Youth-led solutions for vaccine and agricultural cold chain challenges in Sub-Saharan Africa

This case study describes the development of the Bi-Solar Tech Fridge by Triomphant Tchulang to address heat-related health and agricultural storage challenges in Northern Cameroon using solar energy.

• Triomphant Tchulang developed the Bi-Solar Tech Fridge over a two-year period to address challenges in Northern Cameroon where high temperatures and heatwaves impacted community health and the storage of agricultural produce.
• The initial prototype for the absorption solar refrigerator faced three primary technical limitations: it only produced energy for parts of the day, the internal storage space was small relative to the unit's size, and it was unable to reach freezing temperatures.
