Functional Safety and Industrial Security for use in the hydrogen industry

Hydrogen (H2) is considered the energy source of the future. It will play a key role in the transition to a sustainable power supply. Pilz is contributing to this transition with the focus on hydrogen safety, by optimising the generation of green hydrogen from renewable energy sources such as wind power or photovoltaics as well as the safe distribution to users via safety-related solutions. Our core competence in the field of Functional Safety and automation ensures a green and safe future.

Hydrogen H2 – Safe and Secure

Hydrogen is a highly flammable gas. For safe production, handling and use, you need safety systems to reliably prevent and manage hazardous situations when dealing with hydrogen.

Pilz offers a variety of solutions for controlling and monitoring safety functions. We can help you increase the safety of your hydrogen – with certified components, reliable sensor technology and comprehensive services throughout the whole lifecycle.

Pilz can support you with the challenges of hydrogen safety

Our safety systems for hydrogen safety:

Safe small controller PNOZmulti 2 controls and monitors the required safety functions in your hydrogen application
Automation system PSS 4000 is used on large plants in the hydrogen industry in the field of Functional Safety - when a large number of inputs and outputs are required
PNOZmulti 2 and PSS 4000 are certified up to SIL 3 of EN IEC 61511 and satisfy the requirement of EN IEC 61508

Our safety solutions for Industrial Security:

With the increasing digital networking of plants and systems in hydrogen production, storage and hydrogen applications in industry, the topic of Industrial Security must absolutely be taken into consideration in order to protect sensitive plant data. Here too, Pilz offers tried and tested solutions for dealing with threats.

I.A.M. (Identification and Access Management) provides support from user authentication to operating mode selection, or data and network security to access management.
protects the control network from manipulation through unauthorised access. The online connection is established via a VPN connection with role-based user management (developed in accordance with IEC 62443)

New VDMA standard sheets for standardisation of H2 plants

The German Engineering Federation (VDMA), Europe's largest mechanical engineering association, is continuing to drive forward standardisation in the hydrogen sector of the future. Several new drafts of VDMA standard sheets are intended to clarify and harmonise key technical and regulatory requirements for hydrogen plants.

Safe dynamic process value monitoring with the small controller PNOZmulti 2

With its analogue input module PNOZ m EF 4AI, the safe small controller PNOZmulti 2 ensures precise recording of important process values, from pressure and temperature to flow rate. Thanks to the high accuracy of 1 % per input, maximum safety is guaranteed even in sensitive areas such as hydrogen technology. You can detect discrepancies at an early stage and keep your processes reliably in the green zone.
