I read the article, and while fascinating, it was a 2003 article based upon research conducted between 1999 and 2002.
The article addressed production of hydrogen based upon one particular form of algae used in research for many decades:
Main article: Biological hydrogen production
In 1939 the German researcher Hans Gaffron (1902-1979), who was at that time attached to the University of Chicago, discovered the hydrogen metabolism of unicellular green algae. Chlamydomonas reinhardtii and some other green algae can, under specified circumstances, stop producing oxygen and convert instead to the production of hydrogen. This reaction by hydrogenase, an enzyme only active in the absence of oxygen, is short-lived. Over the next thirty years Gaffron and his team worked out the basic mechanics of this photosynthetic hydrogen production by algae.[17]
[Preceding from another source]
While the posted paragraph which cites: "While there are some commercial reactors that grow algae under artificial light to produce food additives or supplements, these represent high-value materials so the reactor can be more expensive. For food additives, certain FDA requirements must be met, which further increases the cost of the reactor" may be valid, there are no comparables to presumed changes both in FDA requirements and changes due to research since 2002.
Moreover, I gather there are thousands of variants of algae, and we have not seen comparable research to equate various strains.
Am I missing something here?
