The original datasets for hydrogen production for PEM (hydrogen production, gaseous, 30 bar, from PEM electrolysis, from grid electricity), AEC (hydrogen production, gaseous, 20 bar, from AEC electrolysis, from grid electricity) and SOEC (hydrogen production, gaseous, 1 bar, from SOEC electrolysis, from grid electricity) have an electricity input of 54 kWh, 51.8 kWh and 42.3 kWh, respectively. However, after calling ndb.update('biofuels') to an IMAGE, SSP2-RCP26, 2050 scenario, these amounts are drastically increased, as the new regional 'market for electricity' inputs seem to be misscalculated.
Example:
'hydrogen production, gaseous, 1 bar, from SOEC electrolysis, from grid electricity' (WEU) has now 20 electricity inputs, all of them of 40.6 kWh each. Thus, now the electricity input of the activity is 812 kWh instead of the original 42.3 kWh in the imported dataset.
Something similar happens with AEC and PEM electrolysis activities.

Sorry if I am missing something!
