In an earlier post, I said the companies doing the work with USDOE were likely the 20 companies that had signed a CA, clearly this "bolded" statment corrects that.
BTW, ZEN does have a CA with the DOE and that report was not meant to hit the public (yet). So we were lucky to see that. But in the words of AE himself, they have better and more important work/studies ongoing right now that they hope they can release information on soon.
