Definition:
The practice of injecting hydrogen into existing natural gas pipelines to reduce carbon emissions from natural gas combustion.
Key Components:
- Blending Facilities: Infrastructure that mixes hydrogen with natural gas at precise ratios.
- End-Use Adaptation: Modifications in appliances and power plants to handle blended fuels.
- Pipeline Material Compatibility: Ensures that existing infrastructure can safely transport hydrogen-mixed gas.
Use Cases/Industries:
- Residential Heating: Lowering emissions in household heating systems.
- Power Generation: Reducing carbon footprint in gas-fired power plants.
Advantages:
- Leverages Existing Infrastructure: Uses current gas networks to introduce hydrogen at lower costs.
- Immediate Carbon Reduction: Lowers CO₂ emissions from traditional gas use.
Challenges:
- Blending Limits: High hydrogen concentrations may require infrastructure upgrades.
- End-User Compatibility: Some gas appliances may need modifications to handle hydrogen blends.
