According to the Vail Trail, the Vail resorts are considering using the biofuel in part because Aspen resorts have been using B20 in the snowcats for at least five years, even though the biodiesel costs a bit more. One issue, of course, considering where and when this biodiesel will be used, is gelling. Beaver Creek is doing a lot of research into fuel blends that will work in the cold temperatures, a spokeswoman told the Vail Trail. Some ski resorts also use biodiesel as a backup fuel for the generators that power the ski lifts.
