據(jù)世界石油網(wǎng)報(bào)道，阿布扎比國(guó)家石油公司（ADNOC）日前啟動(dòng)了在碳酸鹽巖含水層中進(jìn)行世界上第一口完全隔離的二氧化碳注入井的工作。

這個(gè)項(xiàng)目預(yù)計(jì)將在2023年第二季度開(kāi)始注入二氧化碳，標(biāo)志著ADNOC承諾在2030年之前將其運(yùn)營(yíng)脫碳，將其碳強(qiáng)度降低25%，并在2050年前實(shí)現(xiàn)凈零碳排放目標(biāo)的又一個(gè)重要步驟。

這一創(chuàng)新項(xiàng)目將支持ADNOC的碳捕獲和存儲(chǔ)計(jì)劃，該計(jì)劃是該公司在ADNOC董事會(huì)指導(dǎo)下推進(jìn)的一系列新項(xiàng)目和舉措的一部分，以加速實(shí)施其低碳增長(zhǎng)戰(zhàn)略，并撥款150億美元用于其業(yè)務(wù)的脫碳。

一旦投入運(yùn)營(yíng)，這個(gè)項(xiàng)目最初每年將從Fertiglobe阿聯(lián)酋業(yè)務(wù)中捕獲的至少18000噸二氧化碳完全封存，用于注入阿布扎比的陸上碳酸鹽巖含水層中。 

二氧化碳注入項(xiàng)目

二氧化碳注入井項(xiàng)目建立在ADNOC在Al Reyadah的碳捕獲設(shè)施的經(jīng)驗(yàn)基礎(chǔ)上，該設(shè)施每年可捕獲80萬(wàn)噸二氧化碳。利用ADNOC廣泛的三維地震調(diào)查結(jié)果和該公司最先進(jìn)的地下建模能力，確定了二氧化碳注入的井位以及目標(biāo)地質(zhì)地層。

這個(gè)項(xiàng)目將有助于生產(chǎn)低碳氨。這種有效且具有成本競(jìng)爭(zhēng)力的氫載體可以迅速擴(kuò)大規(guī)模，并且比其他燃料的碳強(qiáng)度更低。

這個(gè)項(xiàng)目還將在ADNOC的Thamama數(shù)字卓越中心使用先進(jìn)技術(shù)進(jìn)行監(jiān)測(cè)和評(píng)估，以確保最高水平的環(huán)境安全，因?yàn)樵摴緮U(kuò)大了其碳捕獲活動(dòng)，到2030年前每年捕獲500萬(wàn)噸。

ADNOC的多年脫碳計(jì)劃

這個(gè)項(xiàng)目是ADNOC一系列脫碳舉措中的最新一項(xiàng)，其中包括ADNOC從阿聯(lián)酋水電公司(EWEC)核電和太陽(yáng)能資源獲得100%電網(wǎng)電力的里程碑式協(xié)議。這項(xiàng)協(xié)議使ADNOC成為第一家通過(guò)此類協(xié)議大規(guī)模脫碳的大型石油和天然氣公司。

此外，ADNOC最近完成了一項(xiàng)38億美元的交易，建設(shè)中東和北非地區(qū)首個(gè)海底輸電網(wǎng)絡(luò)，將ADNOC的海上業(yè)務(wù)連接到阿布扎比國(guó)家能源公司（TAQA）的清潔陸上電力網(wǎng)絡(luò)，一旦完成，可以將海上碳強(qiáng)度降低50%。

ADNOC breaks ground on world’s first fully sequestered CO2 injection project

ADNOC has begun work on the world’s first fully sequestered carbon dioxide (CO2) injection well in a carbonate saline aquifer.

The project, which is expected to begin injecting CO2 in Q2 2023, marks another important step in ADNOC’s commitment to decarbonize its operations, reduce its carbon intensity by 25% by 2030 and deliver on its net zero by 2050 ambition.

This innovative project will support ADNOC’s carbon capture and storage program, which is part of the suite of new projects and initiatives the company is advancing following the guidance by ADNOC’s Board of Directors to accelerate the delivery of its low-carbon growth strategy and the allocation of $15 billion to decarbonize its operations.

once operational, the project will initially fully sequester a minimum of 18,000 tons per annum of CO2 captured from Fertiglobe’s UAE operations for injection in Abu Dhabi’s onshore carbonate aquifers.

The CO2 injection well project builds on ADNOC’s experience with its carbon capture facility at Al Reyadah, which has the capacity to capture up to 800,000 tons of CO2 per year. The well location for CO2 injection as well as targeted geological formations were identified using the results of ADNOC’s extensive 3D seismic survey and the company’s state-of-the-art subsurface modeling capacity.

The project will contribute to the production of lower-carbon ammonia. This effective and cost-competitive hydrogen carrier can be scaled up quickly and has lower-carbon intensity than other fuels.

The project will also be monitored and assessed, using advanced technology at ADNOC’s Thamama Digital Centre of Excellence, to ensure the highest levels of environmental safety as the company expands its carbon capture activities to capture 5 million tonnes per annum by 2030.

ADNOC’s multi-year decarbonization plan

The project is the latest in a series of decarbonization initiatives, including a landmark agreement for ADNOC to acquire 100% of its grid power from the Emirates Water and Electricity Company’s (EWEC) nuclear and solar sources. This agreement makes ADNOC the first major oil and gas company to decarbonize its power at scale through an agreement of this kind.

Additionally, ADNOC recently reached financial close on a $3.8 billion deal to build a MENA first-of-its-kind sub-sea transmission network, connecting ADNOC’s offshore operations to TAQA’s clean onshore power network which once complete, could reduce offshore carbon intensity by up to 50%.
