CO₂ Corrosion Rate Prediction Model for Well Tubing in CCUS Process

日本語

CCUSシステムにおける坑管のCO₂腐食速度予測モデルを提案。温度、圧力、CO₂濃度などの主要パラメータを考慮し、CCUS井戸の安全性と寿命向上を目指す。大規模炭素貯蔵の信頼性確保に貢献。

English

This study proposes a prediction model for CO₂ corrosion rate in well tubing within CCUS systems. It incorporates key parameters such as temperature, pressure, and CO₂ concentration, aiming to improve the safety and longevity of CCUS wells, thereby supporting large-scale carbon storage operations.

日本のGX文脈において

日本ではCCUSがGXの重要施策として位置づけられており、坑井の長期的な健全性評価は実用化の鍵。本モデルはSSBJ非財務情報開示においても、CCUS実績の信頼性を示す技術的根拠となり得る。

In the global GX context

Globally, CCUS is critical for net-zero targets, and well integrity is a key operational risk. This model directly addresses the need for reliable corrosion prediction, which is essential for project financing, regulatory approval, and long-term carbon storage certification under frameworks like ISO 27914.
