“…Repowering impact on global warming has also been investigated, and researchers found that the impact of removing the old and installing the new turbines (and other works) is “clearly offset by the benefits of increasing the generation of electrical power from renewable sources.” The visual effect was investigated based on a real case, and it was found that the repowering wind farm project achieved a 37% power increase with no additional visual effects . Last but not least, local acceptance is also usually higher for repowering projects compared with greenfield developments …”

This research investigates, analyses, and quantifies the technological effects of wind turbine repowering (ie, where old turbines are removed and new turbines are installed at the same or a very close location, including the enhanced performance in energy production). In these cases, it is assumed that both old and new turbines are subject to the same wind regime, other than because of technological elements, such as hub height, and thus it is possible to isolate the effects of new technology from the effect of changing local wind conditions. This research is based on the analysis of empirical data on repowering turbines in Denmark and Germany, and on historical production data available for the Danish component of the data set. Technological innovations are expected to enable new wind turbines to capture more energy at the repowering site, mostly through larger rotors and higher hub heights, and this is what this study has analysed. The results show that new turbines in repowering projects are twice as high, have three times the rotor diameter, nine times the swept area, six times the nominal power, and nine times as much electricity as the old turbines. However, the most significant improvement is probably the increase of capacity factor of 7.1% on a per-turbine basis, or 9.7% on a per-production basis.

“…Additionally, the sources of power generation of greater current use, especially the energy obtained from fossil fuels, generate detrimental environmental problems. Therefore, the global trend is focused on the de-carbonization and the use of renewable energy, such as solar and wind energy, small hydropower and hydrokinetic system, and ocean, geothermal and biomass power plant, among others, for the production of electricity [1][2][3]. Indeed, hydroelectric power remains one of the most cost-efficient sources of renewable energy production.…”

Recently, the utilization of low-head hydroelectric technologies has received a great attention for the expansion of distributed power systems into isolated regions that are difficult to be connected to the electrical grid, especially in developing countries. The use of gravitational vortex hydropower systems can be a renewable and suitable option to expand electricity access and promote development in these remote regions, which are concomitantly rich in hydric resources, due to this system can operate with low head without the need of a large reservoir and installation area. In this study, the performance of the inlet channel and basin of a gravitational water vortex turbine was investigated. Two inlet channels and two basin geometries were numerically analysed in Ansys Fluent software. The velocity and vortex height were calculated and compared for each setting. It was found that the inlet channel with conical basin tended to produce more symmetric vortex in comparisons with that generated by the cylindrical geometry. Additionally, the conical basin maximized the flow velocity on the water surface area.

“…Rising energy demands have led to a series of problems, such as increased fossil fuel consumption, depletion of non-renewable resources, environmental pollution problems, and political impacts [1][2][3]. Many scholars have studied clean energy, including wind [4,5], solar [6][7][8], geothermal [9,10], and tidal [11]. The use of batteries in electric vehicles (EVs) [12,13] to replace traditional fossil fuels can effectively reduce the global use of fossil fuels as automotive batteries provided good conversion and storage capabilities.…”

A battery thermal management system (BTMS) ensures that batteries operate efficiently within a suitable temperature range and maintains the temperature uniformity across the battery. A strict requirement of the BTMS is that increases in the battery discharge rate necessitate an increased battery heat dissipation. The advantages of heat pipes (HPs) include a high thermal conductivity, flexibility, and small size, which can be utilized in BTMSs. This paper experimentally examines a BTMS using HPs in combination with an aluminum plate to increase the uniformity in the surface temperature of the battery. The examined system with high discharge rates of 50, 75, and 100 A is used to determine its effects on the system temperature. The results are compared with those for HPs without fins and in ambient conditions. At a 100 A discharge current, the increase in battery temperature using the heat pipe with fins (HPWF) method is 4.8 °C lower than for natural convection, and the maximum temperature difference between the battery surfaces is 1.7 °C and 6.0 °C. The pulse circulation experiment was designed considering that the battery operates with a pulse discharge and temperature hysteresis. The depth of discharge is also considered, and the states-of-charge (SOC) values were 0.2, 0.5, and 0.8. The results of the two heat dissipation methods are compared, and the optimal heat dissipation structure is obtained by analyzing the experimental results. The results show that when the ambient temperature is 37 °C, differences in the SOC do not affect the battery temperature. In addition, the HPWF, HP, and natural convection methods reached stable temperatures of 40.8, 44.3, and the 48.1 °C, respectively the high temperature exceeded the battery operating temperature range.
