Abstract: The study presents the potential use of winemaking residues, specifically grape pomace, for energy purposes. The pomace was obtained from the cultivation of the Regent grape variety on three different rootstocks—125AA, 161-49, and SO 4 —as well as a control group grown on its own roots. The research included determining the calorific value and combustion heat, conducting a technical and elemental analysis of the potential biofuel, as well as estimating emission indicators (CO, CO 2 , NO x , SO 2 , and particulate matter) and the theoretical volume of flue gases based on stoichiometric equations. The study revealed significant differences among the combustion heat, tested properties and calorific value, ash content, and the total volume of flue gases. The highest calorific value (17.7 MJ kg −1 ) and combustion heat (18.9 MJ kg −1 ) were obtained for pomace from the SO 4 SO 4 rootstock, while the lowest values were observed in the control group (17.0 MJ·kg −1 and 15.8 MJ·kg −1 , respectively). The highest ash content was also recorded for the SO 4 rootstock (9.2%), with the lowest in the control group (6.7%). The control group exhibited the lowest CO 2 emissions at 1390.50 kg·Mg −1 , while the highest emissions were found in the pomace from the SO 4 rootstock (1478.8 kg·Mg −1 ). Regarding the total flue gas volume, the highest volume was estimated for the pomace from the 125AA rootstock (7.8 m 3 ·kg −1 ) and the lowest for the control group (7.3 m 3 ·kg −1 ). The research demonstrated that grape pomace possesses favorable energy properties and could serve as a potential biofuel, contributing to the fuel and energy balance of agricultural production enterprises. The analyzed biomass exhibits properties similar to agrobiomass.
