“…It was reported that global warming potential varied from -85 kg CO 2 eq/kg H 2 to 110 kg CO 2 eq/kg H 2 Reaño, 2020 The study compared alkali water electrolysis, gasification and dark fermentation for hydrogen production. The dark fermentation pathway was recorded as the most efficient process based on a net energy ratio of 1.25 and global warming potential as 46 kg CO 2 eq/kg of H 2 Sadeghi et al, 2020 The total greenhouse gas emissions were 10.28, 11.59, 3.08 and 2.06 kg CO 2 eq for 1 kg H 2 for steam methane reforming, coal gasification, photovoltaic electrolysis and solar thermal electrolysis, respectively Sako et al, 2021 This study compared the production of battery-assisted and conventional hydrogen production systems. It concluded that the battery-assisted hydrogen production had lower greenhouse gas emissions (0.15 to 0.3 kg CO 2 eq/kWh) compared to the conventional hydrogen production process (0.9 to 1.08 kg CO 2 eq/kWh) Sanchez, Ruiz et al 2021 The use of sugarcane press-mud, as a biomass source, had environmental benefits in comparison to the use of anhydrous ethanol from sugarcane molasses as feedstock for power generation using hydrogen as an energy vector.…”

Dihydrogen (H2), commonly named ‘hydrogen’, is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ‘affordable and clean energy’ of the United Nations. Here we review hydrogen production and life cycle analysis, hydrogen geological storage and hydrogen utilisation. Hydrogen is produced by water electrolysis, steam methane reforming, methane pyrolysis and coal gasification. We compare the environmental impact of hydrogen production routes by life cycle analysis. Hydrogen is used in power systems, transportation, hydrocarbon and ammonia production, and metallugical industries. Overall, combining electrolysis-generated hydrogen with hydrogen storage in underground porous media such as geological reservoirs and salt caverns is well suited for shifting excess off-peak energy to meet dispatchable on-peak demand.

“…Exergy analysis is discussed elsewhere for many applications (Sato 2005;Kotas 2012;Moran et al 2018;Dincer and Rosen 2021). The present author has performed exergy assessments in a wide variety of areas: fossil fuel processes (Sadeghi et al 2020;Khoshgoftar Manesh et al 2021), hydrogen production (Lescisin et al 2020Sadeghi et al 2020), electricity generation via fuel cells, gas turbines and Rankine cycles (Hossein Karimi et al 2020), polygeneration (Bolt et al 2021, integrated energy systems (Keshavarzzadeh et al 2020), cooling and district cooling (Anderson et al 2021;Bolt et al 2021), energy storage (Anderson et al 2021), desalination (Keshavarzzadeh et al 2020), solar energy (Keshavarzzadeh et al 2020;Sadeghi et al 2020), bioenergy (Hossein Karimi et al 2020, and countries and their economic sectors (Hossain et al 2020;Rosen 2013).…”

Although energy is conventionally examined when studying thermodynamic flows and balances for the Earth and its systems, the planet does not consume energy as its energy inflows and outflows are in balance. Similarly, energy is conserved for systems on the Earth. The Earth does, however, consume exergy and generate entropy, and it is insightful to examine the thermodynamics of the Earth in terms of exergy, or the related quantity entropy. These perspectives are considered here for the Earth and its main systems: the biosphere, people and civilization. The work provides an enhanced understanding of the type, location and causes of thermodynamic losses for the Earth as well as its main systems and subsystems, and of the connections and relations between the Earth and its biosphere, as well as civilization and people. It is observed for the year 2019 that civilization uses exergy to create many products and services and that the exergy consumption rate of the Earth's biosphere is approximately five times larger than that of civilization and 100 times larger than that of people as individuals. Also, the solar exergy rate provides the Earth with a very large exergy input rate, about 10,000 times greater than the needs.

“…Life cycle assessment (LCA) is an effective methodology for analyses (Graedel and Allenby 2010 ). LCA has been applied extensively to a broad range of activities (Ben-Alon et al 2019 ; Lodato et al 2020 ; Lu and Halog 2020 ), including energy processes (Sadeghi et al 2020 ; Mendecka et al 2020 ) and communities (Karunathilake et al 2019 ).…”

Energy sustainability is a key consideration for anthropogenic activity and the development of societies, and more broadly, civilization. In this article, energy sustainability is described and examined, as are methods and technologies that can help enhance it. As a key component of sustainability, the significance and importance of energy sustainability becomes clear. Requirements to enhance energy sustainability are described, including low environmental and ecological impacts, sustainable energy resources and complementary energy carriers, high efficiencies, and various other factors. The latter are predominantly non-technical, and include living standards, societal acceptability and equity. The outcomes and results are anticipated to inform and educate about energy sustainability, to provide an impetus to greater energy sustainability.
