Direct CO2 to Methane Conversion Using Affordable Catalysts?

10/21/2016 8:55 AM

This is WAY outside my box.

Would anybody be willing to comment on the significance of this?

Methane ≠ methanol.

Electricity provides the energy to separate the Carbon and Oxygen in the CO2 with a 63 percent efficiency with the end product being ethanol, C2H5OH. When this ethanol is burned as fuel (or consumed ), the CO2 is returned to the atmosphere.

So, what it boils down to is, with some loss of efficiency, the energy of electricity is being transferred to the end user. Whether this results in reduction of CO2 emissions all depends on how the electricity is generated, by fossil fuel burning or by other processes, i.e., nuclear, solar, wind, or hydroelectric.

Don't get your shorts in a bunch.

Like so many other "save the world" revolutionary new discoveries this may not amount to much over the long haul.

I didn't get into the first discussion, mostly because I had to buy the beer and also I have no clue.
