Market Survey on the Need for Mixing Green Hydrogen with Gas

Lithuania's gas transmission system operator Amber Grid plans to develop a network for transporting pure green hydrogen (hereinafter referred to as H2) in Lithuania, i.e., pipelines between hydrogen producers and consumers in Lithuania and connections with other countries.

The development of H2 infrastructure in Lithuania will be important for the decarbonization of the economy and ensuring energy independence. The first solutions for the pure H2 network are expected to be implemented after 2030.

In addition, Amber Grid is considering creating the possibility for H2 producers to supply (under certain conditions) H2 into the existing natural gas system. According to current natural gas quality requirements, the mixed hydrogen could constitute up to 0.1% by volume of the gas transported through the pipelines, and with certain investments in infrastructure, the concentration of hydrogen could be increased to 2% of the transported gas volume.

Survey Objective: To assess the need for hydrogen supply/blending into the existing natural gas transmission system.

It is important to identify potential production locations for green H2 intended for blending into the existing natural gas transmission system, the size of capacities, and the periods when the need for H2 transportation is expected to arise.

For this purpose, we are initiating a survey of interested parties and invite all those who plan to produce H2 and supply it into the existing natural gas transmission system to participate.

Please fill in the survey here. Your responses are expected till 3rd July, 2024.

More information about hydrogen and Amber Grid plans can be found on our website.

If you have additional information, questions, or comments related to the questionnaire, please contact the Energy Transformation Center of Amber Grid (email:, or - the Renewable Energy Technology Manager Andrius Šostakas, email:

By completing this survey, you agree that the information you provide will be used by Amber Grid for planning the adaptation of the existing natural gas transmission infrastructure for hydrogen transportation and for coordinating such plans with state institutions.

Your contribution is important in shaping the vision of H2 transmission infrastructure in Lithuania!

Public consultation on the gas transmission network development plan 2024-2033 announced

Amber Grid, the Lithuanian gas transmission system operator, organises a public consultation on its ten-year gas transmission network development plan. Plan you will find here

“The plan sets out clear steps to strengthen Lithuania’s energy independence, expand the diversity of energy sources, and ensure further regional integration in Lithuania and beyond. Lithuania, like other European countries, is not only ensuring the reliability of the existing infrastructure, but is also preparing for the creation of a hydrogen transport network to deliver green hydrogen to Lithuanian consumers and to meet the needs of the European Union,” says Nemunas Biknius, CEO at Amber Grid.

Some key aspects of Amber Grid’s ten-year network development plan:

  • Upgrading the existing gas infrastructure and increasing resilience to crisis situations,
  • Developing alternative energy sources, integrating renewable energy,
  • Developing a hydrogen transport network, synergies between the gas and electricity sectors,
  • Reducing greenhouse gases (GHG).

Please send your comments and suggestions on Amber Grid’s ten-year development plan by email to up to and including 14 June 2024. In the subject line, please indicate that this is a response to the public consultation on Amber Grid’s ten-year development plan. If your response contains confidential aspects, please indicate which information should not be made public when summarising the results of the consultation.

Public consultation on Amber Grid tariffs’ methodology and indicative 2024-2028 tariffs
Due to the transmission tariff methodology changes for upcoming regulatory period (2024-2028) the National Energy Regulatory Council (LT NRA), on 2nd December 2022, published public consultation on the reference price methodology for determining the tariffs of services provided by the Lithuanian natural gas transmission system operator AB Amber Grid for year 2024-2028. If new significant changes would appear during  new regulatory period these changes would be consulted again. 
The consultation is carried out based on European Commission Regulation (EU) 2017/460 of 16 March 2017 establishing a network code on harmonised transmission tariff structures for gas (TAR NC), both Art. 26 of TAR NC (Periodic consultation, covering reference price methodology, tariffs and their derivation, and mandatory to be repeated at least every 5 years) and Art. 28 (Consultation on discounts, multipliers and seasonal factors).
The document of public consultation, tariff models are available here
Final decision on tariffs will be adopted by the LT NRA after assessing comments and proposals to be received from the Agency for the Cooperation of Energy Regulators (ACER) by May 31st, 2023.
We would like to invite all interested parties to submit any comments and proposals for this consultation document by e-mail to (with copy to and no later than February 1st 2023.
Regional consultation on market needs for the activities related to Guarantees of Origin

Transmission system operators in the Baltic States and Finland are organizing a joint regional consultation on the market needs for the activities related to Guarantees of Origin and overall market potential in Baltic and Finnish region

The Transmission System Operators (TSOs) Amber Grid, Conexus Baltic Grid, Elering and Gasgrid Finland, from which Amber Grid and Elering are operating national GO issuing body and Gasgrid starting to operate from 2022 April, while Conexus Baltic Grid could become national GO issuing body in the future, organize a joint consultation questionnaire on the market needs for the activities related to Guarantees of Origin (hereinafter GOs) and overall market potential in Baltic and Finnish region.
This year Amber Grid, Conexus Baltic Grid, Elering and Gasgrid Finland signed Memorandum of Understanding on promoting development of green gases. Among other topics TSOs agreed to promote harmonized digital cross-border GOs exchange in the region. TSO agreed to promote GO mutual recognition measures, as foreseen in RED II, laws, regulations and other documents such as policies and standards building upon it or otherwise related to it, and respect the additional criteria, which are established in country of each TSO.
In order to develop GOs cross border exchange solution that the best fulfills the needs of market participants and stakeholders, we would kindly invite you to participate in this consultation. 
The received opinions will be used as a base for TSOs for prioritizing future GOs market development and related activities in the Finnish-Baltic countries.
All information (incl. contact details) provided by the Respondents in the consultation questionnaire will be shared between the TSOs. TSOs will not publish consultation responses with Respondents' personal information, but the results may be compiled and published to increase transparency. Any public summary will be composed in a manner that ensures anonymity. The results may also be presented for the ministries and other authorities responsible for governing GOs and development of green gases in the Finnish-Baltic market area. 
Please provide your answers to the Consultation questionnaire by 31st of January.
