By participating in the Fluxlicon project, the district of Ludwigsburg wants to make an active contribution to the energy and drive transition and further develop its own energy concept in terms of sector coupling in the long term. As a pilot municipality, the district has received a modular and flexible energy storage system - with batteries that were already in use in electric vehicles.

Using solar power efficiently

The storage system makes it possible to make optimum use of the electricity from the district administration's photovoltaic systems by balancing out fluctuations between generation and consumption. Surplus solar energy is stored and is available later when there is less sunshine. This reduces the load on the electricity grid and ensures a stable and sustainable supply - for example for the growing number of electric vehicles.

The district as a role model for other municipalities

The storage system was delivered on March 15, 2025. It will now be commissioned and the results evaluated. The knowledge gained will be made available to the public as best practice so that other towns and municipalities can benefit from it.

Background

Fluxlicon is a research project funded by the German Federal Ministry for Economic Affairs and Climate Protection and carried out by the Agency for
Renewable Energies e. V. and RWTH Aachen University, among others. In addition to the district of Ludwigsburg, the city of Wolfenbüttel was selected as a pilot municipality.

Hydrogen project H2LB

Common direction for a structured transformation

A cluster of blue, translucent molecules resembling water droplets is depicted against a soft blue background. Some molecules are paired, suggesting interactions, while others float individually, illustrating the dynamic nature of fluids at a microscopic level.

The Ludwigsburg district's "H2LB" project is one of 16 projects funded by the state of Baden-Württemberg as part of the "Regional Hydrogen Concepts" (RWK) program.

The aim of the "H2LB" project is to develop a hydrogen strategy for the district of Ludwigsburg. To this end, local requirements and potential for decentralized hydrogen concepts are being analysed. The hydrogen strategy is intended to answer the question of where and when a hydrogen supply can be expected or where other supply solutions already need to be designed, planned and implemented today.

The "H2LB" project was launched on 15.5.2024 and will run for six months. The Karlsruhe Project Management Agency (PTKA) at the Karlsruhe Institute of Technology (KIT) is in charge of the funding program. The district is implementing the project in close cooperation with Energieagentur Kreis Ludwigsburg LEA e.V., the Institute for Ergonomics and Technology Management at the University of Stuttgart (IAT) and the city of Ludwigsburg. Further regional players will be identified and integrated over the coming months.

Green hydrogen is a key factor for climate protection and a successful energy transition. The prerequisite for a hydrogen economy in Baden-Württemberg is to develop the infrastructure for the production, storage and transportation of hydrogen and hydrogen derivatives. Hydrogen derivatives are chemical compounds that are produced from hydrogen and can be used as energy carriers or chemical base materials. They offer a way of storing, transporting and using hydrogen in a form that is more practical or safer than pure hydrogen.

Solar offensive

The greatest potential for renewable energies in the Ludwigsburg district lies in solar energy. However, only 8 % of this potential has been exploited in photovoltaics to date - so there is a great need for action.

The Ludwigsburg Energy Agency's municipal network "Solar Offensive" is developing suitable measures to promote the expansion and cover the growing interest with knowledgeable specialists.
The district administration's climate protection team is involved both with expansion measures on district-owned buildings and with ideas and funding for district-wide campaigns.

Are you also considering whether your roof or balcony could be suitable for producing electricity with a PV system?

You can find initial information on the Energiegantur website and in the fact sheets - the checklist will prepare you for the energy consultation or the discussion with the solar installation company. And in the "Ökochecker" video from SWR you can find out everything about balcony solar systems in a nutshell.

Are you constructing or planning a building or parking lot with more than 35 parking spaces? Or are you carrying out a fundamental roof renovation on a house? If so, you are obliged to install a photovoltaic system or take appropriate replacement measures. The Baden-Württemberg Ministry of the Environment and Energy has produced a practical guide on the obligation to install photovoltaics, which you can view and download here.
