“…Because hydrogen is a sustainable energy source and does not emit greenhouse gases, it is attracting attention as an eco-friendly energy worldwide [1][2][3][4][5]. Global hydrogen energy demand will increase rapidly from 8 EJ in 2015 to 78 EJ in 2050 and is expected to account for 18% of the total energy demand [6].…”

South Korea has a plan to realize a hydrogen economy, and it is essential to establish a main hydrogen pipeline for hydrogen transport. This study develops a cost estimation model applicable to the construction of hydrogen pipelines and conducts an economic analysis to evaluate various scenarios for hydrogen pipeline construction. As a result, the cost of modifying an existing natural gas to a hydrogen pipeline is the lowest, however, there are issues with the safety of the modified hydrogen pipes from natural gas and the necessity of the existing natural gas pipelines. In the case of a short-distance hydrogen pipeline, the cost is about 1.8 times that of the existing natural gas pipeline modification, but it is considered a transitional scenario before the construction of the main hydrogen pipeline nationwide. Lastly, in the case of long-distance main hydrogen pipeline construction, it takes about 3.7 times as much cost as natural gas pipeline modification, however it has the advantage of being the ultimate hydrogen pipeline network. In this study, various hydrogen pipeline establishment scenarios ware compared. These results are expected to be utilized to establish plans for building hydrogen pipelines and to evaluate their economic feasibility.

“…Planar SOCs (PSOCs) and tubular SOCs (TSOCs) are two prevalent structures of SOCs. PSOCs have the advantages of easy manufacturing and large power density, but the sealing of PSOCs is troublesome due to the high temperature and the thermal expansion mismatch among ceramic and metallic materials [1,2]. TSOCs are robust and easy for sealing but are limited by the power density as well as fabrication method [3,4].…”

In direct methanol fuel cells (DMFC), methanol crossover is a major issue which has reduced the performance of polymer electrolyte membrane (PEM) for energy generation. In this study, graphene oxide (GO) and conductive polyaniline decorated GO (PANI-GO) were used as additives in fabrication of sulfonated poly(ether ether ketone) (SPEEK) nanocomposite PEM membrane to reduce methanol crossover. PANI-GO was synthesized by in situ polymerization method and the formation of PANI coated GO nanostructures was confirmed by surface morphology and crystallinity analysis. The membrane morphology and topography analysis confirmed that GO and PANI-GO were well dispersed on the surface of SPEEK membrane. 0.1 wt% PANI-GO modified SPEEK nanocomposite membrane exhibited the highest water uptake and ion exchange capacity of 40% and 1.74 meq g À1 , respectively. The oxidative stability of the nanocomposite membranes also improved. Lower methanol permeability of 4.33 Â 10 À7 cm À2 S À1 was noticed for 0.1 wt% PANI-GO modified SPEEK membrane. PANI-GO modified SPEEK membrane enhanced the proton conductivity, which was due to the existence of acidic and hydrophilic group present in PANI and GO. PANI-GO modified SPEEK membrane held higher selectivity of 1.94 Â 10 4 S cm À3 s À1 . Overall, these studies revealed that PANI-GO modified SPEEK membrane is a potential material for DMFC applications.
