If the economics of natural gas change, a flex fuel vehicle could still run on methanol made from coal, biomass and possibly recycled carbon dioxide, if that technology proves economical.
LS9 now needs to prove that its technology is economical and can produce fuels on a large scale, says Jim McMillan, principal biochemical engineer in the National Renewable Energy Laboratory's Bioenergy Center, based in Golden, CO. "I don't doubt that [making hydrocarbon fuel from microbes] can be done; the question is how quickly and at what cost," he says.
Volumetric fracturing is a primary stimulation technology for economical and effective exploitation of tight oil reservoirs.
As each oilseed comprises of different architecture, the process needs to look for suitability of technology in economical and technical ways.
The steeply rising oil prices of the 1970s and '80s revived interest in coal liquefaction and stimulated a search for other technologies for economical conversion of coal to liquid products, especially in the U.S. and other oil-dependent countries possessing extensive coal reserves.
In the drive for modernization, evolving technologies and economical and social structures alter existing systems and make many sectors and groups in the ecosystems more vulnerable to significant variations in climate and sea level Ericksen et al. (1993).
These developed technologies yield economical ways to genotype one million SNPs across the entire genome in large-population studies.
By using the multi-criteria decision making technique of Analytic Network Process (ANP), a multi-criteria evaluations of six different energy plants were performed with respect to the major criteria such as technology and sustainability, economical suitability, life quality and socio-economic impacts.
The technology might be economical in a place like Japan, where natural gas prices are higher, he said.
