THE STATUS OF ALGAL BIOFUEL DEVELOPMENT

The report finds that current algal biofuel technologies are not yet economically or environmentally superior to fossil fuels, citing low energy return on investment (EROI) and high greenhouse gas emissions. While theoretical yields are high, large-scale commercialization is estimated to be years or decades away. The document argues that viability depends on integrating production with wastewater treatment, industrial flue gas for CO2, and the development of marine algae strains via molecular engineering to reduce freshwater and land demands.

• Current algal biofuel production is not an improvement over conventional fossil-based transportation fuels in terms of economics or climate change mitigation.
• The energy return on investment (EROI) for algal biofuels is currently too low to be sustainable, estimated at 5 to 10 times less than that of gasoline.
• Lifecycle analyses of greenhouse gas emissions for algal biofuels vary widely; some studies show emissions significantly higher than those of other biofuels like corn, soybeans, and camelina.
• Large-scale commercialization is not imminent, with some estimates suggesting it is several years or even decades away, and may require 5 to 15 years of consistent operation once suitable strains are identified.
• Integrating algal production with wastewater treatment (WWT) can improve EROI to 1.44 and reduce costs by avoiding nitrogen removal expenses, potentially saving nearly $50,000 per hectare per year.
• Marine algae offer a more sustainable alternative to freshwater algae by eliminating the need for freshwater and reducing land use and fertilizer requirements.
• The use of genetically modified (GM) algae presents ecological risks, including the potential for horizontal gene transfer to wild species and the infiltration of toxins into drinking water supplies.
• Theoretical maximum yields for algal biofuels are significantly higher than current oil palm production, ranging from 47,000 to 308,000 liters per hectare per year compared to 5,950 liters for oil palm.
