We can start making hydrogen now. We are making hydrogen. We're one of the largest clean hydrogen producers in the world.
It is not as far advanced as battery technology; there's no question about that. We need to be smart about how we deploy that and start putting this into the hubs I mentioned. You concentrate and get the good economics in place and you can start deploying buses today. We can already start deploying light-duty vehicles. We can start deploying trucks that are going to be coming in the near future. When you talk to the major truck producers, they know they have to decarbonize trucking and they know that's going to have to be done with hydrogen.
We need to get ready. That can be done cost effectively.
