日本語

本レビューは、CO2削減策としての直接空気回収（DAC）の5手法を比較し、エジプトとUAEにおけるDACCSおよびCCUSの展開を初めて比較検討した。エジプトのBED&SITRAとObaiyed貯留サイト、UAEのESI、Al Reyadah、EMALを分析し、年間350トンから0.5トンのCO2回収能力と70%以上の純度を報告している。スケールアッププロジェクトの課題と実装経路を包括的に示す。

English

This review compares five Direct Air Capture (DAC) methods and provides the first comparative analysis of DACCS and CCUS deployment in Egypt and the UAE. It examines storage sites such as BED&SITRA and Obaiyed in Egypt, and ESI, Al Reyadah, and EMAL in the UAE, reporting capacities from 350 to 0.5 tons CO2 annually with purity exceeding 70%. It offers a comprehensive overview of capture technologies, deployment routes, and scaling-up challenges.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではCCUS技術の導入が進むが、中東・北アフリカ地域の比較事例は参考になる。特に、日本のCCS事業法や長期戦略と比較し、地域特有の貯留ポテンシャルと政策的枠組みの違いを理解する上で有用。

In the global GX context

This review contributes to global CCUS scholarship by comparing deployment in Egypt and the UAE, offering insights into regional storage potential and policy frameworks. It complements TCFD/ISSB-aligned disclosure by highlighting technological options for hard-to-abate sectors, relevant for transition finance decisions.

👥 読者別の含意

🔬研究者:CCUS/DACの地域比較とスケールアップ課題の概要を得るのに有用。

🏢実務担当者:中東・北アフリカでのCCUSプロジェクト参入を検討する際の技術・貯留サイト情報として参考になる。

🏛政策担当者:途上国・産油国におけるCCUS政策設計の比較材料として示唆に富む。

📄 Abstract（原文）

Carbon Dioxide (CO 2 ) levels are continuously increasing due to different human activities such as energy generation, industrial activities and industry emissions. This rise in CO 2 levels participated in development of global warming phenomena, raising earth temperature and climate change. This review paper reviews one of the solutions proposed to mitigate CO 2 levels, which is Direct Air Capture (DAC) including comparison between five different DAC methods. Moreover, this review is the first comparative review combines between Direct Air Carbon Capture and Storage (DACCS) methods and Carbon Capture, Utilization and Storage (CCUS) deployment in Egypt and the United Arab Emirates (UAE) in addition to comparing various scaling-up projects implemented in different countries. BED&SITRA and Obaiyed were the main discussed storage sites in Egypt enhanced by sensitivity analysis while in UAE it was, Emirates Steel Industries (ESI), Al Reyadah, and Emirates Aluminum (EMAL). The scaling-up projects capacities was between 350 to half tonCO 2 annually with carbon dioxide purity exceeds 70% in most of the projects. Overall, this review focused on providing a comprehensive overview of Direct Air Capture (DAC), covering capture technologies, deployment routes, CO 2 storage opportunities, challenges and different scaling-up DAC systems and implementation through reviewing relevant scholarly literature and wide range of studies.
