A critical note on an off-grid PV-battery-PEM hydrogen TEA that folds PEM degradation, battery fade, replacement timing, and Sobol/XGBoost/SHAP interpretation into the sizing objective.PV-battery-PEM 오프그리드 그린수소 시스템에서 PEM degradation, battery fade, replacement timing, Sobol/XGBoost/SHAP 해석을 sizing objective에 함께 넣은 TEA 논문에 대한 비판적 정리.

A critical note on how fixed-efficiency electrolyzer models and low-resolution renewable data can bias green-hydrogen LCOH estimates.고정 효율 전해조 모델과 낮은 해상도의 재생에너지 데이터가 그린수소 LCOH 추정에 어떤 bias를 만드는지 비판적으로 정리한다.

A critical note on why renewable green-hydrogen TEA should treat electrolyzer degradation, replacement, and on/off operation as endogenous economic effects rather than fixed lifetime parameters.재생에너지 기반 그린수소 경제성 분석에서 전해조 degradation, 교체주기, on/off 운전을 고정 수명 파라미터가 아니라 경제성을 바꾸는 내생적 효과로 보아야 하는 이유를 정리한다.
