Long Duration Energy Storage (LDES)
Power is only as reliable as the hours behind it. We deliver storage from 6 hours to 100+ hours, designed for utility scale reliability and long-term planning.
6 hours to 100+ hours duration
No system degradation, designed to last for centuries
Water-based system, operates on H2O
Why Long Duration Energy Storage
When demand rises, duration becomes the constraint
Energy demand keeps increasing. The hard part is not generating power, it is keeping power available when timelines stretch beyond the usual window. Once you cross six hours, storage stops being a feature and starts being infrastructure.
Long Duration Energy Storage (LDES) is how you reduce curtailment, smooth peak demand, and plan for reliability without overbuilding generation.
What We Offer
6 hours to 100+ hours, delivered as a scalable platform
We offer long duration energy storage from 6 hours to more than 100 hours. At six hours and beyond, our pricing outperforms the typical lithium-ion “stacking” approach that tries to force short-duration systems into long-duration use cases.
If you are planning for duration, this is built for duration.
6 hours to 100+ hours duration
Competitive economics at 6+ Hours
Built for life cycle planning
Scales from 3MW to gigawatt deployments
Supply Chain & Environmental concerns
Why some teams are rethinking lithium-ion inputs
Some stakeholders prefer to avoid lithium-ion chemical supply chains due to broader concerns tied to materials extraction and processing, including:
Concerns commonly raised include:
- Water contamination risks from chemical processing
- Air pollution from emissions and particulate matter
- Environmental disruption, including soil degradation and habitat loss
- Radioactive waste risk in certain deposits that include thorium or uranium
- Displacement impacts on communities near mining and processing regions
Frequently Asked Questions
We have the experience. Let us help.
What is long duration energy storage?
Long duration energy storage is energy storage designed to deliver power for extended periods, typically beyond four to six hours. It is used to support reliability, peak demand, and grid stability when generation does not match load.
Why does duration past 6 hours matter?
Past six hours, many projects see costs rise quickly if they try to extend short-duration systems through stacking. Long duration storage is designed to serve these longer windows without forcing a mismatch between design and use case.
How does your system avoid degradation?
Our system is designed with no system degradation and is intended to last for hundreds of years, supporting long-term life cycle planning.
What does water-based operation mean for project risk?
Using water (H2O) can simplify safety planning and reduce exposure to hazardous chemicals. Many teams evaluate this as part of permitting, operations, and ESG requirements.
What land area is required?
A 3 MW deployment requires 2 acres or less
Can projects scale over time?
Yes. Deployments scale in 3 MW pads and can expand as demand grows, up to gigawatt-scale buildouts.
