CHP: 3 primary criteria for successfull cogeneration projects in power plants

On world average only 9% of electricity production comes from cogeneration or CHP. However, some countries are well above. For instance, Denmark has more than 60%.

Cogeneration can not only deliver economic benefits but also environmental ones (avoiding CO2 emissions). If that is the case, why are not more countries reaching the level of Denmark?

This paper describes the three main criteria…
