据世界石油网报道，阿布扎比国家石油公司（ADNOC）日前启动了在碳酸盐岩含水层中进行世界上第一口完全隔离的二氧化碳注入井的工作。
这个项目预计将在2023年第二季度开始注入二氧化碳，标志着ADNOC承诺在2030年之前将其运营脱碳，将其碳强度降低25%，并在2050年前实现净零碳排放目标的又一个重要步骤。
这一创新项目将支持ADNOC的碳捕获和存储计划，该计划是该公司在ADNOC董事会指导下推进的一系列新项目和举措的一部分，以加速实施其低碳增长战略，并拨款150亿美元用于其业务的脱碳。
一旦投入运营，这个项目最初每年将从Fertiglobe阿联酋业务中捕获的至少18000吨二氧化碳完全封存，用于注入阿布扎比的陆上碳酸盐岩含水层中。
二氧化碳注入项目
二氧化碳注入井项目建立在ADNOC在Al Reyadah的碳捕获设施的经验基础上，该设施每年可捕获80万吨二氧化碳。利用ADNOC广泛的三维地震调查结果和该公司最先进的地下建模能力，确定了二氧化碳注入的井位以及目标地质地层。
这个项目将有助于生产低碳氨。这种有效且具有成本竞争力的氢载体可以迅速扩大规模，并且比其他燃料的碳强度更低。
这个项目还将在ADNOC的Thamama数字卓越中心使用先进技术进行监测和评估，以确保最高水平的环境安全，因为该公司扩大了其碳捕获活动，到2030年前每年捕获500万吨。
ADNOC的多年脱碳计划
这个项目是ADNOC一系列脱碳举措中的最新一项，其中包括ADNOC从阿联酋水电公司(EWEC)核电和太阳能资源获得100%电网电力的里程碑式协议。这项协议使ADNOC成为第一家通过此类协议大规模脱碳的大型石油和天然气公司。
此外，ADNOC最近完成了一项38亿美元的交易，建设中东和北非地区首个海底输电网络，将ADNOC的海上业务连接到阿布扎比国家能源公司（TAQA）的清洁陆上电力网络，一旦完成，可以将海上碳强度降低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%.
