The growing global emphasis on climate change mitigation has intensified efforts to transition from carbon-intensive energy sources to sustainable, low-carbon alternatives. In this context, district heating facilities, particularly in regions like Russia, represent a key opportunity for reducing greenhouse gas emissions through innovative energy solutions. The paper reports on the results of studies exploring various avenues for a transition to a carbon-neutral economy, particularly in the Russian Federation. The research aims to develop a hydro-steam turbine installation for geothermal power plants and heating boilers to substantiate and create new energy production infrastructure. For this purpose, the authors identify the volume of the market for hydro-steam turbines for boiler houses required to predict the reduction of CO2 emissions as a result of the application of the installations in Russia. Proceeding from the performed calculations, the paper offers an estimate of the decrease in CO2 emissions due to the implementation of this innovation in Russia. The use of hydro-steam turbine installations in cogeneration schemes at heating plants will increase the reliability of power supply to district heating sources and reduce specific fuel consumption in the production of electricity. The total theoretical potential of greenhouse gas emission reduction due to the implementation of hydro-steam turbines in Russian boiler houses exceeds 500,000 tons CO2 annually.
