Electricity with CO2 Recycling

 
 
The enclosed report introduces yet more information detailing how technologies for our use of coal can be fully integrated to generate power and synthesize liquid fuels concurrently, and reduce emissions of Carbon Dioxide as a productive function of the overall process.
 
Other references detailing these developments are available, and we will attempt to summarize the import of this technology following the excerpt:

Abstract

To reduce the emission of CO2 into the atmosphere, two schemes are proposed. The first one is a coal-fired MHD-steam combined power generation system where coal is burned with oxygen rather than air, the obtained high temperature is utilized for the MHD generator and the CO2 is liquefied and recovered. The cycle efficiency with CO2 recovery is estimated to be 45.3% (HHV). Another scheme is a combination of liquid fuel production and MHD-steam combined system, where the CARNOL processes of methanol production are used to reduce CO2 emission from sectors where collection of COI is otherwise impossible, such as highly dispersed heat engines and small scale fuel users. The carbon produced from the CARNOL processes is used as a fuel for the MHD-steam combined cycle, and CO2 is liquefied and recovered. 56.2 kg/sec of methanol is produced while the net power delivered to the grid is 370.7 MW, 42.2 kg/sec of CH4 is consumed."
 
First of all, "MHD" abbreviates "Magnetohydrodynamic", a mouthful, which denotes the technology of generating electricity by passing a mixture of gases, ionized by high temperature, through a magnetic field.
 
In this concept, that gas arises from coal combustion. And, after MHD power generation, the Carbon Dioxide in the gas used for that electricity generation is collected and converted, via the Carnol technology we've previously documented, into the liquid fuel and gasoline raw material, Methanol.
 
However, the Abstract is so abbreviated that what isn't clearly explained is the associated concept that CO2 can be collected from smaller sources of emission, as well, and also converted into liquid fuel. Unmentioned are the logistics of how the economics of a dispersed collection network would play out, but, certainly, for major CO2 emitters, such as coal-fired power plants, the concept could be feasible and practical, especially if other, mandated, costs, such as Cap & Trade and Sequestration, were thus eliminated.
