Bioenergy Course

Lesson 1 • Sustainability Principles in Bioenergy

Introduces land use, water, biodiversity, and carbon balance considerations. Establishes the sustainability lens applied throughout the course.

Lesson 2 • Biomass Feedstock Categories

Surveys agricultural residues, energy crops, forestry waste, and organic municipal waste as feedstocks. Connects feedstock diversity to conversion pathway selection.

Lesson 3 • Primary Bioenergy Conversion Pathways

Introduces thermochemical, biochemical, and physicochemical conversion routes at a conceptual level. Provides the framework used throughout all subsequent chapters.

Lesson 4 • What Is Bioenergy

Defines bioenergy, its biological origins, and distinction from fossil fuels. Anchors the chapter by framing bioenergy within renewable energy categories.

Lesson 1 • Feedstock Collection and Preprocessing

Examines harvesting, size reduction, drying, and densification operations. Preprocessing quality directly affects conversion efficiency and cost.

Lesson 2 • Biomass Resource Mapping

Teaches geographic information tools and statistical methods for quantifying regional biomass availability. Outputs feed directly into supply chain design.

Lesson 3 • Feedstock Characterisation Methods

Covers proximate and ultimate analysis, moisture content, and energy density measurement. These metrics directly determine conversion technology suitability.

Lesson 4 • Supply Chain Risk and Seasonality

Analyses seasonal availability fluctuations, supplier diversification, and contingency planning. Robust supply chains are essential for continuous plant operation.

Lesson 1 • Emissions Control in Thermochemical Plants

Addresses particulate matter, NOx, SOx, and CO emissions and abatement technologies. Regulatory compliance and community acceptance depend on effective emissions management.

Lesson 2 • Heat and Power Generation from Biomass

Covers steam Rankine cycles, organic Rankine cycles, and combined heat and power configurations. Thermal efficiency optimisation is central to project economics.

Lesson 3 • Gasification Technology and Design

Explains updraft, downdraft, and fluidised bed gasifier configurations and syngas composition. Syngas quality determines downstream power or fuel synthesis options.

Lesson 4 • Biomass Combustion Principles

Covers stoichiometry, flame temperature, and excess air requirements for biomass combustion. Combustion is the most widely deployed thermochemical pathway globally.

Lesson 1 • Lignocellulosic Ethanol Production

Details pretreatment, enzymatic hydrolysis, fermentation, and distillation steps for cellulosic ethanol. This pathway unlocks non-food biomass for liquid fuel production.

Lesson 2 • Anaerobic Digestion Fundamentals

Explains hydrolysis, acidogenesis, acetogenesis, and methanogenesis stages and microbial communities. Biogas yield and quality depend on mastering these four sequential stages.

Lesson 3 • Fermentation-Based Biofuel Pathways

Covers starch and sugar fermentation to ethanol and emerging pathways to butanol and other alcohols. Feedstock choice and organism selection drive yield and cost outcomes.

Lesson 4 • Anaerobic Digester Design and Operation

Covers continuous stirred tank, plug flow, and high-rate digester configurations and operational parameters. Proper design ensures stable performance across varying feedstock inputs.

Lesson 1 • Biofuel Blending and Infrastructure

Addresses blend ratios, compatibility with engines and pipelines, and distribution logistics for biofuels. Infrastructure readiness is a key determinant of biofuel market penetration.

Lesson 2 • Sustainable Aviation Fuel Pathways

Surveys HEFA, alcohol-to-jet, Fischer-Tropsch, and power-to-liquid routes for biojet fuel production. Aviation decarbonisation creates strong demand for certified sustainable aviation fuel.

Lesson 3 • Hydrotreated Vegetable Oil and Renewable Diesel

Explains hydroprocessing of lipids to produce drop-in renewable diesel and its advantages over FAME biodiesel. Renewable diesel is compatible with existing fuel infrastructure.

Lesson 4 • Biodiesel Production via Transesterification

Covers feedstock oils, catalyst selection, reaction conditions, and glycerol co-product management. Biodiesel is the most commercially mature liquid biofuel globally.

Lesson 1 • Greenhouse Gas Accounting for Bioenergy

Covers biogenic CO2 treatment, land use change emissions, and global warming potential calculation. Accurate GHG accounting is required for regulatory compliance and carbon markets.

Lesson 2 • Life Cycle Assessment Methodology

Explains goal and scope definition, functional unit selection, system boundary setting, and ISO-aligned LCA phases. Methodological rigour determines the credibility of LCA results.

Lesson 3 • Carbon Intensity Calculation and Benchmarking

Applies pathway-specific carbon intensity calculations and compares results against fossil fuel benchmarks. Carbon intensity scores determine eligibility for low-carbon fuel incentives.

Lesson 4 • Inventory Data Collection and Databases

Teaches primary data collection, ecoinvent and other background databases, and data quality assessment. Inventory quality is the single largest source of LCA uncertainty.

Lesson 1 • Permitting and Regulatory Compliance

Surveys environmental impact assessment, air and water discharge permits, and feedstock certification requirements. Regulatory timelines significantly affect project schedules and costs.

Lesson 2 • Techno-Economic Analysis Framework

Introduces capital cost estimation, operating cost breakdown, and levelised cost of energy calculation. Techno-economic analysis is the primary tool for comparing bioenergy options.

Lesson 3 • Revenue Streams and Market Structures

Examines electricity sales, heat offtake, biofuel sales, carbon credits, and digestate markets. Stacking multiple revenue streams improves project bankability.

Lesson 4 • Risk Assessment and Mitigation Strategies

Identifies feedstock, technology, market, and regulatory risks and maps mitigation measures. Systematic risk management protects project returns and lender confidence.

Lesson 1 • Strategic Roadmapping for Bioenergy Deployment

Teaches technology readiness assessment, stakeholder alignment, and phased deployment planning for national or corporate bioenergy strategies. Roadmaps translate vision into actionable investment plans.

Lesson 2 • Bioenergy with Carbon Capture and Storage

Examines BECCS system design, CO2 capture technologies, transport, and geological storage for negative emissions. BECCS is a critical tool in deep decarbonisation scenarios.

Lesson 3 • Biorefinery Concept and Design

Applies cascading biomass use principles to maximise energy, chemical, and material outputs from a single feedstock. Biorefinery integration improves economics and reduces waste.

Lesson 4 • Sector Coupling and Energy System Integration

Explores bioenergy's role in power-to-X, district heating, and industrial decarbonisation within integrated energy systems. Sector coupling maximises bioenergy's system-level value.
