Thermoelectric generator being developed for Ghana, Nigeria

Researchers at the University of Derby are developing a thermoelectric generator for use in rural Ghana and Nigeria.

They said it could reduce the number of premature deaths caused by indoor pollution. The three-person research team has been awarded $126,000 for an 18-month project as part of Innovate UK's Energy Catalyst programme.

Zaharaddeen Hussaini, Dr Hirbod Varasteh, and Dr Mounia Karim, said their unique hybrid energy generator and storage system could help save lives.

They have completed a feasibility study for the device that combines the ability to use concentrated heat from the sun for cooking with a thermoelectric generator.

The generator will also provide electricity that can power small domestic appliances including mobile phone chargers and radios.

"Waste heat from the cooking process is captured and transformed into electricity.

"The project aims to provide clean cooking and off-grid renewable energy systems to rural communities in Nigeria and Ghana and provide a way to deliver secure, low-emission and affordable energy."

Hussaini, a Concentrated Solar Power (CSP) researcher at the university, pointed out the potential life-saving impact of the system. It is specifically designed for use in rural Nigeria and Ghana.

"The lack of access to grid energy in these regions forces residents to rely on traditional open-fire cooking methods." This leads to indoor pollution that contributes to over 500,000 premature deaths each year in sub-Saharan Africa, he said.

"By providing a sustainable alternative, this innovative system has the potential to not only save lives but also bring electricity to communities that have long been disconnected from the grid."

The system uses a concentrating solar collector to generate heat for cooking, while a thermoelectric generator captures the waste heat and converts it into electricity.

This solution improves access to clean energy. Its integrated storage tank allows for the storage of energy generated by the sun. This makes power available for use during periods of low or no sunlight. This ensures a reliable and sustainable source of energy for households.

The team is refining the system's design in the UK. They will then travel to the two African countries where they will assemble and test it. They will also provide training on the advantages of clean cooking.
