大気中CO2濃度上昇に対し、藻類を用いたCO2隔離（CCUS）の可能性をレビュー。光合成効率40-93.7%、最大20%のCO2固定が可能で、1300万エーカーで5000万トンCO2を捕獲し300万トンのバイオマスを生産。光バイオリアクター等の技術や遺伝子工学による固定促進、炭素クレジット制度・政策枠組みについても議論。
English
This chapter reviews algal-based CO2 sequestration as a sustainable CCUS method. Microalgae have photosynthetic efficiency of 40-93.7% and can fix up to 20% of CO2. Massive production on 13 million acres could capture 50 million tons of CO2 and produce over 3 million tons of biomass. Technologies like photobioreactors and genetic engineering, along with carbon credit regimes and policy frameworks, are discussed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもCCUS技術への関心が高まっており、特に藻類を活用したCO2固定と炭素クレジットの連携は、カーボン・クレジット制度（J-クレジットなど）との親和性が期待される。本レビューは政策面での示唆を提供する。
In the global GX context
This review connects algal CCUS with carbon credit mechanisms, relevant as global carbon markets expand under Paris Agreement Article 6. While not Japan-specific, it provides a technical-economic-policy overview valuable for integrating biological CCUS into national net-zero strategies.
👥 読者別の含意
🔬研究者:Offers a comprehensive overview of algal CCUS technologies and their potential, including carbon fixation rates and genetic engineering approaches.
🏢実務担当者:Provides insights into carbon credit frameworks and policy conditions for implementing algal-based carbon capture projects.
🏛政策担当者:Highlights the need for quantifiable and verifiable algal systems in carbon markets to support net-zero targets.
📄 Abstract（原文）
With a rapid accumulation of atmospheric CO2, which has grown 47% throughout the industrial revolution and currently stands at 409.8 ppm in 2019, global warming is intensifying and needs innovative solutions. This chapter reviews algal-based sequestration of CO2 as a sustainable method of carbon capture, utilization, and storage. The photosynthetic efficiency of microalgae ranges at 40-93.7% and fix up to 20% of the CO2. Massive production on 13 million acres could capture 50 million tons of CO2 and produce more than 3 million tons of biomass. Recent growth technologies comprise photobioreactors, hybrid systems, artificial carbon concentration systems, and genetic and metabolic engineering to enhance the rate of fixation. Carbon credit regimes, technological-economic analyses, and policy frameworks for enabling quantifiable and verifiable algal systems in carbon markets are also studied. Overall, the innovation of algal carbon sequestration blocks scientific, economic, and environmental policy progress to global net-zero carbon emissions and a circular bioeconomy.
