To be cost-competitive on the global market, solar hydrogen has to reach the cost range of hydrogen derived from steam methane reforming (SMR), which is currently the dominant hydrogen production route. SMR hydrogen is produced at costs ranging from 1-2 $/kg(H2). For this study, we therefore defined the target cost range for cost-competitiveness as 1.5-1.6 $/kg(H2), which is indicated as a grey bar in Figure . It can be seen that PV+E crosses into the target cost range at the shortest development distance. PC also reaches it at somewhat longer distances while PEC seems to mostly level off above it. To gain insight into the requirements for cost-competitiveness, we turn to a more detailed analysis of the models for each technology that fall into the target cost range.
