NRC says algae biodiesel isn’t sustainable at scale

In Washington, a new study from the National Research Council says large-scale algae biodiesel production—as it is now—uses unsustainable amounts of water, energy and fertilizer, including carbon dioxide, nitrate and phosphate. GHG emissions from algae biodiesel may not even be lower than petroleum-based fuels. The NRC suggests continued research into algae to find better ways of production at large-scale.
