ES97B - Bioenergy and Biotechnology

(15 Credits)

Aims: To impart a deep understanding of the principles of modern bioenergy and biotechnologies, including biofuels from a variety of sources, biomass chemistry and treatment, conversion of biomass and ethical and practical considerations. Students will gain a through understanding of the potential for sustainable biotechnologies for power production as well as the fundamental principles underlying biomass formation/production and energy conversion.

Learning Outcomes: Upon completion, students will be able to:

Demonstrate an advanced understanding of biomass chemistry and a detailed knowledge of different types of biomass for modern biotechnology applications. Critically evaluate the suitability and feasibility of biofuels for a given application.

Understand the physical treatment and handling of biomass using advanced modern methods. Understand complex thermal biomass conversion processes, including gasification, combustion, pyrolysis and liquefaction.

Perform detailed analyses of the complex underlying principles of biochemical biomass conversion, including biogas and biofuel production from various sources. Perform economic analyses and critically assess the impact on the environment of biomass production and use.

Demonstrate a deep understanding of the modern biorefinery concept, including process such as hydrolysis of biomass, biobased fuel additives, lignin conversion and levulinic acid and furfural conversion.

Understand logistical and ethical considerations in the context of the environment and be able to critically assess the feasibility of biorefineries based on logistical and
environmental constraints.
