Abstract (AB)Since 1999, Mauritius has embarked on a strategy to install bagasse cum coal cogeneration plants using high-pressure boilers and the conventional steam cycle. Electricity production had reached 200 kWh/t cane but, after satisfying its own heat and power use, the net exportable energy is 130 kWh/t cane. It is expected that electricity produced from bagasse will attain 700 GWh in 2012 from 5.5 million tonnes cane. Since massive investment has already been made, it is unlikely that, in the short-term, surplus energy for export would be produced, using a different co-generation set-up than the conventional steam cycle. The aim of our study is to ascertain whether increasing the amount of exportable electricity, gas or liquid fuel from bagasse would be possible without affecting the set-up of existing co-generation plants. The study reviews and evaluates the surplus exportable energy potential, based on current research in Mauritius and from international literature, on concepts, not yet adopted or widespread in the cane sugar industry. Higher fibre or high quality cane, trash recovery, bagasse drying, condensing boiler, bagasse gasification gas turbine technologies, liquid fuel from bagasse, hydrogen from bagasse for fuel cells and cellulosic ethanol are among them
