Trigeneration (Electricity-Heat-Hydrogen)
Trigeneration is an energy technology that enables the production of electricity, heat and cooling within the same system. While conventional cogeneration systems only generate electricity and heat, trigeneration systems can additionally produce cooling or hydrogen.

Trigeneration systems based on renewable energy sources offer great advantages in terms of sustainable energy production. For example:
- Electricity generation: The system can generate electricity through generators using hydrogen or natural gas as fuel.
- Heat recovery: The waste heat generated during production can be used to heat buildings or industrial plants.
- Hydrogen production: Excess energy can be used to produce hydrogen by electrolysis of water. This hydrogen can be stored and used as fuel.
Trigeneration technology, which is widely used especially in large facilities, hospitals and industrial enterprises, plays an important role in creating a more sustainable energy infrastructure in the future.s
