We’re Charging Our Cars Wrong

Cars That Think

The operators who own these charging stations have said it as well, and they also cite the high cost of equipmenta DC fast-charging station with four ports can cost between US $470,000 and $725,000. If equipment costs were lower, they say, they would install more recharging stations. The answer is yes, and heres why.

NREL team shows wafer cost of gallium oxide can be >3× lower compared to SiC; 2x lower cost for power electronics

Green Car Congress

A team from the National Renewable Energy Laboratory (NREL) has shown by modeling that the wafer cost of an emerging Ga 2 O 3 wide bandgap semiconductor can be more than 3-times lower compared to SiC. This lower cost of the Ga 2 O 3 wafers should lead to less-expensive high-performance power electronic devices in the future.

DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. Skaggs et al. demand in 2016.

By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. Conversion of iron ore into iron accounts for 90% of steelmaking emissions that may be eliminated using Electra’s process.

mgPt cm -2 ) is shown for comparison (dashed line). The prohibitive cost of platinum for catalyzing the ORR has hampered the widespread use of polymer electrolyte fuel cells. For all intents and purposes, this is a zero-cost catalyst in comparison to platinum, so it directly addresses one of the main barriers to hydrogen fuel cells.
