Solar thermal systems provide process heat for industrial processes, possessing the potential to reduce the carbon footprint of textile, food, beverage, paper and chemical industries. The project aims to increase the use of these systems in Brazil, India, Mexico and South Africa; countries in which the technology is economically viable but information failures, lack of experience and other barriers impede its commercialization. The project partners with local chambers and associations, following a multiplier approach to support policy makers, project developers as well as small and medium-sized enterprises (SMEs) in their understanding of the techno-commercial potential of this technology and its subsequent adoption. The development of business and financing models via energy service companies (ESCOs) and financial institutions as well as reference systems will further improve the technology‘s viability. Policy makers will be enabled to enhance the framework for its effective adoption.
