In a developing world where the demand for energy increases every day, the use of hybrid systems is a viable and important solution. The rivers present a significant potential for the electrical generation from the hydrokinetic use of the river currents, as well as the use of the solar radiation by means of the generation of photovoltaic solar energy for the electrical supply in rural areas. This...
Electric vehicles are the most promising sustainable transport technology for solving problems linked to the internal combustion engine vehicles. Wireless charging reduce the main problems associated with electric vehicles, driving range, charging time and size and cost of the battery. Inductive power transfer is the most promising technology for dynamic wireless charging of electric vehicles, which...
Direct normal solar irradiance (DNI) series of high-frequency time resolution permit an accurate modeling and analysis of transient processes in concentrating solar thermal power (CSTP) technologies. Numerical weather prediction (NWP) models provide an overall understanding of solar forecasting, but they are unlikely to cover a local statistical representativeness of the DNI high frequency dynamics...
In this study, CO2 gasification process of a marine biomass (Nannochloropsis gaditana microalgae char) has been evaluated. The experiments have been carried out according to a central composite design (CCD), by using a high-pressure thermogravimetric analyzer (HP-TGA). The effect of temperature, total pressure and gasifying agent volume concentration on the CO2 gasification process was studied. Within...
Although electric vehicles (EVs) are experiencing a considerable upsurge, the technology associated with them is still under development. This study focused on the control and operation of a medium-voltage direct-current (MVDC) microgrid with an innovative decentralized control system, which was used as a fast charging station (FCS) for EVs. The FCS was composed of a photovoltaic (PV) system, a Li-ion...
Combustion characteristics of two woody crops (BP (black spruce and Pinus banksiana mixtures) and W (willow)) and three herbaceous non-perennial energy crops (CR (common reed), RP (reed phalaris) and S (switchgrass)) were studied by means of TGA (thermogravimetric analysis) and DSC (differential scanning calorimetry) coupled with MS (mass spectrometry). The combustion process of these biomasses is...
Pyrolysis characteristics of three species of microalgae (SC (Scenedesmus almeriensis), NG (Nannochloropsis gaditana) and CV (Chlorella vulgaris)) have been studied by TGA–MS (thermogravimetric analysis coupled with mass spectrometry). The thermal behavior of microalgae samples could be described according to their biochemical composition and, in different extension, to their content in inorganic...
Pyrolysis and gasification processes of three types of lignocellulosic biomass (Eucalyptus wood, fir wood and pine bark) and biomass main components (cellulose, xylan and lignin) were studied by thermogravimetric-mass spectrometric analysis. Biomass samples were pyrolyzed between 30 °C and 1000 °C obtaining a solid fuel (char) that was later gasified using steam as the reacting agent (5% vol.). The...
