Just a lot of points that were not addressed in that article, John.  I suspect that there were more questions raised by the article than answered, but I am glad to be advised of the possibility of Long Duration Energy Storage because it alerts readers that there are developments in Energy Storage that they need not only anticipate but also to actively look for...as LAC investors we need to keep an eye on this particular segment of Energy Storage market as it effect the lithium market.  I was left with one predominant emotion after reading the article.... "Where's the beef?"   Where are the details?

Actually the topic:  Long Term Energy Storage  has many different permutations and is not limited to just one specific avenue.  Long Term Energy Storage has been around for decades in many different forms so it isn't really a new topic.  The newest form of Long Term Energy Storage is one we should acquaint ourselves with in more detail, but there are other forms of Long Term Energy Storage ( each with its own limitation such as bulk, weight, lack of portability, cost, etc.) and we need to keep those older forms of Long Term Energy Storage in mind as well.  Below is an article link to an article that enumerates some of those additional Long Term Energy Storage modalities that have been kicked around much longer:
