The safe integration of hydrogen technologies into existing and new infrastructures is crucial for a future with climate-neutral energy. DEHN's protection solutions make an important contribution to the stability and efficiency of hydrogen supply systems. From October 21 to 23, 2025, the leading provider of lightning and surge protection solutions and safety equipment will be showcasing its customised protection concepts for hydrogen applications at the Hydrogen Technology World Expo (Booth 5A30, Hall B5). The focus will be on solutions for hydrogen refuelling stations and power-to-X applications such as electrolysers, which ensure seamless and standard-compliant operation in hazardous areas.
For a safe hydrogen future: DEHN presents protection solutions for Power-to-X
With decades of experience in protecting electrical installations, DEHN provides a comprehensive portfolio for the entire value chain of the hydrogen economy – from production and storage to transport and use. Lightning and surge protection is essential in applications involving hydrogen. Hydrogen is extremely flammable, and even small sparks can cause massive explosions. A well-designed protection concept, including equipotential bonding and an earthing system, protects sensitive electronic systems from damage, fulfils legal safety requirements and prevents system downtime and personal injury. Risks are minimised and investments are protected in the long term. The DEHN products and concepts specially developed for potentially explosive atmospheres, some of which have also been tested for hydrogen applications, comply with the highest safety standards in accordance with DIN EN 62305 and DIN EN 60079.
Holistic protection concept for potentially explosive atmospheres
In hazardous areas (potentially explosive zones), it is crucial that lightning protection systems do not generate any ignition sources. Innovative HVI technology for insulated lightning protection helps to maintain the prescribed separation distance between lightning protection and system components. The PAS EX spark-free equipotential bonding bar safely discharges equalising currents in hazardous areas without sparking - even if lightning current passes through. It is suitable for zones 1/21 and 2/22 in which hydrogen is used. In the event of direct lightning strikes, the DEHNventil M2 combined arrester (Type 1+2+3) with RAC spark gap technology protects installations against lightning currents up to 100 kA and surges. In addition, BLITZDUCTORconnect and DEHNpatch safeguard measuring and control circuits, Ethernet infrastructures and bus and telecommunications interfaces.
In addition, DEHN will be presenting engineering services offered worldwide to support customers in the planning and implementation of standard-compliant protection solutions - from risk analysis and planning earthing to commissioning.
