In the heart of North Togo, a groundbreaking hybrid renewable energy system (HRES) is making waves in the energy sector, promising a future where sustainability meets economic viability. The research, led by Maklewa Agoundedemba from Kenyatta University, has been presented at the SolarPACES Conference Proceedings, which translates to the Solar Power and Chemical Energy Systems Conference Proceedings.
Agoundedemba’s study introduces a novel configuration that combines concentrated solar power (CSP) with thermal energy storage (TES), photovoltaic (PV) modules, and battery energy storage systems (BESS). This hybrid approach aims to enhance energy production efficiency, reduce costs, and minimize environmental impact.
The research utilized parametric optimization through the System Advisor Model (SAM) to determine the optimum levelized cost of energy (LCOE) and net present value (NPV). The results are promising, with an LCOE of $0.14 per kWh, indicating a competitive cost of energy production. The internal rate of return (IRR) stands at an impressive 14.87%, showcasing strong investment returns. Moreover, the high NPV of $9,307,001 suggests significant interest in the proposed HRES.
“Our findings demonstrate that this hybrid system is not only financially viable but also makes a substantial contribution to sustainability,” Agoundedemba stated. The project is expected to reduce CO2 emissions by 25,815.7513 tons, highlighting its potential to combat climate change and reduce carbon footprints.
The integration of heliostats—mirrors that concentrate sunlight onto a central receiver—with thermal energy storage allows for energy production even when the sun isn’t shining. This feature, combined with the flexibility of PV modules and the reliability of BESS, makes the system a robust solution for regions with variable weather conditions.
The commercial implications of this research are substantial. Energy providers can leverage this technology to offer more reliable and cost-effective renewable energy solutions. The financial viability and environmental benefits make it an attractive option for investors and policymakers alike.
As the world grapples with the urgent need for sustainable energy solutions, Agoundedemba’s research offers a beacon of hope. “This study is a step towards a future where renewable energy is not just a choice but a standard,” Agoundedemba added.
The findings from this research could shape future developments in the renewable energy sector, encouraging more hybrid systems that combine multiple energy sources to maximize efficiency and reliability. As the energy sector continues to evolve, such innovations will be crucial in meeting global energy demands while minimizing environmental impact.
