  • This study conducts economic evaluation of alternatives for $CO_2$ reduction of thermal power plants. Two alternatives in reducing $CO_2$ emission are considered for the evaluation under the RPS(Renewable Portfolio Standard) system; one is to perform renewable energy quotas and another is to construct green thermal power plants using CCS(Carbon Capture and Sequestration). As evaluation methods, DCF(Discount Cash Flow) and ROPM(Real Options Pricing Method) are employed. At a discount rate of 7.5% applied to the Electricity Supply and Demand Plan, it is shown that green thermal power generation has economic dominance under both evaluation methods.

  • Solar hot water system produces hot water using solar energy. If it is not used effectively, overheating occurs during the summer. Therefore, a lot of research is being done to solve this. This study develops thermoelectric power module applicable to solar hot water system. A thermoelectric material can directly convert thermal energy into electrical energy without additional power generation devices. If there is a temperature difference between high and low temperature, it generate power by Seebeck effect. The thermoelectric module generates electricity using temperature differences through the heat exchange of hot and cold water. The water used for cooling is heated and stored as hot water as it passes through the module. It can prevent overheating of Solar hot water system while producing power. The thermoelectric module consists of one absorption and two radiation part. There path is designed in the form of a water jacket. As a result, a temperature of the absorption part was $134.2^{\circ}C$ and the radiation part was $48.6^{\circ}C$. The temperature difference between the absorption and radiation was $85.6^{\circ}C$. Also, The Thermoelectric module produced about 122 W of irradiation at $708W/m^2$. At this time, power generation efficiency was 2.62% and hot water conversion efficiency was 62.46%.
