This study analyses the operation of selected power generating liquid hydrogen (LH2) regasification processes from recent literature. In operation for maximum power generation, the selected processes generate up to 3.9% of the lower heating value (LHV) of H2 as work, corresponding to around 4.7 MJ/kgH2 and 27% LH2 exergy in the chosen scenario. However, this operation requires unfeasible component pressure ratios of up to 300. In this study, the optimisation problems known from the literature for maximising the power generation of these LH2 regasification processes are taken up and an upper bound is set for compression pressure ratios of each process. This bound is then varied towards lower pressure ratios. Quantitatively, results show that with technically feasible component requirements—component pressure ratios well below 20 for several processes—around 2.9% LHV can still be generated as work. This corresponds to 20% LH2 exergy, or around 25% less work compared to the unbound process operation for maximum power generation. Qualitatively it is shown that the maximum power output is flat in the direction of decreasing pressure ratios. This means that the component requirements can be drastically reduced with acceptable losses in generated power. This finding can be transferred to more complex LH2 regasification processes so that the power output per LH2 mass flow can be further increased with feasible component requirements.
