Gas-powered vehicles to tackle PM2.5

GAS-POWERED trucks, buses and taxis could pave the way for reducing PM2.5 pollutants, city authorities said yesterday.

Shanghai will test dimethyl ether — a non-toxic, cleaner-burning hydrocarbon gas that generates neither sulfur nor nitrogen particles — on trucks, the Shanghai Economy and Informatization Commission said yesterday.

Dimethyl ether will also be tested in about 50 taxis in Minhang District and some bus lines, the commission said.

“The commission will coordinate with other authorities to build the infrastructure such as gas stations,” the commission told the local legislative body.

Exhaust emissions are the biggest source of PM2.5 pollutants — small particles particularly dangerous as they can lodge in the respiratory system.

Vehicles produce 25 percent of PM2.5 in the city’s air, according to the Shanghai Environmental Protection Bureau.

“It’s time to expand new energy, which would help better control PM2.5 pollution,” said Ding Kuiling, director of the Shanghai Institute of Organic Chemistry and a lawmaker.

Dimethyl ether costs 3,000 yuan (US$482) a ton, cheaper than gasoline, he added.
