We've been out talking, and we would agree that hubs will attract economic investment. That's based on what we're seeing internationally.
Hydrogen valleys are called clusters, but generally what we're talking about is two or more companies getting together and sharing a common production facility. It could be as simple as that, or right up to very large clusters, where you have multiple applications connected by a pipeline and so on.
The key thing about them is that they are going to enable low-cost hydrogen, which will attract investment for people deploying trucks, buses and so on. It will provide locations where you can do demonstrations and research, which will allow you to generate the highly skilled individuals Rob referred to. We're going to need a lot more of them. It will also allow technology companies, such as Grace's, to have locations where they can show their technology, to have customers they can rely on and to perhaps not be in mission critical mode so they can work the bugs out of these things and allow themselves to move forward.
It has been shown that starting a cluster will tend to stimulate this type of activity, and all of that leads to jobs and investments coming to the country.
