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.
Proposed Merger Will Make Zinc Battery Developer Eos Energy A Public Company
The title of this post, is the same as that of this article on pv magazine.
This is the introductory paragraph.
EOS has executed a letter of intent for a merger with a SPAC — which would result in EOS becoming a publicly listed company. Investors seem fascinated by energy storage this year, the long-duration variety in particular.
The two companies are described like this.
EOS Energy Storage
EOS Energy Storage is a private zinc battery developer with the chance to go public via a merger with a special purpose acquisition company.
The company has a comprehensive web site.
Riley Principal Merger Corp II
B. Riley Principal Merger Corp II (BMRG), a special purpose acquisition company listed on the New York Stock Exchange, and Eos have executed a letter of intent for a merger which would result in Eos becoming a publicly listed company.
The article, then states that energy storage is the big thing with investors this year.
The article makes some interesting points and anybody thinking about investing in these technology stocks should read it.
Conclusion
With this activity around EOS, it could be they are a company to watch, but we’ve had share bubbles before.
Eos To Install 4MWh Of ‘Safe’ Zinc Battery Technology – At Giant Oil Refinery
The title of this post, is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
Eos Energy Storage will deploy a megawatt-scale, behind-the-meter zinc hybrid cathode battery energy storage system for a large oil refinery in Greece, claiming it be a validation of the safety and environmental benefits of the novel technology.
EOS Energy Storage seem to have developed a zinc battery, that could work along similar lines to the zinc battery produced by zinc8, that I wrote about in Zinc8 Seem To Be A Surprisingly Open Company.
The Energy Storage News article gives more details on the battery and its design.
- This battery is rated at 1 MW/4 MWh, so compared to some, it is quite small.
- It uses a zinc-halide oxidation/reduction cycle to store and output energy.
- The battery is made from five components, all of which are abundant, ethically sourced and recyclable.
- An order for a 40 MWh system has been placed.
- EOS claim to have numerous pilots and demonstrators in use.
Could it appear that using zinc batteries are a feasible method of storing energy, as two companies both appear to be successful at delivering systems?
