Petrobras explores green energy
In Brazil, Petroleo Brasileiro (Petrobas) has signed an agreement with Gas Verde S.A. to supply 200,000 m3 of biogas per day.
Replacing natural gas, the biogas will be generated by Gas Verde, from the Jardim Gramacho landfill in Rio de Janeiro to the Petrobras Duque de Caxis plant.
It is thought that the project will reduce greenhouse emissions. As well as helping to recover the mangrove close to the landfill, the project aims to recover the plant life that used to grow on the 3 million m2 landfill site. The living conditions of people living nearby will hopefully be improved and 2 billion litres of liquid waste will be treated every day.
In similar news, Petrobras’ Juiz de Fora power plant, also in Brazil, will become the country’s first ethanol-fueled power plant.
Since 31 December the plant has been using ethanol on an experimental basis. Now, in its efforts to create alternative sources of power, a 45MW turbine has been adapted that can be used with ethanol or gas.
The ethanol refinery is the newest addition to the company’s already long line of power plants totaling 7,028MW, including 14 natural gas power plants (5,820MW), 12 fuel oil power plants (892MW) and 16 small hydropower plants (316MW).
There has been a 30% decrease in nitrogen oxides since the plant started using ethanol, 13 days ago.
Brazil produces the largest amount of ethanol in the world due to its production of sugar cane.
