After thorough evaluation of the above noted DCL and ICL technologies, the ExxonMobil/Accelergy DCL (EDS/MCL) technology was selected for the following key reasons:
- It provides up to 50% greater yields at significantly lower capital costs than other traditional coal conversion processes
- Although individual ICL processes can produce a wide product mix, no single ICL process can produce synthetic jet, diesel, and gasoline with the same originally installed equipment like the ExxonMobil/Accelergy process can
- It has a 50% lower CO2 footprint when compared to other CTL technologies, resulting in lower sequestration requirements when the CO2 is not being sold for enhanced oil recovery operations. The CO2 footprint may be further reduced by adding beneficial hydrogen from possible neighboring coal-bed methane fields or from possible underground coal gasification
- A 1,000 BOPD plant has been built and operated for three years and performed as expected with the desired product yields, product quality, and operating performance
- The liquefaction process is operationally flexible and can produce Jet, Diesel, and/or Gasoline with the same originally installed equipment
