Biomass conversion strategies are the processes that convert biomass into energy. These technologies are classified as thermochemical, physicochemical, and biochemical conversion processes. Among them, thermochemical conversion involves using heat and chemical reactions to convert biomass into energy-rich products. Bonds between neighboring carbon, hydrogen, and oxygen molecules are broken down in thermochemical conversion processes to liberate the stored chemical energy (from photosynthesis). This chapter provides a brief overview of thermochemical processes and conversion technologies, focusing on combustion, pyrolysis, liquefaction, and gasification. Furthermore, considering the potential applications, several types of biomasses, such as metal-based catalysts built of inexpensive and abundant components, are being targeted for economically viable hydrogen production through pyrolysis, gasification, and steam reforming with and/or without chemical-looping technologies. Biofuels derived from forestry, agriculture, and energy crop systems are also briefly reviewed as potentially viable resources to combat climate change and reduce greenhouse gas emissions.
