Reduce CO2 levels by pre-industrial time in 10 years?
The STEP process uses energy and solar heat to collect CO2 just published by US scientists. Using sunlight to power electrolyte cells to separate CO2, while using solar heat to heat cells to reduce the energy required for conversion.
Thus, with the method of using sunlight and solar heat to absorb and convert CO2 from the air, it can clean the atmosphere and at the same time produce fuel for machinery.

The key advantage of this new solar energy collection process is the simultaneous use of light and solar heat.While solar heat is often considered to be disadvantageous because it is possible to make degraded photovoltaic materials, the new method uses that heat to convert more solar energy into carbon than just using it alone. photovoltaic or photovoltaic process.
The new process is called electrochemical and solar thermal carbon collection, or STEP for short.This is the first and only process to use light and solar heat simultaneously to absorb carbon.This process was submitted theoretically and recently described by a group of scientists from George Washington University and Howard University and described in the journal The Journal of Physical Chemistry first.
According to Phyorgs, Professor Stuart Licht - GS of Chemistry at Washington University, although CO2 is an unreacted compound and is often difficult to be removed, it can still be easily absorbed by using solar energy in the process. STEP lithium carbonate electrolytic salt.Professor Stuart Licht believes that this process will reduce the amount of CO2 in the atmosphere by the pre-industrial period within 10 years.

According to the scientists' explanation, the process of using sunlight to power electrolyte cells to separate the CO2, while using solar heat to heat the cell to reduce the level The energy needed for the conversion process.Electric cells separate CO2 into liquid carbon (when the reaction occurs at temperatures between 750 and 850 degrees C) or CO (when the reaction occurs at temperatures above 950 degrees Celsius).
Experiments of the study show that this technique can absorb and convert energy-saving CO2 to 34-50% thanks to the use of solar heat.Besides carbon that can be stored, scientists also use CO and hydrogen generated in the STEP process to separate water to synthesize diesel and gasoline fuels.
