A published report in Environmental Science and Technology claimed that "conventional crops have lower environmental impacts than algae in energy use, greenhouse gas emissions and water." The Algal Biomass Organization (ABO), the trade association for the algae industry, today challenged the conclusions of the published report.

The report was based upon obsolete data and grossly outdated business models and overlooked tremendous improvements in technology and processes across the production cycle.

Few of the many concerns of ABO about the report are:

Assumptions about algae growth systems

Assumptions about co-location

Assumptions about water use

Assumptions about energy use

Assumptions about purchase of CO2 and fertilizer

Algal Biomass Organization firmly believes life cycle assessments are critical to the development of the industry. Its membership supports the development of robust LCAs, but believes that the process should include input from a multitude of stakeholders, including algae technology companies, NGO’s and other scientists.

This is going to be a hot debate.
I wish I could the report.

Because the authors admittedly did not consider the full algae fuel cycle, which allows energy reuse through biodigester biogas combustion coupled with the carbon recycling from all of the aspects of biodigestion, the report errantly gives a higher emissions burden.
