What are energy storage technologies?

Energy storage technologies are valuable components in most energy systems and could be an important tool in achieving a low-carbon future. These technologies allow for the decoupling of energy supply and demand, in essence providing
 a valuable resource to system operators.

Why do we need energy storage technologies?

Energy storage technologies are also the key to lowering energy costs and integrating more renewable power into our grids, fast. If we can get this right, we can hold on to ever-rising quantities of renewable energy we are already harnessing – from our skies, our seas, and the earth itself.

What are energy storage systems?

Energy storage systems allow energy consumption to be separated in time from the production of energy, whether it be electrical or thermal energy. The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage).

Can energy storage be a key tool for achieving a low-carbon future?

One of the key goals of this new roadmap is to understand and communicate the value of energy storage to energy system stakeholders. Energy storage technologies are valuable components in most energy systems and could be an important tool in achieving a low-carbon future.

What is thermal energy storage?

Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry, and buildings sectors. TES technologies include molten-salt storage and solid-state and liquid air variants.

What is Energy Conservation & Energy Storage (ECES)?

Energy Conservation and Energy Storage (ECES) is one of 39 Technical Collaboration Programs within the International Energy Agency.
