FREQUENTLY ASKED QUESTIONS

WHAT IS ENERGY STORAGE?

Energy storage refers to the capture of energy produced for use at a later time. This technology can store energy generated from various sources, primarily renewable energy sources like solar and wind, as well as traditional energy sources. Different methods of energy storage include lithium-ion batteries, pumped hydro storage, gravity-based storage, and thermal energy storage. Each method has its pros and cons, and the efficiency, capacity, and scalability can differ significantly based on the chosen technology.

The importance of energy storage in modern energy systems cannot be overstated since it not only facilitates the management of energy supply and demand but also enhances grid reliability. With the increasing deployment of renewables, energy storage becomes integral to balancing intermittent energy generation and ensuring that electricity is available whenever it is needed. As a result, energy storage plays a vital role in the transition towards a more sustainable and resilient energy future.

HOW DO ENERGY STORAGE SYSTEMS WORK?

Energy storage systems operate by storing energy at times of excess production and releasing it during peak demand periods. The fundamental principle varies according to the technology employed. For instance, in battery storage systems, chemical reactions occur to store electrical energy, while in pumped hydro systems, the potential energy of water is harnessed by elevating it to a higher elevation reservoir.

Battery energy storage systems are often employed alongside renewable generation, capturing surplus energy produced during peak production hours and storing it for later. When energy demand spikes, the stored energy can quickly be dispatched back to the grid. Similarly, pumped hydro systems use gravitational potential energy; energy is used to pump water uphill during low-demand periods, and released to generate electricity during high demand, effectively providing a quick and efficient response to energy needs.

WHAT ARE THE BENEFITS OF ENERGY STORAGE?

Energy storage offers numerous benefits that contribute to a more sustainable and reliable energy future. Primarily, it enhances grid stability by providing a buffer against fluctuations in energy supply and demand.
