2. Combined Heat and Power (CHP)
What is CHP?
Efficient way to generate heat and power together
What does CHP provide to the rest of the project?
Electricity
Cooling water
Why is CHP needed?
Improves fuel efficiency
Cuts down energy cost
Reduces investment
Our Goal
“To optimize energy production and consumption of the whole plant .“ - Prof. Perl
