NNLX has good technology, but the price will not take off until there is evidence of a business plan.
NNLX does not have the wherewithal to build out industrial-scale hydrogen conversion facilities. They need to partner with someone who does. To do that they need to define how NNLX and that partner will work together--licensing? jv? something else?
NNLX is at the "theory into practice" stage--there's a lot of heavy lifting to be done before they have revenues, let alone earnings, to show for their technology.
Until NNLX articulates a business plan covering this, and show evidence of progress along that plan, the price will probably stagnate.
