This week, several websites have reported that the city of Oslo has announced plans to introduce buses that run on biomethane gas collected from two of the city’s raw sewage treatment facilities.
“Biomethane is a by-product of treated sewage. Microbes break down the raw material and release the gas, which can then be used in slightly modified engines.”
Initially, they plan to convert 80 of the city’s buses to run on the gas. If all goes well, the city plans to then convert the rest of the 400 bus fleet. Additional gas can be produced by household, restaurant, and animal waste.
According to RIPTA’s website, they maintain a fleet of 241 fixed route buses and utilize 2.5 million gallons of fuel per year. Imagine if Rhode Island was able to implement a program like Oslo’s? We have just over half the buses they do, and we certainly have plenty of waste to process.
In Oslo, “The city’s diesel public buses will only require minor modifications to their engines to run on methane, which is stored on tanks on top of the vehicles. The only noticeable difference will be how quietly they drive.”
Something to think about…
