Frank Stegmueller, from GIZ Indonesia, presented a project on solar-powered off-grid cooling solutions for island fishery communities. This initiative is part of the Outstanding Project Award as a finalist in The Smarter E-Award 2025 and represents years of technical cooperation to address energy access issues faced by remote communities worldwide. These areas suffer significant post-harvest losses due to lack of reliable cold chains, relying instead on costly diesel power systems with high carbon emissions. In response, the project developed a solar-powered ice maker capable of producing up to 1.2 tons of block ice daily using renewable energies and natural refrigerants—virtually emission-free. The system operates dynamically through three main components: variable frequency drive compressors powered by photovoltaic panels; an energy storage solution combining saltwater brine tanks with LFP batteries; and segmented ice generators that efficiently manage production based on real-time conditions. By re-engineering conventional technology for sustainable use in isolated regions like Indonesia's islands, this innovation not only reduces CO2 emissions but also supports local economies while mitigating ocean plastic waste—a testament to international collaboration between German-Indonesian partners aiming at scalable global impact against climate change challenges within fisheries' supply chains globally reliant upon fossil fuels traditionally contributing significantly towards greenhouse gas outputs annually increasing demand cleaner smarter integrated applications such projects exemplify progress achievable collective efforts tackling pressing environmental concerns today tomorrow alike!
