At times of low energy demand (with associated low costs) the High-Density Fluid is pumped uphill to elevated storage tanks, using abundant renewable energy. As energy prices rise (due to rising demand or curtailment of renewable generation) the fluid is released and passes through turbines, regenerating electricity to supply power to the grid.
Because we use a high-tech fluid with a density 2.5x that of water, RheEnergise projects can operate on low hills rather than high mountains.
Projects are 10MW to 50MW of power. This means that they can be connected onto existing grid infrastructure and can be co-located with other renewable energy projects.
