Mobility with renewable energy

For the integration of renewable energy into the mobility sector there are several options, including electric and hydrogen-powered vehicles as well as biogenic and  synthetic fuels.

So far, these engine concepts could not establish themselves on the market. On the one hand, the technical realization has not reached its maturity phase yet and requires further development. On the other hand, it is challenging to provide evidence of the concepts’ ecological benefits and sustainability. The dilemma of food vs. fuel in the biogenic fuels sector increases the problem's complexity. 

Nevertheless, there's is one major consensus: All those alternative engine concepts have an enormous potential to reduce greenhouse gas emissions as long as the energy supply is based on renewable energy sources. The reasonable combination of sustainable drive systems with Renewable Energies represents a main focus the research field “mobility with renewable energies” at RLI.

RLI conducts theoretical as well as implementation-oriented research projects for the integration of renewable energy technologies into the mobility sector, taking into consideration three main approaches:

    1. Battery electric mobility: propulsion of vehicles using electric energy from renewable energy

    2. Hydrogen-electric mobility: production of hydrogen via electrolysis and renewable energy

    3. Synthetic-methane-gas-based mobility: production of methane gas via electrolysis, renewable energy and methanization

Our work's focus is on the analysis of interdependencies between energy- and mobility systems, in order to identify synergies and optimization potentials. Among other topics RLI has dealt with vehicle fleets, micro smart grids and train stations. 

Fields of Competence

Project Management

Innovative research projects in the field of renewable energies are drivers of the necessary fundamental change in the ways we supply and use energy. As a non-profit research institute we are independent and provide the necessary expertise for designing and acquiring new projects as well as executing and utilizing both publicly and privately funded projects focusing on renewable energy systems.


The collection, measurement, preparation, and processing of data is one of our key competencies. It is of outstanding importance for the following working steps as data serve as input for simulations, analyses, and application. We derive reliable results based on well validated input data. To guarantee that we can generate, validate, process, and structure data on many different ways.


On the basis of our models and data our simulations generate a condensed image of real systems to achieve that complex systems become understandable and can be manageably modeled and analysed.


Simulations and measurements generate comprehensive results which we process, evaluate, and make available by applying a diverse range of analyses. Through our interdisciplinary approach we conduct analyses from different perspectives and consider cross-sectoral relationships. This primarily refers to the interaction of the electricity supply, heat supply and mobility sector.


As a non-profit research institute we guarantee objective and independent support for real-life applications. We bring theoretic insights into applications and reflect practical experience back into our simulations and research projects.
