New research using real-world data casts doubt on the energy efficiency of diesel alternatives that come from phytoplankton.
New research using real-world data casts doubt on the energy efficiency of diesel alternatives that come from phytoplankton.
Biofuels made from algae have had their time in the sun, with years of highly publicized investments from fossil fuel companies, such as Exxon and Chevron, and studies showing potential for the energy source to replace fossil fuels. New research suggests, however, that biodiesel derived from microalgae may actually emit more carbon during production and use than petroleum-based diesel.
The biofuel’s poor performance is due to its manufacturing process, which requires more energy than the final product can produce.
