The Cold Chain Innovation Project solves the critical problem of cold chain failure in regions without electricity by combining ultra-efficient cooling, solar energy, advanced thermal insulation, and a clever carriage design, safeguarding internal supplies from extreme environments. The project was created to support Médecins Sans Frontières (MSF) in diagnosing epidemics in remote regions of Sudan, Niger, CAR, and DRC, where blood samples must be transported across extreme climates and poor infrastructure while staying between 2–8°C. The main challenge in this operations is the cold chain failure—when samples exceed this temperature limit and become unusable—mainly caused by the lack of electricity needed to refrigerate. With no existing solution addressing this major global issue, we set out to design an accessible and reliable system to be used by the courageous workers on the frontline of these critical missions.
