“…Currently, energy fuel resources are mainly based on non-renewable fuels, and they face gradual depletion [4]. However, renewable sources that are derived directly or indirectly from the sun or from other natural mechanisms can be supplemented within a short time scale [5].…”

In this study, various national strategies and programs are described by planning instruments. The TIEB (Thailand Integrated Energy Blueprint), which includes six programs (AEDP, PDP, EEDP, ODP, GDP, REDP), aims to regulate renewable energy and improve the use of biofuel. In addition, the potential of second-generation biofuels is estimated with different residue extractions of second-generation biomasses: 20% (scenario 1), 44% (scenario 2), and 66% (scenario 3). Based on the production potentials that were estimated, CO2 will decrease 1.3–3.5 megatons in the gasoline sector, and 1.4–3.8 megatons in the diesel sector under scenario 1. In scenario 2, we estimated decreases of 2.8–7.7 mega tons and 3.2–8.4 mega tons of CO2 for the gasoline and diesel sectors, respectively. Finally, scenario 3 is expected to reduce the CO2 concentration by 4.2–11.6 megatons in the gasoline sector, and by 4.7–12.6 megatons in the diesel sector. We also estimate the economic potential of a second-generation biofuel with the view of emissions trading. For bioethanol and biodiesel, respectively, 27–74 million USD and 30–81 million USD could be realized in scenario 1, 60–163 million USD and 67–178 million USD in scenario 2, and 90–244 million USD and 100–267 million USD in scenario 3. We conclude that the future potential of second-generation biofuels in Thailand is optimistic, and that they can provide both environmental and economic benefits to the country.

“…Las crecientes demandas energéticas y procesos antropogénicos causantes del cambio climático hacen necesario el recurrir a fuentes alternativas de energía limpia, renovable y con potencial de expansión con menor impacto [1]. Una condición ideal es que puedan, además, desplegarse en edificaciones y contextos urbanos [2,3].…”

Esta investigación calibra y valida un modelo de sistemas fotovoltaicos monocristalinos en la herramienta computacional System Advisor Model (SAM) para simulación de generación eléctrica, considerando las características meteorológicas en Cuenca (Ecuador), ciudad en altura próxima a la línea ecuatorial. Se obtiene el rendimiento eléctrico al desplegarse paneles fotovoltaicos de características específicas, con inclinaciones que responden a techumbres típicas locales y distintas orientaciones. Se calcula la eficiencia con mediciones in situ durante un período de 18 días, para que, con datos meteorológicos se calibre un archivo climático para el año 2016. Se estiman rendimientos anuales acorde a inclinación y orientación, y a características técnicas de los fotovoltaicos. Se detectan pérdidas por acumulación de suciedad e incremento de temperatura de las placas. Se valida el modelo mediante una regresión lineal, al comparar los valores simulados con los datos obtenidos de mediciones in situ de un panel en posición horizontal. Los resultados indican una pérdida promedio de eficiencia de 2,77 % por condiciones de suciedad y de hasta el 30 % por incremento de temperatura. La validación del modelo mostró un coeficiente de determinación R2 = 0,996 y un RMSE normalizado de 8,16 %. Se concluye además que, por la latitud particular del sitio en estudio, a diferencia de la mayor parte del planeta, la disposición de paneles fotovoltaicos en cualquier orientación considerando pendientes bajas, no reduce significativamente el rendimiento en la generación de energía eléctrica anual.

“…The energy gathered from the sun can be used through three hightech conversion processes that include thermal, chemical and electrical [34]. Solar energy can be converted into mechanical energy like wind energy, hydro energy, and steam energy is converted into mechanical energy [20,41]. Solar energy is collected through a solar collector that is a special kind of heat exchanger [3,57].…”

Performance evaluation of solar flat plate collector using different working fluids through computational fluid dynamics

The aim of this study involves establishing a three-dimensional computational fluid dynamic (3D-CFD) model of solar flat plate collector (SFPC) in order to investigate the effect of operating and geometric parameters on thermal efficiency. In this research work, commercial CFD code ANSYS FLUENT ® 14.0 version was used for the development of a model of solar plate collector. The single circular tube geometry was created using ANSYS DesignModeler ® 14.0. The general continuity equation along with Navied-Stokes equations was solved for tracking motion of the working fluid. The general k-ε turbulence modeling approach was used for solving the turbulence in the flow. Solar ray tracing was activated for calculating solar load in the model. The latitude and longitude of the Hyderabad region were inserted in the solar raytracing model for calculating solar intensity as per local conditions. Two fluids i.e., water and air were circulated with different flow rates in the developed model of SFPC. It was observed that water gave higher efficiency due to high density and thermal conductivity. The simulation results gathered revealed that the temperature of water and air was raised by almost 79 °C and 73 °C respectively.
