note the potential of each technology and explain what advances must occur with each if they’re ultimately to be deployed. High discharge rates or high current densities are important, although the state-of-charge (SOC) of the storage system typically will not move over a wide range. In their study, Yang et al.

Major study concludes achieving EU 2050 transport decarbonization goals will require portfolio of advanced powertrains; fuel cells, battery-electric and plug-in hybrids

Green Car Congress

The consortium considered it particularly important to re-assess the role of FCEVs in the light of recent technological breakthroughs in fuel cell and electric systems that have now increased their efficiency and cost-competitiveness significantly. Charging times are also significantly longer: 6-8 hours using normal charging equipment.

In Li-ion batteries, Li ions (Li + ) leave the cathode during charging and move through the electrolyte and separator to intercalate into the anode. As the technology gets fixed, the anode is more of an issue related to fast charge. and re-evaluate their expectations for range. The reverse happens on discharge. Click to enlarge.

ITF report finds self-driving shared vehicles could take up to 90% of cars off city streets; total kilometers travelled increases

Green Car Congress

If a fleet of electric vehicles were used instead, a fleet of shared self-driving vehicles would need only 2% more vehicles, however, to accommodate battery re-charging times and reduced travel range. However, overall vehicle-kilometers travelled during peak periods would increase in comparison to today.
