The longest way to store energy

What is long duration energy storage (LDEs)?

Long Duration Energy Storage (LDES) is a type of energy storage system capable of discharging energy over long periods—ranging from several hours to days. When there’s an abundance of renewable energy, LDES allows us to store that surplus and use it during times when production dips.

How does energy storage work?

To discharge this electricity, steam is generated from the high temperature salt, which can drive a turbine. Compressed Air Energy Storage, Liquid Air Energy Storage and new, cheaper, more environmentally friendly battery chemistries are also being consider for long-duration storage.

Why do we need a long-term energy storage solution?

As renewable energy capacity grows, we must identify and expand better ways of storing this energy, to avoid waste and deal with demand spikes. Utility companies and other providers are increasingly focused on developing effective long-term energy storage solutions.

Is energy storage a good idea for small businesses?

On a smaller scale, energy storage is unlocking new economic opportunities for small businesses. By integrating renewable power with agriculture, individuals can store and supply excess energy, enhancing national grid resilience and diversity while generating profit. China has been a global leader in renewable energy for a decade.

Why is energy storage important?

This makes energy storage increasingly important, as renewable energy cannot provide steady and interrupted flows of electricity – the sun does not always shine, and the wind does not always blow. As a result, we need to find ways of storing excess power when wind turbines are spinning fast, and solar panels are getting plenty of rays.

What are the different types of energy storage?

Hydrogen Energy Storage: This converts excess electricity into hydrogen via electrolysis, which can later be used in fuel cells or combustion. It’s a great way to store energy over long periods and across various sectors. Liquid Air Energy Storage: Here, energy is stored by liquefying air and expanding it to drive turbines when needed.
