I would like to add to that. Ports represent a really great opportunity to deploy hydrogen, because you have the drayage trucks. We are pushing our products in the port of Vancouver so we should see, hopefully, some drayage trucking operation shortly.
You have the yard trucks in the port. A lot of vehicles operate in the ports, and those vehicles are similarly operating on hydrogen in California ports and also in Europe.
The last are the vessels. The marine vessels are a bit more challenging because of their size and their certification.
What we have at Ballard today are six projects for ships that are being built using hydrogen, and solar ships. We are looking at ferries for passengers or barges for inland navigation. It's a beginning where we can see the growing role of hydrogen. Actually, we see more and more shipyard operators coming to us and saying, “We need to reduce our emissions. How can hydrogen play a role in that? What is the role of fuel cells?”
There is a really big change that we have noticed in that sector, I would say, in the past 18 months.
