Energy cost

Turbines are the most common devices used in the field of wind energy and tidal energy. They are also the main research objectives of scientists worldwide. Different research methods are applied to study these devices, including the numerical simulation method. This is an advanced approach that helps to save costs of calculation, but it still keeps the accuracy.

The replacement of noble metals in homogeneous catalysts for the current CO2 hydrogenation reaction with 3D transition metals (Fe, Co, Ni and Mn), with lower costs, have attracted a great attention of many research groups to the interconversion of chemical and electrical energy, like CO2 and H2.

The Adsorption – desorption is considered as one of the most promising VOCs treatment technologies due to its cheap operational cost and low energy consumption. However, there are a huge amount of adsorbed VOCs released in desorption process. That is the reason why this study focused on the combination of adsorption-desorption with catalytic oxidation to treat completely VOCs as toluene.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.

Several studies have been carried out by optimising only the cost. They have not considered some other risk factors such as political and economic factors in their modelling. Currently, there is no generalised model available to determine the optimal sourcing locations incorporating important factors including risks in international LNG trading. In this study, 12 risk factors were taken into consideration to evaluate the risk.

Pig farming generates highly polluting wastewaters which entail serious environmental issues when not adequately managed. Microalgae systems can be promising for cost, energy and environment-efficient treatment of piggery wastewater (PWW). Aside from clean water, the produced biomass can be used as biostimulants and biopesticides contributing to a more sustainable agriculture.

The study uses data of a period 1968-2014 and cointegration test and corroborates a long- and short-run relationships. The results indicate that economic growth and energy consumption contributes in CO2 emissions in both long- and short-run. It means that increasing economic growth of the Kingdom has social cost on the economy in terms of pollution emissions. Based on findings, we recommend to use the alternative renewable sources of energy consumption to avoid the pollution effects of growth in Saudi Arabia.

The reactions form chains and rings of alumino-silicate networks in geopolymeric structures. The raw materials used for geopolymerization normally contain high SiO2 and Al2O3 in the chemical compositions such as meta-kaoline, rice husk ash, fly ash, bottom ash, blast furnace slag, red mud, and others. The geopolymer-based material has potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost as it utilizes industrial waste resources.
