“…Another technique in carbon dioxide capture is that carbon dioxide from any gas mixture can be separated by cooling and condensation [ 45 ]. Cryogenic separation allows direct production of liquid carbon dioxide and is also suitable for long distance transport [ 46 ]. The disadvantages are that the amount of energy required to provide cooling is high for this proposed process, and some components such as water must be taken during the process to prevent the gas flow from cooling the blocks.…”

With the synthesis of ammonia with chemical methods, global carbon emission is the biggest threat to global warming. However, the dependence of the agricultural industry on ammonia production brings with it various research studies in order to minimize the carbon emission that occurs with the ammonia synthesis process. In order to completely eliminate the carbon emissions from ammonia production, both the hydrogen and the energy needed for the operation of the process must be obtained from renewable sources. Thus, hydrogen can be produced commercially in a variety of ways. Many processes are discussed to accompany the Haber Bosch process in ammonia production as potential competitors. In addition to parameters such as temperature and pressure, various plasma catalysts are being studied to accelerate the ammonia production reaction. In this study, various alternative processes for the capture, storage and complete removal of carbon gas released during the current ammonia production are evaluated and the current conditions related to the applicability of these processes are discussed.In addition, it has been discussed under which conditions it is possible to produce larger capacities as needed in the processes studied in order to reduce carbon gas emissions during ammonia production in order to provide raw material source for fertilizer production and energy sector. However, if the hydrogen gas required for ammonia production is produced using a solid oxide electrolysis cell, the reduction in the energy requirement of the process and in this case the reduction of energy costs shows that it will play an important role in determining the method to be used for ammonia production. In addition, it is predicted that working at lower temperature (<400 C) and pressure (<10 bar) values in existing ammonia production technologies, despite increasing possible energy costs, will significantly reduce process operating costs.

“…The results indicate that cryogenic-based technology provides 97 % purity of CH 4 with less specific energy consumption. Spitoni et al [39] compared the cryogenic process with other upgrading technologies and presented a novel approach for an efficient cryogenic process with CO 2 cold recovery. The method provides a lower specific energy consumption than state-of-the-art upgrading technologies, resulting in a saving of 22 % in terms of operation cost compared to conventional upgrading methodologies.…”

Biogas requires specific processing in terms of upgradation to remove acid gas contents, making it a profitable fuel with higher energy content. This is conventionally attained through physical or chemical absorption due to the higher selectivity towards CO2 and H2S. The conventional processing technology impacts the process with higher energy content for solvent regeneration, solvent loss causing a threat to the environment with its toxicity, and damaging the equipment by corrosion. In this view, ionic liquids (ILs) emerged as potential candidates providing a favorable facet in terms of both processing and ecological aspects. Hence, herein the potential of IL and deep eutectic solvent (DES) in comparison to the conventional solvents and technologies used for biogas upgrading based on process system engineering perspective that showcases techno‐economic, energy‐economic, and environmental aspects and opportunities that may lead towards establishing sustainable and effective processing of biogas is shown and a comprehensive review on the opportunities, prospects, and challenges to make IL and DES as future solvent for biogas upgrading on the commercial scale is provided.

The energy supply in the world needs to change from fossil fuels to renewable alternatives. Biogas is such a renewable alternative, and there is potential to increase the biogas production in the world. In recent decades, many countries have increasingly been upgrading biogas to vehicle fuel. In the last few years, the interest has also increased in liquefying biogas for heavier transports. Biogas can also be a raw material for other fuels by gasifying the biogas, for example Fischer-Tropsch fuels, methanol, dimethyl ether and hydrogen. This study provides an overview of vehicle fuels that can be produced from biogas, their technological maturity and their respective potentials as substitutes for fossil fuels in the transport system. A common factor for all of them is that they are most often produced from fossil fuels. Compressed and liquefied methane are the only fuels being commercially produced using biogas. The other fuels all have strengths that both compressed and liquefied methane lack, for example the possibility of emission-free fuel cell vehicles. However, they are all less mature technologies than compressed and liquefied methane. The greatest short-term potential is thus for expanded use of biogas as compressed and liquefied biomethane.
