Comparative sustainability assessment of a hydrogen supply network for hydrogen refueling stations in Korea – a techno-economic and lifecycle assessment perspective

Abstract

Economical and environmental sustainability of hydrogen supply routes is evaluated for hydrogen refueling stations.

Mining bitcoins with carbon capture and renewable energy for carbon neutrality across states in the USA

“…Hydrogen can be produced from renewable sources at a price range of 9.0 to 11.0 $ per kg. [72][73][74] However, additional transportation and storage costs make the overall costs more expensive. Hydrogen-powered scenarios can present a favorable pathway with reductions in technology costs for the production, storage, and transportation of hydrogen.…”

“…Hawaii followed by Rhode Island had the minimum change in BESP from their base values, as reported in the results section, at an interest rate of 20.0% as their BESP values were among the highest for all scenarios (i.e., GOP and HRPP). 61,70 The results of the sensitivity analysis for the interest rate can be seen in Fig. S13 and S14 (ESI †).…”

Life Cycle Assessment of Inland Green Hydrogen Supply Chain Networks with Current Challenges and Future Prospects

“…24 In another study, Akhtar and Liu presented a comparative feasibility study on NH 3 as a hydrogen carrier via a techno-economic analysis of transporting NH 3 from Australia to Korea and concluded that using imported green NH 3 is an economically viable alternative compared with the domestic production and transportation of hydrogen. 23,25 However, it should be noted that not all economically optimal solutions are environmentally sustainable. From an environmental perspective, hydrogen production has been thoroughly studied.…”

“…In a recent study, Aziz et al studied the transportation of hydrogen from Australia to Japan in the form of LOHC, LH 2 , and NH 3 and concluded that NH 3 is the most cost-effective solution for hydrogen transportation over long distances . In another study, Akhtar and Liu presented a comparative feasibility study on NH 3 as a hydrogen carrier via a techno-economic analysis of transporting NH 3 from Australia to Korea and concluded that using imported green NH 3 is an economically viable alternative compared with the domestic production and transportation of hydrogen. , …”

“…However, hydrogen supply chains need to be more comprehensively studied so as to develop a hydrogen storage infrastructure on a large scale. Previous studies have either considered the greenhouse gas (GHG) emissions caused by the overall operational energy demand or performed life cycle assessments (LCA) for some particular aspects of hydrogen supply chains. − In the past few years, from an environmental perspective, only a few researchers have studied the gaseous pathways of hydrogen transportation while others studied the liquid pathways, concluding the best and worst techniques. However, afterward, the goal of what to do next was left as a question for research.…”
