States With Highest Portion Of Their CO2 Emissions Coming From Transportation: California, Washington, & Hawaii

CleanTechnica EVs

This is an interesting use of data for a state comparison. Energy Information Administration has created a map showing what portion of the 50 US states’ CO2 emissions come from transportation (as of 2018*). As you can see above, states in the West and Florida (and Vermont) had the highest portions of their […].

of global CO2 emissions. In comparison, a container vessel carrying thousands of TEU sailing from Panama to Rotterdam makes around 8,800 km. To achieve this goal, carbon neutral vessels must be commercially viable by 2030, and an acceleration in new innovations and adaption of new technology is required.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. Partially because of this heat, the Brayton cycle has the potential to be much more efficient at turning heat from power plants—nuclear, natural gas or even concentrated solar—into energy than the traditional steam-based Rankine cycle.

Cummins and Tula study of Diesel Dynamic Skip Fire (dDSF) shows 74% reduction in NOx, 5% in CO2 on low load cycle

Green Car Congress

In comparison with current engine technologies and modifications to the thermal management techniques, dDSF saved 20% in fuel, validating dDSF as a more fuel-efficient means of reducing NO x. This system showed a 74% reduction in NO x and a 5% reduction in CO 2 compared with today’s clean diesel technologies.

Kobe Steel to launch “Kobenable Steel”, Japan’s first low-CO2 blast furnace steel

Green Car Congress

In comparison to the blast furnace method, the MIDREX Process can reduce CO 2 emissions by 20 to 40%. The MIDREX Process uses natural gas as the reductant and pellets made of iron ore as the source of iron to make DRI through the reduction process in the shaft furnace.

JATO: European new car CO2 emissions highest average since 2014; shift from diesel to gasoline and SUVs rise

Green Car Congress

The analysis covered 23 markets in Europe and found a direct correlation between diesel car registrations and average CO2 emissions. The total value of CO2 emissions was on a steady decline from 2007, but started to slowdown in 2016 as the fall reduced from -4.1 g/km to 120.5 —Felipe Munoz, JATO’s global analyst.
