Egypt's Century-Old Desert Power Dream Revived
22 Jul
Summary
- Engineers proposed a canal from the Mediterranean to Egypt's Qattara Depression over 100 years ago.
- The plan uses elevation differences to generate hydroelectric power indefinitely.
- Unresolved environmental impacts and excavation scale stalled the project.
Over a century ago, engineers envisioned channeling Mediterranean seawater into Egypt's Qattara Depression to generate electricity. This plan, first conceptualized around 1912 and further detailed in 1927, proposed utilizing the vast elevation difference for a self-sustaining hydroelectric power source. The depression's sub-sea level status made it ideal for such a gravity-driven scheme.
Significant engineering efforts occurred in the 1970s, with a German-led team conducting detailed planning. A 55- to 100-kilometer canal or tunnel would be required to bring seawater into the depression. Once filled to a level 60 meters below sea level, an underground power station could operate.
Despite serious planning, the project never materialized due to the immense scale of excavation and environmental uncertainties. The same evaporation that enables continuous power generation also risks creating an increasingly saline lake, posing ecological challenges. Alternative proposals, like using Nile floodwater or desalination, also remain undeveloped.
Periodic interest in the Qattara Depression project persists, drawing comparisons to the Aswan High Dam. However, fundamental issues of cost, excavation scale, and environmental impact continue to prevent this century-old dream from becoming a reality.
