As Bernard replied in one of his posts "HPQ before this news had 3 vertical lines of development (QRR for Silicon Metal, NSIR for nano for batteries, and Fumed Silica) and after the news release we still have them + the H2 project option".
The press release about the hydrogene project says that EBH2 has to be tested and proven to work before HPQ pays out anything. If it is not working, it cost nothing and HPQ still has its 3 vertical lines of development.
« IF » you were in before the press release, it would be foolish to get out now. But that is your choice.
