No, the existing capacity defined HYGNINDtscap and HYGNINDtsmer is not at all sufficient for the demands in 2017 & 2018, because of the following:

– Your hydrogen demand profile for DEMHYGNINDcap and DEMHYGNINDmer is not even, but relatively steep. The peak occurs in timeslice S19Q04, where the demand fraction is 0.00208333 and the year fraction is 0.000494693, which gives a peak load being 4.21 times the annual average. Your peak duration time is thus only 2080 hours. More importantly, the total load in season S19 is 3.37287 times the average, which means that, for example, the production capacity of METHANEREFmer should be 3.74 times the annual demand (taking into account the storage efficiencies), unless you have seasonal storage. That would require a capacity of 106.4, but the existing capacity (defined by PRC_RESID) was only 43.5 in your model. So, it is far from sufficient.

– You have no seasonal storage for HYGNINDtscap and HYGNINDtsmer (earlier you had STS storage in the model, but for some reason no such any longer), and so the calculation above is valid. I have also verified it by testing with your model, and therefore I increased the capacities of METHANEREFmer and METHANEREFcap accordingly, to eliminate the dummy imports. In reality, existing supply capacities must of course satisfy the historical demand.
