Electricity Generation from Exhaust Steam of a Steam Turbine Generator

Abstract

The world desperately needs renewable energy. Harnessing energy from waste heat has the potential of bringing in a new era of electricity. This paper explores the utilization of waste heat through the implementation of a Peltier module-based electricity generation system. The proposed system employs Thermoelectric Generators (TEGs), leveraging the Seebeck effect, to convert thermal energy differentials into electric voltage. Through a detailed examination of the system's design, implementation methodology, and experimental results, the paper clarifies the feasibility and efficiency of Peltier-based electricity generation, including a scenario involving a 100 MW Diesel Power Plant that demonstrates the scalability and practical applications of the system. In this article, we utilized 750 ml water to create a total of 201.8256 mWh of energy from three Peltier modules. 12V Peltier modules were utilized in the planned system and predicted with 2L of water to create a maximum of 11.18 V, 9.67 V, and 7.23 V into three distinct Peltier modules. Data analysis and forecasting models provide insights into system performance and limitations under varying conditions. Ethical considerations regarding sustainability, material procurement, and disposal are also discussed. The paper underscores the promise of Peltier-based electricity generation in harnessing waste heat for sustainable energy solutions while emphasizing the importance of ethical awareness in technology deployment.
