What is vital (and not vital) to advance economically-competitive biofuels production

► We are flooded by a wave of biased or even false information about biofuels. ► Most advanced biofuels cannot be economically produced compared to ethanol and H2. ► Thermodynamics determines economics. ► Cellulosic ethanol and butanol are the best short- and middle-term biofuels. ► Sugary hydrogen would be the best ultimate biofuel.
