Summary: This study aims to use microwave plasma technology for hydrogen production from simulated seawater. By introducing methane, a gas-liquid two-phase discharge is achieved to improve hydrogen production and overcome the problem of unstable discharge. The experiment shows that the conductivity of the solution significantly affects the plasma chemical reaction, and the catalysis of chloride ions is also important. This method proves the huge potential for hydrogen production from seawater without a catalyst and provides a new reference for the subsequent hydrogen production industry.

Summary: Pyrolysis of natural gas to produce H-2 and solid carbon has low CO2 emissions but high CH4 emissions. The climate benefit of this process depends on plant location and CH4 emission reduction speed, with certain states having higher potential. Without fast action on CH4 emission mitigation, the climate benefit is minimal. A tool developed in this study can help estimate the climate impact in different scenarios and locations.

Summary: This critical review comprehensively examines the technical aspects of carbon dioxide enhanced gas recovery (CO2-EGR) for hydrogen production. The study finds that high pressure and moderate injection rates can improve EGR, while heterogeneous reservoirs tend to yield lower recovery rates. Factors such as flow rate, pressure, temperature, connate water, brine saturation, shale content, and the type of fluid phase used for injection significantly affect the molecular diffusivity of the injected gas and subsequent recovery outcomes. Simulation studies highlight the potential of injecting various gases with proper reservoir operation timing to enhance recovery and enable sustainable hydrogen production.

Summary: This study investigates the performance of a Ni-coated MoS2 membrane in the methane pyrolysis process. The membrane demonstrates excellent catalytic and separation performance due to its increased specific surface area and reduced pore size. The Ni coating attracts methane, destabilizes the C-H bond, and promotes methane deep crack, while the MoS2 membrane blocks methane and drives H proton transportation for H2 formation. This work provides guidance for bifunctional membranes in methane pyrolysis, with potential to reduce energy cost and greenhouse gas emissions.

Summary: This review summarizes recent developments and future perspectives in COx-free hydrogen production through methane pyrolysis. It discusses in detail the thermal and catalytic cracking of methane into hydrogen and carbon. Various types of solid and liquid catalysts are reviewed in terms of their performance in hydrogen selectivity, methane conversion, and deactivation. Although some pilot-scale technologies have been discussed, large-scale industrialization is hindered by challenges such as rapid solid catalyst deactivation, low-priced carbon by-product of molten catalysts, harsh reactor material conditions, and the performance of stable molten catalysts. For catalytic methane cracking in molten catalysts (salt or metal), significant advancements in catalyst development, product separation, and reactor design are still needed to commercialize methane pyrolysis for hydrogen production. To provide guidance for future research, this review specifically focuses on catalyst design, recent developments in molten salt-based methane cracking, and reactor and process design.

Summary: In recent decades, the impacts of climate change due to greenhouse gas emissions have become more severe, prompting international authorities to seek green solutions for sustainable economic development. One such solution is the reduction of fossil fuel usage in the transportation sector, with hydrogen emerging as a promising alternative due to its potential as an emission-free fuel when produced using renewable energy sources. However, there are several barriers to overcome, including production costs and the lack of distribution and storage infrastructure. This study proposes a multi-hub configuration for hydrogen production, combining on-site PV-powered electrolysis and centralized steam methane reforming. The results show that the size of the refueling station significantly affects economic performance, with larger stations offering greater benefits such as a reduction of up to 40% in the Levelized Cost of hydrogen. The synergistic effects of SMR and electrolyzer enable limited CO2 emissions per unit mass of hydrogen, and interconnecting multiple stations can further enhance environmental benefits.

Summary: This study aimed to assess the applicability of various modeling tools for representing hydrogen and methane co-production kinetics from food waste. The most suitable kinetic models were selected based on statistical comparison among different models. The results showed that the Cone model fitted hydrogen curves better, while the modified Gompertz model was the most suitable for simulating methane production.
