Best insight from top research papers
Net Present Cost (NPC) is a key factor in assessing the feasibility of hybrid energy systems for unconnected villages in Nigeria. Several papers have focused on the techno-economic viability of different configurations of hybrid energy systems using renewable energy sources such as solar, wind, hydro, and diesel generators. The simulation results show that incorporating solar PV and battery storage into the existing system can significantly reduce the NPC and decrease the reliance on diesel fuel . The optimal configuration of a hybrid renewable energy system (HRES) with the lowest NPC includes a combination of solar PV, wind, diesel generator, and battery storage . These hybrid systems not only provide a sustainable power supply but also contribute to reducing carbon dioxide emissions and improving the environmental friendliness of the energy generation .

What are the statistics of energy poverty in Nigeria?5 answersEnergy poverty in Nigeria is a significant issue, with a majority of households being classified as energy poor. The Multidimensional Energy Poverty Index (MEPI) was used to estimate the national average MEPI, which was found to be 0.38. This suggests that a large proportion of households in Nigeria are energy poor. Energy poverty is more prevalent in rural areas compared to urban areas. Factors that contribute to energy poverty include male-headed households, age, rural sector, and northeast residents, while household income and credit access act as inhibiting factors. The incidence of energy poverty in Nigeria is high, affecting over 75% of the population. In the south-south geopolitical zone of Nigeria, 83.2% of inhabitants are energy poor. These statistics highlight the urgent need for interventions to address energy poverty in Nigeria and promote sustainable development.
What are the statistics of energy poverty in Nigeria?4 answersOver 90% of respondents in rural Nigeria live below the multidimensional energy poverty (MEP) line, with the North East (NE) and South West (SW) having the highest and lowest rates, respectively. The national average MEP is 0.38, indicating that the majority of households in Nigeria are energy poor. Energy poverty is higher in rural areas compared to urban areas. The incidence of extreme energy poverty in Nigeria affects over a fifth of the population, with higher rates in rural and Northern Nigeria. Only 40% of Nigeria's population has access to electricity, and power outages are frequent and prolonged. Kerosene explosions, fuel ignition, candles, electricity, and gas explosions are common causes of burns incidents, resulting in preventable morbidity and mortality. The study recommends implementing policies for energy access and equitable distribution to help households meet their energy needs safely.
What are the potential benefits and challenges of hybrid renewable energy systems?5 answersHybrid renewable energy systems (HRESs) offer several potential benefits, including providing environmentally sustainable, secure, and affordable energy for rural electrification. These systems optimize the generation of electricity by minimizing the levelized cost of electricity (LCOE) and carbon emissions. HRESs can also contribute to energy sustainability, reliability, and environmental friendliness. By combining multiple energy sources, such as solar and wind, HRESs can offset the intermittent and unpredictable nature of these resources, resulting in a more reliable and economical system. Additionally, HRESs have the potential to create flexible energy production and consumption options, making the overall energy system more adaptable. However, there are also challenges associated with HRESs, such as the complexity of integrating different energy carriers and grids, the need for appropriate technologies and infrastructure financing, and the requirement for integrated system planning and supportive market frameworks.
How does the adoption of hybrid renewable energy systems affect electricity market pricing and demand?5 answersThe adoption of hybrid renewable energy systems has several impacts on electricity market pricing and demand. These systems can generate significant energy excess to demand, which needs to be disposed of. However, when properly optimized, hybrid systems can provide reliable electricity and fresh water to communities, while also maximizing job creation and minimizing costs. Additionally, the pricing strategy for system operators can stimulate the development of the renewable energy industry by properly setting purchase prices. Higher renewables penetration can reduce the incentive for conventional electricity generators to sell forward production, undermining the role of forward contracting in mitigating market power. The increasing share of renewable electricity in the energy mix has a positive and statistically significant impact on retail electricity prices. Overall, the adoption of hybrid renewable energy systems can have both positive and negative effects on electricity market pricing and demand, depending on factors such as optimization, pricing strategies, and renewables penetration.
How to design a hybrid renewable energy system that is cost-effective and reliable?3 answersA cost-effective and reliable design for a hybrid renewable energy system can be achieved through optimal sizing and performance evaluation. The use of machine learning and hybrid metaheuristics can predict weather patterns and optimize the system size based on forecasted data over the lifespan of the system. The hybrid system should utilize a mix of renewable energy sources such as solar photovoltaic (PV), wind, and energy storage systems like batteries. The sizing of the components should be based on load profiles, potential energy sources, and geographical location. The design should consider the technical feasibility, capital cost, and energy sustainability of the system. Optimization algorithms and meta-heuristic approaches can be used to determine the optimal sizing of the hybrid system. A comprehensive review of optimization techniques can provide insights into the progress made in designing cost-effective and reliable hybrid energy systems.
Is hybrid-electric propulsion system is more expensive then electric?5 answersHybrid-electric propulsion systems can be more expensive than electric propulsion systems, depending on various factors such as technology, performance, and optimization.The cost of hybrid systems can be influenced by the complexity of powertrain architectures and the need for additional components such as internal combustion engines and control systems.However, advancements in adaptive motors and generators for electric vehicles have made them cheaper, smaller, lighter, and more efficient, potentially reducing the cost difference between hybrid and electric systems.Additionally, the cost of electric automobile power systems has been a challenge due to high costs, low reliability, and availability of power electronic components.It is important to note that the cost of hybrid-electric propulsion systems can vary depending on the scale of the application, with smaller and mid-scale sectors potentially benefiting more from fuel savings and efficiency improvements.Further research and development efforts are needed to optimize hybrid-electric propulsion systems and reduce their overall cost.
