“…The major chicken-and-egg dilemma in the development of the hydrogen economy is whether to build the necessary infrastructure first, including hydrogen fueling stations (HFS) [21], or whether to develop hydrogen applications first, including hydrogen fuel cells (HFC) [22], hydrogen fuel cell vehicles (HFCV) [23] or hydrogen internal combustion vehicles [7,24]. Katikaneni et al [25] perform feasibility analysis to reveal the on-site hydrogen generation using existing fueling station could support development of hydrogen production and applications [26]. This investigation discusses first three classes of hydrogen industries in the hydrogen supply and sales chain.…”
