¿How does it work?

Once the rainwater is collected in race-pond pools, microalgae (Chlorella vulgaris) is added to grow in a the circulating water. When the microalgae is ready, the current stops and the excess water is drained by a piping system that later on will produce potential energy from the movement of the water,  being helpful to produce energy that will power up the station through small hydroelectric power plants. The algae that is left behind in the pools is then dried by sun and additional heat sources, this remaining product is the biomass that absorbs CO2, a harmful greenhouse gas, and nitrates as a nourishing to finally be able to produce hydrogen.

As the water pass by the hydroelectric power plants and the biomass is already collected, the elements are ready to be used to produce hydrogen through electrolysis. This electrochemical process uses electric power to separate the molecular composition of the water and the biomass while those are added to an ionized substance with the presence of a catalyst  into the electrolytic tank where the process take place. Therefore,the hydrogen gas is produced and is ready to be injected into the metro motor, resulting on a sustainable fuel that does not harm the environment.
