Hydrogen Fuel and Green Hydrogen Production

The process of generating hydrogen as an energy carrier, particularly through electrolysis using renewable electricity, to create zero-emission fuel.

Key Components:

• Electrolysis: Splitting water into hydrogen and oxygen using electricity.
• Hydrogen Storage: Compressing or liquefying hydrogen for transport and use.
• Fuel Cells: Converting hydrogen into electricity through an electrochemical process.

Use Cases/Industries:

• Transportation: Powering fuel cell electric vehicles (FCEVs) such as buses, trucks, and ships.
• Industrial Applications: Replacing fossil fuels in steel production, ammonia manufacturing, and refining.
• Energy Storage: Acting as a long-term energy carrier for excess renewable power.

Advantages:

• Zero Carbon Emissions: Green hydrogen produces only water vapor when used in fuel cells.
• Versatile Energy Carrier: Can be stored and transported for multiple applications.
• Supports Decarbonization: Enables deep emission reductions in hard-to-electrify sectors.

Challenges:

• High Production Costs: Electrolysis requires significant amounts of electricity, making green hydrogen costly.
• Infrastructure Limitations: Requires new storage, transport, and distribution networks.
• Energy Losses: Efficiency losses occur during hydrogen production, storage, and conversion.
