The history of our cars

Green Team Twente started in the academic year 2011-2012 as an initiative of W.S.G. Isaac Newton, the study of mechanical engineering at the University of Twente. They started the project to show the world that hydrogen is a viable alternative to fossil fuels. In the following years, each year a new team was formed with members from different studies and not only mechanical engineers.

The new teams developed through the years and new aspects were added. Not only did they focus on the car, but also educated people about hydrogen. All the teams and the development of the car through the years will be shown.

2022-2023 Apollo GDO

A new focus: the Formula Student Competition. This was the new goal for our team this year. The Formula Student (FS) is an engineering design competition and can be seen as the Formula 1 competition for students. 

During the FS this year, we were the first team to join with a hydrogen race car. Of course GTT has a lot of knowledge in building a hydrogen car, but a race car was completely new, which meant we had to do new and exciting things we didn’t have a lot of experience with.

Luckily our previous team already built a foundation for us to work with. Together we faced this new challenge head on and this is definitely reflected in our results. In just one year we built a new Formula Student Hydrogen race car (with all the electronic components working & driving) and a fully working hydrogen system designed for this race car! We had the chance to show and explain our system during FSNL and FSG where we not only experienced a lot of interest from the people working at FSNL & FSG, but also from all the other participating student teams.

With this year flying by and too little time to integrate our hydrogen system in our car (named Apollo GDO), it is the task of the new team to further develop our car. We fully believe that they will succeed in this mission. We had a great year filled with experiences that we will never forget!

Changing our game

At this point, Green Team Twente had been participating in Shell Eco Marathon (SEM) for over 10 years! We had put several first titles on our name and took victory with the title of World Champion in 2019. Participating that long, means that at some point, the greatest milestones are already achieved, and innovation is almost impossible. However, Green Team Twente is all about innovation. Therefore, we decided to change our focus. We started participating in Formula Student Races (FS), which is THE racing environment where innovations are born.

Where SEM is about building the most efficient car, FS is about building the most powerful car. Therefore, Green Team Twente had to start all over in terms of knowledge about building a hydrogen car to be able to build it towards power. From this point on, Green Team Twente is striving to be pioneer in Formula Student, and more importantly, striving for hydrogen technology innovations within, and outside the scope of Formula Student.

It was decided to take part in both the SEM and the FS to ensure a smooth transition between these competitions. The SEM race took place at the end of June, at the TT circuit of Assen. It was a chaotic week, with a lot of unforeseen challenges to overcome, especially during the technical inspection phase. It was very close, but eventually, we passed the Technical Inspection in time.

We improved the efficiency of the car during the different race attempts that followed after the Technical Inspection. We reached second place with a final efficiency of 305 km per m3! We were very happy with this result because it was already unlikely that we’d be able to set a valid attempt due to the big fuel cell problems we experienced two months before the race.

With the last SEM race now officially finished it was time to focus on the new future of Green Team Twente; the Formula Student competition. This new future started for us at a known place; Formula Student Netherlands also took place at the TT circuit of Assen. We had been working full-time on our new race car for the whole year, but creating a driving car in one year was not doable. However, we were present with a completely new body, all big powertrain components, and chassis, suspension and wheels being done. This resulted in a lot of interest from the other FS teams. The goal of the event was to convince these teams to create a hydrogen car as well, such that it was possible to start this competition. A few teams were interested to consider changing to hydrogen, one team even said that they are definitely going to change. Besides, the Formula Student competition said that they are now looking into officially adding a hydrogen class to the competition. This was a big win for the team!

This team expanded on the work of the team before it. A new fuel cell was put in the car, and the electronic systems were upgraded and the latest software was installed. Mechanical components were optimised in order to make them simpler and lighter. This weight loss, in combination with the improvement of the overall electronics in the car, made it even more efficient than it was at the beginning of the year.

Another aspect the team made steps in is education; they gave online lectures to schools, and, for the first time, an exhibit about Green Team was held at the Museumfabriek. Next to that, a documentary about hydrogen was made.

The Shell Eco-Marathon was cancelled due to Covid-19, which is why the team joined forces with two other Dutch hydrogen student teams, Hydromotive and Eco-Runner Delft, to organise their own event: The “Hydrogen Efficiency Challenge”, presented by Allard Kalff. Despite setbacks due to a malfunctioning fuel cell, the team put in an attempt and finished second with an achieved efficiency of 2500 km/kg of hydrogen. Together with the other teams, they proudly look back on a great event to close off the year.
It was a unique year with ups and downs, and even though the team faced challenges, they managed to get the car driving in time to race it, at their own event, against the best hydrogen efficiency teams in the Netherlands. In the end, they can look back on a year that was more than worthwhile, also thanks to the continued support of the partners during the pandemic.

2018-2019 Aurora 2

We became World Champion! With not one, not two, but three trophies, our team came back to Enschede after the Shell Eco-Marathon of 2019. In our year, we focussed on making the car more reliable and improving it wherever possible. We took the lessons from team 18 and made the car our own.

By redesigning the drivetrain and electrical components, but also by significantly improving the cooling system of the fuel cell and the strategy for the race itself, we managed to bring the car to world level. Apart from this, we devised an extensive communication strategy to bring hydrogen and our team to the next level. We set up a project with the University of Twente to put a sustainable tiny house community on campus.

Furthermore, we put more emphasis on education by making educational videos and going to schools and events to give guest lectures. By also competing in the Challenger Event, we gave ourselves the chance to work out any kinks in the cable and to get the first official test round before the real Shell Eco-Marathon. 

And this paid off, as we went to the Shell Eco-Marathon with not only a great car but also with great confidence. This wasn’t misplaced, as we not only won the Shell Eco-Marathon Europe, but also the Driver’s World Championship and Communications Award. We couldn’t have been happier with these results and we will look back at this year with much pride.

2017-2018 Aurora 1

Our 2018 team rotation was marked with two big changes. For almost six years with our red color and the burning wheel logo, it was time to say goodbye to years of confusion, misfitted branding, and the H2Infinity.
Both, our communications team and our technical team took on their own challenge: creating and designing a new brand identity and building a new car. It took us nine months from mission statement to a new brand, and almost 11 months from a design scratch to a brand new Green Team Twente car.

Our new logo was revealed in an epic brand launch in March 2018. Complementing to our name we wear the true green color and have a clear logo communicating hydrogen our main power source.

Our green beauty Aurora One was revealed to the public in April 2018. With a sleek, aerodynamic car design, we were ready set new records at the Shell Eco-Marathon 2018. And while testing days in Twente went very well, technical disturbance during the marathon hindered us to set a valid attempt at the competition in the end.

Nevertheless, our great marketing execution won us the communications award so that we still traveled home with a cup. Now, playing the ball to the next team, we are very excited to see the improvements and results from the team rotation of 2019.

2016-2017 H2 Infinity

This year’s team focused their work on reliability and continuous improvement. The expectations were high for the second edition in London of the Shell Eco-marathon, because of the chassis based on the former H2Zero and some other new systems. We created a special PCB design on the body to give a car a nice face. This design stands for innovation and we brought it with a fully integrated dashboard on the steering wheel, a new ultra-efficient gearbox, an electronically managed clutch system and a real-time data system in the cloud.

At the day of the Shell Eco-marathon, things were running smooth. We passed as the first hydrogen team the technical inspection. This was a good start, because this results in more test runs. Unfortunately we needed the extra time because the optimal set up was not reached, yet. After three days hard work, it all came to the second race day. Everything had to run perfectly in order to set an ultra-efficient stint and we managed to do so! We were the best in our class and that resulted in winning the first place and having the most fuel efficient hydrogen car of Europe in 2017!

Another revision of the body has been made to make it stiffer and lighter. Also, the powertrain was adjusted this year so that just one wheel was driven instead of two, in this way a more efficient transmission can be achieved. In addition, this was the first team that participated at EduEco.

The purpose of this race was to practice driving strategy and to test the car well for the Eco-Marathon, which was this year for the first time in London. The ambition of this team was to create a good foundation of a car where the next team could continue to optimize this. And finally, a result was obtained: third place with a record of 890 km/l.

This year the largest team was active to design and making a completely new car. With many different disciplines, they have worked hard to create a beautiful car. This year, after a lot of research a whole new hydrogen system was introduced, with as a pièce de résistance: a custom-made fuel cell system, wherein the cells of the German ZBT are used.

In addition, a new body has been designed such that the aerodynamics of the body is better. A long backside with a very small slope is used to make sure the air detaches as late as possible. Also this year no result was put down at the Eco-Marathon despite the efforts, but the team did win first place in the battery-electric category at the Challenger event in Rockingham, England.

This year, in addition to mechanical and electrical engineers, a chemical engineer and a health science student became part of the team. The aim was to expand the borders of the team even further to include almost all studies of the UT. It must be a university-wide team that offers students the opportunity to participate in an innovative, sustainable project in which they can put their newly gained knowledge into practice. This year’s work includes carbon rims to minimize the weight of the car, but despite that, no result was put down.

The following year it was decided by the association that this success story should be continued. After recruitment in September 2012, the teams also consisted of the studies of Electrical Engineering and Advanced Technology. This multidisciplinary approach enabled us to innovate on multiple fronts, with the aim of a more fuel-efficient car!

The entire electronic system is re-created that year and equipped with a CAN bus, which means that all the microcontrollers of the various components are on the same network and thus communicate with each other. This made it possible to also to start collecting data. The same body is rebuilt but this year with a lighter rib structure. The team improved the result for the previous year with a result of around 800 km/l, which led to third place.
