The energy revolution is gaining momentum, and with it, the importance of hydrogen as a climate-neutral energy source is growing. However, wherever hydrogen is produced, stored and used, new risks also arise. A well-designed lightning and surge protection concept is essential, especially in potentially explosive atmospheres (Ex zones), in order to protect people, technology and investments.

Comprehensive protection solutions for every application
As your all-solution provider, DEHN offers customised protection solutions for hydrogen applications along the entire value chain – from electrolysis to storage and pipelines to fuel stations. The concepts comply with IEC standards and take into account external lightning protection as well as earthing, equipotential bonding and surge protection.

Special attention is paid to safe implementation in hazardous areas: high-voltage-resistant, insulated down conductors (HVI systems) enable separation distances to be maintained, while spark-free equipotential bonding bars and combined arresters for energy and information technology specifically prevent ignition sources. This ensures reliable operation of electrolysers, control technology and communication systems.

Products and services from a single source
In addition to surge arresters such as the DEHNventil M2, BLITZDUCTORconnect and DEHNpatch, DEHN also offers comprehensive engineering services: from risk analysis and planning to standard-compliant implementation. Training courses, documentation aids and digital tools such as the configurator for earthing and short-circuiting devices round off our range of services.

Whether it's a new build or a retrofit, DEHN offers operators of hydrogen systems a comprehensive protection concept from a single source. This not only increases operational safety, but also makes an important contribution to a sustainable energy future.
