1.3 Scope

The IPG provides a structured analysis of known documents relevant for permitting hydrogen and fuel cell systems in Europe, and documents best practice for the installation of different generic types of hydrogen and fuel cell systems. It also provides guidance on issues not properly dealt with in existing documents, and, therefore, provides the basis for harmonised permitting guidance. The IPG takes account of issues such as the installation environment, country and jurisdiction, as well as taking full account of the already established permitting requirements for natural gas appliances.

The IPG applies to stationary systems fuelled by hydrogen, incorporating fuel cell devices with net electrical output of up to 10kWel (small according to IEC 62282.3.3:2007 [1]), and with total power outputs of the order of 50kW (combined heat + electrical) suitable for small back up power supplies, residential heating, combined heat-power (CHP), and small storage systems.

Many of the guidelines appropriate for these small systems will also apply to systems up to 100 kWel which will serve small communities or groups of households.
