Points about industrial hydrogen production by electrolysis 

According to [AND 12 HAM 11], the markets that currently exist for industrial players in PEM electrolysis are essentially  

56 Services to the grid, such as participation in its stabilization, are obviously envisaged. 

The common point between these applications is a need for very pure hydrogen, which PEM technology can serve more easily than can alkaline technology, although the ground truth is not quite as simple as this affirmation, particularly at an industrial level. The problem of the energy cost of electrolysis is of little importance in these applications it is essentially the cost of the initial investment, and also that of maintenance, possibly, which is important.
