There is a global need to increase the production of alternative sources of energy due to many issues related to conventional sources, such as environmental degradation or energy security. In this paper, decentralized liquefied natural gas production is analyzed. Liquefied natural gas, according to the analysis, can be considered a viable alternative even for decentralized applications Design and economic analysis of a small-scale biogas LNG plan together with the necessary technology and economic evaluation are presented in the paper. The results show that a project of the proposed size (EUR 3 million) offers a relatively good profitability level. Specifically, the net present value of the project is mostly positive (around EUR 0.1 million up to EUR 0.8 million). Therefore, based on the research, small LNG plants operating across the continent can be recommended for the processing of local sources of biogas.

Introduction: the analysis of the main areas of energy transition (energie wende) from fossil fuels and nuclear power generation to renewable sources of energy has identified the following four key problems: electric power shortage; ageing of power generation facilities; insufficient infrastructure; growing demand for gas fuel. In Russia, distributed small-scale power generation facilities serve those consumers who have no access to centralized power supply or network channels of regular power generation. A combination of versatile approaches to electric power generation should be applied in the course of designing a specific energy generation facility in this context.Methods: the research project represents an analysis of the works written by the leading Russian and foreign researchers specializing on power engineering, namely, energy supply to consumers. The expert assessment method has identified the niches which are best fitted by gas turbine facilities. Computerized and simulation modeling techniques were used to perform the analytical and statistical processing of the project findings.Results and discussion: the trend for the structural improvement of small-scale liquefied natural gas facilities has been identified in the course of the research. The author has substantiated development of systems for power supply to smallcapacity liquefied natural gas production facilities. The proposed gas turbine GTU-2U is designated for generation of electric energy, if in operation as a standalone facility as part of a centralized heating and power plant in the standalone mode of operation, or in case of concurrent operation along with an energy generation system within the framework of distributed small capacity networks. The co-authors have substantiated the unit’s practical application and identified the GTU-2U distribution market both in Russia and abroad: small capacity distributed power generation industry and power supply to small-capacity liquefied natural gas production facilities. The latter is a relatively new market which is in the process of proactive development both in mature and developing economies. This power supply pattern will enable to monetize gas deposits, located far from pipelines and to supply gas to hard-to-access regions.Conclusion: the key trends in the development of the contemporary power generation industry are considered in the article. Gas turbine unit GTU-2U has been designed. This unit is capable of generating power both as a standalone facility, as a component of a centralized heating and power plant in the standalone mode of operation, or in case of concurrent operation along with an energy generation system. Its strengths substantiate its practical application both in the Russian and international power generation markets.

In the last years, the increased demand of the energy market has led to the increasing penetration of renewable energies in order to achieve the primary energy supply. However, simultaneously natural gas still plays a key role in the energy market, mainly as gaseous fuel for stationary energy generation, but also as liquefied fuel, as an alternative to the diesel fuel, in vehicular applications. Liquefied Natural Gas (LNG) is currently produced in large plants directly located at the extraction sites. In this study, the idea of realizing plug & play solutions to produce LNG directly at vehicle’s filling stations has been investigated. A novel process of LNG production for filling stations has been analyzed, consisting in a single stage Joule-Thompson isenthalpic expansion process, with intercooled compression. Furthermore, the presented layout has been developed with the purpose of optimizing the energy consumption of the plant, obtaining moderately pressurized LNG. With the aim of investigating the feasibility of this novel LNG generation process, a thermodynamic analysis has been carried out and presented in this study. Moreover, the minimization of energy consumption has been investigated with a parametric analysis, in order to optimize the LNG production and to maximize the efficiency of the process. Furthermore, novel performance indicators have been defined, in order to account the efficiency of the LNG production process. Results of the optimization analysis show that, with the proposed layout, an energy consumption equal to about 1.9 MJ/kg of produced LNG can be achieved.

Subject Plans for energy security and diversification. Significance Because of regional insecurity and political divisions, liquefied natural gas (LNG) is the best option for Jordan as its primary energy source. However, renewables can also make a significant contribution to diversified domestic energy production. Impacts Jordan will benefit from the wider uptake of renewables across the Middle East, particularly solar power. A lack of significant oil or gas production may encourage electrification in transport. Deterioration in Israeli-Palestinian relations could undermine the Leviathan gas deal.

The Impact

Methane is the second highest contributor to the greenhouse effect. Its global warming potential is 37 times that of CO2. Flaring-associated natural gas from remote oil reservoirs is currently the only economical alternative. Gas-to-liquid (GtL) technologies first convert natural gas into syngas, then it into liquids such as methanol, Fischer–Tropsch fuels or dimethyl ether. However, studies on the influence of feedstock composition are sparse, which also poses technical design challenges. Here, we examine the techno-economic analysis of a micro-refinery unit (MRU) that partially oxidizes methane-rich feedstocks and polymerizes the syngas formed via Fischer–Tropsch reaction. We consider three methane-containing waste gases: natural gas, biogas, and landfill gas. The FT fuel selling price is critical for the economy of the unit. A Monte Carlo simulation assesses the influence of the composition on the final product quantity as well as on the capital and operative expenses. The Aspen Plus simulation and Python calculate the net present value and payback time of the MRU for different price scenarios. The CO2 content in biogas and landfill gas limit the CO/H2 ratio to 1.3 and 0.9, respectively, which increases the olefins content of the final product. Compressors are the main source of capital cost while the labor cost represents 20–25% of the variable cost. An analysis of the impact of the plant dimension demonstrated that the higher number represents a favorable business model for this unit. A minimal production of 7,300,000 kg y−1 is required for MRU to have a positive net present value after 10 years when natural gas is the feedstock.

The COVID-19 pandemic appeared in the midst of developing the European Green Deal, the most ambitious project to decarbonise the EU’s economy to date. Among other issues, the project highlighted the challenges connected to the long-term role of natural gas as a fossil fuel in the European economy. Moreover, the changes to the gas architecture caused by the development of new import infrastructure (especially Nord Stream and its extension, which is currently under construction) put additional pressure on the transit countries, mainly of which are linked to the Brotherhood pipeline. These have been strong supporters of natural gas utilisation and harsh critics of new pipelines that circumvent their territories, as they consider energy transit to be an important part of their energy sectors. This research examines the political discourse on gas transit in Slovakia and Ukraine in order to identify the main arguments connected to these positions. The paper examines a total of 233 textual units from both countries for the period 2014–2018. It concludes that, while Ukraine sees transit predominantly through the lens of cooperation with the EU and other actors, the Slovak political discourse considers gas transit in terms of energy security and the availability of gas for the national economy.
