Ulm in the Spotlight: Climate Protection and Hydrogen Strategy in March 2026

Climate Protection in Ulm: Hydrogen and Gas Grid Transformation in Focus

With the goal of becoming climate-neutral by 2040, the city of Ulm is implementing a wide range of measures that were once again intensively discussed in March 2026. The Climate Protection Advisory Board, led by Mayor Tim von Winning, focused on the future of the region's energy mix during a meeting on March 20, 2026—particularly the use of hydrogen and the transformation strategy of the gas grid. These topics are not only technically challenging but also of great political and economic significance.

Hydrogen – Opportunity or Risk for Ulm?

Hydrogen is regarded in Ulm as a key technology for a climate-friendly energy supply. At the Climate Protection Advisory Board meeting, Mr. Renken from SWU Energy presented the opportunities and risks associated with the use of hydrogen in the region. Special emphasis was placed on the potential to supply the transport and industrial sectors with low-emission energy. At the same time, challenges such as the high costs of hydrogen production, infrastructure issues, and the long-term safety of facilities were also discussed.

SWU Energy is cooperating with the H2-Bridge project, which is developing regional hydrogen solutions. The discussion showed that Ulm is aware that hydrogen will not be a panacea on its own but can play a central role in the future of energy.

Gas Grid Transformation: A Challenge for SWU Netze

Another central topic was the transformation of the gas grid. Mr. Langer from SWU Netze presented the current status of the so-called gas grid transformation concept. The goal is to make the traditional natural gas network suitable in the long term for the injection of green hydrogen and other climate-friendly gases. This requires extensive refurbishments, investments in new technologies, and close cooperation with local stakeholders.

The transformation of the gas grid is a long-term process that requires both technical and financial resources. The discussion in the Climate Protection Advisory Board highlighted the need to set clear priorities to stay on track with climate goals.

Progress Report on the Ulm Climate Protection Strategy 2040

The Climate Protection Advisory Board also summarized the current status of the Ulm Climate Protection Strategy 2040, which was first presented in November 2025. This strategy lays the foundation for a comprehensive transformation toward a climate-neutral city. It includes measures in the areas of mobility, buildings, energy, and waste management. The March 2026 meeting served to review current progress and to inform the advisory board about recent developments.

Mayor Tim von Winning, in his role as chair of the Climate Protection Advisory Board, emphasized that cooperation between politics, business, science, and civil society is essential to achieving the climate goals by 2040. The meeting on March 20, 2026, was another step in this direction.

Outlook: What's Next?

The discussions in March 2026 show that Ulm is on the right track, but also that there are still many challenges ahead. In particular, the transformation of the gas grid and the use of hydrogen require long-term planning and investment. At the same time, it is important to actively involve citizens to make the necessary transformation possible.

In the coming quarter, it is expected that the city of Ulm will begin implementing first concrete projects—whether in the form of hydrogen pilot installations or gas grid refurbishment measures. The role of the Climate Protection Advisory Board remains crucial in advancing and making the climate protection strategy transparent.
