Hydrogen production can be classified based on the energy source, primary reactor type, and whether or not it emits carbon dioxide. Utilizing color representation proves to be an effective means of expressing these distinctive characteristics. Among the various clean hydrogen production techniques, there has been a growing interest in turquoise hydrogen production, which involves the decomposition of methane or other fossil fuels. This method offers advantages in terms of large-scale production and cost reduction through the sale of solid- carbon byproduct. In this study, an extensive literature review was conducted to select and analyze several promising candidates for turquoise hydrogen production processes. The efficiency and economics of these processes were evaluated using stream data reported in the literature sources. The findings indicate that the levelized cost of hydrogen production (LCOH) is significantly influenced by the sales of byproducts, specifically the solid-carbon and carbon monoxide byproducts.

건식 개질 기반 청록 수소 생산을 위한 Ni-Cu 촉매 합성 최적화
최지환(Ji Hwan Choi),박상욱(Sangwook Park) 대한기계학회 2022 대한기계학회 춘추학술대회 Vol.2022 No.11
The dry reforming method is attracting great attention because it can produce hydrogen using carbon dioxide and methane, which are greenhouse gases. Although several dry reforming studies have been conducted using bimetallic alloys, additional studies are needed to ensure the high efficiency and high stability required for the industrial level. In this paper, we proceed with dry reforming by solvothermal synthesis using Nickel acetylacetonate and Copper acetylacetonate which have the same face-centered cubic(fcc) structure in nanoparticles. Using three solvents, (1) Ethanol (2) DMF(N, Ndimethylformamide) (3) Ethanol : Acetone (vol 50 : 50), we check which solvent has the highest CO2 and CH4 conversion rate and yield rate. Furthermore, by confirming that there is no change in the rate at 700°C for 24 hours, we show excellent catalytic stability when synthesizing elements with the same crystal structure.
