ISO 16110-1:2007

Overview

ISO 16110-1:2007 sets internationally recognized safety requirements for hydrogen generators using fuel processing technologies, specifically for systems with a hydrogen production capacity of less than 400 m³/h at standard temperature and pressure. These hydrogen generators produce hydrogen-rich streams suitable for downstream devices such as fuel cell power systems or hydrogen storage and delivery solutions. The standard applies to packaged, self-contained, or factory-matched stationary hydrogen generator units designed for indoor and outdoor use in commercial, industrial, light industrial, and residential settings.

Key input fuels covered by ISO 16110-1:2007 include natural gas, various methane-rich gases, oil-derived fuels, alcohols, and gas mixtures containing hydrogen. The primary focus is to ensure that hazards associated with hydrogen generation-such as fire, explosion, and electrical risks-are systematically identified, assessed, and minimized.

Key Topics

• Scope and Applicability

  • Covers hydrogen generators below 400 m³/h capacity.
  • Includes systems using a wide range of fuels such as natural gas, biomass-derived methane, diesel, alcohols (methanol, ethanol), LPG, and synthesis gas.

• Comprehensive Safety Requirements

  • Calls for thorough safety and reliability analysis as per international guidelines.
  • Requires the identification and mitigation of all significant hazards throughout the generator’s operating life.
  • Mandates both design-based and procedural risk reduction strategies.

• Protective Measures

  • Inherently safe design and construction.
  • Implementation of automatic process control systems for safe operation and emergencies.
  • Provisions for fire, explosion, electrical, and pressure hazard prevention.
  • Clear marking, labeling, and technical documentation for safety-critical components.

• System Configuration

  • Detailed requirements for fuel processing, fluid management, thermal management, and electrical systems.
  • Stipulations for safe enclosures (cabinets) and robust frame support.
  • Proper installation, maintenance, and routine testing protocols.

Applications

• Hydrogen Fueling Infrastructure: Ensures commercial or public hydrogen refueling stations operate safely, supporting the growth of clean mobility solutions.
• Industrial Processes: Enables factories and production facilities to generate on-site hydrogen safely for chemical synthesis, heat treatment, or energy applications.
• Power Generation: Supports the deployment of reliable and safe hydrogen supply systems for stationary fuel cell installations in commercial or residential buildings.
• Renewable Energy Integration: Facilitates safe processing of renewable or waste-derived gases into hydrogen, advancing sustainable energy transitions.
