With a shift from fossil-based energy production and consumption to renewable sources also comes a shift for the transportation. To guarantee safe and efficient monitoring of pipelines, leak detection systems (LDS) must be adapted to the new requirements.

The article describes how existing LDS can handle the requirements of energy transition applications with optimal performance. This is shown by examples in hydrogen pipeline as well as carbon capture applications. One of the hydrogen examples is a power-to-gas application producing green hydrogen which is then injected into a pipeline. The other application is a supercritical CO2 application where CO2 is removed from natural gas before liquefaction to LNG and then injected into wells.

The different requirements of these applications for leak detection are described. With real examples of model based LDS in energy transition applications it is shown how a long term efficient performance was guaranteed and how challenges were overcome.
