Optimizing Energy Efficiency Under Uncertainty for Appropriate Technology Based Renewable Energy Processes in Developing Regions

The University of Kentucky Appropriate Technology and Sustainability (UKATS) Research Team has been engaged in designing a low-cost, sustainable processor for producing biodiesel and biochar in Sub-Saharan Africa. The team has constructed a multifunctional, non-automated (equipment) processor from simple, locally sourced materials based on appropriate technology fundamentals. The processor was tested and implemented during a research trip to Bangang Village, Cameroon, proving to be very productive and suitable for making desired biodiesel and biochar. To assess the total energy efficiency of the processor under sustainability applications, computational modeling has been conducted. The model was used to analyze the processor design under uncertainty due to non-standard constructional materials and parameters present in rural, developing regions. In return, its results describe the optimum energy efficiency reached by the processor when possible variations in its constructional design occurred. This research in Bangang village is performed in collaboration with the NGO, African Center for Renewable Energy and Sustainable Technology (ACREST).
