Scientists in Ghana have developed a solar PV-powered steam cooker with sand-based thermal energy storage, achieving a thermal efficiency of 38.9% and a payback period of 4.5 years. The system utilizes sand for its thermal stability and low cost, with the potential to reduce emissions and support Ghana's climate targets. Testing showed the system could cook large quantities of food efficiently and reliably, with a lifecycle cost analysis indicating significant cost savings compared to traditional biomass stoves. The integration of steam cooking with sand-based TES in solar PV-electric systems is a novel approach with promising results for sustainable cooking solutions. The Nkrumah University of Science and Technology, Technology Consultancy Centre, International Centre for Innovation, Manufacturing, Technology Transfer, and Entrepreneurship, and Cape Coast Technical University are likely involved in technology and innovation related to climate solutions.
