arbcombo -- Draft Medium- and Heavy-Duty Fuel Cell Electric Vehicles Technology Assessment Released for Public Comment

Posted: 18 Nov 2015 08:27:44
The California Air Resources Board (ARB or Board) announces the
release of the draft document “Technology Assessment: Medium- and
Heavy-Duty Fuel Cell Electric Vehicles”. 


This draft technology assessment identifies the status of fuel
cell electric vehicle technology for Class 2b through Class 8
vehicles (gross vehicle weight ratings of 8,501 pounds and up). 
The draft assessment describes the potential for emission
reductions, the market penetration of fuel cell electric
drivetrain in medium-duty and heavy duty trucks and buses, and
the next steps for achieving these emission reductions from fuel
cell electric vehicles.  Sources of information used in the draft
assessment include an extensive list of published reports and
research papers.  

The draft technology assessment can be viewed and downloaded from
the ARB’s technology and fuels assessment webpage at: 
http://www.arb.ca.gov/msprog/tech/report.htm.

We encourage interested parties to submit comments on the draft
technology assessment through the technology and fuels assessment
web page for public comments at:
http://www.arb.ca.gov/msprog/tech/techreport/comments.htm.  
We prefer to receive comments within 30 days of the posting of
this draft assessment, if possible.  

ARB staff will provide an informational update to the Board on
this draft technology assessment, along with the draft technology
assessments for hybrid and battery electric heavy-duty vehicles,
at the November 19, 2015, Board meeting in Sacramento.  The
public agenda can be accessed at: 
http://www.arb.ca.gov/board/meetings.htm. 

If you have questions regarding the draft technology assessment,
please contact Dr. Marijke Bekken, Staff Air Pollution
Specialist, at 916-322-8987, or at marijke.bekken@arb.ca.gov.


Background:  California has made substantial progress in reducing
emissions from mobile sources, but further reductions are needed
to meet California’s air quality and climate goals.  These goals
include:

•Meeting 2023 and 2031 ambient ozone air quality standards, which
staff estimates will require an overall 80 percent reduction in
NOx emissions below today’s levels in the South Coast air basin,
with substantial reductions needed in the San Joaquin Valley and
other non-attainment areas of the state as well;

•Meeting the newly proposed federal ozone standard;

•Reducing greenhouse gas (GHG)  emissions to 1990 levels by 2020;


•Achieving a 40 percent reduction in GHG emissions from 1990
levels by 2030;

•Achieving an 80 percent reduction in GHG emissions from 1990
levels by 2050;

•Reducing petroleum use in cars and trucks by up to 50 percent by
2030; and

•Producing at least 50 percent of electricity from renewable
sources by 2030.  

Heavy-duty vehicles greater than 8,500 pounds emit about
one-fifth of the total GHG emissions associated with
transportation sources in the State, which is about eight percent
of the statewide total. In addition, these vehicles account for
33 percent of NOx emissions from all statewide sources.  Because
trucking emissions are such a significant source of GHG and
criteria pollutant emissions, achieving reductions within the
trucking sector is a key component in the strategy to meet
California’s climate and air quality goals.

The technology assessments were prepared by staff from ARB, along
with staff from the South Coast Air Quality Management District. 
They were discussed at workshops in September 2014, and at the
December 2014 ARB board meeting.  More information on the
assessments is available at ARB’s website at
http://www.arb.ca.gov/msprog/tech/tech.htm.  An overview of the
technology assessments was released in April 2014 and is
available on ARB’s website at
http://www.arb.ca.gov/msprog/tech/report.htm.
