H2 quality requirements

This LAP is concerned with the gas quality issues for hydrogen injection and transport in the low pressure DSO local gas grid, including gas quality monitoring and metering in relation to payment terms and responsibilities for monitoring and metering


Requirements related to the quality of hydrogen (in relation to the composition of the gas(blend) as well as its physical property
Hydrogen quality is a term to describe the gas quality for use in the natural gas grid.
Is it a barrier?
Assessment Severity
There is really no application, not now, nor in the foreseeable future, for injection of hydrogen at distribution level of gas grids. This is because there is only one local/regional gas grid in Rogaland, and the vast amount of renewable energy in Norway makes it unlikely that gas grids will be developed in future. For these reasons, there is no defined LAP and no barrier in this area

EU Legislation:

  • Directive 2009/73/EC concerning common rules for the internal market in natural gas
    Directive 2009/73/EC establishes common rules for the transmission, distribution, supply and storage of natural gas.

    Its provisions and obligations apply to Hydrogen Gas by virtue of Article 1 (2), which states that the rules established by this Directive for natural gas, including LNG, shall also apply in a non–discriminatory way to biogas and gas from biomass or other types of gas in so far as such gases can technically and safely be injected into, and transported through, the natural gas system.

    Article 25 establishes the “Tasks of the distribution system operator” which include: ensuring the long-term ability of the system to meet reasonable demands for the distribution of gas […];shall provide any other distribution, transmission, LNG, and/or storage system operator with sufficient information […] as well as to ensure that the system operator does not discriminate between system users or classes of system including, including e.g. when setting rules for the charging of system users, etc

    Article 32 sets the rules on “Third party access”: access to the transmission and distribution system, and LNG facilities shall be based on published tariffs, applicable to all eligible customers, including supply undertakings, and applied objectively and without discrimination between system users.
