670% population increase, 1,65,000% CO2 emissions increase between 1800 and 2020

December 30, 2023 by Narasimhan Santhanam Director - EAI

670% population increase, 1,65,000% CO2 emissions increase between 1800 and 2020 1800 is whenabouts that the climate change folks refer to as pre-industrial times, and CO2 emissions, cumulative CO2 levels and global temperatures are benchmarked with those during that time period (idea is to keep down global emissions so we...

Does our breathing contribute to climate change?

December 30, 2023 by Narasimhan Santhanam Director - EAI

Does our breathing contribute to climate change? A human adult breathes out 1 Kg of CO2 a day, so that would be about 7 million tons of CO2 for the entire world population, and 2.6 billion tons per year (with adjustments made for babies and very old people). 2.6 billions...

Rock dust – an unlikely decarbonization hero

December 30, 2023 by Narasimhan Santhanam Director - EAI

Rock dust - an unlikely decarbonization hero Spreading rock dust on farmlands could capture two billion tons of CO2 per year, says a study. In principle, that should not be surprising. Rock materials, during the weathering process, capture CO2 and convert it into carbonates and sequesters it for a very...

Plasma based CO2 conversion process, through low temperature plasma

December 30, 2023 by Narasimhan Santhanam Director - EAI

Plasma based CO2 conversion process, through low temperature plasma Plasma, the “fourth state of matter,” is an ionized gas comprising electrons, ions, radicals, excited atoms, and molecules. It presents a highly reactive environment, lending itself to different applications. In the context of CO2 conversion too, there is increasing interest in...

 CO2 to durable thermoplastics – neat

December 30, 2023 by Narasimhan Santhanam Director - EAI

 CO2 to durable thermoplastics - neat My grandma would use a durable plastic container for a very long time - so long that all her plastic containers outlived her presence at home. And without ever having come across the term decarbonization (or carbon for that matter, bless her simple soul),...
