Seeing a Future Beyond the Hype for Algae Bioenergy
'Algae' is often referred to as a 'Next Big Thing' category technology by cleantech investors and bio-industrialists. But I've found that most people have no real understanding of what algae 'is' or 'isn't' as a new energy solution.
I've posted six videos that should give that quick overview. Some videos contain statements that I find to be short-sighted or overly focused on near-term challenges. But overall, they describe the potential of algae bioenergy solutions in a very accessible way. Enjoy!
Why algae?
[Editor's note: Great video lecture via Twitter AlgaMan, Thanks!!!]
- Algae are 'original oil producers' on Earth (Video #1) - petroleum is the result of ancient sea-living microbes that arranged carbon and hydrogen into complex chains that we blow up for energy.
- Algae grow quickly using carbon dioxide (via gas, or biomass waste), light and water as their fuel source. (Video #3) Their byproduct? High energy content hydro-carbon chains.
- Algae produce tremendous yields (Est 10,000-30,000 gallons/acre/year), compared to plant based biofuels (Corn at 20/year; Palm at 800) (Video #4)
Video #1 - MIT's Algae biophotoreactor
Scientific America produced show with Alan Alda. The program was focused on hydrogen (e.g. electricity) with a special segment on algae-to-hydrogen production.
Video #2 - Solayzme
