據(jù)6月14日離岸能源報(bào)道，DNV船級社已經(jīng)對北海Greensand項(xiàng)目二氧化碳儲(chǔ)存的各個(gè)方面進(jìn)行了安全性驗(yàn)證。

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

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

該安全驗(yàn)證涵蓋了從單個(gè)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(yàn)證項(xiàng)目總監(jiān)Mick Cramer Jakobsen表示，“我們的專家團(tuán)隊(duì)與Greensand密切合作，在過去幾年中一直關(guān)注項(xiàng)目的發(fā)展。我們對Greensand項(xiàng)目整個(gè)試點(diǎn)階段的安全驗(yàn)證清楚地表明，該項(xiàng)目安全，符合戰(zhàn)略目標(biāo)，符合所有相關(guān)的丹麥法規(guī)和國際法規(guī)及最高標(biāo)準(zhǔn)。當(dāng)然，在Greensand下一階段開始之前進(jìn)行安全驗(yàn)證將是有益的”。

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

3月8日，丹麥王儲(chǔ)弗雷德里克殿下正式為丹麥地下二氧化碳儲(chǔ)存庫揭幕。當(dāng)天晚些時(shí)候，DNV代表提交了Greensand項(xiàng)目的符合性聲明。

Greensand項(xiàng)目背后的財(cái)團(tuán)由23家公司、大學(xué)和研究機(jī)構(gòu)組成，其中包括英力士和溫特斯豪 Dea。

在短期內(nèi)，Greensand項(xiàng)目在2025至2026年每年可儲(chǔ)存多達(dá)150萬噸二氧化碳。在計(jì)劃于2030年開始的最后擴(kuò)展階段，該項(xiàng)目的目標(biāo)是在該地區(qū)每年儲(chǔ)存多達(dá)800萬噸二氧化碳，占丹麥總減排目標(biāo)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(gè)全面的二氧化碳儲(chǔ)存許可證。

項(xiàng)目的FID將在概念驗(yàn)證后開始，計(jì)劃于2023年下半年開始，預(yù)計(jì)交付時(shí)間約為兩年，碳儲(chǔ)存可能從2025年左右開始運(yùn)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.
