Yes he has stated it won't be the only solution. That's already known. As it's not cost effective for extra long distances (eg. Australia to Europe). However for shorter distances (Australia to Asia or around Europe) it appears to be very cost effective/Simple/efficient. A lot less capital costs to set up than Ammonia or liquid. Its a complete green solution using Ballards fuel cell system for ships. Yes definately a chance for first mover advantages. But in my opinion I can't see why European countries would go to the effort to convert it back and forth through ammonia for short distances. This is such a simple elegant solution with minimal infrastructure set up.
