Students at DMT

DMT works together with universities all over the world, in the fields of technique and international marketing. DMT has around 8 students during every half a year, from all kinds of nationalities. They all work on an individual project, together with our department Research and Development. We offer the students housing and a student fee. But most of all, we offer them to be part of a fast growing company who wants to be leading in innovation for clean solutions.

At the first intake we discussed the subject for my research. DMT-ET wants to expend their business to Asia and starting in Malaysia. My supervisor told me that he wanted me to join him in a ”fact finding mission” to Malaysia. It was an amazing start of my internship and gave me a lot of insights and contacts to start the research. After a few months of research I had written my bachelor thesis and presented it to the director and supervisor. After my internship they asked me to work for another three months at DMT-ET. DMT is still developing the Malaysian market but they took my report seriously and used it to expand DMT-ET in Asia. For me it was a great ten months at DMT-ET. I learned a lot from great people in the office and they gave me the freedom, responsibility and trust to deliver the reports on my own way. That’s something I really appreciate. I can only say one more thing: if you get the chance to apply for a marketing or other internship JUST DO IT, you will never regret it! Martijn Breen

It led me to working on biogas upgrading, a field in which I had basically no knowledge. My mission was to reduce the capital expenditure of the Carborex®MS, an installation treating and enriching the biogas in methane. Thereby I made simulations on specific software and I collaborated in the development of Matlab model. I also studied the market, its potential and the different competitors. From a personal point of view, this internship encourages me to keep working in the field of biogas, whatever the field, production or biogas treatment. I really appreciated my work by its diversity, not only restricted to a scientific part. I learnt a lot about the market, the technologies but I also learnt to keep a critical eye on the information and results that I found, especially by simulations. It was a formidable human experience, professionally and personally enriching. All the interns work in the same office, and if you are lucky, you could live in Rohel, Friesland (NL) with others interns. The work atmosphere was really motivating, friendly and people very helpful. My only advice: apply to do your internship here!!! Gaël Dupré.

However, I can now assure that this was one of the best experiences I’ve ever had! The project I worked on was based on finding the most promising markets for hydrogen for the upcoming years, particularly in Europe, as well as sustainable technologies available to produce it. The amount of knowledge I acquired during my time at DMT was unmeasurable, since I was not only supported by the R&D department, but also by the Marketing team, as well as from every other worker at the company. I had three supervisors during my internship period, who were closely guiding me and helping me find the tools to solve any problem or doubt I could have throughout the way. Furthermore, having the opportunity of attending a very important congress in Sweden focused on advanced biofuels and their latest uses in the transport sector, as well as the opening ceremony of the first hydrogen refueling station in Stockholm, gave me the chance to obtain even more information directly from experts, which helped me a lot with the development of my project. I would definitely recommend all students from any country of the world who are interested on having a one-of- a-kind internship experience abroad to choose DMT! I guarantee that you won’t regret it, since you’ll have the opportunity to spend time and share knowledge and experiences with the best kind of people you’ll ever meet!
