Abstract null null This research evaluates the potential of a native marine isolate, Chlorella S4, for bioethanol production using the Thermo-Tolerant (TT) strain of Saccharomyces cerevisiae. Initially, an acid-thermal pretreatment with different concentrations of microalgal biomass (2, 4, and 6% (w/v)) and H2SO4 (1.5, 3, and 4.5% (v/v)) was investigated to improve the release of glucose (an important substrate of fermentation). The glucose concentration was enhanced 3.7 fold from 0.048 to 0.179...

Abstract null null In this study, we investigated the impact of incorporating graphene with Ga-doped ZnO (GZO) when employing them as a TCO layer on Si-based solar cell. GZO thin films with various thicknesses (50–450 nm) were fabricated by the sputtering method using a single target. The aim here was to determine the GZO film with the optimum thickness to incorporate it with single layer graphene as TCO. This thickness was found to be 350 nm as that was the best crystalline quality found in the...

Abstract null null After developing the methodology, we applied it to the case of the Netherlands highways. We show that the average irradiation on the Dutch highway network is around 880 kWh/m2/y, 35% less than the potential of an optimally tilted conventional PV system in the south of the Netherlands. Covering the entire 1600 km of the Dutch highways network with solar road modules of poly c-Si, mono c-Si and CIGS would respectively generate 5.2 TWh/y, 6.6 TWh/y, and 3.4 TWh/y of DC electricit...

Abstract null null In this study, the techno-economic performance of supercritical carbon dioxide (sCO2) power cycles in concentrating solar power plants based on particle technology is assessed. A simplified levelized cost of electricity calculation was used to investigate the effect of cycle parameters, compare cycle layouts and allow for comparing optimized sCO2 power blocks with steam technology. Results showed that simple cycle layouts with fewer components and lower cycle parameters lead t...

Abstract null null This study employs the econometrics test of endogenous structural breaks to separately investigate the changes in trends of the share of hydropower and non-hydro renewable power in electricity production for China using two separate sub-panels of data spanning from 1971-2015 and 1990–2015. To identify structural changes in each renewable power generation series, we apply the Bai and Perron procedure for determining structural breaks to estimate shifting-mean autoregressions an...

Abstract null null The experimental and computational analyses of a 500 m deep coaxial borehole heat exchanger system for geothermal power generation are studied in this paper. The experiments are carried out on a high temperature resourced well with an average thermal gradient of 0.38 °C/m. The experiment lasts 456 h, and the findings are described in terms of fluid inlet and outlet temperatures, subsurface temperature distribution profiles over time, and flowrate. The in-situ ground temperatur...
Abstract null null Off-grid photovoltaic energy systems (PESs) are increasingly being used for the electrification of remote areas in Brazil, owing to the need for carbon emission avoidance, potential approval of solar resources, and cost-effective expansion limits for conventional distribution systems. However, the complex environment, social, economic, and geographical aspects turn the operation and maintenance (O&M) of PES into a logistic and technical challenge in remote areas. Therefore, th...

Abstract null null Vehicles parked under blazing sun increases the cabin temperature to a broiling point as greenhouse effect comes into play. Similar is found in winter season when vehicle is parked in open, cabin temperature falls drastically. This extreme rise and fall in the vehicle cabin temperature, results in more fossil fuel consumption to power air-conditioner for high loads, which eventually leads to increase in generation of harmful gases. Additionally, the drastic condition inside ve...

Abstract null null A novel compact model is developed to predict the PV temperature Tpv, coefficient f which relates Tpv with the in-plane solar irradiance IT, and power output Pm. The Tpv, IT, ambient temperature Ta, and wind velocity vw on a sun-tracking pc-Si PV and c-Si BIPV were monitored. f depends explicitly on vw, PV efficiency, heat losses coefficient, and implicitly on Tpv, IT, Ta, loosely on the module inclination at low vw, while this effect weakens at high vw. Tpv prediction is prov...

Abstract null null Waste-to-energy (WTE) technologies convert municipal solid, and biomass wastes into affordable renewable heat and power energy. However, there are large uncertainties associated with using waste feed as a renewable energy source. This paper proposes a WTE management tool that provides forecasting and real-time optimization of power generated with the consideration of anomaly. The WTE management framework was designed based on a biological neural network, the Hierarchical Tempo...
