The energy sector in Poland is currently calling for dynamic redevelopment and cleaner energy. This country is world famous for its high level of coal production, from which it does not want to retreat in the next two decades. For this reason, it is safer to gradually reduce the use of coal while increasing the consumption of gas and simultaneously developing green energy. However, the Polish gas sector is still dependent on Russian gas supplied through the Yamal gas pipeline. Taking into consideration Polish geopolitics, this state of affairs poses a huge challenge and a threat to Poland’s energy security. That is why the concept of the North-South Gas Corridor was introduced. It is intended to be a network of gas pipelines that connect the countries of Central and South Europe to two gas terminals (in Poland and Croatia), which will supply gas from a chosen source. This article presents the current condition of the gas sector in Poland. It focuses on the North-South Gas Corridor project and its impact on the energy security of Poland. An analysis of documents and field research shows that the North-South Gas Corridor provides Poland with an opportunity to diversify the sources and directions of gas supply over the next few years.

The power system interconnection between Northeast Asian countries has been discussed since 2000 but has not been realized to date due to various obstacles. This paper specifies the expected future energy policy, long-term energy supply plan, and necessity of power interconnection from the Korean viewpoint, including the climate change agreement. There are very many interconnection scenarios presented by various institutes in NEA countries now. These studies contain the overall preliminary feasibility results but do not consider the environmental effects, energy security, and market reforms. Do these existing studies show how we could interconnect specific countries? This paper discusses the trading potentials for green energy utilization between countries and some obstacles to be removed to promote the energy interconnection projects from technical, economic, marketable, and energy security standpoints. Especially, energy security in terms of politics, as well as vulnerability characteristics of renewable energy, could cause the interconnected system blackouts. These could be a serious obstacle to realization and continuous stable operation of these interconnection projects. Finally, this paper will specify the future directions and possible scenarios for power system interconnection by integrating these issues comprehensively from Korea's perspective.

Considering the quest to meet both sustainable development and energy security goals, we explore the ramifications of explosive growth in the global demand for lithium to meet the needs for batteries in plug-in electric vehicles and grid-scale energy storage. We find that heavy dependence on lithium will create energy security risks because China has a dominant position in the lithium supply chain and both Europe and North America seek to curtail reliance on China throughout their supply chains. We also find that efforts to expand lithium mining have been much less successful in Chile, the United States, and Europe than in Australia. Local communities resist licensing of new lithium mines due to a variety of environmental, social, and economic concerns. There are alternative technologies that may make lithium mining more sustainable such as direct lithium extraction, but the timing of commercialization of this process is uncertain. Progress is also being made in battery recycling and in alternative battery designs that do not use lithium. Such advances are unlikely to attenuate the global rate of growth in lithium demand prior to 2030. We conclude that tradeoffs between sustainability and energy security are real, especially in the next decade.

Abstract Energy security and environmental measurements are incomplete without renewable energy therefore there is a dire need to explore new energy sources. Therefore, the aim of this study is to measure the wind power potential to generate the renewable hydrogen including its production and supply cost. We used first order eneginnering model and net present value to measure the levelized cost of wind generated renewable hydrogen by using the data source of Pakistan metorological department and State bank of Paksitan. Results shows that the use of surplus wind and renewable hydoregn energy for green economic production is suggested as an innovative project option for large-scale hydrogen use. The key annual running expenses for hydrogen are electricity and storage cost, which have a major impact on the costs of renwable hydrogen. Also, the results indicates that project has the potential to cut CO2 pollution by 139 million metric tons and raise revenue for wind power plants by 2998.52 million dollars. The renewable electrolyzer plants avoided CO2 at a rate of 24.9–36.9 $/ton under baseload service, relative to 44.3 $/ton for the benchmark. However, in the more practical mid-load situation, these plants have a significant benefit. Further, the wind generated renewable hydrogen deliver a 6–11% larger than annual rate of return than the standard CO2 catch plant due to their capacity to remain running and supply hydrogen to the consumer through periods of plentiful wind and heat. Also, the measured levelized output cost of hydrogen (LCOH) was 6.22$/kgH2 and for the PEC system, it was 8.43 $/kgH2. Finally, its mutually agreed consensus of the environmental scientist that integration of renewable energy is the way forward to increase energy security and environmental performance by ensuring uninterrupted clean and green energy. Further, this application has the potential to address Pakistan’s urgent issues of large-scale surplus wind and solar-generated energy, as well as rising enegry demand.

Gas Supply

Recently there has been an ongoing discussion about energy security. This has been caused by tensions affecting international relations, and the emergence of new geopolitical threats. As one of the main sources of primary energy, natural gas is an obvious subject of interest in this discussion. In Europe, the natural gas market is rapidly evolving, which has resulted in a lack of clarity regarding who is responsible for the security of the gas supply. It is not clear now how to measure the security of the gas supply in economic estimates and by whom that security should be financed. In this paper, the authors present an approach which can be used for valuation of energy security concerning the security of natural gas storage using stochastic modelling based on the mathematical model of the “Newsvendor problem”. The valuation is made from the point of view of countries and considers their individual attitudes to the risk of disruption of deliveries, which is a novel approach to the problem. The authors believe that the current level of storage capacities, as compared to the demand for natural gas, can show the attitude of each country to the risk and potential cost of stockout. In line with this belief, the target value in the model is not the optimal level of inventory, but the cost of stockout. The results show significant variations in the assessment of the risk. The future of natural gas as an important fuel and source of primary energy in Europe is not clear and unfavorable changes have been sped up by the COVID-19 pandemic. Gas (energy) companies in Europe are turning to decarbonization and green energy, and the pandemic has accelerated these changes. European energy companies used to see the use of natural gas as a transition fuel and a key component of their long-term decarbonization strategies, but now they are switching to multi-energy models through massive investments in renewables and hydrogen. Experts expect that gas will remain an important part of Europe’s energy supply, but it may be gradually replaced by hydrogen and renewables.

Pakistan is heavily dependent on imported fuel for power generation. Depending on imported fuel has not only increased GHG emissions, but it has also put a burden on the national exchequer and raised apprehensions on energy security. This paper thus investigates the consequences of oil-based power generation on the economy, environment, and energy security of Pakistan. SWOT-Delphi approach has been adopted. The study discovered that the use of imported oil for power generation is detrimental to the economy, environment, and energy security of Pakistan. It further suggests that Pakistan should immediately abandon oil-based power generation and explore green energy alternatives for its sustainable economic growth. This study uses a hybrid model that combines strength, weakness, opportunity, and threat (SWOT) analysis with the Delphi method.
