Not fossil fuel, so less carbon footprint.
There's a few buses here in Brazil which uses biomethane, and a few biomethane gas pipelines as well.
The thing is, Argentina just have a lot of natural gas production and infra.
Brazil natural gas are all offshore, on the coast, mainly São Paulo and Rio coast. And there is a lack of infra connecting these to countryside. We just don't have pipelines...
Brazil end up importing natural gas from Bolivia too, and soon, from Argentina Vaca Muerta.
And Brazilian natural gas are not cheap (but natura gas cars exists too).
Biomethane/biogas meanwhile, it's growing quickly because you can just use cattle, swine, and poultry manure, sugarcane, trash waste, etc. And well, Brazil is big with agriculture, so...
In 2024, 8,4% of electricity was using biomass too, for this exact reason.
PS: Reminder that most cooking gas in Brazil is all in a bottle, that you put in your home, which is LPG (liquefied petroleum gas, made of propane and butane). Most showers and heaters are all electric.
