LIGHTEN-IO structures a regional network for green hydrogen in the South-West Indian Ocean (SWIO), combining scientific research, high-resolution climate data and international cooperation.
In a context of strong demographic growth where more than 50% of the African population lacks access to electricity, producing green hydrogen by electrolysis powered by renewable energies is a leading option for the ecological transition of this region.
Solar and wind potential of South-West Indian Ocean islands (SWIO) for green H₂ production.
Climate and topographic data at ~1 km spatial resolution.
Indian Ocean Commission (IOC) network — universities, meteorological services, governments.
Artificial Intelligence for statistical downscaling of climate projections.
Structured around two main work packages — scientific research and project management & dissemination.
Identify stakeholders and design a concerted strategy for green hydrogen deployment.
Generate climate, topographic and land-use data at high resolution (~1 km).
Feed practical applications and specific case studies with network stakeholders.
Project management. Promotion, dissemination and exploitation of results.
Covering scientific research and operational project management.
