Teréga and HyLight Conduct Hydrogen-Powered Dirigible Tests for Pipeline Monitoring in France
Teréga and HyLight are testing a helium-inflated dirigible, the HyLighter, for pipeline monitoring in France. This initiative focuses on the 107 km Cazilhac-Narbonne-Claira section and aims to comply with systematic leak detection regulations. Six bimonthly overflights are planned for 2026, pending regulatory approval. The project assesses the dirigible's operational capabilities and environmental benefits, as it operates at low altitudes with reduced noise and zero emissions.

Teréga and HyLight are testing the HyLighter dirigible for pipeline monitoring in France, focusing on the Cazilhac-Narbonne-Claira section. This 107 km initiative aims to fulfill systematic leak detection obligations through six planned bimonthly overflights in 2026, subject to regulatory approval.
The dirigible, which flies at 20-30 meters and is powered by a hydrogen fuel cell, emits no greenhouse gases and significantly reduces noise pollution compared to helicopters. The project aims to evaluate the dirigible's capacity to meet monitoring requirements while minimizing the carbon footprint, potentially informing future network monitoring systems.
