RE:IEEE SPECTRUM DEC 2021 p.50Many competitors in space...potentially. Most can be examined by a simple google search but these leave many unaanswered questions about their stated processes and ultimate success. Most are not truly in commercial phase, just development and testing and some with pilot sites. Seems to me those with greatest financial backing will most likely succeed on a grand scale. Neometals in news today with its steel company association. IMO cannot see how AMY will progress without similar integrated and financial support and more rapid pace of commercial development.
