Biomass has recently gained recognition as a promising renewable energy resource with the potential to meet the growing global demand for continuous, clean power generation. Among thermochemical conversion technologies, gasification is considered one of the most viable approaches, offering cold gas efficiencies typically between 65% and 80%, depending on the feedstock and reactor design. Nevertheless, integrating producer gas into residential or commercial energy systems remains difficult due to technological and operational challenges. Critical issues include biomass supply chain management, pre-treatment and drying to achieve moisture content ideally below 15%, and effective gas cleaning and conditioning. Tar formation represents one of the most significant barriers, with levels commonly ranging from 2 to 10 g/Nm & sup3;, while for engine-grade applications, concentrations must be reduced to below 100 mg/Nm & sup3;. Similarly, particulates need to be controlled to <50 mg/Nm & sup3;, and alkali metals must be removed to prevent fouling and corrosion. Despite the development of various gasifier configurations, such as downdraft, fluidized bed, and plasma-assisted systems, an efficient and scalable design that achieves cold-gas efficiencies above 80% while maintaining tar concentrations below 0.1 g/Nm & sup3; remains lacking. Recent research emphasizes that next-generation gasification systems integrated with advanced gas conditioning techniques-such as catalytic tar cracking, plasma reforming, and hot-gas separation-offer a pathway to overcome these obstacles. Such advancements would enable the production of high-quality syngas suitable not only for thermal power and combined heat and power (CHP) generation but also for hydrogen production.
