Project N05-A
The Netherlands is committed to a carbon-neutral energy supply by 2050. During this energy transition, both the Netherlands and Germany will still need gas. The use of natural gas will, however, decline in the coming years, due to energy savings and the switch to energy from renewable sources. In this energy transition, natural gas is a flexible and necessary energy source. Alternative energy sources such as wind, solar or biogas cannot yet take over the role of gas in the coming decades. Natural gas is still the most important energy source for heating our homes and buildings. Natural gas also provides the high temperatures required in industry. Gas production in the Netherlands is cheaper and less polluting than gas imported from abroad. Moreover, it ensures a more independent energy supply. Read more about the importance of natural gas…
ONE-Dyas, together with partners Hansa Hydrocarbons and EBN, will extract gas from the GEMS area. GEMS, which stands for ‘Gateway to the Ems’, refers to a location in the North Sea, just north of the mouth of the Ems, situated on the border between the Netherlands and Germany. The GEMS area contains small fields that may hold natural gas.
Since the summer of 2024, the N05-A production platform has been installed in the Dutch North Sea, 20 kilometres north of Borkum, Rottumerplaat and Schiermonnikoog. The N05-A platform is the Netherlands’ first offshore gas processing platform in the North Sea to run entirely on offshore wind energy. Thanks to a cable connecting to the nearby German Riffgat wind farm, there are near zero emissions during gas extraction. The platform has been designed to be suitable for the production of green hydrogen and CO₂storage in the near future. Read more about production platform N05-A…
Following an exploratory drilling in the GEMS area, another gas field has been identified. The field N04-A is located 30 km north of the islands. ONE-Dyas also intends to develop this gas field. This requires various permits, and an environmental impact assessment is being prepared. The future electrified N04-A platform is smaller than production platform N05-A because it transmits the natural gas directly to the nearby N05-A. The N05-A platform processes the gas and prepares it for transport to shore. Read more about developments regarding the N04-A field…
NEWS OVERVIEW
North Sea gas production expanded: second production well N05-A brought on stream
7 April 2026
ONE-Dyas has started gas production from the second production well on the N05-A platform in the North Sea. This increases N05-A’s production to 1 billion cubic metres per year. As a result,
N05-A is already making a significant contribution to the gas supply of the Netherlands and Germany, at a time when energy security and geopolitical stability are high on the agenda.

PLATFORM N05-A
A milestone in the North Sea: N05-A is the first gas platform powered by offshore wind energy
December 2025
ONE-Dyas, together with its partners EBN and Tenaz Energy has reached a milestone in the energy transition: the cable connection between the N05-A platform and the German offshore wind farm Riffgat is complete and is being used to produce natural gas. This makes N05-A the first natural gas production platform in the Dutch and German North Sea to run on offshore wind energy.

Permits and licences
The GEMS project goes through four phases, exploration, discovery, production and decomissioning. For the N05-A field, the exploration and discovery phase was completed in 2018. Permits are required before the production phase can start.
On 16 October 2021, ONE-Dyas submitted the permit applications for the N05-A project (including the EIA) to the Dutch Ministry of Economic Affairs. On 23 April 2021, the Ministry of Economic Affairs made the draft decisions for this project available for public inspection.
Until 3 June 2021 stakeholders could submit their views and ask questions via www.rvo.nl/gaswinning-N05. Read more.
EXPLORATION
Verkennen - 3D seismisch onderzoek. Om de ondergrondse situatie in kaart te brengen is zogenaamd seismisch onderzoek uitgevoerd. Dit onderzoek laat zien of en op welke diepte er winbaar aardgas aanwezig is in de ondergrond. In 2019 wil ONE verder seismisch onderzoek gaan uitvoeren.
DISCOVERY
Opsporen - Proefboringen. Nadat seismisch onderzoek is uitgevoerd, moeten proefboringen uitwijzen of de voorraden daadwerkelijk aanwezig zijn en de moeite van het winnen waard zijn. In 2017 en 2018 heeft ONE op twee locaties proefboringen gedaan. Voor de periode 2019-2021 staan verdere proefboringen gepland.
EXTRACTION
Winnen - N05-A productieplatform en pijpleidingen. Om het gas in het N05-A veld te kunnen produceren dient er een platform geplaatst te worden. ONE onderzoekt hoe dit platform eruit zou komen te zien en welke apparatuur noodzakelijk is. Er zijn verschillende opties om het gas naar land te brengen. Minimalisatie van milieueffecten is een belangrijke parameter bij de selectie van het platform en de route naar land. ONE wil deze keuzes begin 2019 maken en het productieplatform in de periode 2021/2022 plaatsen.
DECOMMISSIONING
Opruimen - Ontmanteling. Als de projecten zijn afgerond worden de platformen en pijpleidingen ontmanteld. Uitgangspunt daarbij is dat de locatie weer in de oorspronkelijke staat wordt achtergelaten.
