Denmark has started a project to store carbon dioxide 1,800 meters beneath the North Sea, making it on track to be the first country in the world to bury CO2 that has been imported from elsewhere.
The CO2 will be injected on the site of an exhaustive oil field. The “Greensand” initiative, led by the German oil giant Wintershall Dea and the British chemical company Ineos, aims to store up to eight million tonnes of CO2 annually by 2030.
Project Greensand strives to make it possible for Denmark to utilize CO2 storage as a component of the country’s response to climate issues
Project Greensand strives to make it possible for Denmark to utilize CO2 storage as a component of the country’s response to climate issues. 23 Danish and foreign partners who have competence in the transport, storage, and monitoring of CO2 underground have joined the initiative.
Companies from Denmark and abroad as well as research centers, universities, and start-ups are represented among the members.
The project seeks to transform in a green way. In addition to installing solar cell systems and constructing offshore wind farms, the country is also transitioning to electric vehicles from gasoline and diesel vehicles. The Paris Agreement’s goals must be met in order to overcome climate concerns, according to Denmark, even though all of these efforts are in the right path.
The project website stated, “We must also capture CO2 from the emitters and store it,” noting that the UN’s climate panel views CO2 capture and storage as a powerful weapon for quickly reducing CO2 emissions.
The project is now in the pilot phase
Project Greensand is the most developed CO2 storage project in Denmark. It has the capacity to store up to 8 million tonnes of CO2 year by 2030 and up to 1.5 million tonnes of CO2 annually in 2025–2026.
The project is now in phase 2, often known as the pilot phase. Here, the project is developed and put on display.
CO2 will be transported from Antwerp in Belgium to the Nini platform in the North Sea for storage. It is liquefied and shipped or piped to reservoirs like geological holes or depleted oil and gas fields, where it is then kept indefinitely.
The CO2 is permanently stored in a reservoir 1,800 meters below the surface of the ocean.
On the Nini field, geological and production data have been gathered for more than 20 years. The project website said that this indicates that the project’s key partners, INEOS and Wintershall Dea, are well knowledgeable about the subsurface infrastructure.
