Drones on a methane mission: Lübeck’s gas networks are being checked!

TraveNetz GmbH is preparing for a comprehensive review of the gas pipe network in Lübeck and the surrounding areas in July and August 2025. This measure is part of the European Union's new methane emissions regulation, which aims to increase the frequency of leak tests. This regulation came into force on August 4, 2024 and marks a clear focus on reducing methane emissions, which contribute significantly to global warming. hl-live.de reports on this project, which not only serves security but also climate protection.

TraveNetz will use an innovative laser detection method called TDLAS (Tunable Diode Laser Absorption Spectroscopy) to detect leaks. This method measures methane concentration using light absorption technology and replaces traditional gas detection methods. Drones are also in use that fly at altitudes of 40 to 100 meters at speeds between 10 and 25 km/h. These flying helpers only record methane values ​​and do not take any images or videos, which makes the operation more efficient and environmentally friendly.

Safe gas pipes – a must

The EU Methane Emissions Regulation has two key concerns: safety and reducing emissions. So far, the focus has been primarily on the safety of gas pipes and systems. Now the new regulations require regular measurement and quantification of methane emissions. Around 0.2% of leaks cause 80% of measured emissions, which is why the new approach targets particularly large emitters. Traditional safety tests are being replaced by shortened inspection cycles - the average test cycles are even halved. This ensures a quicker response to leaks, with repairs required within five days and full fixes within 30 days to avoid high emissions.

The inspection by TraveNetz is carried out by experienced specialist companies; all necessary approvals from the aviation authorities are in place. The areas flown include various districts in Mecklenburg-Western Pomerania and Schleswig-Holstein, including the Ostholstein district and the Stormarn district and their surroundings sewerin.com.

A clear plan to reduce emissions

The regulation also requires an annual emissions report for operators of transmission and distribution networks, which must be submitted by August 5, 2025. Part of a company-specific emissions reduction plan, also known as an LDAR program, involves either large leaks that require immediate action or more precise measurements. From February 5, 2026 it is necessary to use specific emission factors for reporting eur-lex.eu.

Another crucial point is that routine venting and flaring is strictly prohibited except in unavoidable cases. Failure to comply with these regulations can result in hefty fines, as state authorities will monitor compliance with the regulation.

Efforts to reduce methane emissions are not only a contribution to energy efficiency, but also an essential measure in the fight against the climate crisis. With its initiative in Lübeck, TraveNetz GmbH is setting an important example for responsible energy supply - this is the key to a more sustainable future.
