key Components:

• Electrolyzer Technology: Includes alkaline, proton exchange membrane (PEM), and solid oxide electrolyzers.
• Renewable Power Source: Wind, solar, or hydro energy drives the electrolysis process.
• Hydrogen Storage: Captures and stores produced hydrogen for later use.

Use Cases/Industries:

• Green Hydrogen Production: Enables zero-emission hydrogen fuel for various sectors.
• Chemical Industry: Used to produce ammonia and other essential chemicals.

Advantages:

• Zero Carbon Emissions: When powered by renewable energy, it produces clean hydrogen.
• Scalability: Can be deployed at small or large scales based on demand.

Challenges:

• High Electricity Demand: Requires large amounts of renewable energy.
• Costly Infrastructure: Electrolyzers and hydrogen storage systems involve high capital costs.
