Hydrocane is a sugarcane like plant that can be harvested and then, through an extraction process, Hydrogen Gas can be produced and used to make lighter-than-air travel possible. In it's unrefined state hydrocane is a much more potent source of fuel for lighter-than-air travel than extracted hydrogen gas, but it produces a by-product that is damaging to the environment. Hydrocane doesn't actually produce hydrogen gas on it's own, it converts the pure hydrogen captured from the air and water around it through a process similar to Photosynthesis, and turns it into chemical energy so that it can be used to fuel the plants's activities.
