“…One study claims that CO 2 footprint of renewable electricity must be sufficiently low, e.g. in case of hydrogen fuel a threshold is 190 kgCO 2 eq/MW h el , while in case of methane fuel it is 113 kgCO 2 eq/MW h el [50]. Energy mix in none of countries has so low CO 2 footprint today while achieving so low values by employing renewable is globally not feasible by 2030.…”

“…In this analysis, attention is given to the capability of chemistry to become the prominent solution in storing intermittent renewable energy in batteries or molecules, such as hydrogen and methane. Reiter and Lindorfer [16] introduce the potential of power-to-gas as a tool for energy storage, which is the prominent method to store molecules. On this subject, due to its importance, a specific chapter is provided below.…”

Abstract:The electricity sector is among the main contributors to carbon emissions. This sector has the potential to reduce its carbon emissions through producing electric energy from zero-emitting facilities and optimizing consumption to better accommodate low-carbon emissions. The use of hydrogen combined with smart grids, as analyzed in this manuscript, can substantially contribute to climate change mitigation.

“…In mobility applications, hydrogen as a fuel in vehicles with internal combustion engine is considered in less than 10 % of the case studies. Regarding stationary application, 3 out of 27 cases use hydrogen for methanation via the Sabatier reaction (Reiter and Lindorfer 2015), while the remaining cases (24) address power production: 2 cases using molten-carbonate fuel cell technology (Lunghi et al 2004), 15 using PEMFC technology, and 7 using a gas turbine. Pehnt (2003) also considers solid oxide fuel cells but without using hydrogen as the fuel.…”

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.
