Fraunhofer Cluster of Excellence Integrated Energy Systems CINES

Standorte der beteiligten Institute des Fraunhofer Cluster of Excellence Integrated Energy Systems CINES
Participating core institutes (Fraunhofer IEE, IEG, ISE, ISI and IWES) and associated institutes (Fraunhofer IBP, ICT, IOSB-AST, SIT and UMSICHT)

The Fraunhofer research cluster Integrated Energy Systems CINES addresses the central technological and economic challenges of the energy transition. The aim is the system and market integration of high shares of variable renewable energies into the energy system. For this purpose, CINES combines the competencies of the institutes for applied energy research of the Fraunhofer Gesellschaft.

CINES develops solutions for energy system transformation - comprehensive, cross-sector energy system analyses, digital solution models for the digitalisation of new technologies, decisive advances in electrolysis, power electronics and heat, and the successful communication of the energy transition.

The CINES system analysis uses high-resolution simulation and optimisation models to analyse transition paths of the future energy system from the neighbourhood level to global model calculations. Together, the cluster develops the model platform »EFEU – the Energy Future of EUrope« for modelling electricity, gas and heat infrastructures.

CINES provides technology roadmaps that can be used from identifying new business models to proposing new market designs and developing detailed policy instruments. The system analysis offer is thus just as relevant for municipal companies as it is for regulators.

In system integration, essential further developments of optimised, automated operation management and process architectures based on digitalised solution approaches are to be evaluated and demonstrated in a »Future Energy« real laboratory.

The central technical solution for storing volatile renewable energy sources in a bound, storable form of energy is electrolysis. By bringing together various key developments from the participating institutes, a significant reduction in the investment costs for electrolysis plants to a third of today's value is to be achieved.

How can the decarbonisation of the heating networks in Germany be successful? This is the question addressed by the Dimension Heat. The aim of the research network is to develop a transformation strategy for district heating networks based on complex analyses of producers, networks and consumers.

The goal of the power electronics dimension is to transform the electromechanical electrical energy system into a power-electronic one. It researches power electronics equipment and develops it further in order to create the technological prerequisites for the energy transition.

The science communication dimension scientifically investigates aspects of participation and acceptance, as well as socio-economic aspects of the energy transition and climate protection. The cross-institute research group is based at the Fraunhofer Showroom ENIQ in Berlin, where it is involved in the evaluation and development of communication formats.
