Domestic energy storage demonstration projects

What is long-duration energy storage (LDEs)?

This long-duration energy storage (LDES) project aims to be a key demonstration of critical power backup of an acute care hospital in the U.S. and provide resiliency in a region that is increasingly at-risk for significant power outages due to fires, storm surges, floods, extreme heat, and earthquakes.

Why is multiday energy storage important?

Project Summary: Multiday energy storage is essential for the reliability of renewable electricity generation required to achieve our clean energy goals and provides resiliency against multiday weather events of low wind or solar resources.

Where is Alliant Energy demonstrating a CO2 long-duration energy storage system?

Locations: Pacific, WI Project Summary: Through the Columbia Energy Storage project, Alliant Energy plans to demonstrate a compressed carbon dioxide (CO2) long-duration energy storage (LDES) system at the soon-to-be retired coal-fired Columbia Energy Center power station in Pacific, Wisconsin.

What is a CO2 energy storage project?

The project plans to store excess energy from the grid that can be deployed when needed, taking excess energy from the grid and converting the CO2 gas into a compressed liquid form, which reduces the typical complexity and costs associated with storage.

How can LDEs technology reach liftoff?

To reach liftoff, LDES technologies could go through three phases of commercialization with in-field projects: Deploy many small demonstrations to create a visible set of commercial-scale case studies across the market landscape.

Could a successful demonstration enable market adoption of urban electric power's LDEs system?

A successful demonstration could enable market adoption of Urban Electric Power’s LDES system by proving decreased technology risk, reducing demand on grid infrastructure through reduced peak demand load, and reducing total costs of installation and operation as compared to a Lithium-Ion system.
