Quick Launch

Projects make electric energy generation from biomass feasible 

Asja announcement 
Cemig will commercialize the energy generated from biogas. The electric energy purchase incentive contract was signed with the Horizonte Asja Consortium.

The utilization of biomass in the production of energy has arisen as an alternative that can help to reduce the consumption of natural resources and fossil fuels, the burning of which results in the emission of gases that pollute the environment.

This will be one of the themes discussed at the II Innovation and Technology Forum, being held by Cemig, from May 30 to June 1. The meeting will be attended by professionals and researchers from the electric sector, universities and private initiative.

Among the research projects that will presented, one of the highlights will be the generation of electric energy by burning process gases from the carbonization of wood during the production of charcoal. The project is being undertaken by Cemig in partnership with Arcelor Mittal Bio Energia, which, together, have invested R$ 8 million. The charcoal produced comes from forests which were planted with the specific purpose of producing charcoal for use by the steel industry in the state of Minas Gerais.

According to Cemig Energy Alternatives engineer Cláudio Homero Ferreira da Silva, these gases, which currently are burned and discharged into the atmosphere, are used to produce energy and “as a result of the reuse of biomass waste in the process, fewer natural resources are consumed”. According to Mr. Silva, the generation of bioenergy, since it is a local solution, is not only part of distributed generation model, which the basis for smart grids, but can also make a big contribution during a future generalized energy crisis in the sector.

Also according to Claudio da Silva, future growth in the energy matrix will occur by means of wind, solar and biomasss energy sources, which means that Cemig is already operating within a context of sustainable development.

Clean energy

Cemig coordinates various projects together with the sugar-alcohol sector through the management of the construction of new transmission lines and substations in order to connect the sugar and alcohol plants to the electric system.

These initiatives allow the energy generated through co-generation, which utilizes sugar cane bagasse (a waste product from production), to be fed into the system, thereby increasing the contribution made by renewable sources to the national energy matrix.

In addition, by means of a pioneering initiative in the State and the third of its kind in Brazil, Cemig will commercialize energy generated using biogas, composed of methane and carbon dioxide, produced during the decomposition of garbage in a sanitary landfill.

Hired by the Belo Horizonte City Hall, the consortium explores for gas in a sanitary landfill in the state capital that was closed in 2007. A Biogas Utilization Station was installed at the site, along with a thermoelectric plant, which will generate energy utilizing the 21 million tonnes of garbage accumulated over the site’s 20 years in operation.
