The Regional Transportation Commission (RTC) of Washoe County has been investing in alternative fuel buses since 2014 to reduce carbon emissions and combat rising fuel costs. Currently, more than a quarter of RTC’s 70 bus fleet is composed of electric-battery buses.
However, the RTC has discovered that electric-battery buses have some limitations that hinder their effectiveness. Therefore, the RTC is now investing in hydrogen fuel-cell buses, which are considered superior technology. The first two hydrogen fuel cell buses arrived last week to RTC’s Sutro Street location.
“Hydrogen fuel cell buses are pretty cool because they are electric buses, but instead of having to charge them overnight, they get charged from the hydrogen fuel cells themselves. The batteries get charged from that. And, that gives them the ability to travel about 300 miles per charge, verses 100 or so for when you use the EVs,” said Regional Transmission Commission of Washoe County, Government Affairs Officer Paul Nelson.
Another advantage of hydrogen technology is scalability. While RTC needs a new charging station for each new electric battery bus, just one hydrogen filling station can support 10 to 50 buses.
Road to zero-emission buses proves challenging for Minnesota transit agencies.
Vendor issues, performance in subzero temperatures and charging station maintenance are among the challenges transit agencies face as they try to decarbonize their fleets.
Representatives from Edmonton and Strathcona County Transit said that aside from expected teething challenges, the pilot buses are working well. Testing data indicate they can handle the cold and have a similar range to diesel buses (and perhaps better than the troubled electric bus fleet in Edmonton).
“When we were doing testing we shadowed, or ghosted, a diesel bus in service to get some range, and we had sandbags in (the hydrogen bus) to mimic passenger loads,” Wade Coombs, director of transit for Strathcona County, said. “All the data to date has been showing that it is very comparable to a diesel bus in the distance you can drive in the day.”
Eli nuo akku voimalinjojen huonot puolet puskevat ammattiliikenteessäkin pintaan. Oikean elämän kokemukset menee hyvin yhteen tänne linkkaamami AC Transitin tekemän pitkäaikaisen testin kanssa.
Liebreichin hydrogen ladderi on heikko esitys.
Saksalainen kaupunki päätyy vetybusseihin. Erikoista tässä hankkeessa on se, että vihreä vety hankitaan paikallisesti ja elektrolyysin “hukkalämpö” pyritään käyttämään hyväksi rakennuksien lämmittämisessä.
