Cool Planet Energy Systems has it’s headquarter in Greenwood Village, Colorado, United states. Its proprietary process for conversion of biomass into biogasoline involves thermo-mechanical fractionation of biomass and catalytic treatment of the resultant volatile components. The biochar CoolTerra™ is the byproduct of the process. The company claims that it is able to produce 1 gallon of biogasoline with operating costs of $1.00 to $1.15.
The technology is flexible for biomass sources such as corn stover, wood chips and non-food energy crops such as miscanthus.
Cool Planet Energy Systems Technology
There are three stages in Cool Planet’s patented technology:
Pyrolysis of biomass
The dried biomass is passed through processing stations where it is subjected to heat and compacted mechanically. As a result a volatile stream consisting of useful hydrocarbons is produced. The non-volatile component of the biomass further undergoes heating at a higher temperature and compacting in the subsequent stages leading to extraction of the remaining volatile components.
In the next step the volatile components are subjected to a series of catalysts comprising a dehydration catalyst, an aromatization catalysts and a gas-upgrading catalyst. The main catalysts are proprietary modified ZSM-5 catalysts. The processes convert the useful volatile components into different types of fuels including high-octane gasoline blend stock. It is a drop-in replacement for automobiles and does not require changes in the existing conventional fuel infrastructure.
After the components useful for fuel have been taken out the leftover plant matter takes a solid carbon form called biochar. In 2013 Cool Planet announced the launch of its biochar soil amendment product ‘CoolTerra™ Biochar’. It enhances soil fertility owing to its quality of being highly porous and having good water and nutrient retaining capabilities.
Cool Planet Energy Systems has a pilot facility in Camarillo, California, while its first commercial scale plant is under construction at Alexandria, Louisiana. The company is expecting this 10-million gallon commercial-scale plant to become operational by the end of 2015.
Cool Planet Energy Systems plans to build two more refineries one in Natchitoches and another in Louisiana once Alexandria plant becomes operational.
