Welcome to
Reiner Lemoine Institute


We are an independent non-profit research institution working towards a future with 100 % Renewable Energy in our three research units Transformation of Energy Systems, Mobility with Renewable Energy and Off-Grid Systems. For more than 10 years we have conducted applied research to give scientific support to a long-term energy transition.

The institute is supported by the Reiner Lemoine Foundation. Reiner Lemoine was a pioneer in the field of renewable energy. While others were thinking and talking about alternative forms of energy, Reiner Lemoine took the lead and founded, amongst others, the solar companies SOLON and Q-Cells.

Knowledge Sharing


Knowledge Sharing

In addition to our independent scientific work, we also support the transformation of energy systems through individual project commissions and studies for businesses, policy makers, local actors, and civil groups.

RLI Tools

At RLI, we have developed various software tools that we use internally and can make available to third parties.

Open Science

Wherever possible, we follow the principles of open science and try to make the majority of our scientific work accessible. This forms the technical and legal basis for scientific reproducibility and genuine participation in the energy system transformation.

RLI Spin-Off

Localiser RLI GmbH is the first spin-off of Reiner Lemoine Institute, offering solutions for efficient planning of charging points for electric vehicles in every region.
