Powering a Space Environment Research Laboratory (SERL): Hybrid Renewable Energy System or Diesel System?

Purpose This study aims to analyze the effects of variations in annual real interest rates in the assessment of the techno-economic feasibility of a hybrid renewable energy system (HRES) for an off-grid community. Design/methodology/approach Hybrid Optimization of Multiple Energy Resources (HOMER) software is used to propose an HRES for Abadam community in northern Nigeria. The HRES was designed to meet the basic needs of the community over a 25-year project lifespan. Based on the available energy resources in the community, photovoltaic (PV), wind turbine, diesel generator and battery were suggested for integration to serve the load requirements. Findings When the annual real interest rates were taken as 10 and 8 per cent, the total amount of total energy fraction from PV, wind turbine and the diesel generator is 28, 57 and 15 per cent, respectively. At these interest rates, wind turbines contributed more energy across all months than other energy resources. The energy resource distribution for 0, 2,4 and 6 per cent annual real interest rates have a similar pattern, but PV contributed a majority of the energy. Practical implications This study has used annual real interest and inflation rates dynamic behavior to determine optimal HRES for remote communities. Hence, its analysis will equip decision-makers with the necessary information for accurate planning. Originality/value The results of this study can be used to plan and design HRES infrastructure for off-grid communities around the world.

“…The compression ignition mode via direct injection stands as a crucial technology for attaining efficient combustion. However, conventional fossil fuels impose substantial strains on environmental issues and energy security [1]. In addition, it is important to note that diesel combustion is known for its high levels of particulate matter (PM) emissions.…”

To elucidate the mechanism through which ethanol curtails soot formation in hydrogenated biodiesel, an experimental inquiry was undertaken by employing the high-frequency background light extinction technique within a constant volume combustion chamber system. The primary objective of this study was to scrutinize the impact of blending ethanol with highly reactive fuel on soot generation. Empirical evidence shows that ethanol, owing to its substantial oxygen content, has the potential to facilitate soot oxidation. Incorporating ethanol effectively diminishes soot formation in aspects of quantity, rate, and area. The initial time and location of soot formation increase as the ethanol blending ratio increases. The influence of latent heat of evaporation and Cetane Number on the initial time and location of soot formation varies with distinct environmental temperatures. At 750 K, the latent heat of evaporation exhibits a more pronounced influence in contrast to the Cetane Number. As the temperature rises, the Cetane Number gradually becomes more influential. At a temperature of 825 K and an oxygen content of 21%, the E30H60O10 blend shows an increase of 21.2% and 21.4% in the initial time and location of soot formation, respectively, compared to the E15H75O10 mix. Furthermore, there is a reduction of 75.8% in the total soot mass.

“…Application of the hybrid system has also been found useful in the agricultural sector, and the public lighting system . Although, several studies (Adaramola et al, 2014;Amutha and Rajini, 2016;Asrari et al, 2012;Babatunde et al, 2018;Li et al, 2013;Olatomiwa et al, 2015;Samson et al, 2019) have shown various utilization of hybrid renewable energy resources for both private and public applications. Still, there is no record of its application for gas stations which are predominantly operating on fossil fuels power generation, especially in Nigeria, due to the unreliable power supply peculiar to the developing countries.…”

It is crystal clear that appropriate technical sizing has a significant effect on the techno-economic analysis of an off-grid standalone energy system. As a result, this study presents the effect of incorporating the temperature coefficient in the optimal analysis of an off-grid hybrid system using a standard fuel (gas) station in Nigeria as a case study. Comparative analysis with and without the temperature coefficient was performed. The results showed that the inclusion of temperature coefficient leads to extra operation hours of the generator which will result in an increase in fuel consumption and annual operation cost of the diesel generator. Also, the initial cost of the PV/BAT/diesel is relatively higher than the diesel generator but, the generating emission of the hybrid system is lower when compared to the diesel-only which enhances the atmospheric condition of the society.
