An important direction in ensuring technosphere safety is the reduction of the amount of waste produced by the timber industry and emissions of harmful substances into the environment. Environmentally friendly recycling of woody biomass is expedient in terms of environmental protection and contribute to energy consumption. The purpose of this work...

This paper presents an overview of state-of-the-art in single- and multistage wood biomass gasification technologies and assesses their economic efficiency. We compare the cost of electricity generated through the use of different types of fuel (gas, diesel, coal, wood chips and wood pellets) and show that the most promising technology for processi...

A review of the methods and models used at the ESI SB RAS to assess the effectiveness of renewable energy sources (RES) was carried out. Criteria were formulated and calculation formulas were given for a preliminary assessment of the competitiveness of renewable energy sources as compared to alternative energy supply options. A mathematical model o...

In this paper, the methods of mathematical modeling are used to investigate an autonomous hybrid energy system with renewable generation.

The energy system contains photovoltaic modules, solar collectors for the solar heating system, storage batteries,...

The paper analyses current state and prospects of interstate power integration of Russia with the neighboring Eurasian countries. The integration is based on the creation and operation of interstate electric ties and joint construction of power facilities. The authors assess national programs of energy development in Russia and neighboring countrie...

One-step processes of fuel gasification were developed and widely studied during the 20th century. They remain the main ones when creating and designing modern gas-generating equipment. M any studies have shown that one-stage gasification processes have already reached the limit of improvement, beyond which a significant improvement in their perfor...
