The energy of the future. A look at decades ahead
The level of technological development of civilization is determined by the scale of energy development. Sergey Alekseenko, the 2018 Global Energy Prize laureate , head of the Laboratory of Heat and Mass Transfer Problems, Institute of Thermophysics SB RAS, will talk about energy development trends in the coming decades, taking into account environmental restrictions, at his lecture, which will be held on October 29 as a part of the Energy of Knowledge Program of the Global Energy Association at the Summit ‘Big Challenges for Society, State and Science’ organized by the Scientific and Technological University ‘Sirius’ (Sochi).
According to Sergey Alekseenko, the directions of development of the energy industry should be reviewed from different time perspectives. In the coming years and decades, the development of environmentally friendly and efficient technologies for the processing of fossil fuels (oil, coal, gas), on the basis of combined-cycle plants and methods for the deep processing of coal, will be the most relevant. Despite warnings of impending exhaustion of fossil fuels (40-60 years for oil and gas, 200-400 years for coal), there is no doubt that for resource-rich states it will remain a priority among other energy carriers in the coming decades.
In the far future, more active development of renewable energy sources and implementing of effective methods for converting and storing energy, including fuel cells, will begin. These processes have already been launched, but a radical change in the structure of global energy sector because of the displacement of coal and its replacement with carbon-free sources will happen much later. According to the expert, carbon-free sources will begin to dominate around year 2050.
Among the most promising types of renewable energy, the scientist distinguishes solar energy and geothermal energy with a gradual transition to the use of deep heat. Petrothermal energy does not need energy storage, in contrast to renewable energy sources, such as the sun and wind, which gives it additional advantages.
Sergey Alekseenko, Head of the Laboratory of Heat and Mass Transfer Problems, Institute of Thermophysics SB RAS has become the Global Energy Prize laureate for the preparation of thermophysical foundations for the creation of modern energy and energy-saving technologies that allow to design environmentally friendly thermal power plants.
