据6月14日离岸能源报道，DNV船级社已经对北海Greensand项目二氧化碳储存的各个方面进行了安全性验证。
Greensand项目包括在英力士位于比利时Zwijndrecht的工厂捕获二氧化碳，并将其跨境运输并储存在丹麦北海Nini油田。注入的二氧化碳被储存在水下1800米的深处。
据悉，该项目是世界上第一个证明二氧化碳可以跨越国界运输并储存在海上以缓解气候变化的项目。
该安全验证涵盖了从单个分包商的制造到海上安装的所有内容。
DNV客户关系区域主管兼安全验证项目总监Mick Cramer Jakobsen表示，“我们的专家团队与Greensand密切合作，在过去几年中一直关注项目的发展。我们对Greensand项目整个试点阶段的安全验证清楚地表明，该项目安全，符合战略目标，符合所有相关的丹麦法规和国际法规及最高标准。当然，在Greensand下一阶段开始之前进行安全验证将是有益的”。
DNV表示，其工作包括对计划的广泛分析，地下场地的适用性，存储和设计的实用性，以及公司在单个子元件压力测试期间的实际情况，整个价值链和跨国界海上系统的连接和安装的批准。
3月8日，丹麦王储弗雷德里克殿下正式为丹麦地下二氧化碳储存库揭幕。当天晚些时候，DNV代表提交了Greensand项目的符合性声明。
Greensand项目背后的财团由23家公司、大学和研究机构组成，其中包括英力士和温特斯豪 Dea。
在短期内，Greensand项目在2025至2026年每年可储存多达150万吨二氧化碳。在计划于2030年开始的最后扩展阶段，该项目的目标是在该地区每年储存多达800万吨二氧化碳，占丹麦总减排目标的40%。
今年2月，英力士和温特斯豪Dea获得了丹麦北海第一个全面的二氧化碳储存许可证。
项目的FID将在概念验证后开始，计划于2023年下半年开始，预计交付时间约为两年，碳储存可能从2025年左右开始运行。

Project Greensand gets DNV’s safety approval
Classification society DNV has verified the safety of all aspects of Project Greensand’s CO2 storage in the North Sea.
Project Greensand includes capturing CO2 at an INEOS Oxide site in Zwijndrecht, Belgium, which is transported cross-border and stored in the Nini field in the Danish North Sea. The CO2 injected is stored at a depth of about 1,800 meters below the seabed.
The project is said to be the first in the world to demonstrate that CO2 can be transported across national borders and stored offshore to mitigate climate change.
This safety verification covers everything from the fabrication by the individual subcontractors to the offshore installation.
“Our team of experts have worked closely with the Greensand consortium and followed the development of the project over the last few years,” said Mick Cramer Jakobsen, Regional Head of Customer Relations for DNV and project director for the safety verification.
“Our safety verification of Project Greensand’s entire pilot phase clearly shows that the project is fit for purpose, safe and compliant with all relevant Danish and international regulations and the highest standards. Naturally, it will be advantageous to have the safety verification already in place before the next phase of Project Greensand commences.”
DNV said its work had involved extensive analyses of plans, the suitability of the underground sites, and the practicability of the storage and designs, along with the company’s physical presence during a stress test of the individual sub-elements and approval of the connection and installation of offshore systems throughout the value chain and across national borders.
On 8 March, HRH Crown Prince Frederik of Denmark officially opened the underground storage of CO2 in Denmark. Later in the day, representatives from DNV presented the Statement of Conformity to Project Greensand.
The consortium behind Project Greensand consists of 23 companies, universities and research institutions, including INEOS and Wintershall Dea.
In the short run, Project Greensand can store up to 1,5 million tonnes of CO2 per year in 2025/2026. In the final expansion phase, scheduled to begin in 2030, the project aims to store up to 8 million tonnes of CO2 per year in the area, 40 per cent of Denmark’s total emission reduction target.
This February, INEOS and Wintershall Dea received the first full-scale CO2 storage permit for the Danish North Sea.
The FID for the full-scale project will commence after proof of concept, planned in the second half of 2023, and will have an estimated delivery duration of around two years after which carbon storage could be operational from around 2025.
