Permission to connect/inject

This LAP concerns the permitting framework and processes (or restrictions) for hydrogen based SNG (via methanation) and injection into the gas grid at TSO or DSO level, along with technical requirements for and oversight of local grid connection facilities

Glossary:

Permission and additional restrictions regarding connection points for SNG from hydrogen compared to natural gas connection points.
Connection: “Network connection” refers to the connection of the hydrogen generating plant to the existing gas supply network, the link to the connection point of the existing gas supply network, the gas pressure control measuring system, the means for increasing the pressure and the verifiable measurement of the hydrogen to be fed.
Injection: Gas grid access (injection) is the system under which market players are allowed to use capacity in a pipeline, network, gas store or other gas facility.
The injection installation is related to the connection facility.

Questions:

Question 1 Is the legislation with regard to injection of Methane (SNG) via methanation from hydrogen the same as for hydrogen? If yes, question 2-9 are the same as for category 7, application 1: injection of hydrogen in the gas grid and do not have to be answered.

Yes The answers for the complete LAP info–sheet are the same as for LAP 7.1.2.

Question 2 What is your legal situation (requirement from legislation and administrative procedures) with regard to international interconnection for the injection in the gas grid with neighbouring countries?

Same as for LAP 7.1.2.

Question 3 Is it possible for a TSO to refuse to feed in hydrogen from neighbouring countries at cross-border interconnection points? a - If yes, under which conditions?

a - Same as for LAP 7.1.2

Question 3 Is it possible for a TSO to refuse to feed in hydrogen from neighbouring countries at cross-border interconnection points? b - Can you have a differentiated treatment (i.e.: applying a more stringent threshold than the one applying under your national law?

b - Same as for LAP 7.1.2

Question 4 What is your legal situation (requirement form legislation and administrative procedures) with regard to a national connection for the injection in the gas grid? Is there a difference if injection takes place in an isolated (regional) network without international interconnections?

Same as for LAP 7.1.2

Question 5 Connection to the gas grid of hydrogen producing facility a - What are the requirements for connection of the methanation plants which primarily use renewable energies to the gas supply network: i. Is TSO/DSO obliged to connect the facilities; can TSO/DSO deny the connection and under which conditions? ii. Are there requirements for TSO/DSO to ensure the availability of connection? iii. Which are the requirements for facility operator/ SNG from hydrogen supplier?

a - i. – Same as for LAP 7.1.2 ii. – Same as for LAP 7.1.2 iii. – Same as for LAP 7.1.2

Question 5 Connection to the gas grid of hydrogen producing facility b - Is required to conclude a connection agreement and if yes, what are the requirements for conclusion of a gas grid connection agreement: i. Connection assessment by the TSO/DSO ii. Assessment of grid compatibility by TSO/DSO iii. How much time does it take to conclude a connection agreement

b - i. – Same as for LAP 7.1.2 ii. – Same as for LAP 7.1.2 iii. – Same as for LAP 7.1.2

Question 6 Grid access (injection into grid) Is it required to conclude a feed-in agreement (grid access contract) between DSO/TSO and SNG from hydrogen supplier? a) Is DSO/TSO obliged to feed-in the H2; can DSO/TSO deny the injection and under which conditions? b) Are there requirements for DSO/TSO to ensure a minimum feed- in capacity? c) Are there requirements (technical) for the supplier of H2 (or for the supplied H2)?

Same as for LAP 7.1.2

Question 6 Grid access (injection into grid) Is it required to conclude a feed-in agreement (grid access contract) between DSO/TSO and SNG from hydrogen supplier? a - Is DSO/TSO obliged to feed-in the H2; can DSO/TSO deny the injection and under which conditions?

a - Same as for LAP 7.1.2

Question 6 Grid access (injection into grid) Is it required to conclude a feed-in agreement (grid access contract) between DSO/TSO and SNG from hydrogen supplier? b - Are there requirements for DSO/TSO to ensure a minimum feed- in capacity?

b - Same as for LAP 7.1.2

Question 6 Grid access (injection into grid) Is it required to conclude a feed-in agreement (grid access contract) between DSO/TSO and SNG from hydrogen supplier? c - Are there requirements (technical) for the supplier of H2 (or for the supplied H2)?

c - Same as for LAP 7.1.2

Question 7a - Will you treat a connection for SNG from hydrogen injection in the same way as a regular connection for natural gas injection? Or are there other legal/administrative responsibilities/requirements for you as TSO/DSO but also for the supplier with regard to the permission to connect/inject Hydrogen? If yes: please name them.

a - Same as for LAP 7.1.2

Question 7b - Are there other requirements for the injection of SNG from hydrogen-NG blends compared to SNG from hydrogen ?

b - Same as for LAP 7.1.2

Question 8 Is there a requirement for other or additional equipment compared to a regular connection for natural gas injection in your grid? Which one?

Same as for LAP 7.1.2

Question 9a - Please describe which party is responsible for delivering which part of the connection? For example is the TSO only responsible for delivering a connection point?

a - Same as for LAP 7.1.2

Question 9b - Who can do the connection work (professional skills requirement)

b - Same as for LAP 7.1.2

Question 9c - Which party is responsible for carrying out the planning and establishment of the grid connection?

c - Same as for LAP 7.1.2

Question 10 In case of network congestion, is the TSO/DSO obliged to prioritise the injection of SNG from hydrogen instead of natural gas?

Same as for LAP 7.1.2
