The retail competition in electrical power industry may produce benefits in perspectives of both business and environment. Customers can obtain monetary benefits through competition among service providers and exploit diverse electric services which can be more enhanced with the retail...

Energy flow from the primary energy to the final energy use varies depending on which device is used for the heating and cooling energy service. This paper presents economic analyses of medium capacity space heating and cooling systems from three perspectives – primary energy, final consumer,...

The contribution of the molten carbonate fuel cell system (MCFCs) to carbon dioxide (CO2) emission reduction in power application is analyzed. MCFCs can separate and concentrate CO2 emitted from traditional thermal power plants (PPs) without reducing the plant's overall energy efficiency. MCFCs...

This work reviews the availability and the potential of the carbon capture and storage (CCS) technology using coal fly ash (FA). Because the technology can be effectively applied on-site to coal fired power plants and as FA contains sufficient alkali components, the technology may be another...

Molten carbonate fuel cell (MCFC)/gas turbine (GT) hybrid system has attracted a great deal of research effort due to its higher electricity efficiency. However, its technology has remained at the conceptual level due to incomplete examination of the related issues, challenges and variables. To...

The present paper analyzes the CO2 emissions from mobile communications and portable wireless electronic devices in the Korea environment. The quantitative and qualitative contributions to CO2 emission reduction of the substitution of renewable energy for traditional electricity as the power...

Fuel cells (FCs) and their hybrid systems can play a key role in reducing carbon dioxide (CO2) emissions. The present paper analyzes the contributions of the FC system to CO2 emission reduction in three application fields. In the mobile application field, the direct methanol FC system has little...

Proton exchange membrane fuel cells (PEMFCs) have recently passed the test or demonstration phase and have partially reached the commercialization stage due to the impressive worldwide research effort. Despite the currently promising achievements and the plausible prospects of PEMFCs, there are...

The present paper investigates the application of raw coal fly ash (FA) to dry-based CO2 fixation. Dry sorbents are manufactured by mixing FA, NaOH, CaO and a small amount of water and their absorption behavior, performance, regeneration and leaching efficiency are analyzed. The CO2 absorption...
