.E-Truckin’ Ahead

The electrified cargo era is here

Work used to be simple for the California Department of Transportation: widen highways, fill potholes, build new freeways.

Alas, those quaint days
are gone.

To get an idea of what planners must prepare for, state officials recently hosted a demonstration of a drone air taxi that will require devising a “highway above the ground,” said Reza Navai, a Caltrans transportation planner. “If you think transportation on the ground is complex….”

Such sci-fi-like transit is one of many high-tech changes coming as California implements its planned electrification of transportation to radically reduce greenhouse-gas emissions. The path to “zero,” as in zero-emission vehicles, extends well beyond flying taxis and the 5 million electric cars the state hopes will drive its roads by 2030. Everything—everything—will be replaced with an electric analog: from boats, planes and trains to delivery vans to farm tractors and even forklifts. The to-do list stretches as long as California’s seemingly endless blacktop, with freight as a major challenge.

The state’s transportation gurus envision technology that pings driverless vehicles with an automated message when they stray from their lanes, “smart” roads that charge electric cars and trucks as they pass and an electrified Interstate 5, the West Coast’s main freight corridor. California has already widened its painted lane stripes to six inches from four so self-driving vehicles can better “see” the road. Ultimately, the highways themselves will be redesigned and constructed with different materials.

California’s transportation agency, which updates its master plan every five years, is currently preparing a look at 2050. While officials cannot predict each new technological wrinkle, Navai said, “we must be able to consider all possibilities.”

To achieve a carbon-free transportation future, California will need to cover a lot more ground in a short time frame.

“If California’s trying to be a leader, we have to go as fast as possible,” said Lew Fulton, who studies sustainable transportation at UC Davis’ Institute of Transportation Studies. “Policies are critical to try to speed this up and try to push the envelope, and get all the manufacturers scared enough that they start producing what we need. Carrots and sticks. Carrots being pricing and incentives, sticks being regulatory.”

The state has spent more than $1 billion in the last five years to encourage research, subsidize the exchange of internal combustion vehicles for zero-emission options, formulate cleaner fuels and expand vital charging infrastructure.

It’s working with technology firms to clean up heavily polluting marine fuels belching from container ships at California ports, and state funds are helping Central Valley farmers, who are on a waiting list to replace their aging farm equipment with fuel-efficient models and to receive rebates.

Such projects may get a boost from California’s Tesla-owner governor, Gavin Newsom, as budget negotiations wrap up this month. His proposed spending plan includes nearly $24 billion for all aspects of transportation, a 6 percent increase.

Few transportation modes have clean-engine options as advanced as those for passenger cars. Buses are the exception. The Chinese company BYD, manufacturing electric buses in Lancaster, is the largest in North America and has produced more than 300 buses, including nearly half of the Antelope Valley Transit Authority’s pool.

The city of Los Angeles has pledged to convert its bus fleet—second-largest in the country—to electric by 2030, though mechanical and performance problems plagued the rollout of its BYD vehicles. Many other transit districts have similar goals that include school buses. The financial burden of those commitments is softened by state vouchers for up to $200,000 toward the purchase of each zero-emission bus.

The availability of some electric all-terrain recreational vehicles, farm machinery and specialty equipment such as cherry-pickers and front-end loaders has produced niche markets. Generally, though, the readily available transportation technology stops where the road ends: Electrification of trains, planes and ships is less advanced.

A state analysis found that ocean-going vessels still depend on heavily-polluting marine fuels and, aside from nuclear-powered engines for military use, zero- and near-zero technologies are not currently available. Among smaller vessels, San Francisco Bay’s famed Red and White fleet added a new hybrid-electric ferry this week.

Ships docking in California’s ports frequently forgo using diesel generators to operate and instead plug into shore-side electric power. But even when stationary, big vessels have a massive appetite: A nine-cylinder ship engine—five-stories tall and weighing 1,500 tons—can produce enough power to run 30,000 homes for a year.

But trucking is the major freight challenge for California. More than 97 percent of the state’s big rigs operate on diesel fuel, which is highly polluting and a significant contributor to detrimental health effects on those residing near transit corridors. Currently only a handful of electric or hybrid heavy-duty truck options exists, mostly prototypes.

“I see 100 percent electrification as being far off; there just aren’t any of those trucks on the road,” said Brandon Taylor, director of transportation for GSC Logistics, a freight company operating at the
Port of Oakland.

Freight represents a transportation problem somewhat of our own making: We desire—and order online—more and more products, for delivery right now. With each mouse click, delivery vans and trucks flood the state’s highways and neighborhood streets, dispatched to cover what supply-chain planners call “the last mile” of residential delivery.

About 20 percent of trips in the United States are, in fact, less than a mile. But it’s too late to shut off the merchandise-delivery tap, and freight accounts for about a third of the California Gross Domestic Product.

The influx of these trucks and vans runs counter to one of California’s bottom-line goals: to reduce not just the number of vehicles on roads but also, and more critically, the miles they travel. The mid-sized delivery vans taking the package handoff from heavy-duty trucks are turning over odometers at a dizzying rate; in Southern California, an estimated 85 percent of truck traffic is dedicated to local deliveries and short hops.

The future is likely to include on-demand trucking. Predictably, there’s an app for that, Uber Freight, which launched in California in 2017. It’s one of a handful of load-matching apps that connect shippers with smaller, more nimble trucks plying local routes. The system is intended to increase efficiency and decrease total miles driven. Additionally, electric trucks can return to a home base at night to be recharged.

Big rigs in California aren’tt subject to the smog inspections that have applied to cars since 1982, partly due to early pushback from trucking companies and insurmountable complexities involved in regulating out-of-state vehicles. But that could change: A bill advancing in the Legislature would create smog checks for big diesel trucks.

The state will need to retrofit highways to allow charging of electric freight trucks, which some experts say may still be a decade away. Planners are examining exactly what an electric-truck stop would require: Big trucks need big batteries and very large charging infrastructure.

Utility companies in California, Oregon and Washington are underwriting a study that will examine how to provide electric charging and hydrogen fueling along the entirety of Interstate 5, with bays for next-generation semi-trucks running on batteries or hydrogen gas.

State regulators recognize that innovation doesn’t always align with government goals and deadlines and are planning for clean technology where feasible. Like everything else, it’s not going to be cheap.

The cost of an electric semi-tractor trailer, $300,000 or more, is more than twice that of a traditional diesel truck. That can be a burden on mom and pop companies, 90 percent of whose fleets contain six or fewer trucks and who operate on relatively tight margins.

“It’s going to be tough,” even with state subsidies, said Chris Shimoda, lobbyist for the California Trucking Association.

Shimoda said his members don’t care what type of fuel the state requires. “Everybody knows this is the direction California is going,” he said. “It’s easy to say we have a goal of eliminating fossil fuels, but as I think everyone would admit, the details of how to get there are important.”

At the Port of Oakland, with freight-train horns blaring in the background, Taylor said by phone that it’s eerie to see—but not hear—his company’s electric big-rig pull into one of the loading bays. “It kind of sneaks up on you,” he said.

The company’s been testing the truck for more than a year, underwritten partly by a state grant, and expects delivery of two more in the fall. Taylor uses the truck to move containers around the port but has yet to put it on the road, echoing the “range anxiety” associated with electric cars. His truck’s battery runs out and needs recharging after 120 miles.

“I guess it can only get better with electrics,” he said. “I’m not sure how it’s all going to work, but it’s happening.”
