A modelling approach to assessing the feasibility of the integration of power stations with steam electrolysers

The thermoneutral point of 4644 A m−2 was shown to be a guide for assessing design and operation options with heat integration possibilities after this point. For scenarios of 7% steam extraction and a purely H2 production plant, 250 MW (7500 kg h−1) and 290 MW (8700 kg h−1) H2 can be produced with SOECs sized at 43,300 and 50,100 m2, respectively.
