Physiology limits commercially viable photoautotrophic production of microalgal biofuels

“

After a lot of hassle and non-scientific "referee" comments, finally we get the information out based from the work conducted under the EU-funded EnAlgae project. This technology is fated not to provide a solution to global energy needs. Photosynthesis is too inefficient, microalgae need too many nutrients, and the collective logistic demands for just to meet the quantities needed are eye-wateringly high. Genetic modification options will generate potential for planet-scale harmful algal blooms. Invest in bulk algal growth for food; do not do it for fuel.
