Biogas, Waste heat, ORC processAbstract
The aim of this paper is to analyze the potential of biogas use in cogeneration plants and its role in enhancing energy production efficiency through the ORC (Organic Rankine Cycle) process. Biogas, as a renewable resource, can be efficiently combusted to generate energy and waste heat. Instead of being lost, the waste heat can be utilized to produce additional amounts of energy using the ORC cycle. Although these concepts are distinct, their synergy offers significant advantages in terms of energy efficiency.
