Energy technology

The production of energy is one of the world's largest sources of greenhouse gas emissions. To minimise the impact on the climate, oil, coal and gas must be replaced by green energy sources.

Established in 2001, Middelgrunden Wind Farm was the world's largest offshore wind farm at the time. The 20 wind turbines of 2MW each are located in a soft arc in the Øresund off Middelgrundsfortet near Copenhagen, Denmark.

Denmark is one of the countries where renewable energy sources already accounted for around 45% of energy production in 2022.

At DTU, we research how to optimise individual green energy sources such as wind, solar and bioenergy, as well as how the overall energy system can become more efficient through digitalisation and artificial intelligence

DTU's experts in energy and utilities

Jacob Østergaard Professor, Head of Division Department of Wind and Energy Systems Mobile: +45 25130501

Jacob Østergaard is one of the country's leading researchers in future energy systems.

He is an expert in energy islands and has in-depth knowledge of both their potentials and challenges. For more than 15 years, Østergaard has used Bornholm as a living laboratory for energy, and he is a driving force in establishing Bornholm as a centre for offshore wind in the Baltic Sea.

Marie Münster Professor Department of Technology, Management and Economics Mobile: +45 23100284

Marie Münster focuses on sector coupling and renewable energy integration.

Her research revolves around how we can optimise investments in flexible energy systems with production of electricity, heat and Power-to-X and transmission between countries including energy islands.

Henrik Madsen Professor Department of Applied Mathematics and Computer Science Mobile: +45 20834304

Henrik Madsen is an expert in digitalisation in the energy sector.

He works with smart energy systems that connect the individual parts of the energy sector. This requires data and digitalisation to create a digital foundation for a safe, efficient and flexible green energy system.

Denmark currently has 17 established offshore wind farms

Partnerships with companies

A partnership with DTU opens the door to the latest research-based knowledge and direct connections to researchers and students.

DTU aims to deliver research-based knowledge, solutions, consultancy, innovation, and education and learning that actively contribute positively to society.

Green Energy

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.

Collaboration

Students inspire large company with return system

Six DTU students have developed a proposal for a return system for the international company BDR Thermea, which aims to increase circularity in their production of solar collectors.

Get access to world-leading facilities

DTU has a number of unique research facilities that are also available to companies.

Green transportation

Tomorrow’s super battery for electric cars is made of rock

In 10 years, solid-state batteries made from rock silicates will be an environmentally friendly, more efficient and safer alternative to the lithium-ion batteries we use today. Researcher at DTU have patented a new superionic material based on potassium silicate - a mineral that can be extracted from ordinary rocks.

Green transportation

Trucks overtake passenger cars in transition to electricity

New calculations predict that a large proportion of the truck fleet in Denmark will run on electricity within the next ten years. This is due to new taxes and technological developments, but is the industry ready for the transition?

Opinion

100% renewable energy possible with existing technology

There is enough renewable energy, and we have the technology to harvest it. The challenge is how to connect the technologies and distribute the energy when needed. We do not require a new miracle technology that can produce energy for us.
