This study demonstrates the potential of waste heat recovery using transcritical-subcritical parallel ORC with various working fluids. The research evaluates cycle's performance thermodynamic and thermo-economic models consideration five different Among these fluids, R123 is found to achieve highest exergy efficiency when used as fluid in proposed system. To assess economic performance, concept specific investment cost (SIC) employed, which quantifies ratio total net output power. results indicate that offers best for system, resulting lowest SIC, amounting 3107 $/kW. On other hand, R600a produces value same operating conditions, 3688 findings highlight favorable its advantage terms SIC. Conversely, presents under similar conditions. Finally, genetic algorithm (GA) employed perform a multi-objective optimization reveal bi-objective framework, reaches peak at 47.62%, aligning SIC 2643

The optimal utilization of biomass relies heavily on the specific material and individual needs. Cereal by-products can potentially be employed in thermochemical processes such as pyrolysis gasification. To compare sources, ultimate analysis, biochar potential, proximate thermal gravimetric price per megajoule generated heat, surface texture, availability are used. A global survey wastes opportunities for heat generation is presented current article. Here, nine different cereal-based agricultural waste products (barley, wheat, millet, oats, rice, rye straw, sorghum straw/stalk, maize cob) studied. compared based calorific value, water content, volatile matter, ash content chemical composition, bulk density, charring properties, availability, transportation. According to estimate, 156 million metric tonnes year, or 6% India's total emissions, could eliminated by rice husk alone. Wheat straws, other hand, cut emissions 2%. Additionally, processing these feedstocks might result production 40 GW electrical energy, which would increase installed capacity national electric grid 9%.

Integrating renewable energy sources into systems is crucial for sustainability and reducing CO2 emissions. The sorption-enhanced gasification process, when combined with renewables, offers a path toward sustainable systems. In this study, novel integration of solar-based process biomass proposed, aiming electricity hydrogen generation. entire system's performance has been investigated from the perspectives energy, exergy, economics, emergy analysis. Furthermore, response surface methodology employed to optimize overall system in terms exergy efficiencies levelized cost energy. study's results reveal that integrated shows its optimum operational condition at steam-to-biomass ratio 0.53 capture efficiency 65 %. determined be 67.2 % net electrical power generation 5.251 MW. whole 71.89 Optimization report 7.87 $/MWh. From analysis perspective, indicate introduced system, renewability index 0.22, low dependency on non-renewable inputs. With 1.95, qualifies as moderately sustainable, demonstrating superior compared conventional co-generation
