HYDROGEN AND ALTERNATIVE FUELS

Of the recent finding, initiative, or activity by your
organization, which most warrant mention for this
article?
AS: I'm very positive on fuels that don't add to the
carbon inventory-things like biofuels, renewable
fuels, e-fuels and other low-carbon fuels. These are all
dense energy carriers similar to their petroleum-based
counterparts that are often directly compatible
(fungible) with the existing fuel distribution
infrastructure (i.e., renewable diesel). It is my opinion
that these kinds of fuels, paired with hybrid vehicles
(full, not plug-in) would allow the fastest reduction of
CO2
emissions from the vehicle fleet-both new and
existing!
One MAJOR thing that I think often gets lost in the
UPDATE
discussion of the " electric vehicle
future " is the existing fleet-
alternative fuels such as the ones
listed above help them too! They
can be both forwards and
backwards compatible.
Ethanol is a great example of a
biofuel that can do just that-and
one that we have already been
using in our cars for around 20
years. Stellantis and Aramco are
working on e-fuels for this
reason, too.
Now, people might say: Why
would you make e-fuels rather
than use the (renewable)
electricity directly? Isn't that
more efficient? Perhaps.
However, the energy density
(and resulting mileage per tank/
equivalent) is often greater with
the e-fuels, they can be handled
and distributed like conventional
fuels, and this compatibility with
the existing infrastructure is a
huge benefit. I can point to what
Porsche is doing with e-fuels as a
potential model for other
companies to follow.
CS: The Italian National Research
Council (CNR) is involved in a
large number of collaborative
projects, both national and
international, related to
hydrogen and alternative fuels. I
