The combustible cell technology utilizes hydrogen and oxygen in a highly efficient reaction which generates only energy and water, without the presence of polluting gases. This type of energy could present the solution for the reducing pollution in the great metropolises and for the strong dependence on fossil fuels.
The Brazilian energy matrix counts on 90% participation of renewable energy sources, amongst which water represents the greatest wealth.
According to the Ministry of Mines and Energy, 12% of the whole world´s hydro resources are in Brazil. Nevertheless, little or almost nothing has been done in terms of obtaining the hydrogen which emanates from this resource.
The principal challenge to the implantation of hydrogen on a large scale is economic. The production of pure hydrogen on a large scale is up against a high cost and low availability of the methods for obtaining it. In addition, the storing and transport of hydrogen are problematic. All this creates a very high final fuel cost which is an obstacle for short term implantation.
In Brazil, one initiative is that of hydrogen production from ethanol. Research groups are working on the development of this technology.
Another project due to start this year is the hydrogen bus, which works on electrolysis and will circulate in Sao Paulo.
The object of this task will be to propose instruments to stimulate the participation of hydrogen in the Brazilian energy matrix, and consequently the extension of its application to the region of Latin America.
