This aim of this UK-Nigeria-Ghana mid-stage collaborative project is to optimise the concentrated-solar-power (CSP) and thermoelectric generator (TEG) hybrid energy system we developed in previous project, testing and demonstrating them in relevant user environment. The system has clear benefits of providing both clean energy for cooking and off-grid electricity, addressing the energy access issue in the targeted countries. The project will allow the UK consortium (Thermoelectric Conversion Systems, Cranfield University and University of Derby) to collaborate with a Nigerian company (IBEDA) and a Ghanian company (Conlons Kitchen) to optimise the design of the energy system, build demonstrators locally in Nigeria, field test its performance in rural communities of Nigeria and Ghana, conduct market research, and develop relevant GEIS and business models. The system will have an additional international market in other sub-Saharan and South Asian countries. This project will enable the consortium to progress into further TRL development and commercialisation post-project. Successful outcomes will bring competitive energy products to a significant and growing market.
