Yeah, yeah.
Maybe material incompatibility issues as well:
- replace rubber fuel lines & seals
- heated fuel tank for BD
Some of the "disasters" blamed on BD really
were the result of one of its virtues: good solvent;
cleaned out residue from tanks and fuel lines ---->
clogged filters.
The BD I used in the diesel that I ran year round
was "treated" with winterized petro diesel, 30-40%
petro when it got below 30F. That, and a block heater
and it ran in cold weather.
I like the feedstock, all co-products, "wastes" of other industries.
- USED veg oil
- oil from ethanol industry (fermentation does not
involve the oil; can be pressed out prior to fermentation and
used).
- rendered animal fat; but will have a high gel point

Sounds like they are installing a dual tank system to allow starting
on
diesel then switching to biodiesel later to prevent jelling issues.
If it
were just running on biodiesel in weather above 30F or so, my
typical
proceedure is just to have a few spare fuel filters handy.....
usually
somewhere in the $10 to $50 each range, not $7500....

[So, what do you need to do to a diesel truck to run it on biodiesel
which
costs $7,500 per truck? And how much green fuel do you have to burn
to
save more than $7,500 per truck, so it will actually save the city
money,
when petro-diesel is selling for less than $3 a gallon? This site (
http://www.altfuelprices.com/stations/BD/Pennsylvania/Pittsburgh/)
says
this station (http://www.bbapgh.com/) is selling biodiesel at $5.29
a
gallon. I guess that depends on how much the state alt fuel grants
are
paying.]
Pittsburgh to Run City Trucks on Biodiesel
Posted on February 19, 2015 by John Davis
The City of Pittsburgh soon could be running some of its trucks on
biodiesel. This article from the Pittsburgh Post-Gazette says a
proposal is
before the city council to enter into a $150,000 agreement with
Optimus
Technologies to convert about 20 Department of Public Works trucks
to run
on the green fuel, which will reduce emissions and save the city
money.
Grant Ervin, the city’s sustainability manager, said Optimus’ Vector
fuel
system was tested on five municipal trucks in a pilot program that
started
in 2013. The goal is to add it to other city vehicles as an analysis
of the
city’s fleet needs continues.
“That’s what really exciting about it,” Mr. Ervin said, adding that
part
of the cost of the program will be covered by state alternative fuel
grants. “For us, it’s a tool we can extend to other vehicles. … What
the
Optimus technology does is basically create hybrid vehicles.”
In cold weather, when biofuel can be plagued by “gelling,” the
trucks can
be started on conventional diesel fuel and switched to biofuel when
it
warms up, said Optimus CEO Colin Huwyler.
The biodiesel that could be used would be made from recycled cooking
oil,
non food-grade corn oil from the ethanol industry and rendered
animal fat.
