EEStor, Lockheed Martin to Collaborate on Military and Homeland Security Applications

After quite a period of silence, there is some news on EEStor today. Maybe the company is for real and we will finally get some more meaningful information. Working with Lockheed Martin certainly gives them some credability. It looks like the company is about a year behind on its initial production schedule. Several previous posts on EEStor can be found in the energy storage category. The bold emphasis in the press release is mine.

The entire lockheed Martin press release:

Lockheed Martin [NYSE: LMT] has signed an exclusive international rights agreement to integrate and market Electrical Energy Storage Units (EESU) from EEStor, Inc., for military and homeland security applications.  Specific terms of the agreement were not disclosed.

EEStor, based in Cedar Park, TX, is developing a ceramic battery chemistry that could provide 10 times the energy density of lead acid batteries at 1/10th the weight and volume.  As envisioned, EESUs will be a fully “green” technology that will be half the price per stored watt-hour than traditional battery technologies.

“Lockheed Martin has a wide range of innovative energy solutions for federal, state and regional energy applications,” said Glenn Miller, vice president of Technical Operations and Applied Research at Lockheed Martin Missiles and Fire Control.  “The EEStor energy storage technology provides potential solutions for the demanding requirements for energy in military and homeland defense applications.”

EESUs are planned as nontoxic, non-hazardous and non-explosive.  Since the EESU design is based on ultra-capacitor architecture, it will allow for flexible packaging and rapid charge/discharge capabilities.  EESUs will be ideally suited for a wide range of power management initiatives that could lead to energy independence for the Warfighter.

“Lockheed Martin continues to focus on providing our Warfighters with new and innovative technologies that will make their jobs easier,” said Lionel Liebman, manager of Program Development – Applied Research at Lockheed Martin Missiles and Fire Control.  “Our ruggedized BattPack™ energy storage unit generated considerable interest at the Association of the United States Army Annual Meeting in October 2007 for its potential for fuel savings in vehicular silent watch applications.  The potential of an even safer, smaller and more powerful EESU in BattPack™ would significantly enhance the Warfighter’s capabilities.”

EESU qualification testing and mass production at EEStor’s facility in Cedar Park is planned for late 2008.

EEStor, Inc., of Cedar Park, TX, originally developed its solid-state EESU technology as a longer lasting, lighter, more powerful environmentally friendly electronic storage unit for a wide variety of applications.  EEStor’s vision also includes EESU facilitating the conversion of wind energy and photovoltaics into primary electrical energy providers and increasing the role of renewables for increasing energy production.  Its CEO and president, Richard Weir, is also the inventor named on its EESU principal technology patent.

Headquartered in Bethesda, Md., Lockheed Martin employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.

An article in the Toronto Star by Tyler Hamilton reported that ZENN's stock had jumped 22% on the announcement by Lockheed Martin. ZENN, an early investor in Eestor, has the exclusive rights to use EEStor's storage system in small vehicles.

In another press release EEStore announced that Morton L. Topfer has joined the EEStor, Inc. Board of Directors.

Company background, per press release:

EEStor, Inc. is developing a solid-state electrical energy storage unit (EESU). This technology anticipates having a wide variety of applications with the added benefit of being longer lasting, lighter, more powerful, and environmentally friendly. EEStor's vision also includes EESU's facilitating the conversion of wind energy and photovoltaic technology into primary electrical energy providers. This intern will vastly increase the role of renewable energy in the world's energy production markets. EEStor has 1 patent issued, with an additional 17 patents in process.

Read a detailed interview about EEStor with expert from Lockheed Martin:

Great article, that gives me hope for EESTor, but very vague on details.

Details such as existing prototype performance.

I've worked with military contractors, and done some work for Lockheed, and they were sharp. I can't believe that they wouldn't understand the issues that many experts have brought up across the web.

I think this may be real, and I worry that cars just took a backseat to military.

[Charles Barton]

I wish I could believe in the EEStor story. But there are a lot of red flags hanging out there. EEStor was suppose to deliver a prototype to Zenn Motors in November. So far there have been no official announcements that it has arrived. Morton L. Topfer was a member of the EEStor Board. According to the Tyler Hamilton Topfer left the EEStor Board last summer. His unexplained departure was never explained. The press release announcing that he was joining the EEStore Board made no mention of his former association.

Hamilton has provoked an interesting discussion thread on EEStor:

I'm not a cap expert for sure, but I see a startling amount of green flags.

I started as a skeptic two years ago, but now I find myself as one of the wacko's that think EESTor is real.

The red flags I see are:
1. Experts say it won't work
2. They missed a delivery date to Zenn

The first one had me worried because I trust the experts in the field. I wouldn't even be following EESTor except that I ran across the name of Weir and started looking into it. I think he's clearly legit.

The second red flag I'm not even worried about yet. I work closely with manufacturing. Even parts that are simple and non-experimental can take months or even years to put into production.

If it keeps right on slipping I'd question EESTor, but at this point it's just a couple of months. We don't even know for sure that it has slipped.

The green flags are:
1. new patent ap's coming out
2. Weir's record
3. Topfur's return, he's a legitimate person
4. Lockheed contract
5. production facility construction
6. purity verification

To me it's clear that they've set up a production line. If EESTor is a scam they are, by far, the coolest scammers in recent history.

To fool Zenn doesn't mean much, but to have fooled Kleiner and Lockheed Martin, two companies that know the technology inside out, that would be impressive.

[DaveMart]

I'd read it that the technology works or is hopeful, but they are having issues with costs,
The military is way less sensitive to cost than the car industry.

[Paul H.]

So it's 1/10th the weight/volume, and 10x the energy storage. 100x the energy density w.r.t. weight and volume? Is that right? Instead of 40 Wh/Kg (Lead Acid), It's 4000??!! That can't be right?

[Paul H.]

oh, 10x the energy density (which is independent of volume), so why mention at 1/10th of the volume? That's a mistake?

[bigTom]

I'm a little less skeptical than I had been. I had only heard that 10x storage density claim, and not having seen the lead-acid comparison, had assumed they were comparing against LiIon. Perhaps 10x of lead-acid density is doable?

I think putting 3500volts across a very thin dielectric sounds very risky. All it takes is a single pinpoint, anywhere in the system to breakthrough the dielectric, and you have a catostrophic short. Of course you can cut back the voltage, but energy scales as volatge squared, so storage density could get unimpressive pretty quickly if they have to seriously backdown on the voltage.

[Rick]

until I see it on the street, I don't believe it. I want these ultra cap (or whatever they are) equipped ZENNs at a local dealership available in 5 different colors and available for test drive and purchase today. Until that happens I don't believe anything.

[John F.]

The erroneous 100x energy density notion derives from a nonsensical and misleading phrase in the press release: "10 times the energy density of lead acid batteries at one-tenth the weight and volume."

That's a confused expression. Energy density is energy/weight. Having already stated the energy density in the first part, the bit about "1/10th the weight" doesn't clarify anything.

If they had left out the word "density" (i.e., "energy" instead of "energy density"), then the phrase would hold together semantically, and would indeed mean 100x energy density (and 100x volumetric energy density). Perhaps that's why it's being misunderstood. The subphrase of "1/10th the weight and volume" only makes sense if the first was "energy" not "energy density", so readers delete the word "density" in their mind.

But it isn't 100x, obviously. The patent spec makes it clear that it's 10x the energy density of lead acid.

What's odd is that the same patent puts VOLUMETRIC energy density (energy/volume) at over 20x lead acid. I wonder why this press release is now suggesting 10x. Since the writer or editor of this passage is clearly confused about these metrics, my best guess is that 20x is correct.

[Chan]

I will wait and see until EEstor's sample delivery, while my friend asserts his 500-50K Wh/Kg ultra-cap/battery like "Blackhole".

[Harvey D]

10X* the energy density over the current common lead battery would mean something between 300 Wh/Km and 400 Wh/Km and is very doable. From previous claims, the ESStor Unit could do much better than that. 20X (or slightly more) the energy density of a common lead battery was indicated.

* (10X) The recent Electrovaya Li-On Mn Series does it already i.e about 330 Wh/Km and may be tweaked to about 450 Wh/Kg within a year or two.

Handling the higher voltage (3500+ volts within the unit) may represent an interesting technical challenge but is doable at an acceptable cost.

[Gregor]

Well, so much for our hope in EEStor. Now that the government has got them tied up they can continue to work with Big Oil and the car manufacturers to keep us in the internal combustion engines.

You don't honestly think that the governments would allow this kind of technology to foil there oil plans, do you....revenue, power, war, etc. do you? There is a lot of tax money at stake here.

[Gregor]

Charles Barton, I went to that blog and the "Anonymous" fellow seems to know what he is talking about. This EESTor is just one big scam.

Thanks for your reference.

This scam will rate up there with Enron.

[Greg Woulf]

I participated in that thread and I don't think it's a done deal at all.

All of the problems from Barium Titenate caps stem from two problems. The first is interference of electrical fields and the second is purity of the material to keep the dialectric coefficient high.

Weir's specialty is coatings for hard drives that shielded the drive from electrical fields.

If he's found a way to keep the barium titenate pure and coat it in a way that he can scale the caps up then all the 'impossible' arguments go away.

Then it comes down to more a question of how he'll manufacture it, and how stable it is.

[Duane Navarre]

"If he's found a way to keep the barium titenate pure and coat it in a way that he can scale the caps up then all the 'impossible' arguments go away."

I believe they are going to use nanotech
to take care of this issue.

Exactly how I am not sure, but in some
other articles I have read about eestor,
that was what I picked up from it.

Such as:

http://www.autobloggreen.com/2007/03/10/nanotech-strikes-again-university-of-arizona-creates-new-capac/

http://en.wikipedia.org/wiki/EEstor#Status

It may not happen as soon as everyone wants,
and it may have unforeseen issue, but
breaking new ground in tech usually does.

[Cyril R.]

Energy density claims are fairly consistent with some laboratory work by others on ultracaps (for example, MIT's).

Electrochemically we've recently seen lithium nanowires supposedly at over 1000 Wh/kg (claim was 10x current lion). Perhaps something similar would work for Na replacing Li. Li-S is already over 400 Wh/kg in a proven product.

I recently hurt myself when I was trying to repair my camera. The light's capacitor decided to discharge on my finger. That was unpleasant.

Eestor has to have good safety measures. Especially in the event of a collision. Those units would be modular but still... You don't want that kind of energy discharging on your body. Very similar to a modest lightning strike I'd imagine.

[Brian H]

XH150 has designed a vehicle with LiIon buffered by ultracapacitors which is also interesting.

BTW, Gregor: the LM contract is for military and homeland security devices only. It does not inhibit any automotive or consumer applications. It just means LM gets exclusive use for making their infantry battery packs, etc. The military is exploring lots of options in this area, such as tiny fuel cells powered by methane, etc.
