In shift to electric bus, It’s China ahead of U.S. 421K to 300
Plodding down DeKalb Avenue in Brooklyn is a bus moving under the power of an eerily quiet motor. It looks newer than most buses on the route, with a vivid digital display facing the driver and doors that part with a futuristic pneumatic swoosh. Commuters trundling aboard at rush hour don't seem to realize this is one of the few electric buses—300 last year, to be exact—in America.
In China, an electric bus wouldn’t be unusual at all. Out of almost 425,000 e-buses worldwide at the end of last year, some 421,000 were in China. The global e-bus fleet grew about 32% in 2018, according to a BloombergNEF report released Wednesday, with the vast majority hitting the road in China. Europe had only 2,250 electric buses, by BNEF’s count.
China’s municipal e-bus fleet is projected to rise to more than 600,000 by 2025, according to BNEF, at a time when the U.S. is expected to have nearly 5,000. “There’s no industrial policy in the U.S. for e-buses,” said Nick Albanese, a New York-based analyst at BNEF. “So unless the U.S. manages to become a big exporter of e-buses, China will continue to stand apart.”
China takes a typically top-down approach to its manifest destiny of vehicle electrification: establish national mandates, subsidize manufacturers, and nurture policy competition among its cities. At least one U.S. presidential candidate is pushing for all new buses nationally to be zero-emission by 2030, but today the U.S. on a federal level is using none of China’s policy tools. The E.U. will require some new buses to be emissions-free by 2025; climate-conscious California, meanwhile, will require all new buses to be zero-emission starting in 2029. BNEF estimates that 18% of China’s total bus fleet was already electrified at the end of last year.
Why do buses matter? They’re big, and they’re in almost constant use compared to passenger cars—and that means hefty greenhouse-gas emissions. BNEF estimates that 500 barrels of diesel are displaced each dayfor every 1,000 e-buses on the road.
American cities are just starting to tiptoe into the e-bus market. Of the Metropolitan Transportation Agency’s 5,700 municipal buses in New York, just 10 are fully electric now and another 15 are on the way, according to a spokesman. The biggest city in the U.S. has been more successful at incorporating hybrid buses, which number 1,700. The agency’s announcement of its initial e-bus rollout came alongside news that it had also ordered 110 new compressed natural gas buses for use in the Bronx and Brooklyn.
The approach for many U.S. municipalities is to consider e-buses only when existing vehicles reach the end of their useful lives. An average bus lasts about 12 years, according to BNEF’s Albanese, and so there are only about 5,000 new buses added across the U.S. each year.
By 2030 e-buses should be cheaper upfront in most countries, according to BNEF. For now, however, cost can be a deterrent. E-buses are cheaper to maintain than diesel models, but many U.S. transit agencies have separate budgets for acquisition and maintenance. California-based e-bus manufacturer Proterra Inc. is trying to address this issue with a battery-leasing program meant to lower upfront costs and enable transit agencies to tap their maintenance budgets for batteries, just as they would for diesel fuel.
The strongest hope for the U.S. to catch up to China in e-buses comes from its strength in technology. North America is already home to multiple electric-bus manufacturers focused on winning domestic orders. By the time electric buses reach cost competitiveness, these companies could have an edge of their own. The e-bus race won’t be settled on scale alone.
“While Chinese companies get more support, the best electric vehicles have been engineered and manufactured by American companies,” said Ryan Popple, chief executive officer at Proterra and a former executive at Tesla Inc. “I like that matchup.”
So far, China enjoys most of the advantages. It “single-handedly” created the global e-bus market, Albanese said, and its centralized government can implement strong policies with speed. China is also home to some of the world’s biggest battery makers, giving domestic bus manufacturers easy access to the costliest component of electric vehicles.
China in 2009 began prioritizing the electrification of its public-transit system, part of its strategy for dealing with widespread urbanization while reducing fossil-fuel imports. That set in motion a series of comprehensive policies, regulations and subsidies that birthed a new industry. A decade later, the results are tangible: China is by far the world’s single biggest market for electric vehicles of all types, and Shenzhen is the global leader in e-buses, followed by Beijing, Shanghai, and Hangzhou.
These factors have most benefited BYD Co., which evolved from a manufacturer of batteries for brick-size cellphones and digital cameras in the 1990s into a colossus that sells as many as 30,000 electric vehicles or plug-in hybrids every month in China. BYD buses are used in about 300 cities globally, said Chairman Wang Chuanfu in an interview, and the company is aiming to double bus sales in Europe every year for the next three years. BYD’s hometown of Shenzhen alone has about 16,000 e-buses, according to BNEF.
China’s strategy is complete electrification of its bus fleet. “It’s not like the approach taken by other countries, to only buy electric buses as additions,” Wang said.
The newness of China’s cities—without entrenched bureaucracies that may resist change—is also an edge. “You don’t run into incumbent bias when you’re building out a new fleet,” Popple said. Plus, emerging Chinese cities are building transit routes with blank slates, Albanese notes, while manyU.S. transit agencies face the prospect of integrating vehicles with charging requirements into established lines.
In China, with help from government policy, electrified public transport came first. “In the West, it’s quite the opposite. The subsidies are primarily to private vehicles, not public transportation,” said BYD’s Wang. “We propose to governments that they need to learn from China’s example of a staged transition.”
