Ethanol can be produced via an intracellular photosynthetic process in cyanobacteria (blue-green algae), excreted through the cell walls, collected from closed photobioreactors as a dilute ethanol-in-water solution, and purified to fuel grade ethanol. This sequence forms the basis for a biofuel production process that is currently being examined for its(More)
The lifecycle fossil energy, greenhouse gas emissions, and water use are evaluated for a supercritical water approach to sugar production from cellulosic feedstocks. Bark and lignin are used for process heat. If grid electricity is used, the lifecycle fossil energy input is 9.0 MJ/kg of fermentable sugar. If the bark and lignin are used for combined heat(More)
