據(jù)6月14日離岸能源報道，DNV船級社已經(jīng)對北海Greensand項目二氧化碳儲存的各個方面進行了安全性驗證。

Greensand項目包括在英力士位于比利時Zwijndrecht的工廠捕獲二氧化碳，并將其跨境運輸并儲存在丹麥北海Nini油田。注入的二氧化碳被儲存在水下1800米的深處。

據(jù)悉，該項目是世界上第一個證明二氧化碳可以跨越國界運輸并儲存在海上以緩解氣候變化的項目。

該安全驗證涵蓋了從單個分包商的制造到海上安裝的所有內(nèi)容。

DNV客戶關(guān)系區(qū)域主管兼安全驗證項目總監(jiān)Mick Cramer Jakobsen表示，“我們的專家團隊與Greensand密切合作，在過去幾年中一直關(guān)注項目的發(fā)展。我們對Greensand項目整個試點階段的安全驗證清楚地表明，該項目安全，符合戰(zhàn)略目標，符合所有相關(guān)的丹麥法規(guī)和國際法規(guī)及最高標準。當然，在Greensand下一階段開始之前進行安全驗證將是有益的”。

DNV表示，其工作包括對計劃的廣泛分析，地下場地的適用性，存儲和設(shè)計的實用性，以及公司在單個子元件壓力測試期間的實際情況，整個價值鏈和跨國界海上系統(tǒng)的連接和安裝的批準。

3月8日，丹麥王儲弗雷德里克殿下正式為丹麥地下二氧化碳儲存庫揭幕。當天晚些時候，DNV代表提交了Greensand項目的符合性聲明。

Greensand項目背后的財團由23家公司、大學(xué)和研究機構(gòu)組成，其中包括英力士和溫特斯豪 Dea。

在短期內(nèi)，Greensand項目在2025至2026年每年可儲存多達150萬噸二氧化碳。在計劃于2030年開始的最后擴展階段，該項目的目標是在該地區(qū)每年儲存多達800萬噸二氧化碳，占丹麥總減排目標的40%。

今年2月，英力士和溫特斯豪Dea獲得了丹麥北海第一個全面的二氧化碳儲存許可證。

項目的FID將在概念驗證后開始，計劃于2023年下半年開始，預(yù)計交付時間約為兩年，碳儲存可能從2025年左右開始運行。

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.
