The production of hydrogen from the decomposition of water is indeed one of the most important hydrogen production methods. In fact, this reaction requires not only a catalyst, but also sunlight (solar energy). It is thermodynamically possible for water to decompose into hydrogen and oxygen by absorbing light energy, but the rate is extremely slow under normal conditions of temperature and pressure. The role of the catalyst is to accelerate the photolysis reaction. Therefore, the reaction cycle in question is basically the process of utilizing solar energy, that is, solar energy is converted into hydrogen energy, which does not violate the law of conservation of energy.
After five years of development, a new small high-energy generator has been successfully developed at the Sao Paulo Technology Business Incubation Center. He is currently in phaThis is the end of the experiment. The generator can be used for lighting in homes, schools and hospitals, and will be used in hydrogen cars in the future.
This project is a product developed by Electrocell and Eletropaulo of the Technology Business Incubation Center with research funds financed by the State of Sao Paulo.
According to the company's chemical engineer, this small generator is powered by diesel like the current generator, but it will replace the current generator. It is characterized by its small size and ease of installation. large energy production, no interruption, no pollution. The generator combines hydrogen and oxygen to convert chemical energy into electricity, producing only water as a waste product.
The company plans to install and test it in a hospital or call center in October this year.
Over the past two years, Eletropaulo company has invested 1,7 million reais in this project. It was developed so that the residence remains environmentally friendly, efficient and sustainable. Nowadays, the lifespan of a general generator is 10 to 12 years and it requires maintenance during this period. The new generator can be used without interruption for 20 years.
Although the hydrogen enters the generator after passing through the dryer, there will always be a certain amount of humidity, so the temperature of the cold water used in the generator must be higher than the hydrogen temperature. , otherwise the hydrogen will condense when it gets cold, because water is not allowed inside the generator.
Generators are mechanical devices that convert other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines or other electrical machines to convert the flow ofwater, air flow. , fuel combustion or atomic nuclei The energy produced by fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
