Technoeconomic analysis of different options for the production of hydrogen from sunlight, wind, and biomass

Method for size optimisation of large wind–hydrogen systems with high penetration on power grids

“…Our results are based on many Refs. [13,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] and are graphically shown in Figs. 3-5.…”

“…We assumed that the replacement costs were equal to the capital costs, whereas annual operating costs (Table 2) have been fixed according to a literature review [6,13,[23][24][25]36,[41][42][43].…”

Exergoeconomic analysis of a PEM electrolyser at various operating temperatures and pressures

“…The capital cost of the electrolyser C elect , could range from as high as 3000 $ kW À1 to as low as 300 $ kW À1 for mass production and large capacities that are greater than 5 MW (Padro and Putsche, 1999;Gonzalez, 2002;Thomas and Kuhn, 1995;Mann et al, 1998;Stuart Energy, 2002). In the current analysis, an electrolyser cost of 600 $ kW À1 of power input is used, which is consistent with the rate suggested by Mann et al (1998) and several DoE studies.…”

The role of hydrogen in high wind energy penetration electricity systems: The Irish case

“…The specific cost of the electrolyser together with the balance-of-plant has been set constant at 1100 4/kW, a rather optimistic estimate at present (especially in the low power range) but realistic for large-scale systems (several megawatts) in the medium term. Costs are expected to drop further in the long term to 600 4/kW or even less [23]. The lifetime of the electrolysis facility is 20 years, but the cell stacks would need to be replaced after 10 years at an estimated cost of 700 4/kW.…”
