Ozinga Ready Mix Concrete
Ozinga is a leader in natural gas for the ready-mix industry. Out of 500 Class 7/8 vehicles, 112 are CNG, and Ozinga plans to convert the entire fleet by 2020. Among its 100 light-duty vehicles, more than a third are alternative fuels, mostly bi-fuel CNG, but also flex fuel, hybrid electric and dedicated CNG.
Ozinga Ready Mix plans to have its whole fleet running CNG by 2020. The trucks are not only cleaner, but quieter, a plus when working in residential areas.
It’s set to open its fourth CNG public fueling station by the end of the year, and has spun off a new company, Ozinga Energy, to help fleets build their own stations.
Pacific Gas & Electric
San Francisco, Calif.
PG&E is a major adopter of alternative fuels, running CNG, biodiesel, hybrids, electric and propane. It’s the largest utility fleet in the nation and the largest commercial fleet in California, and more than 30% of the fleet uses an alternative fuel or a high-efficiency fuel technology such as electric hybrids. PG&E runs close to 14,000 pieces of equipment, with more than 9,000 power units. The fleet includes 800 CNG (100 of them heavy-duty), 50 bi-fuel or dual-fuel CNG, 950 hybrid electric, 95 electric and 1,500 biodiesel.
Green Bay, Wis.
Paper Transport runs 80 CNG trucks out of 400 Class 7-8 trucks and tractors. Its fleet averages more than 7 mpg, with the newest trucks averaging over 8 mpg. The company has been installing trailer side skirts, both new and retrofit. It has a coaching and training program for drivers to improve fuel mileage. It’s been running class 8 CNG trucks for 3.5 years and have more than 5,000,000 miles on CNG. The company is currently working with customers on additional opportunities to convert more freight and trucks to CNG.
Port Authority of New York and New Jersey
Jersey City, N.J.
The Port Authority, which operates everything from airports and commuter trains to ports and tunnels, implemented its first environmental policy in 1993. About five years ago, it adopted a much more comprehensive sustainability policy, with the goal to reduce GHG emissions by 80% by the year 2050. Extensive adoption of alternative fuels is difficult because of the wide variety of equipment and the lack of fueling infrastructure or space to build stations. So the fleet’s main approach is adopting B20 biodiesel. In addition, the fleet does run some CNG, hybrids and flex fuel vehicles in Class 3-6. One hundred percent of all light duty vehicles purchased must be green.
A 2012 SmartWay Excellence Award winner, Prime limits truck speed to 65 mph and offers simulator training on how to drive for fuel economy. The fleet includes low-rolling-resistance wide-base single tires, trailer skirting, Trailer Tails, and Carrier IntelliSets on refrigeration units to maximize fuel efficiency. Specs call for the full efficiency package of the Cascadia Evolution, with synthetic low-friction oils and lubricants and auxiliary power units on all tractors. In the food grade tanker division, EcoTankHeaters on trucks reduce idle 30-50% when combined with APUs. In the flatbed division and tanker divisions, trailers with automatic liftable axles help reduce frictional drag when running lighter loads.
