“…Between one and two orders of magnitude higher values of AP were found for the thermochemical treatment or process gases derived from MSW [39]. The gasification of bio-oil derived from the pyrolysis of sawmill waste biomass account for 4.2 × 10 −3 molH + eq/kgH2, mostly due to the sulfur emission associated with the production and use of the NG used in the reforming process and to the acid gases released during pyrolysis [40]. Lower emissions (4.0 × 10 −4 molH + eq/kgH2) were calculated in relation to the reforming of the biogas produced in an anaerobic digestion plant operating with biological wastes.…”

“…The authors report that more than 50% of the impact is related to the reforming process of pyrolysis oil, due to the use of NG. Coupling steam reforming with the anaerobic digestion of biowaste led to a negative impact equal to −1.8 × 10 −5 kg Sbeq /kg H2 , thanks to the use of digestate that replaces fertilizer production [40]. These latter results are the only one referring to gate-to-gate system boundaries, while in all the others, it was considered a cradle-to-gate.…”

“…Pyrolysis, gasification and integrated pyrolysis with the gasification of MSW resulted in 3 × 10 −3 kg Cueq /kg H2 , 4 × 10 −3 kg Cueq /kg H2 and 5 × 10 −3 kg Cueq /kg H2, respectively, with reactors heated through NG and electric energy coming from a thermoelectric power plant [39]. Integrated pyrolysis and gasification were also studied by Arfan et al [40] using waste biomass derived from a sawmill plant, resulting in 1.1 × 10 −5 kg Sbeq /kg H2 . The authors report that more than 50% of the impact is related to the reforming process of pyrolysis oil, due to the use of NG.…”

“…Comparing the sole gasification with an integrated pyrolysis + gasification process, the latter scheme can drive to a GWP reduction of between 5% and 19%. GHG emissions for biomass gasification were found to be equal to 5.3 kg CO2eq /kg H2 (−15.4 kg CO2eq /kg H2 when coupled with CCS) [28], 1.1 kg CO2eq /kg H2 (−13.8 kg CO2eq /kg H2 with CCS) [32] and 1.5 kg CO2eq /kg H2 [40], respectively, when using southern yellow pine, poplar wood, or bio-oil coming from the pyrolysis of sawmill by-products. The latter case is the only that refers to a gate-to-gate approach, not including the energy and material consumption for three cases of cultivation and harvesting, since the feedstock is considered as a by-product of a different system.…”

“…Lower emissions (4.0 × 10 −4 molH + eq /kg H2 ) were calculated in relation to the reforming of the biogas produced in an anaerobic digestion plant operating with biological wastes. In fact, the possible application of the digestate material as agricultural soil improver avoids the emission of acid that would have been otherwise generated for the production of fertilizers [40]. The following Figure 5 shows the trend in acidification potential for all the different technologies.…”

In light of growing concerns regarding greenhouse gas emissions and the increasingly severe impacts of climate change, the global situation demands immediate action to transition towards sustainable energy solutions. In this sense, hydrogen could play a fundamental role in the energy transition, offering a potential clean and versatile energy carrier. This paper reviews the recent results of Life Cycle Assessment studies of different hydrogen production pathways, which are trying to define the routes that can guarantee the least environmental burdens. Steam methane reforming was considered as the benchmark for Global Warming Potential, with an average emission of 11 kgCO2eq/kgH2. Hydrogen produced from water electrolysis powered by renewable energy (green H2) or nuclear energy (pink H2) showed the average lowest impacts, with mean values of 2.02 kgCO2eq/kgH2 and 0.41 kgCO2eq/kgH2, respectively. The use of grid electricity to power the electrolyzer (yellow H2) raised the mean carbon footprint up to 17.2 kgCO2eq/kgH2, with a peak of 41.4 kgCO2eq/kgH2 in the case of countries with low renewable energy production. Waste pyrolysis and/or gasification presented average emissions three times higher than steam methane reforming, while the recourse to residual biomass and biowaste significantly lowered greenhouse gas emissions. The acidification potential presents comparable results for all the technologies studied, except for biomass gasification which showed significantly higher and more scattered values. Regarding the abiotic depletion potential (mineral), the main issue is the lack of an established recycling strategy, especially for electrolysis technologies that hamper the inclusion of the End of Life stage in LCA computation. Whenever data were available, hotspots for each hydrogen production process were identified.

In the pursuit of sustainable energy solutions, hydrogen emerges as a promising candidate for decarbonization. The United States has the potential to sell wind energy at a record‐low price of 2.5 cents/kWh, making hydrogen production electricity up to four times cheaper than natural gas. Hydrogen's appeal stems from its highly exothermic reaction with oxygen, producing only water as a byproduct. With an energy content equivalent to 2.4 kg of methane or 2.8 kg of gasoline per kilogram, hydrogen boasts a superior energy‐to‐weight ratio compared to fossil fuels. However, its energy‐to‐volume ratio, exemplified by liquid hydrogen's 8.5 MJ.L−1 versus gasoline's 32.6 MJ.L−1, presents a challenge, requiring a larger volume for equivalent energy. In addition, this review employs life cycle assessment (LCA) to evaluate hydrogen's full life cycle, including production, storage, and utilization. Through an examination of LCA methodologies and principles, the review underscores its importance in measuring hydrogen's environmental sustainability and energy consumption. Key findings reveal diverse hydrogen production pathways, such as blue, green, and purple hydrogen, offering a nuanced understanding of their life cycle inventories. The impact assessment of hydrogen production is explored, supported by case studies illustrating environmental implications. Comparative LCA analysis across different pathways provides crucial insights for decision‐making, shaping environmental and sustainability considerations. Ultimately, the review emphasizes LCA's pivotal role in guiding the hydrogen economy toward a low‐carbon future, positioning hydrogen as a versatile energy carrier with significant potential.This article is categorized under: Emerging Technologies > Hydrogen and Fuel Cells
