Definition:
Chemical compounds that store and transport hydrogen in a stable form, such as ammonia, methanol, or liquid organic hydrogen carriers (LOHCs).
Key Components:
- Ammonia (NH₃): Can store and transport hydrogen efficiently with existing infrastructure.
- Methanol (CH₃OH): Used as a hydrogen-rich fuel that can be reformed into pure hydrogen.
- Liquid Organic Hydrogen Carriers (LOHCs): Organic compounds that can reversibly bind and release hydrogen.
Use Cases/Industries:
- International Hydrogen Trade: Enables large-scale hydrogen transport across continents.
- Hydrogen Power Generation: Carrier molecules can be converted back into hydrogen for fuel cells.
- Maritime and Heavy Transport: Used as a clean fuel alternative for ships and trucks.
Advantages:
- Safe and Stable Storage: Reduces risks of hydrogen leaks or volatility.
- Utilizes Existing Infrastructure: Ammonia and methanol transport networks are already in place.
Challenges:
- Energy Conversion Losses: Extracting hydrogen from carriers requires additional processing.
- Toxicity Concerns: Some carriers, like ammonia, require strict handling and safety measures.
