Trigeneration is a technology that simultaneously produces electricity, heat, and cooling, boosting energy efficiency up to 90% while reducing costs and emissions. It’s ideal for sectors with high energy demands and continuous cooling needs.
Trigeneration systems represent an advanced evolution of cogeneration technology. While cogeneration simultaneously produces electricity and heat from a single fuel source—typically natural gas—trigeneration adds a third component: cooling. This integrated approach maximizes energy recovery and minimizes waste, offering significant benefits for both industrial and civil applications.
How Trigeneration Works
The core of a trigeneration system is a cogenerator, generally powered by natural gas, which produces electricity. During this process, substantial thermal energy is also generated. Instead of being dispersed or underutilized, this heat is recovered and redirected to an absorption chiller. This machine uses natural refrigerants—most commonly ammonia or lithium bromide—to convert thermal energy into refrigeration.
Depending on the configuration and application, the resulting cooling output may take the form of:
- Chilled water
- Water-glycol mixtures
- Condensed ammonia at temperatures as low as –40°C
This makes trigeneration highly versatile and suitable for facilities that require simultaneous electrical, thermal, and cooling loads—such as food processing plants, hospitals, commercial buildings, and large manufacturing operations.
Key Benefits
- High overall efficiency: Trigeneration can achieve efficiency rates of up to 90%, far exceeding separate production systems.
- Cost reduction: Integrated energy production lowers fuel consumption and operating costs.
- Environmental sustainability: Lower CO₂ emissions and optimized use of natural refrigerants support broader decarbonization goals.
- Operational flexibility: Cooling demand in summer months makes trigeneration ideal for year-round utilization.
Why Trigeneration Matters
In the context of rising energy costs and increased pressure for environmental responsibility, trigeneration offers a pragmatic solution for energy-intensive sectors. It transforms what was once a by-product, heat, into an asset, aligning energy efficiency with sustainable development.
