Lux Research has put together a group of cutting-edge emerging technology companies to watch in 2013, mostly energy tech.

1). Beta Renewables : A $350 million joint venture between Gruppo Mossi & Ghisolfi and TPG, Italian company Beta Renewables is scaling up a commercial cellulosic ethanol factory, which it began operating in the fourth quarter of 2012 in Italy. The plant is supposed to eventually make 20 million gallons of cellulosic ethanol per year, starting from an initial volume of 40,000 tons. Beta Renewables uses enzymes to break down non-food biomass and then uses a fermentation process to turn it into biofuels.
