Discussions with distribution system operators, municipal utilities, and other industry stakeholders clearly showed that the transformation of gas distribution networks is no longer a question of the future. It has become a concrete planning challenge. Three key topics, in particular, dominated the conversations.

First, the need for robust scenarios and clear target visions is growing. Network operators require reliable decision-making frameworks to assess investments and risks in an environment shaped by regulatory and technological uncertainty.

Second, the future role of hydrogen and other climate-neutral gases was discussed extensively. These remain important building blocks of a climate-neutral energy system. At the same time, decisions made today must be resilient enough to remain viable under different market and regulatory developments.

Third, the importance of cross-sector planning was repeatedly highlighted. The transformation of electricity, gas, and heating networks can only succeed through coordinated action. Integrated infrastructure strategies are increasingly becoming a key success factor for a cost-effective energy transition.

Another prominent topic of discussion was the long-term future of existing gas infrastructure. While many debates continue to focus on the role of hydrogen and biomethane, another question is gaining importance: Which parts of today’s gas networks will still be needed in the future?

As the heating sector becomes increasingly electrified, customer connections and gas volumes are expected to decline, while much of the network cost base remains unchanged. Against this backdrop, targeted partial decommissioning of gas networks is widely considered unavoidable in many regions. As a result, the development of practical approaches for risk mitigation, as well as the orderly planning and implementation of such measures, is likely to become an even greater focus for the industry in the years ahead.

Conclusion: The key challenge is no longer determining which technology will ultimately prevail. Rather, the crucial question is how existing infrastructure can be transformed in a way that is robust, economically viable, and climate-neutral. In times of significant uncertainty, sound decision-making frameworks and long-term strategic planning are more important than ever.

We would like to thank DVGW and all discussion partners for the open exchange and valuable insights into the current challenges of gas network transformation.
