Oslo Buses to Run on Sewage

Posted by samzenpus on from the stinking-tailpipes dept.

Mike writes "Rather than let their sewage go to waste, the city of Oslo recently announced that it plans to cut carbon emissions by converting 80 public buses to run on biomethane generated from raw sewage. The city plans to adapt two sewage plans with the technology this September, and the new biogas buses will be quieter and will cut 44 tones of C02 per bus per year."

    It's fortunate that methane is odorless, then.

    It's always good to see methane captured and burned into carbon dioxide, since CH4 (methane) is a far stronger greenhouse gas than CO2. On top of that, you can do useful work with the energy—like power a bus fleet—which saves even more carbon emissions.

    Gas-driven (not gasoline) buses has been around for at least a decade. It's just that they use a different type of gas.

    Transportation is the usual methane capture project killer. Landfills and wastewater treatment plants are typically located away from densely populated regions, for reasons apparent to anybody who's ever been downwind of one. As such, there typically isn't as well developed as it would have to be to make a project work.

    There are, of course, exceptions. Puente Hills Landfill in LA can generate 50MW. A more typical landfill can generate only a fraction of that.

    Yes, but oil-drilling rigs and refineries are often located even farther away, yet gas still get in from them...
