Question

Anyone has a chart of biofuel potential of switchgrass, miscanthus, algae, sugar cane, etc?

Answer 1

Switchgrass.

The current focus of this project is on testing a small-scale switchgrass-fired

boiler as a potential on farm heat source. Many potential applications exist on

Maryland farms for using this type of system including heating of farm buildings,

greenhouse heating, hot water heating in dairies, grain drying, and heating

of aquaculture systems. Switchgrass consistently outyielded eastern

gammagrass in a late-winter single harvest system and yields of 10 Mg/ha

appear to be readily attainable with minimal inputs after the establishment

phase. The energy content of harvested switchgrass is approximately 18MJ/

kg giving a total harvested energy content per acre equivalent to that in 530

gallons of heating oil. At current fossil fuel prices, there are not compelling

reasons for farmers to convert to switchgrass fired heating systems, especially

given the lack of readily available off-the shelf heating units. It is hoped that

this project will demonstrate the technical feasibility of biofuel-fired systems

for on farm applications. With relatively minor subsidies for water quality

benefits and reductions in net CO2 emissions these systems appear to be an

economically viable option for agriculture to address both local and global

environmental issues.

Answer 2

I strongly suspect that the process engineering and cost data are not nearly developed enough for the graphs you ask for, with the probable exception of sugar cane.
