Underlying economics: From the intersections of fuel-switching CO2 prices in time, we derive five fuel-switching points that capture the increasing competitiveness of green hydrogen with blue hydrogen. In general, high residual emissions close the competitiveness window of bridging options. 3/9

Nice conceptualization and chart! 👏

We quantify these fuel-switching points by combining progressive and conservative cases for green and blue hydrogen supply - as well as low and high gas prices. (I know it is a complex figure: the legend explains the milestones. pls see equations and theory in the paper) Main results are... 4/9
