The future of hydropower depends on finding ways to minimize its environmental footprint and ensure the health of our rivers.
The Promise of Pumped Storage Hydropower
Pumped storage hydropower (PSH) acts like a giant battery for the grid. During periods of low electricity demand, water is pumped from a lower reservoir to an upper reservoir. When demand spikes, the water is released back down, spinning turbines to generate electricity. This provides a flexible and reliable way to store energy and can help integrate variable renewable energy sources like solar and wind into the grid.
The beauty of PSH is that it can quickly respond to changes in demand, providing valuable grid stabilization services. It can also help reduce curtailment of renewable energy, which occurs when there is more electricity generated than the grid can handle. PSH projects can be either open-loop, which use natural bodies of water, or closed-loop, which use purpose-built reservoirs. Closed-loop systems have a smaller environmental footprint and are often preferred.
While PSH has many advantages, it also faces challenges. The initial investment costs are high, and finding suitable sites can be difficult. Permitting processes can also be lengthy and complex. However, as the need for energy storage grows, PSH is likely to play an increasingly important role in the clean energy transition. Its ability to provide flexible and reliable power makes it a valuable asset for a grid powered by renewable energy.
