RE: Navigating the World with the Hydrogen-Powered Ship
I'm having trouble accepting this when I think about the energy balance.
Both desal and gas compression are used in this system and they take a lot of energy, particularly desal. How is this more effective than using the solar energy to directly power the ship? Don't say storage - they have a battery integral to the system already.
There is no diesel used in the process, the power generated from the ship is from the three sources: wind, sun, and fuel cell. You can see the boat, unlike conventional boat, has no room for people to sit and chill on deck due to almost the whole top being covered by solar panels. The lithium batteries could have been the sole power source, but that would've made the shop weigh much more than the current 28 metric tons. The idea also is not to depend on batteries alone, which according to one of the or organisers, is not inexhaustible. The project is like a model to showcase the hydrogen economy, and kind of rekindle the interest into more sustainable means of hydrogen production and utilisation.
