It enables energy recovery from agricultural waste or forest resources in rural areas isolated from the grid. The use of the syngas produced by gasification in spark-ignition engines offers the local population a simple, available, and lowcost technology to meet their electrical energy needs. However, the loss of engine performance when fueled with syngas, compared to gasoline operation, has prompted researchers to study the mixing of syngas with other types of fuel to overcome its low heating value. This article, therefore, presents a review of the use of syngas in sparkignition engines, either fully, or in a mixture as the pilot fuel or as an additive. A S.W.O.T. analysis is then conducted based on the results of the review with a focus on applications in rural electrification. The study highlights the contribution of syngas enrichment to the improvement of the quantity and quality of electrical energy produced. When syngas is used as an additive, its impact is not directly energetic but rather on the engine's lifetime, which is extended thanks to more stable operation and faster combustion. The review also shows that the use of syngas blends affects the quantity of pollutants in the engine's exhaust gas: CO, NOx and HC are reduced when syngas is enriched. However, CO and CO 2 emissions may increase when syngas is used as an additive due to the presence of these gases in the input. In the context of rural electrification, the use of syngas blends may improve the sustainability of the project through a better quality of service and a longer lifetime of the facility. However, a higher level of competence is required for people in charge of the site to control the production processes and the fuel-mixing. Finally, this study indicates the need for more research to explore the use of other fuels such as alcohol in the blend or the use of syngas blends in compression ignition engines.

Le système est composé d'électrolyseurs alimentés par des panneaux solaires photovoltaïques, un gazogène à lit fixe co-courant et un groupe électrogène. Afin d'augmenter l'autonomie de cette centrale, l'hydrogène, produit par l'électrolyse de l'eau, est mélangé avec du syngaz obtenu par gazéification de la biomasse. Les conditions météorologiques du site d'implantation de la centrale électrique et les caractéristiques de la balle de riz de Madagascar sont les données de simulation des productions d'hydrogène et de syngaz. Par rapport à l'alimentation de la centrale en syngaz pur, et en prenant comme hypothèse un stock initial de 60 Nm 3 de syngaz en vue de délivrer une puissance de 5 kW d'électricité, l'ajout d'hydrogène dans le syngaz permet d'augmenter deux heures d'autonomies avec 150 modules panneaux-électrolyseurs, et six heures avec 250 modules. Ainsi, l'hybridation de la gazéification, de l'électrolyse et de l'énergie solaire photovoltaïque apporte des améliorations à la production d'électricité. Le système d'alimentation proposé contribue à l'indépendance énergétique des zones isolées du réseau électrique national, et à l'amélioration du niveau de vie de la population rurale à Madagascar.
