Techno-economic feasibility assessment and performance analysis of standalone solar photo voltaic-biomass hybrid system with optimized storage: a case study—Grand Bassa, Liberia

Abstract

Introduction: Liberia has a significant obstacle in terms of restricted power accessibility, as only 26.7% of its populace have access to electrical energy. To tackle this issue, there is a collaborative effort between the government and private sector to undertake energy projects aimed at enhancing the power supply of the grid. The purpose of this study is to evaluate the techno-economic feasibility and analyze the performance of a standalone biomass/solar photovoltaic (PV) hybrid energy system for a rural Liberian community that mostly relies on traditional biomass.Methods: HOMER pro program was used to configure the system, model the community’s load over a year, and generate the resource data of the location.Results and Discussion: Four different configurations were obtained and analyzed both technically and economically to determine the most feasible configuration. This study has shown that a hybrid configuration incorporating Biomass Gasifier, Solar PV, and Battery storage is more feasible with annual output power of 77104 kWh/yr, LCOE ($/kwh) of 0.29 and NPC ($) of 0.3979 million. If implemented with external funding, it will enhance the education, economic and socio-economic status of rural settlements. The results will serve as a valuable resource for informing choices on the implementation of the hybrid energy solution and guaranteeing its sustained efficacy within the community.

Technical, economic, and environmental feasibility assessment of solar-battery-generator hybrid energy systems: a case study in Nigeria

“…Using multiple energy sources in hybrid energy systems enhances power supply consistency and reliability, mitigating weather changes and maintaining a consistent electrical supply even when a single energy source is not operating at maximum capacity (Adaramola et al, 2014;Come et al, 2021). Numerous studies have shown that hybrid power systems are more reliable and cost-effective than single-source energy systems based on viability, dependability, and economic assessments (Nfah and Ngundam, 2008;Ajao et al, 2011;Adaramola et al, 2012a;Tijani et al, 2014;Oladigbolu et al, 2019;Yimen et al, 2020;Al-Rawashdeh et al, 2023a;White et al, 2024). Moreover, integrating diverse energy sources might lead to long-term cost reductions compared to depending only on a single form of renewable energy system (Oladigbolu et al, 2019;Yimen et al, 2020).…”
