Until now, a small number of studies have analysed the carbon footprint (CO2 eq. emissions) of the application of Phase Change Materials (PCMs) in conventional Thermal Energy Storage (TES) systems considering different conventional fossil fuels as the source of heat. In those scarce studies, the...

We present exergy and economic analyses of two advanced fossil fuel power plants configurations: an integrated gasification combined cycle with advanced H2 and O2 membrane separation including CO2 sequestration (Adv. IGCC–CCS) and an integrated gasification fuel cell cycle with a catalytic...

The supply security of fossil fuels is one of the most important policy issues in South Korea. This is because of South Korea’s economic condition, geopolitical status, and lack of energy resources. This study investigates the Korean public’s perceptions of the supply security of fossil...

Recent environmental regulatory sharp curbs on fossil fuel power plants have obliged industries to incorporate alternative sources of fuels for energy production. Cost and recovery of synthetic catalysts are major challenges in carbonaceous materials catalytic gasification. Biomass rich in...

Many recent patents worldwide address the concept of harvesting wind energy from aerodynamic losses in motorways, however the mechanics of a specific device dedicated to the task has never been described. The lack of a characterization of the energy resource likely explains why the international...

The collective behavior of wind farms in seven Independent System Operator (ISO) areas has been studied. The generation duration curves for each ISO show that there is no aggregated power for some fraction of time. Aggregation of wind turbines mitigates intermittency to some extent, but in each...

Wind turbine wakes have significant effects on the production efficiency and fatigue loads, and these effects should be considered in the optimization of wind turbine structure and wind farm layouts. In this paper, a numerical model combining Lagrangian dynamic large-eddy models and actuator...

Short duration wind variations affect real time performance of active pitch-regulated wind turbines in two ways as evident from reported experimental and empirical studies. First the mean output power, which may be referred to as the short duration output power, differs significantly from the...

There is considerable interest concerning sustainable, economically competitive and environmentally benign hydrogen production pathways. In this study, a large scale wind-hydrogen plant is assessed for the production of electrolytic hydrogen, for the servicing of the oil sands bitumen upgrading...

Ireland is currently striving to achieve an ambitious target of supplying 40% of electricity demand with renewable energy by 2020. With the vast majority of this being met by wind energy, an intermittent and non-dispatchable energy source, it is inevitable that frequent substantial curtailment...
