Energy System 2050 – A Contribution of the Research Field Energy

“Energy System 2050” is a joint initiative of the research field energy of the Helmholtz Association. Running until 2019, it is aiming at improving the concrete understanding of energy systems and at developing technological solutions for use by politics and industry.

Sustainability analysis of energy storage systems for the energy system transformation

Battery storage systems represent an essential flexibilization option for the success of the German energy system transformation. These technologies must meet a wide variety of requirements, such as high technological performance, low costs and environmental impacts. Scientists at the Karlsruhe Institute of Technology (KIT) have analyzed the sustainability of various batteries for stationary applications, taking into account stakeholder interests. In line of this, a publication on the CO2 footprint and life cycle costs of different batteries was published. The article was voted one of the best articles of 2017 by the journal "Energy Technology." more


Sun, wind and power trading

The use of renewables like the sun and wind can cause fluctuations in power grids. But what impact do these fluctuations have on the security of power supply? To answer this question, scientists from Jülich and Göttingen worked together with colleagues in London and Tokyo to analyse different types of fluctuations in several power grids in Europe, Japan, and the USA - and came to surprising conclusions. Their study was published in January 2018 in the peer-reviewed journal Nature Energy. more

 


Dirk Witthaut appointed at the University of Cologne

Dirk Witthaut, co-coordinator of the research topic storage and grids, has been appointed as junior professor for the physics of complex supply networks at the University of Cologne. He has been jointly appointed with the Forschungszentrum Jülich, where he is heading an independent Helmholtz Young Investigator's group at the Institute of Energy and Climate Research. Dirk Witthaut is working at the interface of engineering, theoretical physics and applied mathematics. A main goal of his research group is the development of new methods and mathematical tools for the analysis and optimization of future power grids. This combination of basic and applied research is now further strengthened by the joint appointment.
