Case Study: Fleet Portfolio

Case Study: FedEx – Fleet Portfolio

For more than a decade, FedEx has evaluated the right vehicle portfolio for each of its operating companies. In doing this, the company follows a three-tiered approach to improve vehicle fuel efficiency – Reduce, Replace, and Revolutionize – which allows it to help develop vehicle technologies while making the best use of the conventional vehicles.

  • Reduce – optimizing routes and driving more efficiently to reduce miles on the road and vehicle emissions.
  • Replace – upgrading the vehicle fleet with more efficient, advanced technology diesel vehicles.
  • Revolutionize – utilizing alternative fuel vehicles, investing in the development of cleaner technologies and advocating for fuel-efficiency and greenhouse gas standards.

The Revolutionize component allows the company to engage in a variety of cross-sector and public-private collaborations to identify and pilot new technologies to improve fuel efficiency. In the past, FedEx has worked with the Environmental Defense Fund to engineer the first commercially-viable hybrid-electric vehicles for company and commercial use. This led to FedEx calling for the first-ever fuel efficiency and greenhouse gas standards for conventional commercial vehicles in the U.S. and subsequently, the passing of the Energy Independence and Security Act of 2007, which legislated fuel efficiency and greenhouse gas regulations for medium- and heavy-duty vehicles.

Today, the company is working with manufacturers to further advance the industry. Beyond vehicle testing, technological innovations include making hybrid and electric drivetrains more affordable and scalable, improving the fuel economy of conventional internal-combustion-engine vehicles and developing an infrastructure for vehicle electrification. Pilot programs include liquefied natural gas Class 8 trucks at FedEx Freight, hydraulic hybrid pick-up and delivery vehicles at FedEx Ground, and hydrogen fuel-cell baggage tow tractors at FedEx Express, along with other projects and technologies.

Case Study: BNSF Railway – Solar Array

The BNSF Railway Stockton Solar Array is located in Stockton, CA on land owned by BNSF Railway. The solar array was placed in service September 2013. It is an 800 kilowatt (kW) ground-mounted solar system that includes more than 3,330 photovoltaic (PV) solar panels covering approximately 3 acres. BNSF Railway’s Stockton energy use is 1.8 million kilowatt-hours (kwh) annually, with 75% of this energy used at night. The energy generated from the solar array is estimated at 1.3 million kwh annually. Net metering and variable pricing optimize BNSF’s financial returns, with surplus energy generated by the solar array during the day sold at premium rates, and lower cost energy purchased from the grid at night.

Case Study: Biogas Recovery

Case Study: Biogas Recovery – Smithfield Foods, Inc.

Smithfield Foods, Inc. implemented biogas recovery and used biogas as a fuel source in two 700 HP boilers at its Tar Heel Facility in North Carolina. The system typically reduces the facility’s natural gas use by 10 percent. The project has added benefits:

  • Combusting the biogas, as opposed to venting it to the atmosphere, reduces the facility’s carbon emissions.
  • Covering anaerobic digesters and capturing biogas for energy recovery reduces odors.
  • Storm water intrusion from covered anaerobic lagoons provides wastewater treatment savings.

The system includes a synthetically lined and covered anaerobic basin with gas collection piping, blowers, condensate system, gas pipeline, flare and dedicated biogas fuel trains for the boilers. The boilers also operate using natural gas. This technology has been in use at the Tar Heel facility since the 1990s.

Case Study: P&G – Wind Turbine

In 2011, Procter & Gamble (P&G) installed its first wind turbine at a P&G Petcare place in Coevorden, Netherlands.  P&G owns the 2.1 megawatt hour turbine and installed it on company land. The project had an internal rate of return that met P&G internal hurdles for capital spending. The electricity is sold to the grid to take advantage of the local feed-in tariff incentive. RECs are repurchased so the plant continues to own the environmental attributes.
