This chapter explores the various technological pathways and economic aspects of biogas conversion into higher-value products. It begins by emphasizing the potential of biogas as a sustainable energy source, outlining its direct applications, particularly in combined heat and power systems. The benefits of using biogas for decentralized energy generation, especially in rural areas, are highlighted, along with the challenges related to regulatory frameworks and subsidies. The chapter then delves into the techno-economic analysis of upgrading biogas to biomethane. The economic feasibility of this pathway is assessed through various case studies, revealing that profitability is often dependent on subsidy schemes like feed-in tariffs. Additionally, the chapter discusses the production of biohydrogen through biogas reforming and microbial electrolysis. While biohydrogen presents a promising avenue for clean energy, its production is currently limited by high costs and market competitiveness. Finally, the chapter examines the potential for biogas to serve as a precursor for biochemicals, such as syngas, renewable ammonia, and biomethanol. Although these products contribute to a circular economy, their economic viability remains challenged by high production costs and dependency on subsidies. Overall, this chapter underscores the critical role of policy support in advancing biogas conversion technologies and highlights the ongoing challenges in achieving economic sustainability for these renewable energy projects. © 2026 Elsevier Ltd.
