Iowa’s First Retail B99 Biodiesel Site Opens with Benecor’s Cold-Climate Fuel Infrastructure Solution

February 21, 2026

Project Overview: High-Blend Biodiesel in a Cold-Weather Retail Environment

In Spring 2025, Iowa’s first retail B99 biodiesel pump officially opened at the Pilot Travel Centers location in Urbandale, Iowa, between Douglas Avenue and Interstate 35 near Des Moines.


The site is one of the first in the United States to offer B99 biodiesel (99% renewable biodiesel) at a retail pump — expanding access to high-blend biofuels for commercial fleets operating across central Iowa.

But launching a B99 retail fueling site in the Midwest required more than just adding a pump.

It required solving a cold-weather infrastructure challenge.

Why B99 Is Difficult in Cold Weather



  • Biodiesel has a higher cloud point than petroleum diesel
  • It can begin to crystallize or gel at temperatures well above freezing
  • Thickened fuel can clog filters, restrict flow, and damage dispensing equipment
  • Above-ground tanks are exposed to ambient winter temperatures


Historically, many high-blend biodiesel systems relied on underground storage tanks (USTs) to leverage the earth’s stable temperature. But for retrofit travel center projects, underground installation can be:

  • Cost-prohibitive
  • Operationally disruptive
  • Logistically impractical


The Urbandale site needed a solution that could support year-round B99 retail sales — without requiring new underground infrastructure.

Benecor’s Solution: Engineered Above-Ground Biodiesel Infrastructure


Benecor designed and manufactured a fully integrated, temperature-controlled, above-ground biodiesel storage and dispensing system engineered specifically for cold-climate operation. Instead of relying on underground tanks, Benecor developed a turnkey above-ground system that maintains fuel integrity in freezing conditions.


The System Included:

  • Fully insulated above-ground storage tanks engineered to minimize heat loss
  • Integrated heating systems and temperature controls to maintain biodiesel above critical cloud and gel points
  • Heated piping, pumps, and dispensing components to ensure uninterrupted fuel flow


The entire system was engineered and manufactured in Michigan, then delivered and installed as a turnkey solution tailored to the specific operational demands of high-blend biodiesel in a Midwestern retail fuel environment.

Why On-Site Blending Matters for Fuel Retailers

According to Benecor Owner Brendan Foster:

“We’re talking to other folks out there who are also asking how they can get the higher biofuel rates. On-site blending means we’re able to provide a fairly inexpensive approach for the Pilots of the world to take advantage of available credits and offer now another outlet for biodiesel.”

By integrating blending capability within a heated, insulated above-ground system, Benecor enables:

  • Access to renewable fuel credits and incentives
  • Flexible fuel blending without additional underground tanks
  • Protection of fuel quality in cold climates
  • Scalable infrastructure for future biofuel expansion


For travel centers and fleet fueling operations, this means lower installation complexity, controlled capital costs, and reliable year-round biodiesel availability.

The Result: A Scalable Model for Cold-Climate Renewable Fuel Deployment

The Urbandale project demonstrates how engineered system design can overcome the cold-weather limitations traditionally associated with high-blend biodiesel.


With Benecor’s purpose-built storage, blending, and dispensing infrastructure, the Pilot Travel Centers site now serves as a real-world model for:

  • Retail B99 biodiesel deployment
  • Cold-climate above-ground fuel storage
  • Scalable renewable fuel infrastructure
  • Commercial fleet biofuel adoption


State and agricultural leaders recognized the opening as a milestone in strengthening Iowa’s renewable fuel supply chain — connecting soybean production to lower-carbon transportation solutions at the retail pump.

Introducing the BENECOR® Lite Duty-Series: Smart, Economical DEF Solutions for Modern Fleets

By Amber Crawford • March 18, 2026
Benecor is proud to introduce our new Lite Duty line—designed with our customers in mind. This launch marks just the beginning, with more cost-effective, high-quality solutions on the way. We listened, and we’re delivering—bringing a new range of economical products to market without compromising performance or reliability. Stay tuned for what’s next.  For fleet operators, efficiency and reliability aren’t just goals—they’re necessities. Managing Diesel Exhaust Fluid (DEF) storage and dispensing shouldn’t add complexity or cost to your operation. That’s where the BENECOR® Lite Duty-Series DEF Dispensing & Storage Systems stand apart: delivering proven performance, simplified installation, and exceptional value in one rugged, purpose-built solution. Built for Fleet Efficiency The Lite Duty-Series was engineered with fleet customers in mind. These systems provide a dependable and cost-effective way to store and dispense DEF in both indoor and outdoor environments. Whether you’re managing a small fleet or scaling operations, the Lite Duty-Series offers a practical solution that balances performance with affordability. DEF presents unique challenges—especially in colder climates where it freezes at 12°F (-11°C). To address this, BENECOR offers an optional cold-weather package that helps maintain system integrity and ensures consistent operation, even in the harshest winter conditions. Compact, Island-Friendly Design Space is often limited in fueling environments. That’s why the 400- and 600-gallon Lite Duty-Series systems are designed to fit seamlessly on a standard 4-foot fueling island. This compact footprint allows fleets to integrate DEF dispensing directly into existing layouts without costly site modifications. Plug & Pump Simplicity When it comes to installation, speed and simplicity matter. BENECOR’s Plug & Pump design delivers a true turnkey solution: Position the system at your site Connect power Fill with DEF Start dispensing No complicated setup. No extended downtime. Just fast, efficient deployment that gets your operation moving. Reliable Construction, Lower Costs Durability meets value in every Lite Duty-Series system.
