Green hydrogen has become the key to social low-carbon transformation and is fully linked to zero carbon emissions. The carbon emissions trading market is a policy tool used to control carbon emissions using a market-oriented mechanism. Building a modular carbon trading center for the hydrogen energy industry would greatly promote the meeting of climate targets. Based on this, a “green hydrogen market—national carbon trading market–electricity market” coupling mechanism is designed. Then, the “green hydrogen market—national carbon trading market–electricity market” mechanism is modeled and simulated using system dynamics. The results are as follows: First, coupling between the green hydrogen market, carbon trading market and electricity market can be realized through green hydrogen certification and carbon quota trading. It is found that the coupling model is feasible through simulation. Second, simulation of the basic scenario finds that multiple-market coupling can stimulate an increase in carbon price, the control of thermal power generation and an increase in green hydrogen production. Finally, the proportion of the green hydrogen certification, the elimination mechanism of outdated units and the quota auction mechanism will help to form a carbon pricing mechanism. This study enriches the green hydrogen trading model and establishes a multiple-market linkage mechanism.

“…Moreover, a few studies have experimentally proven that hydrogen production from coal and biomass was a long-term and viable way to solve energy crises and environmental pollution. 6,7 Among the hydrogen production processes, gasification hydrogen production (GHP) and anaerobic hydrogen fermentation (AHF) were recognized as two economically effective approaches, providing the higher potential to become competitive on a large scale in the near future. However, GHP technology is superior to AHF technology in terms of hydrogen yield and production rate.…”

Hydrogen (H 2 ) production from coal and biomass gasification was considered a long-term and viable way to solve energy crises and global warming. Tar, generated as a hazardous byproduct, limited its large-scale applications by clogging and corroding gasification equipment. Although catalytic steam reforming technology was used to convert tar into H 2 , catalyst deactivation restricted its applicability. A novel nanocatalyst was first synthesized by the modified sol−gel method using activated biochar as the support, nickel (Ni) as the active component, and cobalt (Co) as the promoter for converting tar into H 2 . The results indicated that a high H 2 yield of 263.84 g H 2 / kg TMCs (Tar Model Compounds) and TMC conversion of almost 100% were obtained over 6% Ni−4% Co/char, with more than 30% increase in hydrogen yield compared to traditional catalysts. Moreover, 6% Ni−4% Co/char exhibited excellent resistance to carbon deposition by removing the nucleation sites for graphite formation, forming stable Ni−Co alloy, and promoting the char gasification reaction; resistance to oxidation deactivation due to the high oxygen affinity of Co and reduction of the oxidized nickel by H 2 and CO; resistance to sintering deactivation by strengthened interaction between Ni and Co, high specific surface area (920.61 m 2 /g), and high dispersion (7.3%) of Ni nanoparticles. This work provided a novel nanocatalyst with significant potential for long-term practical applications in the in situ conversion of tar into H 2 during steam reforming.

“…Like biomass in general, wood biomass contains lignocellulosic content such as cellulose, hemicellulose, and lignin [1][2][3]. These contents commonly consist of some abundant elements such as carbon, hydrogen, and oxygen, as well as some less abundant elements such as nitrogen and sulfur [4][5][6].…”

The plasma-assisted pyrolysis process is a powerful treatment for converting wood biomass to graphitic carbon. In order to make this process more precise and effective in time, the rate of graphitization data is needed, especially for predicting the effective time of treatment. In this study, numerical analysis is conducted to predict the rate of graphitization. An explicit finite difference method is applied for the numerical analysis. Some initial parameters used are the wood thickness (5 mm), coefficient of diffusivity (0.082 mm2/s), input plasma temperature (4,000 C), initial wood temperature (35 C), and room temperature (27 C). The analysis was conducted with a variation of time differences of 1 s, 2 s, 3 s, 4 s, and 5 s. The assumption used in this analysis is that the minimum temperature for graphitic carbon conversion is 2,000 C. The result of this study is the values of graphitization rates and exposure times summarized in TABLE 1. Therefore, this numerical analysis can successfully be used to predict the rate of graphitization and plasma exposure time for different wood biomass thicknesses.
