If methanol costs are discounted altogether, the remaining production cost of bacterial protein is still 0.36 kg 1, ie more than the cost of soya protein. At these levels the particular SCP process in question is clearly not competitive. 

At present oil prices, around US 30/Bbl, the Cm values are between US 114 and 177. As oil prices tend to rise and methanol costs remain practically fixed, methanol as a fuel becomes an economically feasible alternative under Brazilian conditions and its feasibility tends to improve as oil becomes more and more expensive and difficult to obtain. 

What are the prospects for generating a substantial fraction of methanol cost-effectively from renewable or co2-free sources ... 

In the solar H2 production farm, the produced amount of the solar methanol will be reduced to 1/4, since the solar share in the solar methanol is increased from 26% (coal) to 100% (recovered COj). This will result in the increase in the solar methanol cost by 4 times, 0.6x4= 2.4 /gallon methanol (This cost dose not include the cost for CO recovery). Thus, the solar methanol produced by 100% of solar energy (solar H2) and the recovered CO2 can not be competitive to the present cost, even though it is produced by solar thermochemical process using the SCOT-solar farm. This suggests that there is an optimum where the solar methanol cost is competitive and the coal is replace by the solar Hj with a maximum solar share. 

High efficiency of direct hydrogen and methanol-based FCVs compensates for higher hydrogen and methanol costs, bringing armual fuel costs on par with ICEVs. 

The methanol-based routes are made feasible by low methanol costs. Again, the economy of scale and low gas prices are decisive factors as illustrated in Figure 1.23. Today, natural gas-based plants are running at capacities of 5000 t/d and being designed for capacities of 10000 t/d [3]. 

Assuming adipic acid costs 50.00 per pound and methanol costs 20.00 per pound, and assuming 100% yield, calculate the raw material cost of dimethyl adipate to the nearest tenth of a cent. 

Patil et al. also pointed out that using fuel cells will provide the army not only with longer operating times of equipment (which means more efficient use) but also with considerable savings on expenditures 1 gallon of methanol costing less than 0.50 is the energy equivalent of disposable (primary) batteries worth 2240. 

Based on the Pareto ranking of effects on the objective function, the key decision variables are chosen. For the DME process, the methanol cost is high, but there are assumed to be no by-product reactions. The product DME is assumed to be at its purity specification. The only methanol loss is in the waste water thus, the purity of the bottoms product of T-202 could be a decision variable. At present, approximately 0.27% of the methanol feed leaves in the waste water. Thus, the target savings attainable can be calculated as 30,300/yr.
