“Without solving the problem, it’s not going to be possible to make the planet sustainable,” he said. “I don’t think this is the problem of the next generation. This is a really big problem for our generation.” “It represents how serious the problem is when it comes to climate change,” Woo said. The project, he said, is"not just demonstrating our technology, it’s really going to be telling the story to the world that we have to fix this problem sooner than later.”
Ammonia is widely used for fertilizer, so there is already infrastructure in place for handling and transporting it. Ton for ton, it can hold more energy than hydrogen, and it can be stored and distributed more easily. It splits liquid ammonia into its constituents, hydrogen and nitrogen, then funnels the hydrogen into a fuel cell that generates electricity for the vessel without carbon emissions. The process does not burn ammonia like a combustion engine would, so it primarily produces nitrogen in its elemental form and water as emissions. The company says there are trace amounts of nitrogen oxides that it's working to completely eliminate.
