Economic baseline assumptions
The economic evaluation will be made assuming a real interest rate of eight percent with labour wages in the range 0.5 -16 US$/hourwith a price of diesel oil of 8 -16 US$/GJ and wood fuel of 0.1 — 3.5 US$/GJ. It should be mentioned that in Sweden the labour wages are about 16 US$/h. Diesel oil is sold at about 0.3 US$/I, i. e. 8.5 US$/GJ and wood chips as a commercial fuel at 3.4 US$/GJ.
In Chapter 4, the cost of preparation of gasifier fuel is estimated to be 0.11 h + 0.04 US$/GJ, giving a cost of 0.1 -1.8 US$/GJ for the range of wages considered here. Diesel fuel in remote locations was estimated to cost 12.6 US$/GJ.
In Chapter 5, finally, the cost of coconut shell as fuel is estimated to 0.8 US$/GJ.
