Transforming Spent EV Batteries into Clean Energy: Insights for Investors and Entrepreneurs in Oman
MUSCAT, APRIL 15 — As the global movement towards clean energy accelerates, significant challenges are surfacing regarding the management of spent electric vehicle (EV) batteries. However, this situation also presents promising opportunities for their use in sustainable energy storage solutions. A recent study conducted in Oman has showcased the significant technical and economic viability of reusing these batteries in renewable energy systems.
The research team, comprising Sarah al Zajali, Haya al Ghabshi, Zalkha al Akhzami, and Dr. Mohammed al Alawi from the College of Engineering and Technology at the University of Technology and Applied Sciences in Muscat, undertook this vital study.
Sarah al Zajali stated, “The findings of our research aimed to support the integration of renewable energy, enhance energy efficiency, and promote sustainable energy solutions in the region. We demonstrated that incorporating reused batteries with photovoltaic solar energy systems can deliver reliable, cost-effective, and environmentally sustainable energy.”
The study revealed that systems integrating reused batteries with photovoltaic solar setups not only provided dependable and economical energy but also offered considerable environmental benefits. Furthermore, the efficiency of charging and discharging for these batteries exceeds 91%, underscoring their technical reliability.
Three distinct sites in Oman were included in the study, representing varied environments: Al Dhafrat (residential), Al Duqm (industrial), and the Shaleem and Al Hallaniyat Islands (remote coastal areas). Four scenarios over a 25-year period were analyzed, focusing on the application of both new and used batteries within solar and hybrid (solar-wind) systems. The results indicated that systems utilizing batteries with a second life achieved substantial economic savings compared to those using new batteries. Specifically, the hybrid (solar-wind-used batteries) system registered the lowest adjusted energy cost in Al Duqm at 8.29 cents/kWh and in the Shaleem and Al Hallaniyat Islands at 6.94 cents/kWh. Meanwhile, in Al Dhafrat, the solar system that incorporated used batteries showed competitive performance with a cost of 16.14 cents/kWh, reflecting a positive net present value and confirming its investment feasibility.
The study underscores that reusing electric vehicle batteries provides a practical avenue for supporting the circular economy, especially since these batteries retain 70-80% of their original capacity following their use in vehicles. This aligns with Oman’s ambitions to establish itself as a regional hub for clean energy, bolstered by investments in the battery sector and related materials projects, ultimately aiming to optimize solar energy use and minimize waste.
These initiatives are in harmony with the goals of Oman Vision 2040, which emphasizes economic diversification, resource optimization, and a transition to a circular economy model centered on reuse and recycling.
