Denmark opened the Greensand offshore CO2 storage project on 18 September, moving from pilot testing toward commercial operation.[5][8] King Frederik X inaugurated the project in Esbjerg, with INEOS working alongside Harbour Energy and the Danish state company Nordsøfonden.[5] Regular operations are intended to store up to 400,000 tonnes of CO2 a year at the depleted Nini West oil field.[5]
The transport chain starts with CO2 captured from biogas production, which is liquefied and moved to temporary storage at the Port of Esbjerg.[8] A dedicated carrier then takes the cargo offshore to Nini West, where it is injected around 1,800 metres beneath the seabed.[8] The project required new CO2 handling facilities at the port and a dedicated offshore transport operation.[8]
The European Union's Innovation Fund supports Greensand Future with a grant of 41 million euros, and the project aims to store around 2.4 million tonnes over eight years.[8] It builds on a 2023 pilot that demonstrated transport across national borders and injection into offshore geological storage.[8] The partners plan to increase storage volumes as additional sources of captured CO2 become available.[8]
