Abstract
The present scenario of captive power generation has been outlined with the challenges and the future steps to be implemented. The developments of conventional and the latest power plants are presented. The literature is focused on organic Rankine cycle (ORC), organic flash cycle (OFC), Kalina cycle (KC), steam Rankine cycle (SRC), and steam flash cycle (SFC). The research gap is identified and highlighted the scope for future developments.
Keywords: Flash cycle, Kalina cycle, Organic rankine cycle, Thermal power plant, Waste heat recovery.
