Green Team Twente reveals details on new hydrogen car




The Green Team Twente, consisting of students from the University of Twente, shows Tuesday, April 21 new hydrogen vehicles H2Zero. The car is participating in the Shell Eco Marathon Rotterdam to be held from 21 to 24th May.

Unlike the car last year, the UTmotive , the car looks more like an everyday car. The H 2 Zero is provided with a new type of fuel cell with a higher efficiency. By the control electronics themselves to develop the system efficiency has been increased from 44 percent to 59 percent. The design of the car was presented in November last year. The team hopes the new car again to get a place at the top.

A big challenge was this “car of the future to look like also show car. Alyssa va Duijne team says on the website of the University of Twente, the bar for the shape and aerodynamics was much higher than previous years. To build the car, the team was increased from eleven to 21 students.

The car is in the Urban Concept Challenge with the Eco Marathon. Electrician Jan Lenssen of the Green Team submits to Tweakers matter what challenges it poses for the design:. “With Urban Concept must also be stopped there for a traffic light and then be raised We think this is a bigger challenge than just a car design that is as efficient as possible. The car must also fulfill a number of requirements from the Eco Marathon and has a brake, gas, a normal steering wheel, horn, windscreen, side mirrors, normal lighting and some extras for the race. The big difference with a normal car, the big screen in the dashboard where we also have a separate race mode in stopped so that values ​​can be better maintained. ”

“The race is about the efficiency of the car,” Lenssen explains. “You drive ten rounds on public roads around Ahoy where the average speed 26 miles per hour should be. Because everyone is as economically as possible, you have to be within within a certain time. The range is then extrapolated to much you’d drive converted with a liter of petrol. In our category concerns than to distances over a thousand kilometers. The number of kilometers per kilowatt hour is then converted to liters of petrol. ”

As of this year there is no longer converted to miles per gallon, says Lenssen. Yet in comparison, this car has more than 1,000 kilometers retrieve one virtual liter of petrol. All results of the marathon itself will be in kilometers per kWh. The conversion was always previously out of an energy density of gasoline of 42,900 kilojoules per kilogram. Hydrogen was charged with 119 930 kilojoules per kg. Starting this year will be in kilometers per cubic meter of hydrogen.

The car is 3.5 meters long and 1.20 wide and high. The team consists of 21 students for the first time. Previous years the team always consisted of 11 students. This year there for the first time alongside the students of the University of Twente also a student at Saxion.
