Innovative Solutions Help Buses Green Up
With assistance of $85,396 from the Newfoundland and Labrador Green
Fund, the St. John's Transportation Commission will install mini hybrid
devices on six of its buses and help reduce its environmental impact.
Along with a reduction in fuel consumption, this system will also help
remove debris from the engines' radiators, resulting in more efficiently
operating engines.
"Every action to reduce greenhouse gases represents not only a
positive environmental move, but also a wise business decision," said
the Honourable Charlene Johnson, Minister of Environment and
Conservation. "We have many wonderful examples of how businesses and
organizations are working together with government to foster and
implement sustainable ideas. I applaud the St. John's Transportation
Commission for this initiative which can potentially reduce greenhouse
gas emissions by upwards of 67 tonnes annually."
The commission will install a mini-hybrid thermal system on six of
their buses, replacing the traditional hydraulic fan and alternator
which are run by placing a demand on the engine. The system comprises
eight efficient, electric, controllable fans and a high-efficiency
brushless alternator. Along with the reduction in fuel consumption the
system will provide, the fans will also be reversed periodically to
clean debris from the engine's radiator, thereby helping the engine run
more efficiently. While the thermal device will not convert the buses
into conventional hybrids, the system will help achieve approximately 50
per cent of the fuel savings of a typical hybrid at 10 per cent of the
cost.
"We are continuously searching for solutions to help mitigate our
carbon footprint on the city, and this project complements the many
other measures we have taken such as our exhaust retrofit program and
anti-idling policy in our bus storage area," said Judy Powell, General
Manager of the St. John's Transportation Commission. "We anticipate our
ridership increasing over the next five years, so these actions are
necessary. We want to continue to develop additional green approaches
for our transit system."
