Deutsche Post DHL's electric StreetScooters reduce noise and emissions... but what about particulates? A new particulate filter has been developed that makes the StreetScooter the world's first emission neutral vehicle.
Electric vehicles release particulates into the atmosphere due to tyre, brake, and road abrasion, so they're not truly emission-free. German company MANN+HUMMEL has developed a fine dust particulate filter to solve that problem.
The filters will initially be fitted to five StreetScooter test vehicles operating in five German city centres. These vehicles will be completely emission neutral, emitting no carbon dioxide or nitrogen oxide, making no engine noise, and producing no particulates.
The fine dust particulate filter is equipped with an active filter system, meaning they work even when the vehicle is at a standstill. The filter is installed underneath the vehicle, meaning there is no reduction in loading space and the filter is located where the highest concentration of particulates is to be found.
According to estimates from the World Health Organization (WHO), every year roughly 47,000 people in Germany die from the effects of particulates.
With more European cities placing bans or restrictions on vehicles, especially in city centres, a technological solution to the problem or airborne particulates could be an important step towards improving air quality.
