The Mauritania Development of Energy Resources and Mineral Sector Support Project, known as the DREAM Project, has been approved by the World Bank Group to transform the energy and mining sectors in Mauritania for a sustainable future. Led by Ibou Diouf, the World Bank Country Manager for Mauritania, the project aims to boost green hydrogen development, expand energy storage, and support critical reforms in the mining sector. The project will finance the country's first large-scale battery energy storage facility to leverage its abundant solar and wind resources for more reliable electricity, aligning with Mauritania's Mission 300 Energy Compact to achieve universal access to electricity by 2030. DREAM will also focus on estimating and promoting Mauritania's critical mineral potential through geological surveys and implementing the recently approved Green Hydrogen Law, making Mauritania a leader in critical minerals, green hydrogen, and energy storage. Additionally, the project will support institutional capacity, technical education, and workforce development, including targeted support for women in energy and mining. This collective approach reflects a commitment to accelerating Mauritania's long-term energy security goals. The project is a prime example of the One World Bank Group approach, showcasing alignment with other organizations like the International Finance Corporation (IFC) and partnerships with GIZ, the European Union, UNDP, and AFD for funding and expertise mobilization. Furthermore, support from programs like ESMAP, PPIAF, and KWPF has been crucial in preparing the project for implementation.
