The worldwide electricity supply network has recently experienced a huge rate of solar photovoltaic penetration. Grid-connected photovoltaic (PV) systems range from smaller custom built-in arrays to larger utility power plants. When the size and share of PV systems in the energy mix increases, the operational complexity and reliability of grid stability also increase. The growing concern about PV plants compared to traditional power plants is the dispersed existence of PV plants with millions of generators (PV panels) spread over kilometers, which increases the possibility of faults occurring and associated risk. As a result, a robust fault diagnosis and mitigation framework remain a key component of PV plants. Various fault monitoring and diagnostic systems are currently being used, defined by calculation of electrical parameters, extracted electrical parameters, artificial intelligence, and thermography. This article explores existing PV fault diagnostic systems in a detailed way and addresses their possible merits and demerits.

This work describes the synthesis and evaluation of nanocomposite membranes based on calcium phosphate (CP)/ionic liquids (ILs) for high-temperature proton exchange membrane (PEM) fuel cells. Several composite membranes were synthesized by varying the mass ratios of ILs with respect to the CP and all supported on porous polytetrafluoroethylene (PTFE). The membranes exhibit high proton conductivities. Two ionic liquids were investigated in this study, namely, 1-Hexyl-3- methylimidazolium tricyanomethanide, [HMIM][C4N3−], and 1-Ethyl-3-methylimidazolium methanesulfonate, [EMIM][CH3O3S−]. At room temperature, the CP/PTFE/[HMIM][C4N3−] composite membrane possessed a high proton conductivity of 0.1 S cm−1. When processed at 200 °C, and fully anhydrous conditions, the membrane showed a conductivity of 3.14 × 10−3 S cm−1. Membranes based on CP/PTFE/[EMIM][CH3O3S−] on the other hand, had a maximum proton conductivity of 2.06 × 10−3 S cm−1 at room temperature. The proton conductivities reported in this work appear promising for the application in high-temperature PEMFCs operated above the boiling point of water.

Dust accumulation on the photovoltaic (PV) surface decreases the solar radiation penetration to the PV cells and, eventually, the power production from the PV system. To prevent dust-based power losses, PV systems require frequent cleaning, the frequency of which depends on the geographical location, PV integration scheme, and scale of the PV power plant. This study aims to measure the drop-in radiation intensity, as well as power output, due to dust and to determine the optimal time interval for PV cleaning in the United Arab Emirates (UAE) climate. In this research, a dusting study experiment was carried out at the Renewable Energy Laboratory, Falaj Hazza Campus, UAE University, Al Ain, UAE, for 3.5 months, from 22 April 2018 to 7 August 2018. To measure the pure radiation losses caused by the dust, four transparent glasses were used to mimic the top glass cover of the PV modules. The dusting induced power losses were measured for four selected PV cleaning frequencies (10 days, 20 days, 1 month, and 3 months). This study revealed that up to 13% of power losses occurred in PV panels that remained dusty for 3 months, compared to panels that were cleaned daily. PV cleaning after 15 days brought the losses down to 4%, which was found the most feasible time for PV cleaning in this study, considering a reasonable balance between the cleaning cost and energy wasted due to soiling.

Produced water is the largest waste stream generated in oil and gas industries. It is a mixture of different organic and inorganic compounds. Global produced water production is estimated at around 280 million barrels per day compared with around 97 million barrels per day of oil. As a result, water to oil ratio is around 3:1 that is to say; water cut is 70%. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging produced water on the environment has lately become a significant issue of concern. In certain fields like Asab oil field Abu Dhabi UAE, the produced water is re-injected in the field through injection wells. However, it is found that the concentration of salt in injected formation water in Asab field is 150,000-262,000 ppm and this high saline water is injected in the reservoir. Where it may cause severe formation damage: pore plugging, water injectivity and oil productivity problems. Our objective is to develop a cost effective technique to reduce the salinity of this produced water to control formation damage. We used a couple of chemicals/reagents to reduce the salinity of injected water in Asab field, to increase oil recovery and minimize formation damage such physico-chemical and/or pore blockage. This research examines the sources, characteristics, and extent of different chemicals specially fatty acids and different other techniques that can be used to reduce the salinity of water because no single technology can meet suitable effluent characteristics, thus two or more treatment systems might be used in series operation. However, we were successful to reduce the salinity of brine to approximately 64-74%, where it can be re-injected into the reservoir with minimum formation damage and maximum injectivity.
