H2 quality requirements

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

Glossary:

H2 quality requirements are 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?
Yes
Type of Barrier
Structural barriers, Regulatory gap
Assessment Severity
2

Questions:

Question 1 What is the basis for the billing of Hydrogen and Hydrogen Natural Gas Mixtures? Only the energy flow (kWh) or are other properties involved?
Energy flow is the only billing basis.
Question 3 Are there other hydrogen quality related legal and administrative requirements to allow the injection of hydrogen in the grid?
TSO monitors the quality of the gas entering the grid. The gas must be acceptable for all the clients. TSO has set a limit of max 1 % of hydrogen in natural gas.
Question 4 How is the responsibility in your country organized with regard to the measurement and other injection related quality requirements? Is this the responsibility of the producer, the TSO or a third party?
TSO monitors the quality of the gas entering the grid.
Describe the comparable technology and its relevance with regard to hydrogen
Injection of biogas to natural gas grid

National legislation:

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.
  • Regulation 715/2009 on conditions for access to the natural gas transmission networks
    Regulation 715/2009 sets non-discriminatory rules for access conditions to (a) natural gas transmission systems; (b) LNG facilities and storage facilities taking into account the special characteristics of national and regional markets

    To achieve this, it sets harmonised principles for tariffs, or the methodologies underlying their calculation, for access to the network, but not to storage facilities, the establishment of third-party access services and harmonised principles for capacity-allocation and congestion-management, the determination of transparency requirements, balancing rules and imbalance charges, and the facilitation of capacity trading.
  • Regulation (EC) No 713/2009 of the European Parliament and of the Council of 13 July 2009 establishing an Agency for the Cooperation of Energy Regulators
    Article 1 Project matter and scope
    This regulation aims at:
    (a) setting non–discriminatory rules for access conditions to natural gas transmission systems taking into account the special characteristics of national and regional markets with a view to ensuring the proper functioning of the internal market in gas;

    Article 8 “Tasks as regards terms and conditions for access to and operational security of cross border infrastructure
  • Commission Regulation (EU) 2015/703 of 30 April 2015 establishing a network code on interoperability and data exchange rules
    The network code on interoperability aligns the complex technical procedures used by network operators within the EU, and possibly with network operators in the Energy Community and other countries neighbouring the EU.Article 7, Measurement principles for gas quantity and quality. In addition to interconnection points, Article 17 shall apply to other points on transmission network where the gas quality is measured. Article 18 shall apply to transmission systems. This Regulation may also apply at entry points from and exit points to third countries, subject to the decision of the national authorities.
