Long-Duration Energy Storage Milestones Achieved By Lockheed, Eos And Form Energy
The title of this post, is the same as that of this article on Energy Storage News.
Lockheed
I find it significant that Lockheed Martin have developed a new redox flow battery, which is a 500kW / 2.5MWh system.
Last year, the company had revenue of nearly sixty billion dollars, with a net income of over six billion dollars. They certainly have the resources and the name to make a big impression on the long-duration storage market.
Their GridStar Flow technology is also detailed on this page on the Lockheed Martin web site.
The page lists these features.
- Optimized for 6+ hours of flexible discharge
- Flexibility to switch between products to maximize revenue
- 100 percent depth-of-discharge with minimal degradation
- A design life of 20 years
- Ability to size energy and power independently
- Mildly alkaline, aqueous electrolytes that are safe (nonflammable, noncorrosive, stable)
- Competitive total cost of ownership
It looks impressive.
EOS Energy
EOS Energy can’t be doing badly, as they’re preparing to list on NASDAQ.
Form Energy
Form Energy are also reported to have had a $70 million investment.
Conclusion
It appears long duration energy storage is doing well across the pond.
My money would be on Lockheed to produce the most successful product.
