“…13 studies, consisting of 10 peer-reviewed papers (Koroneos et al, 2004;Granovskii et al, 2006;Granovskii et al, 2007;Lombardi et al, 2011;Ozbilen et al, 2011;Cetinkaya et al, 2012;Pereira and Coelho, 2013;Reiter and Lindorfer, 2015;Suleman et al, 2015;Schmidt Rivera et al, 2018) and three reports on LCAs (Simons et al, 2011;Suleman, 2014;Lundberg, 2019) on PV-powered hydrogen production technologies, were selected for this review and the subsequent GWP harmonization process. The studies were published between 2004 and 2019.…”

“…The majority of reviewed studies could not be harmonized. A total number of 34 case studies was pre-selected, 13 of which could be harmonized (Cetinkaya et al, 2012;Granovskii et al, 2006;Granovskii et al, 2007;Koroneos et al, 2004;Lombardi et al, 2011;Lundberg, 2019;Ozbilen et al, 2011;Pereira and Coelho, 2013;Reiter and Lindorfer, 2015;Simons et al, 2011;Suleman et al, 2015;Suleman, 2014;Schmidt Rivera et al, 2018).…”

“…From a literature study, it is found that almost all LCA studies on hydrogen production by means of electrolysis report the global warming potential (GWP) in the following unit: kg CO 2 -eq/kg H 2 . The biggest impact on the GWP is caused by the power supply of hydrogen production (Koroneos et al, 2004;Granovskii et al, 2006;Granovskii et al, 2007;Lombardi et al, 2011;Ozbilen et al, 2011;Simons et al, 2011;Cetinkaya et al, 2012;Pereira and Coelho, 2013;Suleman, 2014;Reiter and Lindorfer, 2015;Suleman et al, 2015;Schmidt Rivera et al, 2018;Lundberg, 2019). The reviews of Bhandari et al (Bhandari et al, 2014), Valente et al (Valente et al, 2017) and Mehmeti et al (Mehmeti et al, 2018) demonstrate how the GWP results change depending on the electricity source used.…”

“…In this manner, a more understandable and comparable framework can be developed. To achieve this goal, 13 LCA studies (Koroneos et al, 2004;Granovskii et al, 2006;Granovskii et al, 2007;Lombardi et al, 2011;Ozbilen et al, 2011;Simons et al, 2011;Cetinkaya et al, 2012;Pereira and Coelho, 2013;Suleman, 2014;Reiter and Lindorfer, 2015;Suleman et al, 2015;Schmidt Rivera et al, 2018;Lundberg, 2019) on PV-powered hydrogen production technologies were selected, analyzed and harmonized. As a reference for the harmonization framework, a guidance document published by the European Union and Fraunhofer ISE with the framework of recommendations for LCA on hydrogen production was applied (Masoni and Zamagni, 2011;Lozanovski et al, 2013).…”

Review and Harmonization of the Life-Cycle Global Warming Impact of PV-Powered Hydrogen Production by Electrolysis

et al. 2021

This work presents a review of life-cycle assessment (LCA) studies of hydrogen electrolysis using power from photovoltaic (PV) systems. The paper discusses the assumptions, strengths and weaknesses of 13 LCA studies and identifies the causes of the environmental impact. Differences in assumptions of system boundaries, system sizes, evaluation methods, and functional units make it challenging to directly compare the Global Warming Potential (GWP) resulting from different studies. To simplify this process, 13 selected LCA studies on PV-powered hydrogen production have been harmonized following a consistent framework described by this paper. The harmonized GWP values vary from 0.7 to 6.6 kg CO2-eq/kg H2 which can be considered a wide range. The maximum absolute difference between the original and harmonized GWP results of a study is 1.5 kg CO2-eq/kg H2. Yet even the highest GWP of this study is over four times lower than the GWP of grid-powered electrolysis in Germany. Due to the lack of transparency of most LCAs included in this review, full identification of the sources of discrepancies (methods applied, assumed production conditions) is not possible. Overall it can be concluded that the environmental impact of the electrolytic hydrogen production process is mainly caused by the GWP of the electricity supply. For future environmental impact studies on hydrogen production systems, it is highly recommended to 1) divide the whole system into well-defined subsystems using compression as the final stage of the LCA and 2) to provide energy inputs/GWP results for the different subsystems.

“…Hydrogen possesses a gravimetric energy density of~120 MJ kg −1 , is abundant, and has an environmentally friendly nature, as it is derived from renewable resources, making it more economically convenient in comparison to many other fuels [1,2]. It can also replace conventional fuels in industrial and home applications, either to offer high temperatures upon burning and/or to catalyze hydro-cracking in petrochemical industry [3,4].…”

Hydrogen Storage in Untreated/Ammonia-Treated and Transition Metal-Decorated (Pt, Pd, Ni, Rh, Ir and Ru) Activated Carbons

Hydrogen storage may be the bottle neck in hydrogen economy, where hydrogen spillover is in dispute as an effective mechanism. In this context, activated carbon (AC) was doped with nitrogen by using ammonia gas, and was further decorated with platinum, palladium, nickel, rhodium, iridium and ruthenium, via an ultrasound-assisted impregnation method, with average particle sizes of around 74, 60, 78, 61, 67 and 38 nm, respectively. The hydrogen storage was compared, before and after modification at both ambient and cryogenic temperatures, for exploring the spillover effect, induced by the decorating transition metals. Ammonia treatment improved hydrogen storage at both 298 K and 77 K, for the samples, where this enhancement was more remarkable at 298 K. Nevertheless, metal decoration reduced the hydrogen uptake of AC for all of the decorated samples other than palladium at cryogenic temperature, but improved it remarkably, especially for iridium and palladium, at room temperature. This observation suggested that metal decoration’s counter effect overcomes hydrogen spillover at cryogenic temperatures, while the opposite takes place at ambient temperature.
