Tatton Consulting supported Kingston upon Thames-based energy storage developer Africa New Energies in its successful application to Energy Catalyst Round 9 – Early Stage, awarded £209,672 by Innovate UK for the project Exploring the feasibility of pumped hydroelectric energy storage (PHES) using seawater in South Africa.
About the funded R&D project
South Africa’s power crisis produces rolling blackouts of up to six hours a day, constraining economic growth and deepening inequality. This Energy Catalyst project assessed the feasibility of seawater pumped hydroelectric storage, which uses the ocean as the lower reservoir and removes the freshwater constraint on conventional pumped hydro.
