New equipment will not automatically store energy outdoors

What is one new approach to energy storage?

One new approach to energy storage is to create a network of small, energy-dense batteries in tens of millions of homes. Other new storage approaches include improvements to existing lithium ion batteries and schemes to store energy as huge volumes of compressed air in vast geologic vaults.

Could large-scale electricity storage be a game-changer?

In a world run mainly on fossil fuels, large-scale electricity storage promises to be an energy game-changer by unshackling alternative energy from the constraints of intermittence. Traditionally, power plants could simply burn more fuel when demand was high.

How do we store energy in the 21st century?

Let’s see how we store energy in the 21st century. It is much harder to store renewable energy than fossil fuels. Non-renewable energy only needs some ‘space’ to be stored, but green energy is stored in batteries, electric capacitors, magnetic storages – that have a lower efficiency. Read our article about storing solar power for decades.

What technologies does OE's Energy Storage Program focus on?

OE's Energy Storage Program performs research and development on a wide variety of storage technologies, including batteries (both conventional and...). Learn about the Energy Department's innovative research and development in different energy storage options.

How can energy storage help prevent power outages?

In regions with unreliable power grids, like parts of California, energy storage has become a key tool in preventing power outages. Large-scale battery storage systems can discharge energy into the grid during peak hours or emergencies, preventing grid collapse and keeping homes and businesses powered.

What can energy storage be a substitute for?

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.
