This prospective study aimed to mitigate the emission of hydrocarbon gases and economic or energy losses. It consisted in designing a storage system for this volatile fluid, based on local materials, capable of ensuring thermal comfort, under natural conditions of terrestrial heating. In view of their respective theoretical availability, accessibility and thermal conductivity, cotton, sand and shea cake have been identified as potential insulators. For this purpose, identical samples of the fuel were buried, each with a specific material. They were respectively subjected to a fraction of solar energy, transmitted according to the thermal properties of the material crossed. The monitoring of the evolution of the different evaporation rates per sample made it possible to classify the insulation tested in order of performance in non-evaporation rate: 1st) shea cake with 90.81%; 2nd) cotton, 89.29%; 3rd) sand, 85.05% and 4th) air, 80.68%. In the light of a multi-criteria analysis by Thomas Saaty, based on more restrictive ecological and economic constraints, shea cake and sand were preferentially chosen. They made it possible to build a fuel storage matrix, called “Eco1-stoc”, which recorded an experimental non-evaporation rate of 91.53%. Therefore, the Eco1-stoc can be one of the solutions to be advised in operating conditions similar to those of Korhogo.
