Zinc8 Seem To Be A Surprisingly Open Company

Several energy storage companies, that I have looked at for this blog are secretive companies.

In The Mysterious 150-hour Battery That Can Guarantee Renewables Output During Extreme Weather, where I pointed at an online article of the same name, the secrecy is in the headline. Look at the web site of the company involved; Form Energy and it reminds me of a term used in the 1970s and 1980s to refer to non-existent software – vapourware. Or one of my older favourite phrases – All fur coat and no knickers.

I have developed disruptively innovative software and other products and understand, the need for secrecy. But there is a need for a balance between secrecy and information.

As an example, one of the products, I have highlighted here, could be ideal for one of the followers of this blog. They will be investigating the product, as I have found enough information to enable them to decide, that contacting the company will not be a waste of time.

Some companies in innovative energy storage development like Highview Power and Hydrostor have posted informative YouTube videos about their technology, but others just rely on the same endlessly repeated phrases.

When I looked at the Zinc8 web site, I thought they were another company dealing in the same phrases, as there are two on the home page.

  • Zinc8 is redefining long-duration energy storage.
  • The leader in zinc-air battery technology.

But they are a lot more open, than the home page might suggest.

Looking up zinc-air battery on Wikipedia, gives a lot of information, that is understandable. This is the introductory paragraph.

Zinc–air batteries (non-rechargeable), and zinc–air fuel cells (mechanically rechargeable) are metal–air batteries powered by oxidizing zinc with oxygen from the air. These batteries have high energy densities and are relatively inexpensive to produce. Sizes range from very small button cells for hearing aids, larger batteries used in film cameras that previously used mercury batteries, to very large batteries used for electric vehicle propulsion and grid-scale energy storage.

I instantly thought, if a technology can be both non-rechargeable and rechargeable and useable in applications from hearing aids to vehicle propulsion and grid-scale energy storage, the technology must have something. I also worked in a non-ferrous metals factory as a teenager and know that zinc is easy to handle.

I then looked at their technology page

  • There is a detailed explanation of the technology.
  • They stress their patents and certification.
  • They show how a system can be expanded.
  • They list the major technological advantages of the system. Robust, safe, scalable etc.
  • They claim 20,000 operating life hours and 8+ operating hours.

They also finish off by giving an energy capacity cost of $45 per kWh.

I tend to think, that they have found a quirk in zinc-air technology, that they are exploiting, by some good old-fashioned innovative engineering.

I shall be watching Zinc8 and the other zinc-air battery start-ups.

  1. […] 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. […]
