“…Gas-to-liquid (GTL) processes are chemical processes in which methane is converted into high-value hydrocarbon liquid products and fuels, offering market expansion and diversification for gas-producing countries [67,68]. In the GTL route, different direct and indirect technologies and operating conditions can be used for converting methane into higher-value products, subject to market demand and reservoir conditions.…”

Natural gas is the most growing fossil fuel due to its environmental advantages. For the economical transportation of natural gas to distant markets, physical (i.e., liquefaction and compression) or chemical (i.e., direct and indirect) monetisation options must be considered to reduce volume and meet the demand of different markets. Planning natural gas supply chains is a complex problem in today’s turbulent markets, especially considering the uncertainties associated with final market demand and competition with emerging renewable and hydrogen energies. This review study evaluates the latest research on mathematical programming (i.e., MILP and MINLP) as a decision-making tool for designing and planning natural gas supply chains under different planning horizons. The first part of this study assesses the status of existing natural gas infrastructures by addressing readily available natural monetisation options, quantitative tools for selecting monetisation options, and single-state and multistate natural gas supply chain optimisation models. The second part investigates hydrogen as a potential energy carrier for integration with natural gas supply chains, carbon capture utilisation, and storage technologies. This integration is foreseen to decarbonise systems, diversify the product portfolio, and fill the gap between current supply chains and the future market need of cleaner energy commodities. Since natural gas markets are turbulent and hydrogen energy has the potential to replace fossil fuels in the future, addressing stochastic conditions and demand uncertainty is vital to hedge against risks through designing a responsive supply chain in the project’s early design stages. Hence, hydrogen supply chain optimisation studies and the latest works on hydrogen–natural gas supply chain optimisation were reviewed under deterministic and stochastic conditions. Only quantitative mathematical models for supply chain optimisation, including linear and nonlinear programming models, were considered in this study to evaluate the effectiveness of each proposed approach.

“…It has been estimated that the bioethanol produced by FTS can be much less expensive than the ethanol produced by hydrolysis. Santos et al [63] conducted TEA of FTS and direct natural gas-to-methanol processes to investigate the effects of tail gas emissions and methane recycling in a compact plant footprint. The simulation results revealed that increasing the tail gas recycle ratio results in an increase in the C 5+ yield.…”

“…Additionally, the CO insertion mechanism proposes a C-C coupling reaction and the formation of alcohols [62]. Owing to the current production cost of alcoholic biofuels and their low heat of combustion, the economy of methanol production via FTS is unattractive to entrepreneurs [63]. Replacing conventional feedstocks to produce cheaper syngas for FTS can bring down the production cost of green methanol.…”

There is a growing interest in the production of biofuels and biochemicals from renewable biomass. Biomass in the form of woody and agricultural residues, municipal solid waste and other organic refuse is becoming popular as a feedstock for biofuel and biochemical production through thermochemical and biological routes. Methanol, a widely used industrial chemical, also has clean fuel properties due to its high-octane number, low flammability, low emissions and high engine performance. This paper performs a comprehensive review of different thermochemical and biological processes able to sustainably convert waste biomass to methanol. This article also evaluates the techno-economic assessment and lifecycle analysis of different processes used for methanol production. The article discusses the effects of process parameters and biomass properties on methanol production and utilization. Finally, the article concludes with recommendations on the eco-friendly aspects of methanol for use as a clean fuel and chemical derived from renewable organic bioresources.

“…In this framework, reducing CO 2 in the presence of high energy co‐reactants, such as H 2 and CH 4 , is considered thermodynamically convenient 65‐67 . In 1928, Fischer and Tropsch introduced the CO 2 conversion process in the presence of methane (CH 4 ) with Ni and Co catalysts and named it “dry reforming of methane (DRM).” 68 The shortage of chemicals during the world wars and 1970s oil crisis compelled the scientific community to use the widely abundant natural gas (CH 4 ) for chemical production via DRM and as an alternative fuel 69 . In previous decades, DRM has also been used to reduce the atmospheric CO 2 concentration.…”

Summary The conversion of CO2 to value‐added chemicals and solar fuels is a “two birds, one stone” strategy addressing two major challenges, global warming and energy crises, simultaneously. Conventionally, several approaches such as electrochemical, biochemical, and photochemical have been deployed to reduce anthropogenic CO2. However, the thermodynamic and kinetic limitations in these approaches prompted the researchers to develop more efficient CO2 utilization methods such as solar thermochemical CO2 reduction. Nevertheless, a lack of an understanding of the state‐of‐the‐art progress in CO2 utilization motivated us to present a timely comprehensive review. Herein, we summarize the traditional thermochemical‐, state‐of‐the‐art thermocatalytic, and solar thermochemical CO2 conversion with a detailed discussion of the working principles, modern techniques used, and mechanistic insights. Moreover, considering the kinetic and thermodynamic perspectives, the choice of catalysts and reaction conditions to selectively produced chemicals such as methanol, formic acid, dimethyl ether, and hydrocarbons, have been discussed. Lastly, we have highlighted the challenges and future trends for ameliorating the CO2 conversion efficiency and commercial‐scale CO2‐based solar fuel synthesis. Therefore, this review would be of substantial importance to the students and researchers to understand the CO2 conversion mechanism and to facilitate the breakthrough progress for scientific and industrial advances in carbon capture and utilization.
