“…If the changes are not observed, the study shows that this form of energy generation is not as 'clean' for the environment as one might imagine. The argument emphasizes that renewable forms of energy generation, despite not directly containing carbon as a result of the process, are pollutants because they present large emissions when considering their entire manufacturing process, assembly, installation and the materials that make up their equipment 29,31 .…”

“…Only one case investigated PAFC (Zhang et al, 2021). Still, sixteen case studies do not specify the type of fuel cells in their evaluation (Sevencan and Çiftcioglu, 2013;Shimizu et al, 2020;Peppas et al, 2021). This review found fewer cases of hydrogen mono-combustion and co-combustion LCAs addressing either combined cycle or gas turbine conversion.…”

“…Tri-generation is an application of co-generation that combines a primary mover with thermally driven equipment to generate cooling (Yue et al, 2021). In this review, some LCAs considered hydrogen as energy storage, including backup power (Sevencan and Çiftcioglu, 2013;Mori et al, 2014;Stropnik et al, 2018), power generation for the electrical grid (Lunghi et al, 2004;Khan et al, 2005;Oliveira et al, 2015;Valente et al, 2015;Walker et al, 2017;Ozawa et al, 2019;Zhang et al, 2021), decentralized power generation (Suwanmanee et al, 2018), power generation for a microgrid (Spitzley et al, 2007;Mori et al, 2021), power generation for nano-grid (Rossi et al, 2020;Di Florio et al, 2021), and auxiliary power (Strazza et al, 2010). Four studies provided LCAs of hydrogen for co-generation (Melamu and von Blottnitz, 2009;Di Marcoberardino et al, 2018;Bicer and Khalid, 2020;Shimizu et al, 2020), but only one study addressed the application of tri-generation systems (Peppas et al, 2021).…”

Interest in reducing the greenhouse gas emissions from conventional power generation has increased the focus on the potential use of hydrogen to produce electricity. Numerous life-cycle assessment (LCA) studies of hydrogen-based power generation have been published. This study reviews the technological and methodological choices made in hydrogen-based power generation LCAs. A systematic review was chosen as the research method to achieve a comprehensive and minimally biased overview of hydrogen-based power generation LCAs. Relevant articles published between 2004 and 2021 were identified by searching the Scopus and Web of Science databases. Electrolysis from renewable energy resources was the most widely considered type of hydrogen production in the LCAs analyzed. Fuel cell technology was the most common conversion equipment used in hydrogen-based electricity LCAs. A significant number of scenarios examine the use of hydrogen for energy storage and co-generation purposes. Based on qualitative analysis, the methodological choices of LCAs vary between studies in terms of the functional units, allocations, system boundaries, and life-cycle impact assessment methods chosen. These discrepancies were likely to influence the value of the environmental impact results. The findings of the reviewed LCAs could provide an environmental profile of hydrogen-based electricity systems, identify hotspots, drive future research, define performance goals, and establish a baseline for their large-scale deployment.

Purpose As a first step towards a consistent framework for both individual and comparative life cycle assessment (LCA) of hydrogen energy systems, this work performs a thorough literature review on the methodological choices made in LCA studies of these energy systems. Choices affecting the LCA stages Bgoal and scope definition^, Blife cycle inventory analysis^(LCI) and Blife cycle impact assessment^(LCIA) are targeted. Methods This review considers 97 scientific papers published until December 2015, in which 509 original case studies of hydrogen energy systems are found. Based on the hydrogen production process, these case studies are classified into three technological categories: thermochemical, electrochemical and biological. A subdivision based on the scope of the studies is also applied, thus distinguishing case studies addressing hydrogen production only, hydrogen production and use in mobility and hydrogen production and use for power generation.Results and discussion Most of the hydrogen energy systems apply cradle/gate-to-gate boundaries, while cradle/gate-tograve boundaries are found mainly for hydrogen use in mobility. The functional unit is usually mass-or energybased for cradle/gate-to-gate studies and travelled distance for cradle/gate-to-grave studies. Multifunctionality is addressed mainly through system expansion and, to a lesser extent, physical allocation. Regarding LCI, scientific literature and life cycle databases are the main data sources for both background and foreground processes. Regarding LCIA, the most common impact categories evaluated are global warming and energy consumption through the IPCC and VDI methods, respectively. The remaining indicators are often evaluated using the CML family methods. The level of agreement of these trends with the available FC-HyGuide guidelines for LCA of hydrogen energy systems depends on the specific methodological aspect considered. Conclusions This review on LCA of hydrogen energy systems succeeded in finding relevant trends in methodological choices, especially regarding the frequent use of system expansion and secondary data under production-oriented attributional approaches. These trends are expected to facilitate methodological decision making in future LCA studies of hydrogen energy systems. Furthermore, this review may provide a basis for the definition of a methodological framework to harmonise the LCA results of hydrogen available so far in the literature.
