Around the planet, hundreds of millions, if not billions, of people use buses to get around towns as well as cities.
While they are incredibly well-liked as well as often cheap forms of transport, they do have an environmental impact, with emissions coming from exhaust pipes being a serious issue.
Change can be afoot, however. While many buses are run on diesel, companies as well as city authorities around the planet are, slowly however surely, turning to cleaner sources of fuel.
from the Chinese city of Shenzhen, for example, there are more than 10,000 electric buses, while Aberdeen in Scotland can be home to a fleet of hydrogen-powered vehicles.
In London, plans are in place to introduce roughly 3,000 “ultra-low emission” double-deckers to central London by 2019 as well as more than 250 zero emission single-deckers by 2020. As of today, more than 2,0 diesel-electric hybrid buses are on the capital’s streets.
from the U.S., one business has been designing as well as developing battery-electric buses using a view to boosting both efficiency as well as the environment. Founded in 2004, California-headquartered Proterra commenced designing its first prototype the same year, as well as sold its first three buses in 2009.
Ryan Popple, the company’s CEO, told CNBC’s “Sustainable Energy” of which the company was constantly looking to improve designs as well as performance. “Every day engineers at Proterra are trying to figure out how to raise energy density, how to reduce (the) weight of the vehicle as well as how to make the drive train even more energy efficient,” he said.
Proterra’s Catalyst bus design can be made with what the business describes as an “an advanced carbon-fiber-reinforced body” as well as a high efficiency electric drivetrain. Continuous progress can be key to the business. Last September, a Proterra bus drove just over 1,101 miles on an individual charge.
“Two years ago the maximum distance we could do on a track was about 250 miles,” Popple said. “A year ago the item was 0 miles as well as then last fall we broke the record, the item was 1,100. So we’re just seeing massive step improvements in capability.”
