Wind and solar energy are currently the most promising carbon free sources of electrical energy. However, high penetration of solar and wind into the electrical grid will require energy storage due to the intermittent and unpredictable nature of these sources. Using the Midcontinent Independent System Operator (MISO) energy market in the central region of the United States for the years 2007, 2008,...
Renewable energy gain a lot of attention due to rapid energy consumption growth and environmental issue especially solar power. This paper aim to present the designed and analysis of solar water pump to replace conventional diesel water pump that agriculturist currently used. The prototypes of solar water pump have been built and installed at southern province of Thailand. The prototype of proposed...
In this paper, a low-cost and real-time remote monitoring system is proposed to continuously monitor the output performance and operation status of the distributed wind power plant. This system is based on the LoRa network to monitor those parameters related to the output performance and operation status of the wind turbine. The man-machine interface is designed with LabVIEW software to monitor the...
Peak demand has been increasing in recent years due to the population growth, new technologies and user preferences. Besides, the cost of electricity is considerably higher than other type of energies. For this reason, it is necessary to pay attention to the consumption of electricity. Increase in energy costs and energy demand has also made energy efficiency compulsory. Electrical appliances and...
Lignocellulosic-based bioethanol is providing one window of potential alternative energy. Pretreatment is one of the steps in the bioconversion of lignocellulosic material. The pretreatment process was conducted in a 5-liter reactor at 150 °C, 4 bars of pressure during 30 minutes. The SSF was carried out using 30 FPU cellulase enzyme and yeast Saccharomyces cerevisiae. The delignification of pretreatment...
This paper presents an application of Genetic Algorithm (GA) to solve Economic Load Dispatch problem which aims to determine minimum fuel cost and Environmental Load Dispatch problem which aims to determine minimum gas emission for required energy production of the chosen power system. Test system is chosen as IEEE-30 bus system which includes 6 generators with necessary values given for ease of simulation...
The effect of building envelope (walls and fenestration) on the thermal comfort of the residential buildings in Egypt is the main concern for the authors' recent research work. The “the Egyptian residential energy code for improving energy efficiency” was taken as a guide to get the optimal energy performance and indoor thermal comfort. This paper presents the results of testing all the different...
Lignocellulosic plant biomass is a renewable starting material for sustainable production of fuels, chemicals, and materials with advantages on its carbon-neutral nature. Fractionation of lignocellulosic components is a pre-requisite in an integrated biorefinery process in order to convert the cellulose, hemicellulose, and lignin to respective products with maximized economics. In this study, a modified...
The design of fully-glazed façades on buildings has become very popular, especially in hot regions where the use of natural ventilation is not recommended. The integration of shading devices to façade surfaces has been extensively studied to mitigate the resulting increase in cooling load due to larger glazed areas. In this paper, the effect of double and triple-glazed façades oriented in the south...
The aim of this paper is to investigate the effect of 5% butanol with biodiesel-diesel blends on the performance, emission, and combustion of a naturally aspirated multi-cylinder diesel engine at different engine speeds and full load conditions. Three types of local Australian biodiesel namely macadamia biodiesel (MB) were used for this study, and the data was compared with conventional diesel fuel...
A research on the manufacture of polyurethane-based palm oil for materials paint coating with the addition of montmorillonite nanoparticles as a filler of heat-resistant polyurethane paint and chitosan for antimicrobial the material. The processing of bentonite to be montmorillonite through several stages including: sedimentation, ultra-sonication, dried, sieved with a 200 mesh sieve, and then characterized...
Silica slurry flow is multiphase flow consist of liquid and solid particles. Some parameters such as pipe geometry, particle solid size, percentage and density of solid concentration effect flow performance. Drag Reducing Agents (DRA) is one of the method to improve flow efficiency that used as agents to reduce power losses in pipeline. Biopolymer is one of the popular DRA due to environmental friendly...
Aviation pollutants emmissions are a nowadays high concern. Biofuels can be used to reduce fossil fuels dependence, especially the ones that does not require adaptation of the fuel distribution network nor the engine fuel systems. A Computational Fluid Dynamics (CFD) simulation of a CFM56-3 combustor burning Jet-A and a 100% blend of biofuels, was performed. Viability of use of these biofuels was...
