With a shift from fossil-based systems of energy production and consumption to renewable energy sources also comes a shift for the transportation. This is also true for pipeline leak detection systems. To guarantee the safe and efficient monitoring of the pipelines, leak detection systems must be adapted to the new requirements coming with the shift.
The paper describes how existing leak detection systems can be adapted to handle the requirements of energy transition applications and work with best possible 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 and special features of these applications for leak detection are described. The paper also includes real examples of model based leak detection systems that have already been implemented in energy transition applications, how a long term efficient performance was guaranteed and how challenges were overcome.
