What it is
Multi-objective optimization of a combined-cycle power plant (CCPP) integrated with LOHC hydrogen production. One Aspen Plus model and an automated DOE pipeline feed two analysis tracks: linear regression for the publication, ML surrogates + NSGA-II for large-scale optimization.
Highlights
- Zero-penalty heat-recovery zone found — at the best integration point, LOHC production causes no measurable loss of CCPP power output
- Four integration lines ranked by power penalty: Line 6 < Line 5 < Line 9 < Line 4
- LOHC competes only with steam-turbine efficiency, not the full plant — the penalty scope is narrower than expected
- Surrogate models (RF · GB · NN · GP) + NSGA-II enable thousands of evaluations per minute for Pareto-front exploration
