My colleague Steve Ritterrecently attended a conference about electrofuels. Electrofuels are made by using energy from the sun and renewable inorganic feedstocks such as carbon dioxide and water, processes facilitated by nonphotosynthetic microorganisms or by using earth-abundant metal catalysts.
The conference was attended by researchers and at least one early adopter who is ready to give them a try. Cleantech Chemistry is pleased to have Steve’s report on what he learned. [Edit: You can read Steve's story on electrofuels in this week's issue]
FedEx operates more than 680 aircraft and 90,000 motorized vehicles, including delivery vans and airport and warehouse support vehicles such as forklifts. Dennis R. Beal, the company’s vice president for global vehicles gave a talk at the conference explaining why FedEx is open to many new fuel and other transportation technologies that likely would not reach the masses for years, if ever.
Although FedEx is a service company, “what we sell as a product is certainty—if you absolutely positively have to get it there, use FedEx,” said Beal. Beal gave a keynote talk during the Society for Biological Engineering’s inaugural conference on electrofuels research, which was held on Nov. 6–9, in Providence, R.I.
“That means we have a very high standard for our vehicles that pick up and deliver packages,” Beal added. “We have to be very careful in making business decisions to not negatively impact our ability to deliver certainty for our customers.”
With that philosophy, about 20 years ago FedEx starting taking a holistic view at transportation options, including battery and fuel-cell electric, hybrid, biofuel, and natural gas vehicles. “If it relates to fuel in any form, or alternative engines and drive trains, we are keenly interested,” Beal said.
The company has retrofitted delivery vans itself and partnered with vehicle manufacturers, electric utilities, electric equipment providers, and federal agencies on other fronts. FedEx even teamed up with the nonprofit group Environmental Defense Fund when pioneering the first hybrid electric delivery vehicles. Beal related that he and his colleagues have had a long climb up the learning curve searching for the most efficient transportation technologies that are safe, user friendly, meet driving range requirements, and offer a secure supply of affordable electricity or alternative fuel.
“We have tried a little bit of everything to see where these different technologies will and won’t work, Beal said. “We share the results with the rest of the delivery industry—the goal is to help advance the technology so that it will be widely adopted, not just for ourselves, but to help build scale to bring the cost down for everyone.”
FedEx has built its fleet to now contain 43 all-electric vehicles, 365 diesel hybrid and gasoline hybrid vehicles, and nearly 380 natural gas vehicles. In addition, the company has some 500 forklifts and 1,600 airport ground support electric and alternative-fuel vehicles in service.
The prototypes have a long way to go to be cost comparative with internal combustion engines, Beal said. For example, a typical all-electric delivery van costs $180,000 compared with $40,000 for a gasoline or diesel version. A consolation is that electric vehicles are 70% less costly to operate. “We believe the cost is going to come down and be economically viable in the long term,” Beal noted. “But given the logistics and needs of different regions—city versus rural and colder versus warmer climates—there is no one solution that fits all.”
FedEx plans to use a collection of approaches—gasoline, diesel, biofuel, hybrid, electric, fuel cell, and natural gas—and choose the right vehicle for each mission, Beal said. “What will drive adoption, once a technology passes the certainty test, is not that it is elegant, but that it also makes economic sense.”
