Innovative Solar-Powered Ice Maker Revolutionizes Cooling for Indonesian Island Fishery Communities

Frank Stegmueller, representing GIZ Indonesia, discussed a project focused on dynamic solar-powered off-grid cooling solutions for island fishery communities. The initiative addresses the critical issue of unreliable electricity access affecting 675 million people globally and its impact on cold chain logistics in remote areas like Indonesia's islands. Traditional diesel-based cooling methods are costly and environmentally detrimental. In response, GIZ developed a solar-powered ice maker capable of producing up to 1.2 tons of block ice daily using renewable energy with minimal greenhouse gas emissions. The system features innovative technology including variable frequency drives for compressors, thermal energy storage combining saltwater brine with battery backup, and segmented generators that efficiently manage power fluctuations from solar input. This solution not only enhances market access for small-scale Indonesian fishers but also contributes significantly to reducing CO2 emissions compared to conventional methods. Collaborations with international partners have expanded this project's reach beyond Indonesia into regions facing similar challenges while promoting sustainable practices within local ecosystems.

Off-grid solar systems are often the least expensive option for rural electrification. Solar home systems can power individual households, while mini-grids can supply entire villages. Each comes with its own advantages, disadvantages, and challenges. The aim of this session is to explore challenges as well as success stories. It takes well-functioning components such as battery systems, charge management and inverters to make projects successful. Proper system sizing, maintenance and repair management, as well as a robust financial concept are also necessary. If one of these elements is missing, the electrification will not be sustainable. This session will focus on the aspects mentioned above. The speakers will present successful and unsuccessful approaches and discuss what can be learned from them.
