Still waiting to buy a hydrogen car?

Green Team Twente makes a move in the right direction

Everyone knows the battery-electric Tesla’s. In 2012, they introduced their model S which gave the sales of electric vehicles a boost in countries like the US, China, UK, Norway and the Netherlands. During the same year, Green Team Twente was founded at the University of Twente, the Netherlands. They did a great job by building a magnificent hydrogen car, which won the first place at the European Championship for ultra-efficient hydrogen cars.

Since then, the battle of future mobility has begun. Will the battery electric car like the Model S win or will it be a hydrogen electric vehicle? At the moment hydrogen cars are at the beginning of their growth stage, but consumers are not really aware of their existence and car companies are waiting for a proper hydrogen refueling infrastructure. Therefore, the market for hydrogen cars is currently less developed than the battery electric market, but both have the same potential. Hydrogen vehicles are known for their longer range and shorter refueling times compared to battery electric cars. This potential has to be made reality within the upcoming years.

During my studies MSc Industrial Engineering and Management at the University of Twente I wanted to do something which creates an impact. At the Green Team Twente we are working on building the most efficient hydrogen car. The estimations for this year are high, but realistic. With a fuel efficiency of 1L to 1000 km (gasoline equivalent) we belong to one of the top teams in the world.

Number 1 in Europe

As mentioned at the beginning, the first year was a great success. With a fuel efficiency of 727 km/l we became the number one of Europe. During the following years, the track became a lot harder and even some hills were added. It is a very realistic simulation of normal day to day driving, but it makes it very tricky to drive as efficient as possible. Last year, June 2016, we were back in business with a third place.

The Green Team-ers

We are working with the most motivated people you will find at the University of Twente. We create impact and are able to push ourselves to the limit. We have a great diversity with 19 students from different studies and different nationalities. They are working on a full-time or part-time base for one year. A very appealing setting for this student team is that team members can integrate parts of their study, so they really can become a specialist in their discipline.

The team consist of car enthusiasts, so a lot of inspiration is fetched through Formula One teams. They know how to build a car and process it in a professional way. For example, we like the way they express their partners on the car or how they handle data acquisition. In the future it would be great to learn more from those teams.


Partners are the key

In order to build one of the most fuel efficient cars, we depend on good relations with our partners. Every new team meets existing partners and are looking for new ones to improve our network. Since 2014, Bronkhorst is one of our partners. By supplying us with their flow meters, we are able know the exact flow of hydrogen and air in our fuel cell. Which is extremely important during the race, in order to optimize our driving strategy.

Our powertrain consists of a PEM fuel cell with super capacitors that work like a buffer. The fuel cell generates a constant amount of power whereby the capacitors are used to release or capture extra energy during acceleration or braking. While driving we can control the amount of energy produced by the fuel cell by adjusting the flow of air. Of course, we want to finish with the least amount of hydrogen used, so knowing the exact flow of air will benefit us to make the car as efficient as possible. For now, we, the Green Team Twente and Bronkhorst, are going to continue to realize more awareness and popularity of hydroen powered cars by pushing the current technology to the limits of efficiency.
