Definition:
The simultaneous production of electricity and useful thermal energy from a single energy source, enhancing efficiency by utilizing the heat that would otherwise be wasted in power generation.
Key Components:
- Prime Mover: The main generator (gas turbine, steam turbine, or reciprocating engine).
- Heat Recovery System: Captures and repurposes excess thermal energy.
- Electricity Generation: Supplies power for industrial, commercial, or residential needs.
- Integration with District Heating: Can be used for heating multiple buildings or processes.
Use Cases/Industries:
- Industrial Plants: Using waste heat to generate additional power or steam.
- Hospitals & Universities: Ensuring reliable power and heating supply.
- Municipal District Heating Systems: Providing community-scale energy solutions.
Advantages:
- Improves Energy Efficiency: Can reach up to 80% efficiency compared to traditional power plants.
- Reduces Greenhouse Gas Emissions: Lowers carbon footprint by maximizing fuel use.
- Enhances Energy Security: Provides on-site power generation and backup capabilities.
Challenges:
- High Initial Investment: Requires specialized equipment and infrastructure.
- Complex System Integration: Needs tailored design for each application.
