海外有望企業情報Gigablue

Gigablueは鉄やマンガン等を組み込んだセルロース製の生分解性微小粒子を海洋へ散布し、その粒子表面に微細藻類を生育させることで大気中のCO2をキャプチャする技術を開発している。固定された炭素はセルロース粒子上の微細藻類由来の有機物とともに海中に沈んでいき、深層海へ輸送・蓄積されることで海底での長期間の炭素隔離を目指す。同社は中核技術として、生分解性微小粒子によるCO2除去量の測定、継続監視、報告、第三者検証の仕組みを構築しており、海洋観測、水質分析、環境DNA解析、深海モニタリング等を活用して、信頼性と持続性の高いカーボンクレジットの創出を行う。

Gigablue has developed a technology that deploys biodegradable cellulose-based microparticles containing iron, manganese, and other nutrients into the ocean, where microalgae grow on the surface of the particles and capture atmospheric CO2. The captured carbon is transported and stored in the deep ocean as the microalgae-derived organic matter sinks together with the cellulose particles, with the aim of achieving long-term carbon sequestration on the seafloor. As a core element of its technology platform, the company has established a Measurement, Monitoring, Reporting, and Verification (MMRV) framework to quantify, continuously monitor, report, and independently verify the amount of CO2 removed through its biodegradable microparticle system. By leveraging oceanographic observations, water quality analysis, environmental DNA monitoring, and deep-sea tracking technologies, Gigablue seeks to generate high-integrity, durable carbon removal credits.
