“…A comparison of the effect of biomass material on efficiency shows that green waste is the least efficient, while the highest power plant efficiency can be obtained by using wood chips to produce syngas fuel. Ishikawa et al [52]. The dynamic characteristics of biogas power plants with combined heat and power (CHP) systems were investigated, and the possibility of using these systems as a new source to regulate the supply-demand in the electricity network was evaluated.…”

Combining heat and power (CHP) technology, which uses renewable energy sources as fuel, will be a promising solution to increase energy security. This report aims to examine CHP technologies based on renewable energy, seek to increase their efficiency and reduce the unsustainable nature of renewable resources, and then examine the existing articles from an economic and technical perspective. Heat and electricity are generated simultaneously in CHP technology; heat is the limiting factor in this issue. Therefore, it should be installed in a place requiring heat and population density because transmission losses are reduced in this case. Among renewable energy sources used as fuel for CHP power plants, biomass has the largest share, and among fossil fuels, natural gas and coal have the largest share in CHP, respectively. The United States, Russia, and China have the largest shares in renewable power plants, respectively. All the articles reviewed mention the need for heat storage for CHP power plants. If regional heating and cooling using CHP technology are used, biomass consumption can be reduced by 31.4% compared to single heating, and this amount can be used more in value-added sectors.

Preliminary preparation of waste for anaerobic digestion at thermophilic temperature conditions is the most energy-intensive stage of the process of anaerobic bioconversion of production and consumption waste organic matter, therefore, the search for ways to reduce energy consumption at this stage remains an urgent task. The article proposes a technological solution to maintain the temperature regime of the digester operation due to the utilization of existing waste low-grade energy sources using a compression heat pump. The flow diagram of the experimental biogas plant is shown and a description of its operation is given. The dependences of the absolute and specific rates of heating of the influent and cooling of the effluent on the initial temperature of the effluent are given. The principal possibility of maintaining the temperature regime in the digester is shown by using the heat recovery of the effluent using a compression heat pump.

“…The integrated energy system optimized operation could bring CO 2 emission decreasing and social welfare increasing [16] [17]. In [18], biogas plants with CHP systems are integrated to conduct long-term supplydemand adjustments. An economic dispatch model for power and heating systems are developed in [19] considered the detailed modeling of CHP units, heat boilers, electrical boilers and heat storages, with the result of reducing wind curtailment and saving energy by installing electrical boilers and heat storages.…”
