The paper presents a review of technology readiness, costs, impacts, and practical limitations of the Carbon Dioxide Removal (CDR) methods Biochar as soil additive and Bioenergy with Carbon Capture and Storage (BECCS). TRLs, costs, practical limitations, and impacts of the considered CDR methods vary greatly depending on contextually appropriate technology choices and assumptions. The analysis shows that the CDR methods should be considered as classes of CDR methods with considerable variation rather than as two homogenous CDR methods.
