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.
What are the legal and administrative requirements and responsibilities with regard to real-time Measurement Technologies for the monitoring and billing of Hydrogen Natural-Gas Mixtures? Do they differ from the requirements for natural gas?

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.
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 DSO or a third party?
	TSO monitors the quality of the gas entering the grid.

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. Other relevant provisions for the injection of hydrogen at transmission level are contained in Article 42 “Regulatory regime for cross–border issues” and Article 43 “Compliance with the guidelines" Article 8 “Technical rules”, Article 25 “Tasks of a distribution system operator”; Article 28 “Closed distribution systems” Article 41 “Duties and powers of the regulatory authorities” Article 35 “Refusal of access”; Article 8 “Technical rules”; ”
