Julian Hunt researches the implementation of seasonal-pumped-storage plants to improve energy and water management.

In order to maintain greater control over the country's energy and water resources and reduce the vulnerability to changes in climate this postdoctoral research studies the Seasonal-Pumped-Storage (SPS) potential in Brazil and considers the optimization of its integration with hydroelectric dams in cascade downstream to increase overall hydropower generation.

Seasonal-Pumped-Storage (SPS) is a solution to store energy and water in daily, weekly, yearly and multi-yearly cycles. It stores potential energy and water when there is excess flow in the river, or when there is excess energy in the grid, pumping water from a storage reservoir in a major river to a large upper reservoir in parallel to the river. SPS requires a relatively small flooded area because the level of the dam can vary considerably more than in conventional dams.

Currently there are two main strategies to reduce the intermittence from wind, solar electricity generation sources and variations in hydropower generation. These are natural gas based generation and storing energy with SPS. Each technology will have benefits for different scenarios, however SPS and emits less CO2 than natural gas based electricity generation. Apart from storing energy, Seasonal-Pumped-Storage stores large quantities of water, which improve a country’s water supply security.

Additionally, this research evaluates the possibility of using the pumping capacity to transpose water to watersheds suffering from water stress, the possibility of using conventional hydropower reservoirs as waterways, connecting Brazil with its rivers, and for other activities that benefit from the multiple uses of water.
