What This Means for Your Design

You can make hydrogen fuel from leftover stuff from making ethanol (like from sugar cane). It's cleaner than using fossil fuels and can be done at a certain cost, but you need to process a lot of the leftover stuff to make it work well.

How to use in your project

  • 1.Use the LCOH figure to benchmark the economic viability of your proposed sustainable energy solution.
  • 2.Cite the carbon footprint data to support environmental claims for your design.
