Frequently Asked Questions About B100


Biodiesel is typically blended with petroleum diesel to achieve sustainability goals while keeping fleet performance strong. For example, B20 — a blend of 20% biodiesel and 80% ULSD — is growing in popularity.

But did you know your fleet could run on 100% biodiesel? Keep reading for answers to the most commonly asked questions about B100, its benefits, how it can significantly reduce emissions and protect your bottom line in the long run.

How does B100 work in a diesel vehicle?

A diesel vehicle can run on B100 year-round with an easy and affordable upgrade. An updated fuel storage system includes a split tank for petroleum diesel in one section and biodiesel in another. Diesel is used on start-up to prevent any cold flow issues. The system warms the biodiesel and automatically switches the truck to 100% biodiesel. At shut-off, the truck idles long enough to replace the B100 in the lines with diesel.

What infrastructure changes are required to run on B100?

Biodiesel fuel can be used in the same tanks and dispensing infrastructure as ULSD. However, fleets using B100 typically install a dedicated biodiesel tank because they still use petroleum diesel or biodiesel blends. REG can work with you to review existing infrastructure and determine whether any changes are needed.

What does B100 do for reducing emissions?

As you may know, a growing number of cities and states are mandating clean-air standards, and more fleets and their customers are setting sustainability targets of their own. Simply put: We need to do better now — not a few years down the road.

Biodiesel is one of the most effective fuels available for reducing harmful emissions. Take a look at the results from our best-in-class biodiesel:*

  • Emits 88% less CO2 than ULSD
  • Emits 85% less CO2 than compressed natural gas (CNG)
  • Emits 65% less CO2 than an electric vehicle on the average U.S. grid

Does it still perform well?

Yes! Biodiesel can give fleets some serious maintenance and performance advantages. Using B2 (2% biodiesel, 98% ULSD) provides more lubricity than required by the ASTM spec for diesel — so imagine how beneficial that lubricity becomes when you jump to B100.

Biodiesel also has a higher Cetane spec than ASTM’s requirement, so it provides a shorter ignition time. That means more complete combustion, which leads to more efficient engine operation. That cleaner burn also means less soot gets to the DPF, causing fewer regens and less wear.

Will I see a good ROI after investing in this technology?

You bet. The B100 system is affordable and only adds one new component that requires maintenance — a dedicated biodiesel filter — so the maintenance impact is minimal. As mentioned, biodiesel can actually offer improved maintenance attributes.

Also, biodiesel is priced competitively with diesel fuel. Altogether, the initial cost of switching to B100 technology is paid off fairly quickly. Plus, as sustainability plans and regulations spread, running on B100 could make your fleet a much more attractive partner to companies or organizations who need to reduce their environmental impact quickly.

What have B100 users said about it?

As more fleets test out different alternative fuels, B100 is getting some pretty strong reviews. Here are just a couple from our customers:

“Going to B100 with this particular technology is extremely practical for us. It’s a great first step as we get aggressive with our sustainability program. It works beautifully.”

— Rich Iverson, Fleet Support Manager, City of Ames, Iowa

“We were looking for a solution to maximize emissions reductions while minimizing any effect on operations.”

— Chris Geldart, Director, Washington D.C. Department of Public Works

How do I learn more or make the switch?

Biodiesel’s supply is strong, and it’s a simple modification to switch to B100. So why not start reducing emissions today? To see a B100 fleet in action, check out this video case study. Then, contact us at (844) 405-0160 or [email protected] to get started.
