SAE Update - May 2022 - 25

technology development, Szybist noted,
particularly for the light-duty vehicle
sector responsible for 57% of transportgenerated
GHGs.
The sharpened focus on GHG emissions,
amid industry's shift to EV
development, prompted
SAE advanced-powertrain
committees to pivot their
annual High-Efficiency IC
Engines meeting toward
one incorporating
sustainable/renewablefuels
research discussions.
Hence the creation of
SLICE. The symposium's
main audience - fuels
experts, commercialdiesel
engineers,
combustion- and
aftertreatment-systems engineers, and
scientists from research universities and
the U.S. national laboratories - was
reflected in the packed meeting room on
April 4.
Life-cycle analysis (LCA) is playing a
significant role in both product and policy
planning, explained Dr. Michael Geller,
deputy director of the Manufacturers of
Emission Controls Association (MECA).
His SLICE keynote presentation,
" Integrated Approach to Mobile-Source
GHG Reductions, " highlighted the
industry's collective progress toward
meeting the Biden administration's GHG
reduction goals for 2030 (50-52% lower
UPDATE
than in 2005). " We're almost there, " he
observed.

Geller also clearly noted the challenges
and uncertainties facing the industry,
including the significant impact of gridCO2
intensity on
upstream GHG
emissions, the pace of
renewable-energy
power and EV battery
development, and cost.
While bullish on the
influence of increased
penetration of hybrids
and EVs on overall GHG
reduction, Geller, an
environmental engineer
and former EPA official
with deep experience in
GHG and particulate emissions, stressed
the challenge of electrifying transport
sectors beyond LDVs, particularly aircraft.
Biofuels from renewables, he said, " are at
the forefront " of GHG mitigation in
aviation.
Subsequent presenters at the 2022
SLICE detailed developments in hydrogen,
methanol, ammonia, synthetics and other
potential fuel solutions for largedisplacement
commercial ICEs, as the
drive to promote a lower carbon footprint
and lower emissions across all
transportation sectors gains steam. n
