exploring the potential for improvement of the energy performance of coal fired Power Plants with post combustion capture of carbon dioxide
International Journal of Greenhouse Gas Control, 2010Co-Authors: Paul FeronAbstract:Abstract The application of post-combustion capture (PCC) processes in coal fired Power stations can result in large reductions of the CO 2 -emissions, but the consequential decrease in generation efficiency is an important draw-back. The leading PCC Technology is based on chemical absorption processes as this Technology is the one whose scale-up status is closest to full-scale capture in Power Plants. The energy performance of this process is analysed in this contribution. The analysis shows that the potential for improvement of the energy performance is quite large. It is demonstrated that further development of the capture Technology and the Power Plant Technology can lead to generation efficiencies for Power Plants with 90% CO 2 capture which are equivalent to the current generation efficiencies without CO 2 capture, i.e. 0.4 (HHV), leading to an additional resource consumption of 16%. These improvements are possible throughout a combined improvement for the capture process and Power generation processes.

Geothermal energy: Power Plant Technology and direct heat applications
Renewable and Sustainable Energy Reviews, 2018Co-Authors: Diego Moya, Clay Aldás, Prasad KaparajuAbstract:The transition from current fossil-fuel energy system towards a sustainable one-based requires renewable energy Technology. Although geothermal energy presents its own particular challenges in comparison with other renewable energy technologies, geothermal energy has showed significant potential to reduce environmental impact and greenhouse gas emissions from electricity production. Advantages of geothermal energy are not only the generation of electricity in different Plant configurations but also the direct application of heat in industry and household uses regardless of meteorological conditions. In this study, a research review is carried out on the aspect of geothermal energy development, assessing Power Plant Technology and direct heat applications. Five Power Plant configurations are studied: single-flash, double-flash, dry-steam, binary and advanced. The thermodynamic aspects are addressed in order to consider them for future geothermal Power Plant analysis. Furthermore, the most common direct uses of geothermal heat are discussed. Results illustrate that Binary – Organic Ranking Cycle Power Plants might play a vital role in the exploitation of low temperature geothermal resources. Furthermore, it is identified a need for research in hybrid geothermal-solar-biomass configurations for poly-generation purposes. These configurations increase the energy output, increasing the thermal efficiency and increasing the life of the geothermal reservoir. Similarly, direct applications of geothermal heat present good opportunities for increasing the revenue of a geothermal project. Depending of the geographic zone, cascade configurations contributes to maximise the use of geothermal resources. Future research reviews should consider the financial, economic and policy aspects of geothermal developments along with the geology, geophysics, geochemistry, drilling, reservoir engineering and environmental aspects. The main goal of addressing these topics is to provide the state-of-the-art of geothermal development for developers, policy makers, researchers and communities interested in geothermal energy.

solar updraft tower Power generation
Solar Energy, 2016Co-Authors: Xinping Zhou, Yangyang XuAbstract:Abstract Solar updraft tower Power generation has been demonstrated to be a promising approach for future applications of solar radiation to provide energy. In this paper, the history of the solar updraft tower Power Plant (SUTPP, also called solar chimney Power Plant) Technology is reviewed, its characteristics are presented, and its principle is described. The experimental studies, main important factors of theoretical modelings, and cost studies, in the past few decades, are reviewed. The characteristics of novel non-conventional SUTPP technologies are discussed as well as environmental effect and Power production conditions for the SUTPP Technology.
