The EE-AGG Team is committed to creating value from waste CO2 by developing commercially successful enterprises. EE-AGG Team leaders were initially focused on creating value from CO2 waste streams generated in the biofuels industry. EE-AGG LLC was organized in 2013 as a Delaware joint venture company to commercialize proprietary technologies used to convert CO2 and other inputs into syngas which represents a platform for commercial conversion into a diverse array of more valuable products.
EE-AGG engaged Technip, Stone and Webster Process Technology Inc., Claremont, CA in 2013 to assist in providing a third-party technology engineering and economic feasibility study for proprietary processes involving multiple feedstocks, technologies, and products. EE-AGG has continued this relationship since the initial study was completed in 2014. Additional strategic partners and advisors are added when specialized expertise and capacity are required for developing successful pathways for commercial projects.
The EE-AGG Team seeks to meet carbon mitigation goals and maximize returns with a flexible portfolio of carbon capture and steam reforming technologies. Power plant flue stack CO2 is captured and combined with power generation (including renewable wind, solar, hydroelectricity), steam, natural and renewable gas, coal, and biomass (lignin) to produce syngas. Syngas is processed into renewable methanol and/or other high value products to sequester carbon in construction materials or plastics or cut vehicle emissions with cheaper, cleaner, higher-octane fuels.
EE-AGG captures CO2 from power plant flue gas using commercially available technology (such as Cansolv) to make a syngas, which is used to produce methanol using conventional technology. The CO2 to syngas step involves proven technology, such as steam-methane reforming. By adjusting the technology, other feedstocks can be added for syngas generation and range from methane, to coal, to renewables such as biomass or MSW. EE-AGG’s Carbon XPRIZE concept applies to both natural gas and coal-fired power plants depending on feedstock availability, and is carbon negative compared to current methanol production processes.
Methanol was selected as the initial product output because it is an energy carrier in liquid form and can be easily transported. Another benefit of this concept is co-production of power, which is made possible by the high level of heat integration among the various sections of the combined power-chemical complex. Since methanol is primarily used domestically in the United States as a chemical intermediate, the CO2 originally emitted to the atmosphere ultimately becomes sequestered in the form of adhesives and polymers, and other non-combusted products, which are commonly produced from methanol. Methanol can also be blended with gasoline to lower vehicle emissions and provides a high octane alcohol fuel and for an emerging global export market. In addition, other high value products such as DME, solvents, renewable oils, and waxes may be considered in the future.
