"No followers, only leaders." This is the slogan of Brazil's hydrogen fuel cell bus development plan. Following the United States, China, Germany, and Japan, Brazil became the fifth country to invest in the operation of hydrogen fuel cell buses.
The first hydrogen fuel bus is put into use
Recently, the Brazilian Ministry of Mines and Energy and the City of São Paulo Urban Transport Corporation launched the first hydrogen fuel cell bus in Latin America in São Paulo. With a length of 12 meters and an authorized passenger capacity of 63, the car will travel through the main street between Sao Mateus and Jabaquara in Sao Paulo with a one-way distance of 33 kilometers and a daily mileage of [reviewed picture forum] of approximately 278 kilometers.
It is understood that the car uses a hydrogen-powered hybrid power system developed by the City of São Paulo Urban Transport Corporation. According to CaRLos Zundt, head of the city transportation company, the vehicle hybrid system is equipped with hydrogen fuel cells and traditional batteries. Hydrogen fuel cells can travel 300 kilometers per gas, while conventional batteries can travel 50 kilometers; and diesel buses are 5 to 8 years old. Compared with the service life, the hydrogen fuel bus has an average service life of up to 20 years and a maximum speed of 70 kilometers per hour.
Zundt said: "Different from diesel engines, hydrogen-fueled engines are zero emissions. When hydrogen and oxygen react, they generate electricity and produce water, which does not produce carbon dioxide and nitrogen oxides that pollute the environment."
According to experts, 480 kinds of pollutants emitted by diesel vehicles cause air pollution, Zundt said: “At present, air pollution in São Paulo is mainly caused by diesel vehicles, so hydrogen fuel technology is provided for future zero-emission public transport. It's possible."
Hydrogen fuel buses are 10 times more expensive than traditional diesel buses, but its designers believe that they can save costs through other channels. Zundt said: "Hydrogen fuel buses reduce emissions, thereby reducing the incidence of respiratory diseases, and every year in Brazil's big cities spend a lot of manpower and resources for the treatment of respiratory diseases."
The first person to benefit is the driver of a hydrogen fuel cell bus. Bras Minuceli is the lucky one. Bras Minuceli said: “What makes me happiest is that the bus is quiet and quiet, and the previous diesel engine always sounded 'squeaky.' This car is also easy to drive, and it’s not as exhausting as it used to be. It's up."
"The use of hydrogen fuel technology, the bus's energy economy reached 90%, only 900 grams of hydrogen per kilometer consumed, the remaining 10% can be recycled into the recycling system." Zundt said.
As an accessory project, on July 1st, the first hydrogen fueling station built by Petrobras was also completed at the headquarters of the urban transportation company in Sao Paulo. The hydrogen refueling station can produce 120 kg of hydrogen per day at a pressure of 450 kg/cm2. With more vehicles put into use, the reserves of hydrogen refueling stations will further expand.
Following Rio de Janeiro, Brazil’s other major city, Rio de Janeiro, will also have a hydrogen fuel cell bus.
Pakistan government pushes hydrogen fuel economy
As we all know, the Brazilian ethanol industry system is perfect, and now the Brazilian government wants to make a difference in renewable energy.
Brazil is one of the world's largest bus production sites. The annual production of buses exceeds 50,000, and the three largest commercial vehicle manufacturers in the world, Mercedes-Benz, Volvo and Scania, have production facilities in Brazil. As car ownership has increased year by year, some parts of Brazil have been heavily polluted. For example, Cubutao is the most polluted area and has experienced mudslides caused by acid rain. It is understood that 90% of air pollutants can be attributed to motor vehicles, especially diesel vehicles used in most major cities.
To this end, in November 2007, the Brazilian government announced plans to launch a hydrogen fuel cell bus and plans to operate five hydrogen fuel cell buses in Sao Paulo for the first time. The project invested US$16 million in support from the United Nations Development Programme, the Global Environment Facility and the Research and Project Finance Agency.
The launch of the Sao Paulo City hydrogen fuel cell bus is just the first step in this project. Brazil will establish a set of urban public transportation solutions nationwide. The Brazilian Ministry of Mines and Energy EdISon Lob?o pointed out that the hydrogen fuel cell bus project has consolidated Brazilian expertise in the field of renewable energy. He said: "This project has been successful. The Brazilian Ministry of Mines and Energy and its partners have made great efforts. The use of hydrogen fuel buses will further promote the development of the Brazilian economy."
José Lima, secretary-general of the Ministry of Mines and Energy of Brazil responsible for oil, natural gas and renewable fuels, said: “The successful use of ethanol and biodiesel in Brazil has created the conditions for the use of hydrogen fuel as a renewable energy source. From now on, we The mission is to establish an economic structure around hydrogen fuel in Brazil.†He also said that the plan is not only for Brazil, but also for the entire Latin American region.
Zundt also stated that after the first batch of hydrogen fuel cell buses are put into use, Brazil will add 200 hydrogen fuel cell buses after road tests. With the further promotion of hydrogen fuel cell buses and the expansion of market demand, the bus model is expected to achieve large-scale production, which will further reduce production costs and provide opportunities for future exports to other countries. But Marco Andre Fraga, a researcher at the National Institute of Technology (INT) in Brazil, said that it may take 15 years or more for Brazil to promote hydrogen fuel.
