$this->bbcode_second_pass_quote('sciencegirl', 'D')oes anyone know the EROEI of this technology ???
I didn't see it listed so it's probably not mind blowing, I would
imagine it would be similar to other oil shale technologies with the
added advantage of being applicable to areas poor in water
resources, which would be a big improvement over existing technologies.
A ball park guesstimate...
$this->bbcode_second_pass_quote('wiki', 'A') critical measure of the viability of oil shale as an energy source lies in the ratio of the energy produced by the shale to the energy used in its mining and processing, a ratio known as "Energy Returned on Energy Invested" (EROEI). A 1984 study estimated the EROEI of the various known oil shale deposits as varying
between 0.7–13.3[65] although known oil shale extraction development projects assert an EROI between 3 to 10. Royal Dutch Shell has reported an EROEI of three to four on its in situ development, Mahogany Research Project.[57][66][67] The water needed in the oil shale retorting process offers an additional economic consideration: this may pose a problem in areas with water scarcity.
