Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Carbon dioxide emissions, including emissions from developing, processing, and transporting the fuels, are shown in orange.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. There was no significant difference in the profiles of total carbonyl emissions between CFT and DF. Jakober, 2008). reduction in total carbonyls and a 6.0–100%
