hydroelectric power plant
The study Carbon Balance in Reservoirs (Balcar), made jointly by the Eletrobras group and ten Brazilian research institutions between 2011 and 2013, with 11 hydroelectric plants found that, except for Balbina, "most of the Brazilian hydroelectric emits very little carbon dioxide, a much smaller proportion than any thermal power plant, however good it may be. And some reservoirs showed that absorb carbon. "Information is the head of the Division of Environmental Studies and Planning of the company, Maria Luiza Milazzo.
Among the reservoirs that absorb gases responsible for issuing greenhouse effect of the atmosphere, the study highlights the funnel, in the Southeast, and Xingó in the Northeast. "This was a very good and interesting surprise." Four field surveys were carried out in each plant, in compliance with the seasons.
Of the surveyed plants, eight were in operation - Balbina, Tucuruí Itaipu, Serra da Mesa, Xingó, Tres Marias, Funnel and secrecy - and three under construction - San Antonio, Belo Monte and Battle. Data were collected on carbon dioxide, nitrous oxide and methane. The latter has the power to gas global warming four times greater than carbon dioxide, said Maria Luiza.
The Balbina dam, located in Rio Uatumã in the Amazon was earlier studied by the biologist Alexandre Kemenes, the National Institute for Amazonian Research (INPA), published in 2007 in the journal Research in Geophisical Letter geophysics. The survey found high emissions rates that hydroelectric, ten times the emissions of a thermal power plant fueled by coal.
The head of the Division of Environmental Studies and Planning of Eletrobras reported that, on balance, the Balcar study shows that the hydroelectric plants tend to absorb greenhouse gases from the atmosphere. "Itaipu, for example, is a hydroelectric who has almost no issue." She stressed that a gas fired power plant will emit less than a [plant] Thermal oil or coal. "That's why the dam is still as advantageous over other type of energy we need to power the electric sector paí.s.
Maria Luiza said that hydropower contribute to the fight against climate change. "The energy matrix of the Brazilian electricity sector is very clean due to the large number of hydroelectric power we have. If we use a different font type, it would be much more pollutant is gas, coal, oil, diesel or any other fossil fuel. It would be much larger issue. "
The Research Center of Electric Eletrobras (Cepel), who led the study, is now formatting the Balcar 2. According to Maria Luiza, the goal is to follow up the research in the three areas where hydroelectric projects were under construction and also in other plants. With it, you can have a solid database in order that field trials are time consuming, expensive and laborious, he added.
