Santa Catarina has signed its first contract for the commercial injection of biomethane into the state's piped gas network. The agreement, signed between H2A Bioenergia, SCGÁS, and VOSSKO, marks the beginning of the supply of this renewable fuel on a commercial scale through the state's existing distribution infrastructure.
This breakthrough is occurring in a market that is still largely unexplored in the country. According to ABREN (Brazilian Association of Waste Energy), Brazil utilizes less than 2% of its biomethane production potential.
The fuel can be obtained through the anaerobic biodigestion of waste from pig farming, cattle farming, poultry farming, and agro-industrial activities. After undergoing purification and quality control processes, biomethane achieves technical characteristics equivalent to those of natural gas of fossil origin.
This compatibility allows renewable fuel to be transported through the existing network and directly replace natural gas, without the need for significant adaptations to equipment or industrial processes. In this way, waste that represents an environmental liability in the field can be converted into a source of energy.
“The first injection of biomethane into the distribution network demonstrates that the use of this fuel on a commercial scale has become a reality in Santa Catarina,” says Adilson Teixeira Lima, CEO of H2A Bioenergia.
Waste gains energy value.
Biomethane production is especially relevant in Santa Catarina due to the presence of animal protein chains and the volume of waste generated by agricultural activity. Biodigestion contributes to the proper treatment of these materials and enables the decentralized production of a renewable fuel.
According to Yuri Schmitke, president of ABREN, the contract could pave the way for new projects in the state. "We are confident that this will be the first of many sales contracts stemming from biomethane plants that utilize swine manure."
In addition to industrial use, biomethane is emerging as an alternative for decarbonizing heavy freight transport. The fuel can gradually replace diesel in truck fleets, especially in operations with regular routes and access to refueling infrastructure.
The production process also generates biofertilizers with agronomic value, which can be returned to rural properties. The model thus creates a cycle for utilizing waste: the organic material gives rise to renewable fuel and products that can be used again in agricultural production.
