Friday Seminar - Joan Ogden on Alternative Fuels

Hydrogen Fuel Apparatus

Tomorrow's TRANSOC Friday Seminar is with Joan Odgen of the UC Davis STEPS program presenting, "Transitions to Alternative Fuels: Comparing H2, Electricity, and Biofuels":

We analyze and compare alternative scenarios for adoption of new light duty vehicle and fuel technologies that could enable deep cuts in gasoline consumption and GHG emissions by 2050. We also estimate the transitional costs for making new vehicle and fuel technologies economically competitive with gasoline vehicles. We estimate future GHG emissions and gasoline use for the following scenarios:

·  Efficiency—Currently feasible improvements in gasoline internal combustion engine vehicles (ICEV) and hybrid electric vehicles (HEV) technology are introduced.

·      Biofuels—Large-scale use of low-carbon biofuels is implemented.

·      PHEV success—Plug-in hybrid electric vehicles (PHEVs) play a major role beyond 2025.

·      HFCV success—Hydrogen fuel cell vehicles (HFCVs) play a major role beyond 2025.

·      Portfolio—More-efficient ICEVs+biofuels+PHEVs+HFCVs implemented in various combinations.

All scenarios assume the same total number of vehicles and vehicle miles traveled, but the vehicle mix over time is different for each scenario. We compare each scenario to a reference scenario where modest improvements in efficiency take place and use of biofuels increases but no electric-drive vehicles are implemented. We also explore transition dynamics using a “learning curve” model, and estimate the cumulative investments that would be required to bring new technologies to “breakeven” with gasoline ICEV technologies.  Finally, we suggest future work to better understand transition costs.

The seminary will be this Friday, Septermber 9 2011, from 4-5 p.m. in 406 Davis Hall. Don't forget about Cookie hour before hand at 3:30 in the library. See you there!

Fuel-Economy Standards to Double by 2025

This morning in Washington D.C., away from the debt ceiling debate, President Obama spoke about raising fuel efficiency standards. On stage with auto industry executives, he laid out his plan:

And today, these outstanding companies are committing to doing a lot more.  The companies here today have endorsed our plan to continue increasing the mileage on their cars and trucks over the next 15 years.  We’ve set an aggressive target, and the companies here are stepping up to the plate. 

By 2025, the average fuel economy of their vehicles will nearly double to almost 55 miles per gallon.  (Applause.)  So this is an incredible commitment that they’ve made.  And these are some pretty tough business guys.  They know their stuff.  And they wouldn’t be doing it if they didn’t think that it was ultimately going to be good business and good for America. 


Using less oil also means our cars will produce fewer emissions.  So when your kids are biking around the neighborhood, they’ll be breathing less pollution and fewer toxins.  It means we’re doing more to protect our air and water.  And it means we’re reducing the carbon pollution that threatens our climate.

The President took time to thank California for leading the charge for better fuel efficiency in vehicles. You may remember when the state sued the EPA in 2008 over emissions rules where Federal standards did not meet the aggressive targets of AB 32
