To meet the growing demand for low-carbon fertilizers, we present a GIS-based framework that identifies promising locations for renewable ammonia production in Kenya. The approach links high-resolution spatial resource assessments with a transparent multi-criteria decision analysis, combining the Wind and Solar Implementation Probability indices with an Analytical Hierarchy Process. More than thirty resource, infrastructure, and restriction criteria feed into a transparent scoring scheme and are weighted through expert and stakeholder consultations. The analysis operates on a nationwide raster of 50 m × 50 m and applies realistic hard constraints: distance to water ≤ 50 km, distance to major roads ≤ 25 km, and wind speed ≥ 7 m s−1 at 150 m hub height. The analysis reveals substantial land potential for renewable ammonia and pinpoints four priority regions exhibiting distinct strengths. Turkana South offers favorable cost structures, Mombasa provides superior infrastructure and water access, Turkana Central benefits from extensive contiguous land areas and minimal land-use conflicts, which are ideal conditions for large-scale development and Kisumu is well-positioned for regional market integration. Results show that site suitability is shaped not only by the quality of wind and solar resources but also by implementation conditions, accessibility, and socio-economic factors—particularly access to water and proximity to the grid. The methodology is transferable to other African countries and to additional hydrogen derivatives, providing a scalable framework for the pre-selection of Power-to-X sites.
