Overview

Geospatial multi-criteria analysis reveals strategic underground energy storage zones across Morocco, highlighting prime salt formations near Casablanca and Agadir for gas and hydrogen storage.

Key Points

  • Assess Morocco's national-scale geological suitability for underground energy storage across salt formations, porous reservoirs, and abandoned mines using a spatial decision framework.
  • Integrated a geospatial database with a multi-criteria decision framework combining geological, structural, hydrogeological, environmental, and infrastructure metrics.
  • Applied the analytic hierarchy process (AHP) with consistency verification and sensitivity analyses to standardize and weight spatial indicators, including caprock integrity, fault proximity, depth, and seismic risk.
  • Salt-bearing formations near Casablanca and Agadir offer low permeability, strong sealing capacity, and high pressure resistance, making them optimal for compressed-air, natural-gas, and hydrogen storage.
  • Porous Paleozoic to Neogene reservoirs demonstrate promising yet site-dependent energy storage viability determined primarily by localized caprock integrity and reservoir quality.
  • Abandoned mines serve as viable local candidates for thermal and pumped-hydro energy storage, heavily conditioned by rock-mass stability, hydrogeology, and prior extraction damage.
