More than a thousand DTU researchers are working on a solution. They are developing new technologies for production of liquid fuels—Power-to-X—from wind turbines, sun, and biogas, and they are conducting research into how to protect these energy sources from unwanted attacks.
We have asked the researchers some of the hot questions about energy. We have also requested them to give science’s answers to the challenges that we are facing here and now and to provide their suggestions for the energy supply of the future.
Denmark gets more and more of its energy from, for example, wind turbines and solar cells. This is of importance to how security of supply is to be handled, as it is difficult to predict production from these energy sources.
Articles about DTU's energy research
The need for charge points for electric vehicles will rise dramatically in the future
If Denmark is to reach the goal of one million electric vehicles on the roads in 2030, the number of charging stations will have to keep up. DTU has created a calculation tool that enables cities and municipalities to analyze how many charge points they will need in the future.
Timely cleaning of heat exchangers significantly reduces energy consumption
As fouling occurs in heat exchangers at Denmark’s combined district heating plants, their ability to transfer heat deteriorates. New research from DTU can be used to pinpoint the right time to remove fouling and thereby avoid large energy losses and unnecessary use of environmentally harmful chemicals for cleaning.
Solar cells do not have to be black. And they can become part of the house façades of the future
Solar panels with different colours can be integrated in the façades of buildings and become an aesthetically exciting part of the architecture. DTU collaborates with façade contractor HSHansen to document the effect of different-coloured photovoltaic elements.
Danish wastewater treatment plants are some of the most sustainable in the world. Not only do they produce electricity and heat from the wastewater they also extract nutrients from the sludge as a resource. A DTU PhD project helps them assess which technologies are most climate neutral.
Energy islands may become the happy ending to energy crisis
Part of the Government’s plan to make Denmark independent of Russian gas is to speed up the establishment of the energy islands. To provide a happy ending, this requires prioritization of research, writes Professor Jacob Østergaard in a column.
