Description

The Sustainable Energy Solutions Catalogue is designed for users both within and outside the scope of SESA. Inside SESA, it offers an introduction to solutions that can be utilized in collaboration with various stakeholders, including local governments and civil society. Additionally, the catalogue updates users within the project about activities at SESA validation and replication sites. Externally, it informs users about the various solutions tested during SESA project implementation and serves as a comprehensive source of introductory information on sustainable energy solutions for a diverse set of stakeholders.  

During the next decades, the strong uptake of electric vehicles (EVs) will result in the availability of batteries that can no longer be used in EVs but are still useful for stationary applications. Extending the lifetime of EV batteries has significant economic and environmental benefits and is an important piece of Africa’s energy transition. This factsheet reviews the potential for use of Lithium-ion (Li-ion) second-life batteries (SLBs) in the context of sustainable energy solutions currently emerging in the African context. It sums up key technologies, business models, and impacts, and presents examples of SLB use across the continent.  

Dealing with the End-of-Life Problem of Electric Vehicle Batteries – Insights and Recommendations for Kenya 

A comprehensive e-mobility strategy requires the management of batteries after the end of their use in EVs. Smart reuse and recycling systems need to be put in place as they can help to prolong the life cycle of such used batteries and provide significant business opportunities. This short paper gives an overview of the topic and ties it to the Kenyan context.

Battery Second-Use Repurposing Cost Calculator 

The National Renewable Energy Laboratory of the U.S. Department of Energy developed a calculator for the determination of repurposing costs for the second use of EV batteries. The tool accounts for factors such as module ownership, transportation, handling and testing time as well as costs, staff and required revenues.

Repurposing of Lithium-Ion Batteries – Technology & Market Insights
This study identifies the key drivers and barriers for adoption of Second Life Batteries (SLB). The challenges include handling the diversity of electric vehicle (EV) battery packs in the market, costly battery transportation, development of grading and disassembly processes, difficulty in accessing historical data of used batteries, and the lack of unified standards for used battery repurposing. The study examines 33 case studies of SLB implementation in various applications, such as reuse by EV OEMs, energy storage systems (ESS) for grid stabilization, back-up power systems, smart grids, home ESS, EVs, and portable power.
