Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.
A dynamic energy storage solution, pumped storage hydro has helped ‘balance’ the electricity grid for more than five decades to match our fluctuating demand for energy. Pumped storage hydro (PSH) involves two reservoirs at different elevations.
In fact, investing in pumped hydro storage could save up to £690 million a year on the pathway to net zero. This figure is from a study by independent researchers. It found that 4.5GW of new long duration pumped hydro storage with 90GWh of storage could save up to £690 million per year in energy system costs by 2050.
Note: PHS = pumped hydropower storage. The transition to renewable energy sources, particularly wind and solar, requires increased flexibility in power systems. Wind and solar generation are intermittent and have seasonal variations, resulting in increased need for storage to guarantee that the demand can be met at any time.
For the energy sector, storing excess renewable energy is a significant advantage. It means the sector can rely less on fossil fuel-based power plants. This will help mitigate greenhouse gas emissions. This positive environmental benefit is important to energy companies like SSE. Pumped hydro storage also offers grid stability and flexibility.
Pumped hydro storage is set to play a significant role in shaping the future of energy storage. It has the potential to revolutionise the way we store and use renewable energy. With it, we can create a cleaner and more sustainable world for future generations.
