This paper analyzes the possible role of liquefied natural gas (LNG) in the region in reducing carbon dioxide (CO2) emissions by replacing a certain part of solid fossil fuels. Increasing natural gas consumption, declining North Sea natural gas reserves and increased natural gas production costs in Europe combined have created new opportunities for LNG in Europe. The Energy Strategy of Croatia is focused on intensifying the transit position for natural gas that could establish Croatia as a primary LNG market for countries from the region, which shows that the Energy Strategy supports LNG. Concerning LNG’s introduction into the regional gas market, this paper analyses the possibility of establishing a regional gas hub. The region in this paper includes the following countries: Croatia, Serbia, Bosnia and Herzegovina, Hungary, Slovenia, and North Macedonia. On the other hand, the observed markets are not organized and sufficiently liquid, which is a crucial precondition for hub establishment. In order to decrease the region’s dependence on pipeline natural gas, it is necessary to construct gas interconnections between Croatia – Serbia, Croatia – Bosnia and Herzegovina and Serbia – North Macedonia. With the mentioned interconnections, the region could achieve greater security of natural gas supply. This paper discusses the possibility of utilizing the full capacity of a LNG terminal as a source of natural gas supply for the purpose of replacing solid fossil fuels in the region’s primary energy consumption. By replacing solid fossil fuels with natural gas, it is possible to achieve significant savings on CO2 emissions, which contributes towards a green and sustainable future.

The drastic increase in domestic production of natural gas due to the fracking boom prompted efforts to develop a robust infrastructure in the U.S. to export natural gas. Given environmental concerns over increased fossil fuel development, significant opposition mobilized to “keep it [fossil fuels] in the ground” by acting to prevent not only natural gas production but also its transportation via pipelines and shipping via export terminals. Our analysis focuses on the latter component, specifically examining the long history of proposed liquefied natural gas infrastructure in two coastal communities in Oregon. Members of the public engaged in the formal siting processes and mobilized both opposition and support. We examine their use of collective action frames in both comments at public hearings and letters to the editor in local newspapers ( N = 4618) over the 16 years that these proposals were under consideration, quantifying the dynamic nature of framing using computational text analysis. We find that both groups vary their use of framing over time and by venue, reacting to exogenous events (e.g., September 11th, Fukushima) and tailor their messages to the context (e.g., an in-person hearing or a letter to the editor). Opponents concentrated on potential threats, initially emphasizing local impacts like tanker and pipeline safety but eventually focusing on climate concerns. Supporters, meanwhile, stressed the economic benefits of the projects but alternated their specific framing based on venue—focusing on employment when talking to regulatory agencies and community economic benefits in letters. While this juxtaposition of economic benefits and environmental threats was a key part of public discourse, opponents also expanded their framing to questions of local sovereignty and governance, allowing a broader coalition to develop and ultimately succeeding in defeating the proposals.

Abstract To pursue the goal of sustainable mobility, two main paths can be considered: the electrification of vehicles and the use of biofuels, replacing fossil fuels, in internal combustion engine (ICE) vehicles. This paper proposes an analysis of different possible scenarios for automobiles towards a CO2-neutral energy system, in the path of the use of biofuels and the production, distribution and use of biomethane. The study, an update of work presented previously, focuses on different scenarios that take into account numerous parameters that affect the overall efficiency of the production-and-use process. A Well-to-Wheel analysis is used to estimate the primary energy savings and reduction in greenhouse-gas emissions compared both to the use of fossil-based methane and to other fuels and automotive technologies. In particular, the study shows that the Non-Renewable Primary Energy Consumption (NRPEC) for biomethane is slightly higher (+9%) than that of biodiesel, but significantly lower than those of all the other power trains analysed: –69% compared to the battery electric vehicle (BEV) and –55% compared to bioethanol. Compared to the use of fossil natural gas, the NRPEC is reduced to just over a third (2.81). With regard to CO2 emissions, biomethane has the lowest values: –69% compared to BEV, –176% compared to bioethanol and –124% with respect to biodiesel. Compared to the use of fossil natural gas, the CO2 emissions are reduced over a third (3.55). Moreover, the paper shows that biomethane can completely cover the consumption of fossil methane for vehicles in Italy, proposing two different hypotheses: maximum production and minimum production. It is evident, therefore, that biomethane production can completely cover the consumption of fossil methane for vehicles: this means that the use of biomethane in the car can lead to a reduction in NRPEC equal to 28.9 × 106 GJ/year and a reduction of CO2 emissions equal to 1.9 × 106 t/year.

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.

Global Energy Supply

The uses of fossil fuels cause not only the resources exhaustion but also the environmental problems such as global warming. The purposes of this study are to evaluate paths to ward sustainable energy systems and roles of each renewable. In order to realize the purposes, the authors developed the global land use and energy model that figured the global energy supply systems in the future considering the cost minimization. Using the model the authors conducted a simulation in C30R scenario, which is a kind of strict CO2 emission limit scenarios and reduced CO2 emissions by 30% compared with Kyoto protocol forever scenario, and obtained the following results. In C30R scenario bio energy will supply 33% of all the primary energy consumption. How ever, wind and photo voltaic will supply 1.8% and 1.4% of all the primary energy consumption, respectively, because of the limits of power grid stability. The results imply that the strict limits of CO2 emissions are not sufficient to achieve the complete renewable energy systems. In order to use wind and photo voltaic as major energy resources we need not only to reduce the plant costs but also to develop unconventional renewable technologies. .
