Abstract

It has, in recent times, become the focus of national and international political pressure to reduce the impact of climate change [1]. The amount of CO2 that is released to the atmosphere now has legislative and tax implications with CO2 emitters around the world in both developed and developing countries having to implement CO2 reducing technologies to reduce costs and maintain profitability [2]. We aim to exploit the Peltier effect exhibited in semiconductor devices to create an enthalpy capture device using the significant amount of energy rejected by such a power plant. A thermoelectric device applied in its heat pumping mode, enables the redirection of energy released in the condensation process. We aim to prove that using the thermoelectric device in a particular configuration enables the preheating of water returning to the boiler (feed water). Such an application of a heat pumping device will increase the net efficiency of the Rankine cycle.
