UC Davis ITS report finds state transition to ZEVs will ultimately be cost-effective

California’s transition to zero emission vehicles (ZEVs) will begin to save the state money by as early as 2030, according to a study by researchers at the Institute of Transportation Studies at the University of California, Davis (ITS-Davis).

Although the transition will need to be rapid, and near-term costs and other barriers must be overcome, the report finds that reaching very low greenhouse gas emissions from road vehicles (cars and trucks) by 2050 appears feasible and ultimately cost-effective.

Zero emissions vehicle versus business-as-usual scenarios. The illustration shows that the initial higher vehicle costs over the next decade in the ZEV scenario are eventually repaid through lower fuel costs, particularly for electric vehicles. After 2030, the cost savings from operating ZEVs will offset their higher initial capital costs. This may also occur in the biofuel-dominated scenario, but may take longer to achieve.

Zero emission vehicles—which include both electric and fuel-cell cars and trucks—will be crucial to the transition to a low-carbon future. But there could also be an important role for advanced biofuels. In any case, strong policy support will be needed to ensure a full transition to these vehicles and fuels.

—lead author Lew Fulton, director of the Sustainable Energy Pathways Program at ITS-Davis

The report also found that a future scenario dominated by ZEVs would likely be more cost-effective than one that relies on advanced biofuels to reduce GHG emissions. In either case, the total costs over the next 30 years will likely be less than a business-as-usual scenario, and any near-term increases in cost would likely be small compared to the total that Californians already spend on vehicles and fuels.

Transportation is the largest source of CO2 emissions in California, as well as a major contributor to chronic air quality problems. Comparing potential strategies to make the transition to ZEVs, the ITS-Davis study modeled two major scenarios leading to the state target of an 80% reduction in road transportation-related greenhouse gas emissions by 2050. The scenarios incorporate emissions from passenger vehicles as well as relatively under-studied medium and heavy-duty trucks.

The first scenario considers a transition to ZEVs, primarily battery electric and fuel cell vehicles. The second scenario features fewer ZEVs, with very large growth in the use of advanced, mostly cellulosic-derived biofuels.

The study’s key findings include:

  • Attaining an 80% reduction in GHG emissions from heavy-duty trucks by 2050 is challenging but doable with a rapid ramp-up in ZEV truck sales.

  • Achieving significant GHG reductions in a purely ZEV scenario requires the state to find very low-GHG energy sources for hydrogen-fueled and electric vehicles.

  • Ramping up advanced biofuels can significantly reduce GHG emissions from internal combustion engines, giving policymakers leeway to pursue lower, more achievable ZEV sales targets for vehicle types such as long-haul trucks. However, the amount of advanced biofuels necessary to achieve these reductions may themselves prove challenging to produce sustainably.

To achieve a more ZEV-oriented transportation system, public and private investments will be needed between now and 2030. While upfront costs may be offset by reduced fuel consumption, strong policies will be needed to motivate the early- and mid-stage transitions and overcome early phase costs and other market barriers.

This study provides a foundation for deeper analysis of such policies and of specific technologies and pathways, the authors said.

Additional co-authors include Marshall Miller, Andrew Burke, Qian Wang, and Chris Yang of the UC Davis STEPS Program.

This study was funded by the STEPS/Energy Futures consortium.

While USA is producing more and more studies, China is producing and using many more e-vehicles than the rest of world ?

The economy and development have moved to Asia?

It is much easier to get a university to write a report than to get a trucker to buy a non existent e-truck.

Cleaner air in L.A. would be wonderful.

This is precisely why I have long been pushing a both-of-the-above strategy:  PHEVs using biofuels for their range extenders.  As a bonus, it radically reduces the amount of batteries required.

Sadly, most pols probably couldn't understand these tradeoffs even if they were explained in detail.  Just not smart enough.

Driving in LA we frequently see gross polluting heavy duty diesel trucks belching black smoke. If they where at least hybrid, they could greatly reduce the black smoke during heavy stop and go traffic. Always driving with recirculation on is not a long term solution.

FINALLY 35 YEARS LATER THEY MIGHT START TESTING THE WORST POLLUTERS!

Next important target is brake dust!

China doesn't need to convince a trucker of anything, they just announce a new policy.

A USA President could be impeached for a lot less?
