In light of the worldwide consensus on net-zero emissions, using clean fuels to wholly or substantially replace traditional has emerged as dominant route industrial development. This paper presents a methanol-hydrogen co-combustion method for boilers, based methanol, zero-carbon fuel produced from CO₂. The technique uses boiler waste heat catalytically fracture methanol into dissociated gas (DMG), largely composed H₂ and CO. DMG is blended with original improve thermal efficiency minimize emissions. A three-dimensional geometric model was developed tiny direct-current natural (NG) research subject. combustion characteristics mixed various concentrations hydrogen were simulated finite volume approach. Blending at flow rate 10 m³/h surplus air ratio 1.2 improves NG release furnace temperature. At 5% mixing ratio, rises by up 2.2%, while average temperature reaches high 1886 K. Meanwhile, 10%, increases maximum 2.1%, 5%, 1895 Overall, greater effect increasing combustion, whereas larger potential raise

Hydrogen has emerged as a critical energy carrier for achieving global decarbonization and supporting sustainable future. This review explores key advancements in hydrogen production technologies, including electrolysis, biomass gasification, thermochemical processes, alongside innovations storage methods like metal hydrides liquid organic carriers (LOHCs). Despite its promise, challenges such high costs, scalability issues, safety concerns persist. Biomass gasification stands out dual benefits of waste management carbon neutrality yet hurdles feedstock variability efficiency need further attention. also identifies opportunities improvement, developing cost-effective catalysts hybrid systems, while emphasizing future research on improving tackling bottlenecks. By addressing these challenges, can play central role the transition to cleaner systems.

Faced with a global consensus on net-zero emissions, the use of clean fuels to entirely or substantially replace traditional has emerged as industry’s primary development direction. Alcohol–hydrogen fuels, primarily based methanol, are renewable and sustainable energy source. This research focuses sustainability presents boiler fuel blending system that uses methanol–hydrogen combinations. boiler’s waste heat catalytically decompose methanol into gas mostly consisting H2 CO, which is then co-combusted original improve thermal efficiency lower emissions. A comparative experimental study considering natural (NG) hydrogen dissociated (DMG) was carried out in small boiler. The results indicate that, controlled mixed flow 10 m3/h an excess air coefficient 1.2, 10% ratio maximizes (ηt), resulting 3.5% increase. also 1% increase NOx 25% decrease HC 5.66% improvement equivalent economics (es). Meanwhile, DMG at 15% increases ηt by 3%, reduces emissions 13.8% 20%, improves es 8.63%. DMG, partial substitute for gas, outperforms various aspects. If this technology can be successfully applied promoted, it could pave new path sector.
