A key role in the energy transition

​​​​​​​​​​​​​​​​Low-carbon gases, such as biogas, bio methane, or hydrogen produced via electrolysis by using renewable-generated electricity (from wind, solar, etc.), are important contributors for transitioning towards a less fossil fuel dependent and, ultimately, carbon-neutral energy sector.

In this transition, the gas transportation system would need to develop according to the decarbonisation and climate neutrality objectives of the Energy Union. The Council of the European Union noted that by 2050 “green gases" – mainly H2 and bio methane – could represent 30% to 70% of total gas use. Existing gas networks could contribute to this energy transition by adapting or repurposing to handle bio methane, admixtures of hydrogen and natural gas, or pure hydrogen. ​

What's the role of ACER?

​ACER has looked into the current possibilities for admixing hydrogen and injecting biomethane or transporting pure hydrogen via existing gas networks, as well as network adaptations to allow this in the future.

Selected investments will be needed to gradually increase the ability to accept “green" gases. These types of new investments may deserve greater attention in gas network development plans.  Technology developments, legal, regulatory, and network development efforts should go hand in hand to achieve an efficient and timely decarbonisation of the gas sector.

ACER and the NRAs will continue working together in exploring regulatory options for this to happen in the most efficient way for energy consumers.​​​
