W: Thanks for meeting with me today, Diego. Our firm's been contracted by a ferry company to design a hydrogen-powered boat. They're hoping to cut down on their carbon emissions with a boat that runs on clean energy. M Hmm. A hydrogen power source is going to need a lot of space. Since ferries usually transport cars, I'm concerned about where we'd place the hydrogen source. W: Actually this ferry would give tours. So it won't be carrying vehicles, just passengers. M: Then maybe we could store the hydrogen on the deck? W: Possibly. Could you research that before we meet with the ferry company? M: Absolutely.
