no, calix make magnesium hydroxide, and they have been having trouble selling it for years, so they are trying to pretend their technology is capable of making green steel. This is a fallacy it is not capable of making green steel, but they are very good at getting people to invest in their r&d projects that will keep
their staff employed and hopefully they will find something that will make their magnesium hydroxide work properly and then they can be a water business that they have failed at. Calix making green steel is about as likely as superman being real.
