Techno-economic assessment of a hybrid renewable energy storage system for rural community towards achieving sustainable development goals

Urbanization and population growth are driving carbon emissions, along with the imperative for renewable energy transition, necessitating researching the impact of hybrid renewable energy storage systems towards achieving sustainable development goals. The article presents a techno-economic assessment of a stand-alone hybrid system in a grid-deficient rural community in a developing country, Bangladesh. The optimal system sizing includes an 8.67 kW of photovoltaic, 7 kWh lithium-ion battery, 6 kW of electrolyzer, 1.8 kW fuel cell, 5 kg of hydrogen tank and 1.67 kW converter, which can achieve a net present cost of $25,099 and levelized cost of energy of $0.34$/kWh. Results show hybrid system supports sustainable development goals by offering clean energy, emphasizing the need for government support, investment, and scaling in rural developing areas. •Urbanization and population growth are driving carbon emissions.•Renewable technologies rise against the detrimental effects of fossil fuel burning.•Techno-economic assessment of renewables are needful to achieve sustainability.•Solutions need to be optimal for levelized cost of energy and emission reduction.•Renewable energy systems contribute to achieve sustainable development goals.
