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.

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?

No legislation or regulations. Sweden has no transfer of gas from Sweden.

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 - Yes, if out of specification .

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 - Yes, if there are technical and security reasons.

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?

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. – Obliged to connect ii. – Yes iii. – To comply with the TSO regulations for connection.

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. – Yes ii. – Yes iii. – Depends on complexity. There is no experience so far in Sweden

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)?

Yes

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 - No. Could deny if quality is out of specification.

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 - No

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 - Yes

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 - Yes

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

b - No
