MANIFOLD - Model development and model coupling in the field of actor behaviour in innovation and diffusion networks

The MANIFOLD project aims to enable energy system models, despite their primarily techno-economic focus, to better take into account the results of quantitative and qualitative empirical socio-economic analyses of the behaviour of actors in the context of the energy system transformation and, above all, to do so with less methodological effort.

Project Funding:

Federal Ministry for Economic Affairs and Climate Action (BMWK)

Project Duration:

October 2019 until September 2022

ZIRIUS will carry out qualitative analyses on the emergence of innovations in the heat sector with a focus on actors and different forms of knowledge in the innovation process. The analyses serve the further development and calibration of the SKIN Energy Model, which is developed by the project partner Iqib. The analysis is based on the typical functions developed in the theory of technological innovation systems, which an innovation system must fulfil:

- Knowledge development and diffusion

- Influence on the direction of search

- Entrepreneurial experimentation

- market formation

- legitimation

- resource mobilisation

- Development of positive externalities (Bergek et al. 2008)


Whether and how these functions are fulfilled depends in particular on the interaction of heterogeneous actors and different forms of knowledge generation and knowledge exchange. In addition, the requirements for knowledge and forms of knowledge etc. change in the course of innovation processes.

First of all, actors are identified who are important for the innovation system under consideration and with regard to their fit to the energy system models also used in the project, and who are important in different innovation phases. The data collected through interviews and workshops will complement the data and network analyses carried out by project partner Iqib. In addition, a close exchange with the diffusion analyses to be carried out in the project, which are planned by the project partners ISI, RWTH Aachen and TU Braunschweig, is planned.

The results are to be used to a) specify the agents in the agent-based model, b) identify questions for the model runs and simulations, and c) uncover obstacles in the innovation system and develop possible measures.
