This paper describes the results from a performance comparison of different types of HVAC systems in a low energy residential building. There were five different HVAC systems which were investigated and evaluated: Ground Couple Heat Pump (GCHP); Ground Water Heat Pump (GWHP); Air-to-Water Heat...

Renewable Energy Sources (RES) and especially wind energy are seen as an essential part of the future clean energy system. In the present paper, the wind potential of Kythira Island was studied and a techno-economic analysis was done aiming at identifying the optimum solution for the proposed...

Olefins are one of the most important oil derivatives widely used in industry. To reduce the dependence of olefins industry on oil, China is increasing the production of olefins from alternative energy resources, especially from coal. This study is concerned with the opportunities and obstacles...

With less than 6 mm of rain from November through February every year, the central regions of Nigeria are in acute need of safe and consistent water supplies for drinking and other domestic or agricultural uses. Borehole supplies are capable of meeting a significant proportion of water needs,...

Combined heat and power (CHP) plants dominate the heating market in China. With the ongoing energy structure reformation and increasing environmental concerns, we propose gas-fired boilers to be deployed in underperforming heating substations of heating networks for peak load compensation, in...

This analysis identifies the sensitivity of the fast pyrolysis and hydroprocessing pathway to facility location. The economic feasibility of a 2000 metric ton per day fast pyrolysis and hydroprocessing biorefinery is quantified based on 30 different state-specific facility locations within the...

CO2 emissions from distributed energy systems are expected to become increasingly significant, accounting for about 20% for current global energy-related CO2 emissions in 2030. This article reviews, assesses and compares the techno-economic performance of CO2 capture from distributed energy...

The solar thermal power plant is one of the promising renewable energy options to substitute the increasing demand of conventional energy. The cost per kW of solar power is higher and the overall efficiency of the system is lower. In the present communication, a comprehensive literature review...

Concentrating solar power plants represent a competitive option to produce electric power only if equipped with suitable thermal energy storage. Metal hydride material-based thermochemical hydrogen storage is a very attractive solution to store high temperature solar thermal energy. A literature...

A model for high temperature co-electrolysis (HTCE) of carbon dioxide and water using solid oxide electrolytic cells (SOEC) for syngas production and subsequent conversion to liquid fuels by a Fischer–Tropsch (F–T) process is presented. The SOEC model is guided by experimental data from the...
