More Japan CO2 Recycling

 

Advanced materials for global carbon dioxide recycling
 
We herein present more, with more to follow, on Japanese proposals to recycle the CO2 by-product of our coal use.
 
Notable, we think, in these Japanese studies, is the fact that so many researchers, and so many institutions, are putting their names on these reports. Given Japanese culture, it must be a point of honor with them. They are standing together to make public a concept and a technology they know to be true and viable, in the face of mass ignorance and blind opposition.

Abstract

CO2 emission increase inducing global warming occurs mostly with the growth of the economic activity. Global CO2 recycling can prevent global warming and supply abundant renewable energy. Global CO2 recycling consists of three district: The electricity is generated by solar cells on deserts. At coasts close to the deserts, the electricity is used for hydrogen production by seawater electrolysis and hydrogen is used for methane production by the reaction with CO2. Methane (CH4) is liquefied and transported to energy consuming districts where after CH4 is used as a fuel CO2 is recovered, liquefied and transported to the coasts close to the deserts. Key materials necessary for the global CO2 recycling are the anode and cathode for seawater electrolysis and the catalyst for CO2 conversion. All of them have been tailored by us. Amorphous and nanocrystalline nickel alloys are active cathodes for hydrogen production in seawater electrolysis. Anodically deposited nanocrystalline Mn–Mo and Mn–W oxides are the unique substance which can evolve oxygen with 100% efficiency without evolving chlorine in seawater electrolysis. Amorphous Ni–Zr alloys are excellent precursors of catalysts for conversion of CO2 into CH4 by the reaction with hydrogen at 1 atm. A prototype CO2 recycling plant to supply clean energy preventing global warming has been built on the roof of our Institute (IMR) in 1996 using these key materials and has been operating successfully."

Methane is reasonably useful stuff in it's own right, but can be, as we've previously documented, transformed through various catalytic procedures into more complex hydrocarbons, including liquid fuels.
