FAQS

WHAT IS PUMPED HYDRO STORAGE, AND HOW DOES IT WORK?

Pumped hydro storage is a method of storing energy by using two water reservoirs at different elevations. During periods of low electricity demand, surplus energy is used to pump water from the lower reservoir to the higher one. When demand increases, water flows back down, passing through turbines that generate electricity. This method is highly efficient and has been widely utilized for decades to ensure grid stability. The process can be repeated numerous times, making it a reliable energy storage solution. The efficiency of pumped hydro systems generally ranges between 70% and 90%. Such facilities play a crucial role in balancing energy supply and demand on a macro scale.

WHAT ARE THE ENVIRONMENTAL IMPACTS OF ENERGY STORAGE TECHNOLOGIES?

The environmental implications of energy storage technologies can vary significantly based on the type of system employed. While pumped hydro storage can alter local ecosystems and water bodies, appropriate environmental mitigation strategies can alleviate some impacts. Conversely, battery systems, particularly lithium-ion batteries, raise concerns regarding the extraction and disposal of materials used in battery production. As the energy sector transitions towards sustainability, ongoing research is crucial focusing on improving the lifecycle management of battery technologies and developing eco-friendly alternatives that minimize ecological footprints. Thus, understanding and mitigating these impacts is imperative for fostering sustainable energy storage solutions.
