Benefits of long duration energy storage

Power when you need it
Typical energy storage systems are generally only able to discharge power at full capacity for four consecutive hours on a given day. However, for 24/7 corporate facilities or municipalities with a great demand for the use of stored power at times where their renewable sources cannot feed more power in, the four hour max capacity is not enough. Long duration energy storage batteries can operate at maximum capacity for 6 to 1,000 hours or more depending on the chemistry and architecture of the engineered battery system.

Customizable chemistry and design architecture
Depending on your organization’s use case, the chemical components and design architecture of the energy storage system can be changed. Li-ion, vanadium flow batteries, or iron flow batteries are all potential options for storage with each having cathode types well-suited to different industries. In terms of sizing, energy storage systems can be engineered from 1 MW all the way to 100 MW in DC power.

Go off the grid
Installing solar at utility scale will not fully allow your organization to be energy independent, as ties to your local electric grid will still remain intact. Also, solar can only produce usable power during the day, and with most storage systems only allowing for full capacity to be used for four hours, the power of your solar array is not being fully utilized. However, long duration energy storage can change that. With an increased length of time to operate at max capacity, the opportunity is there to solely rely on stored energy instead of fossil fuel-driven power from your electric grid.

Making EV charging adoption at scale more feasible
The shift from OEMs to adopting electric vehicles has created a high demand for electric vehicles and EV charging stations. Large companies or communities who want to adopt EV charging fully need interconnected storage solutions. Otherwise, there will not be enough power available to meet the new levels of demand caused by constituents needing to charge their cars. Long duration energy storage solves this problem by making power available on demand for significantly longer periods of time.

Other products that work well together
Are you interested in installing a long duration energy storage system? Consider these factors first
- Are you a utility company or a private company with large storage needs? The type of application you need for your organization will affect the design architecture of the energy storage systems proposed.
- Do you want to install solar panels or EV chargers as well? Long duration energy storage can help you get the most out of both. Excess solar power generated throughout the day can be stored, and EV chargers can draw power from your energy storage system instead of the grid. Long duration storage makes it possible for solar power to be used and EV chargers to draw power anytime.
- Do you have a heavy need for power at times when solar or other renewable sources can't provide it? If your city or business has high peak demand after the sun sets, long duration energy storage could be a viable option to offset that. Typical energy storage methods will only discharge for about four hours, so long duration applications are a must if power is needed for longer than that period.
