“…It is verified in the scientific literature that the extended term PEM, still very widespread, now refers to polymer electrolyte membrane, [277][278][279] with some mixed nomenclature meaning referred as polymer exchange membrane, 280 instead of its previous typical use of proton exchange membrane, given that it is this characteristic that sets it apart from other hydrogen production technologies. In addition, the term membrane is also excluded from the nomenclature associated with the technology, being referenced only simply as PE (polymer electrolyte), with extended use of PEFC (polymer electrolyte fuel cell), [281][282][283] where it differs from the term PEM, which remains used in this case to speak only of the polymeric membrane electrolysis, 284 and not of the devices or technology, as it has been done until now.…”

Summary Water‐based hydrogen production is currently an attractive research field, as it provides a greener method to produce hydrogen than existing alternatives. Green hydrogen is expected to progressively replace fossil fuels, which are highly harmful environmentally. This paper presents a critical analysis over time of the main water splitting technologies currently in use for sustainable hydrogen production. As a result of the critical analysis, all the studied techniques have been ordered chronologically in the way that it is possible to understand how new materials have driven to new techniques, more efficient and less expensive. This allows having a complete vision of these technologies. A high level of maturity has been reached in electrolysis, while other techniques still have a long way to go, although many improvements and relevant advancements have been made over the years. The paper offers a global and comparative vision of each technology. From this, it is possible to identify the different paths where efforts are needed to make water‐based hydrogen production a mature, stable and efficient technology.

“…[21][22][23][24] However, research on hydrogen isotope exchange reactions with polymer electrolyte water electrolyzers (PEWEs) capable of high current density operation has only recently begun. [25][26][27][28] The D 2 O production method used in the Manhattan project was published in 1954, and since then many studies on industrial production methods of D 2 O have been reported. 29 There are many methods for extracting high concentrations of D 2 O from natural water, which contains approximately 140 ppm of D 2 O, such as electrolysis, distillation, deep cold separation, water-hydrogen sulde, and hydrogen-ammonia exchange reaction.…”
