What’s So Advanced about Advanced Biofuels?  Presentations for Public Use

This most recent presentation was prepared for a National Energy Education Development (NEED) Project at the US Department of Energy.  It includes a “Biofuels 101” section, materials for group discussions of sustainability issues and slides about 2018 US tax policy questions.

View Presentation or open with Google Slides


Initially prepared for a middle school class, this presentation grew, was revised for the 2012 Dupont Summit, and is appropriate for any individual or group beginning to think about advanced biofuels.

The presentation answers the questions: What Are Advanced Biofuels? Why Are They Important?  What Are They Used For?  How Are They Made?  Can We Buy Them NOW?

It also includes a class/group activity to develop a deeper understanding of the concept of sustainability from economic, environmental and social perspectives.  After the exercise and a review of some elements pertinent to each of those legs of the sustainability analysis stool, the presentation goes into deeper discussions of the make-up of plant cells, explanations of cellulose, hemicellulose and lignin.  We hope in future presentations or additions to this presentation to delve into the properties and construction of algae and cyanobacteria, as well.

The presentation wraps up with a list of jobs related to an advanced biofuels industry.

This version of the presentation is prepared to illustrate and explain the philosophy of these introductory presentations at the National Energy Education Summit — June 7, 2016 — Washington, DC

The notes pages include useful links that provide background information for presenters, students and audiences of all kinds.

Advanced Biofuels USA Presentation for National Energy Education Conference 2016



The following presentation was prepared to give students an introduction to advanced biofuels, and to teach about researching online using the Advanced Biofuels USA website as a library resource that links to articles in publications around the world.

Students discuss the role of judgment and discernment when doing online research.  They discuss how to look for bias that might be reflected in what they read online.

These PowerPoint presentations can also serve as a primers for use by teachers, students, campus groups, civic or church organizations.  They describe, step by step,

  • what advanced biofuels are,
  • why they are important,
  • what key laws and regulations have been passed and implemented to encourage and promote the development of advanced biofuels,
  • summaries of processes used to convert biomass to advanced biofuels, and
  • the challenges and issues that must be overcome and resolved if this world can have successful, useful advanced biofuels production.

They also include some pages of

  • questions and thoughts;
  • class or student projects; and
  • advanced research suggestions.

A companion publication (teacher’s edition, if you will) that provides depth and background for this presentation is presented in Biofuels Basics, also part of this Biofuels Basics section of this web site.

For those interested in using this presentation for potential investors, or for those thinking of participating in any level of the value chain involved in biofuels and advanced biofuels, the materials in the About Advanced Biofuels for Growers and Investors may prove useful.

Advanced Biofuels:  Meeting Challenges in Fuel Supplies and Energy Efficiency

Advanced Biofuels: Meeting Challenges in Fuel Supplies and Energy Efficiency This presentation was prepared for career tech/automotive classes.  It begins with a summary of challenges to getting advanced ethanols and drop-in biomass-based fuels into production and to the marketplace.  The second part discusses the types of motors being designed and used that optimize the characteristics of ethanol in order to achieve the similar optimized mileage, regardless of ethanol/gasoline blends used.  Companion pieces for teachers or discussion leaders are the Biofuels Basics page referenced above and a paper, New Engine Technologies Could Produce Similar Mileage for All Ethanol Fuel Mixtures, (updated in August 2012) by Robert E. Kozak.

Cellulosomes by Drew Sowersby:  The enzymes responsible for degrading cellulosic material into useful sugars form an interesting supercomplex called a cellulosome. This complex is tethered to the membrane of the Clostridium bacteria.  I have attached a presentation I made concerning these protein monstrosities.   Slide 9 shows multiple cellulosomes coming together to form a true miracle in the evolution of life.
