Abstract

The paper analyzes how the geopolitical events of 2022 influenced plans for the energy transition in the EU, and how they affected the development of the renewable energy sector in Russia. In the course of the study, it was revealed that in the current conditions, the intention of the EU to carry out the energy transition has not only not weakened, but, on the contrary, has strengthened. The Russian renewable energy industry, which until 2022 developed with a significant lag compared to both developed and developing countries, after February 2022, was in limbo, because a number of Western partners left the industry or intend to leave it, and the search for Eastern partners is complicated by risks, which potential new partners may face when cooperating with Western partners, as well as by the small size of the Russian RES market, which makes potential cooperation meaningless, especially in light of the identified risks. The research methodology consists in the use of general scientific methods (analysis and synthesis, induction and deduction, etc.). The results of the study contain recommendations for Russia's energy transition policy, which could contribute to the establishment of new economic partnerships between Russia and other countries in the field of modern energy in the long term. One of the most important components of such a policy is to strengthen the nationally determined contribution to the implementation of the Paris Agreement. However, new partnerships are out of the question as long as hostilities continue.

Abstract

This paper proposes a self-filling exhaust-type natural vacuum solar distillation system for seawater desalination, which aligns with China’s “green, low-carbon, and efficient” strategy and its “carbon peak and carbon neutrality” goal. The system’s structure and working principle are described, and an experimental apparatus is built to test its water production at different temperatures. The results show that the water production and performance coefficient increase with the water temperature. At a seawater heating mass flow rate of 0.1 kg/s and a temperature of 60℃, the unit cycle water production is 13.77 kg, and the performance factor is 1.80. The paper also analyzes the economic benefits of the system, which aims to improve the desalination speed and rate of seawater, and enhance the wind power generation efficiency.
