Energy storage peak season is about to start

What is seasonal energy storage?

Seasonal energy storage requires the provision of electricity for several months, and this requirement can only be met with the help of technologies in which the stored energy capacity (energy density) is completely independent of the system power.

Why are energy storage systems important?

The use of energy storage systems is growing as the use of renewable energy sources expands, as these devices can absorb excess electricity generated by renewable energy sources and return it back to the grid during peak demand hours.

Can seasonal energy storage be economically viable?

To accommodate the use of this variable energy throughout the year the grid may benefit from economically viable seasonal energy storage to shift energy from one season to another. Storage of this nature is expected to have output durations from 500 to 1000 hours or more.

Are seasonal energy storage technologies limiting commercial deployment?

This paper reviews selected seasonal energy storage technologies, outlines potential use cases for electric utilities, identifies the technical challenges that could limit successful commercial deployment, describes developer initiatives to address those challenges, and includes estimated timelines to reach commercial deployment.

How long does energy storage last?

Storage of this nature is expected to have output durations from 500 to 1000 hours or more. Several emerging technologies may be viable for this application— including low-carbon fuels such as hydrogen and ammonia, thermochemical energy storage, or geo-thermal energy storage.

What is the future of energy storage?

Thanks to recent breakthroughs in the electric vehicle sector and the economic transition to greener energy, demand for ESS has skyrocketed. By 2030, energy storage needs are expected to triple from current levels .
