Recent study and analysis show that the decline in the cost of hydrogen projects cannot be estimated solely on the basis of doubling the installed capacity of electrolyzers. Growth may result from increasing stack and plant sizes, while a large share of the cost remains outside the stack itself, in equipment, engineering, construction, and electrical systems.
A technical article from Semiconductor Engineering, based on four crash studies, explains that training-data volume and model accuracy are more closely linked to the smoothness of the physical response than to the number of design variables or model size. It proposes using learning curves, error bounds, and variable importance to reduce costly simulation experiments.
