How does an electric car that absorbs CO2 while working

ZEM is another project from Eindhoven University of Technology, which has already participated in Lightyear 0 and Stella Vita.

Max Verstappen won the Hungarian Grand Prix this weekend, his 8th win out of 13 races this year. He is 80 points ahead of Charles Leclerc with 9 races. Although it should not be abolished, Everything indicates that the Dutchman will be world champion againExtension of his current regime for one more year. But there are other reasons to celebrate the success of its representatives in the automotive world in the Netherlands.

This year, after extensive development, The Lightyear 0 becomes the world’s first production solar-electric car Putting the country on top of sustainable mobility technology. and yet, Other projects born in the land of tulips arewho are fully developed there, and which provide alternative methods of green propulsion. and were the products of a team formed in both Eindhoven University of Technology.

the first was a mobile home called Stella Vitaswhich works thanks to a large surface Solar panels on its roof and two open appendages When detained at destination. group is called Solar Team Eindhoven And it’s made up of some of the people who also had a hand in building the aforementioned Lightyear.

The second project that has been unveiled recently is called ZEM, and involves another car with electric propulsion and solar power capture, but it is also the most neutral of all electric cars in the world. According to the university itself, it not only emits CO2 into the atmosphere, but it is made from materials that produce minimal carbon dioxide in its manufacturing process, and It is able to absorb carbon from the air while working.

The two large air intakes at the front are not cooling an internal combustion engine, but rather an intake for a filter that captures the CO2 as the car rolls down the road.

The ZEM is a monocoque with body panels that have used additive techniques in its construction, in addition to using recycled and reusable plastics, pineapple leather, polycarbonate to replace the glass, and lighting and infotainment. Both are modular, allowing usage. Other products outside the car.

At the motor level, ZEM It has nine 2.3 kWh modular battery packs that power an electric motor of just 22 kW or its 29.5 hp equivalent, and it has a regenerative system that allows those batteries to be partially recharged with electric braking or engine deceleration. This recharging, in addition to the recharge that can be done from an electrical outlet, It also gets additional power from solar panels on the roof and hood.

In addition, being made with recycled and recyclable materials, ZEM's manufacturing process has less impact than standard ones.

But what has attracted ZEM’s most attention is its ability to collect CO2 from the air. It does this through its front grille, which is equipped with a system to directly capture carbon dioxide as the vehicle moves forward. The creators pointed out that thanks to this tool, they can be eliminated Up to 2 kg of CO2 for every 20,600 km traveled at 60 km/h. Although this seems like a small amount, if all the cars in the world had a similar system, the reduction could have been substantial.

This capture is done in a filter that must be changed and washed every 320 km, ideally with sustainable energy, and the CO2 is bottled into tanks, which, in the project’s ecosystem, must be recharging the same electricity. points should be installed.

Like any project at the Eindhoven University of Technology, ZEM has solar panels to capture the photovoltaic energy for its batteries.

The team and members of ZEM will travel to the United States this August to visit universities and companiesShowing his work. The idea is to infect others so that the system can spread faster.

“We want to tickle the industry by showing what’s already possible”, Nikki Oakels, the group’s external relations manager, said. add it “If in one year, 35 students were able to design, develop and build a nearly carbon-neutral car, the opportunities on an industrial scale are enormous.”
