The global energy system is experiencing a transformation. An analysis of the dynamics of global energy production and consumption indicates that a paradigm shift is occurring toward more reliable and sustainable energy sources with the dominance of natural gas. Even though the reserves-to-production ratio for hydrocarbons is declining, it is natural gas that can ensure the sustainable development of the energy system to meet the growing energy needs of humankind. Natural gas can also significantly reduce the environmental burden. In the medium term, it will be the main source of energy along a gradual transition to renewable energy. Natural gas can serve as a transition fuel within a broader deployment of hybrid energy technologies. Hybridization—the generation of energy using both fossil fuels and renewable energy sources—is one of the most promising areas of energy system development, contributing to a significant reduction in greenhouse gas emissions. In our opinion, hybridization based on natural gas is a “bridge to the future” for the world energy system.

Thermal conductivity, heat capacity per unit volume and phase behavior of Shtokman gas condensate were investigated at high pressure up to 1800 MPa in the temperature interval of 245-373 K using the transient hotwire method. No crystallization was observed in the sample. The glass transition process in the Shtokman gas condensate takes place in the thermobaric interval which lies outside the range of temperatures and pressures corresponding to the production and transport of the gas condensate.

On April 17 2020 National University of Oil and Gas “Gubkin University” celebrates 90th anniversary. The article shows that all these years the University has been strictly following the principles formulated by the founder of the university, academician Ivan Gubkin. The most important of them are the following. The University is the leader of domestic higher oil and gas education, carrying out the advanced training of oil and gas engineering personnel on the basis of innovations in the content and teaching technology. The University is a polytechnic university that combines the entire technological chain of the hydrocarbon industry with its specialties and directions – from finding them to supplying to the market. The University is the driver of the scientific and technological progress of hydrocarbon energy.

This paper offers a brief look at the development of the theory and practice of tribology and tribodiagnostics in Russia. It covers the main directions in tribology, and looks at magnetofluid (ferrofluid) tribosystems, classification of triboelements, tribomonitoring systems, thin‐layer activation, renovation of tribosystems without disassembly, tribosystems with automatic wear compensation, and controlled tribochemical regimes.
