Algae advantagesg g ‘Food vs. fuel’ becomes food and fuelfood and fuel

normal crops have only a 1% photosynthetic effiency, 1% photosynthetic effiency, algae at least 5% (presumably up to 14% in optimum conditions)

algae have a low land f i   ki   i ld   f footprint, making yields of biomass 15times higher than for normal cropsthan for normal crops

Challengesg Overall challenge is to develop low‐cost high‐productivity

d i       l  (    h ) production systems at scale (e.g. 1000 hectares): Open ponds account for > 90% current worldwide 

d i  b       i     i  f  bi f lproduction, but > 10 times too expensive for biofuels Photobioreactors are excellent for high‐value products, but 

    i     i  f  bi f l>> 100 times too expensive for biofuels Technical challenges are mostly upstream ‐ related to algae biology & transition from lab to outdoors

Lessons LearnedLessons Learned

Many microalgae can accumulate neutral lipidsAll  l   d  l   f bi All algae produce lots of biomass

GMO‐engineering of algae is difficult Diatoms and greens most promising No perfect strain for all climates, water types

Harvesting algal blooms from oceansg g not energetically or cost effective sea water is oligotrophic have to add nutrients like iron

low cell densities Exception coastal lagoons, possible contained environment

E.g. Commerically Spirulina from Lake Texcoco and cyanobacterialblooms in Oregon ‐ again limited
