The 2024 Sahel Energy Summit showcased three emerging technologies specifically adapted to Ouagadougou's climate: These modular units store excess solar heat in ceramic bricks at 1,500°C - four times cheaper than battery arrays for overnight power generation.
[pdf] The system works without external heat sources, and utilizes an air compressor, a compressed air reservoir with a built-in thermal energy storage system, and an air expander.
[pdf] Air storage vessels vary in the thermodynamic conditions of the storage and on the technology used: 1. Constant volume storage ( caverns, above-ground vessels, aquifers, automotive applications, etc.)2. Constant pressure storage (underwater pressure vessels, hybrid pumped hydro / compressed air storage)
[pdf] The following steps outline how to calculate the Storage Efficiency. First, determine the total array capacity. Next, determine the gained capacity. Next, determine the lost capacity. Next, gather the formula from above = SE = (TAC + GC – LC )/ TAC * 100. Finally, calculate the Storage Efficiency.
[pdf] As of March 2025, the global energy storage market has ballooned to $78 billion, with lithium-ion batteries commanding 62% of installations . But here's the kicker—Brazil holds 18% of the world's lithium reserves yet contributes less than 5% to global battery production.
[pdf] These modular units store excess solar heat in ceramic bricks at 1,500°C - four times cheaper than battery arrays for overnight power generation. A pilot project at Ouaga 2000 Industrial Zone achieved 94% efficiency in converting stored heat to electricity.
