Cogenerations with reciprocating engines are highly efficient. With maximum use of the potential of the technology, an overall fuel efficiency of over 90% can be expected.
An important energy issue is ensuring security and flexibility of energy supply complementary to renewable sources. For such purposes, you need investment-friendly yet highly flexible technologies that provide capacity when the wind is not blowing or the sun is not shining.
A great advantage and a very widespread possibility is the combustion of biogas generated by anaerobic digestion of organic materials (waste).
