PRAXAIR GREEN TECHNOLOGIES: LESS CARBON MORE GREEN
What if you could produce ultra-low sulfur diesel fuel while decreasing greenhouse gas impact?
Our study shows that the reduction in carbon dioxide equivalent (CO2-e) emissions enabled by ultra-low-sulfur-diesel (ULSD) used with diesel particulate filters is 15 times greater than the CO2 emitted in making the hydrogen required for ULSD.
The use of hydrogen to produce ULSD, together with a diesel particulate filter, enables a 16.2% reduction in CO2-e tailpipe emissions.
- Untreated diesel fuel carbon dioxide emissions = 12,042.6 grams per gallon
- The use of a diesel particulate filter significantly lowers black carbon emissions
- Reduction in carbon dioxide emissions = 1,951.2 grams per gallon
Total CO2-e reductions enabled by our hydrogen in the production of ULSD, along with the use of diesel particulate filters, more than offsets Praxair's direct CO2 emissions from hydrogen production.
