A GCRF-EPSRC funded project
Our aim is to deliver new non-telluride thermoelectric (TE) materials, containing Earth-abundant elements, based on Indian mineral resources, able to generate electricity from waste heat. Approximately 100 million people in rural areas of India have no access to electricity. The areas which electrification has not reached are among the more remote, where off-grid electricity generation is essential. A TE device would provide sufficient electrical power to fulfil basic needs in lighting, communication and mobile device charging. Addition of a TE device to a chulha would therefore provide a cleaner cooking environment whilst simultaneously delivering a localised electricity supply delivering a major impact on the health and well-being of rural communities.
Objectives:
To design and produce efficient and cost-effective TE materials, to facilitate TE power generation using cookstoves (chulhas).
To align the development of n- and p-type semiconductors to the natural resources of India, by focusing on materials derived from copper sulphide ores.
To combine state-of-the-art computational and experimental methods to engineer ultralow thermal conductivity and excellent electronic transport properties into mineral-related phases.
To engage with end users, NGOs and the Indian government to formulate a design for a TE generator for incorporation in a chuhla to improve combustion, reduce indoor air pollution and generate useful electrical power. We will identify and address barriers to implementation, including cultural issues, to develop a pathway towards exploitation of materials advances.
