俄罗斯与欧盟之间的天然气博弈集中在交易机制、输气管道和企业运营管理三个领域,双方在上述领域的分歧经常酿成争端,引发危机。2022年俄乌冲突的爆发进一步加剧了欧盟天然气危机,俄欧在天然气领域中的相互依赖关系也发生了一定程度的变... 俄罗斯与欧盟之间的天然气博弈集中在交易机制、输气管道和企业运营管理三个领域,双方在上述领域的分歧经常酿成争端,引发危机。2022年俄乌冲突的爆发进一步加剧了欧盟天然气危机,俄欧在天然气领域中的相互依赖关系也发生了一定程度的变化,俄罗斯占据上风的局面有所改变,其优势地位有所下降。短期来看,俄欧在天然气领域相互依赖的敏感性和脆弱性程度依旧较高,中断天然气贸易的冲击过大以及双方政策工具箱中缺乏短期可行的低成本替代措施,使得双方暂时不会完全中断贸易关系。长期来看,随着“脱钩”政策逐步落实,双方之间的相互依赖程度将不断下降。但是危机和战争都不能从根本上改变俄欧天然气合作的互利性,只是由于双方对能源安全的内涵有不同的理解,且美国不断干扰双方之间的天然气合作,俄欧在天然气领域将更多呈现出竞争性和不确定性。 展开更多

In efforts to overcome an foreseeable energy crisis predicated on limited oil and gas supplies, reserves; economic variations facing the world, and of course the environmental side effects of fossil fuels, an urgent need for energy sources that provide sustainable, safe and economic supplies for the world is imperative. The current fossil fuel energy system must be improved to ensure a better and cleaner transportation future for the world. Despite the fact that the marine transportation sector consumes only 5% of global petroleum production; it is responsible for 15% of the world NOx and SOx emissions. These figures must be the engine that powers the scientific research worldwide to develop new solutions for a very old energy problem. In this paper, the most effective types of marine power plants were discussed. The history of the development of each type was presented first and the technical aspects were discussed second. Also, the fuel ceils as a new type of power plants used in marine sector were briefed to give a complete overview of the past, present and future of the marine power plants development. Based on the increased worldwide concerns regarding harmful emissions, many researchers have introduced solutions to this problem, including the adoption of new cleaner fuels. This paper was guided using the same trend and by implementing the hydrogen as fuel for marine internal combustion engine, gas turbines, and fuel cells. 展开更多
