The sporty all-electric car from the Netherlands resembles a BMW car, but is unique: It captures more carbon than it emits. "Our end goal is to create a more sustainable future," said Jens Lahaije, finance manager for TU/ecomotive, the Eindhoven University of Technology student team that created the car. Called ZEM, for zero emission mobility, the two-seater houses a Cleantron lithium-ion battery (锂电池) pack, and most of its parts are 3D-printed from recycled plastics, Lahaije said. The target is to minimize carbon dioxide emitted during the car's full lifespan, from manufacturing to recycling, he added.
Battery electric vehicles emit virtually no CO2 during operation compared with combustion-engine (燃烧式发动机) vehicles, but battery cell production can create so much pollution that it can take EVs tens of thousands of miles to achieve "carbon parity (相同)" with comparable fossil-fueled models.
"Direct air capture is a fairly new method of cleaning the air by capturing CO2 into a filter (过滤器). We have made use of this innovative technology and implemented this in our car. The idea is very simple: while driving, air will move through our self-designed filters and the CO2 will be captured and stored." ZEM uses two filters that can capture up to 2 kilograms (4.41 lb) of CO2 over 20,000 miles of driving, the Eindhoven team estimated. They imagine a future when filters can be emptied at charging stations, based on the fact that there are a nationwide charging infrastructure, which includes residential, commercial and public chargers across the country installed by the Energy Department, automakers and private businesses.
The students are showing their vehicle on a US promotional tour to universities and companies from the East Coast to Silicon Valley, hoping to attract more financial support.
It is hard to tell where the future will take the electric vehicles, but it is clear that they hold a lot of potential for creating a more sustainable future. In the end, only time will tell what road electric vehicles will take in the future.
