Why Biodiesel Is Also a Technically Strong Alternative to Fossil Diesel

• Technically equivalent – and superior in key aspects: Ignition quality, lubricity, and soot behavior clearly support the use of modern FAME biodiesel in everyday operations.
• Minimal operational differences: While neat biodiesel has a slightly lower energy content, real-world data show only marginal increases in fuel consumption and negligible performance deviations. In common blends such as B10–B20, differences are typically not noticeable.
• Immediate impact in the existing fleet: Biodiesel can be deployed within existing infrastructure, reducing emissions without requiring short-term fleet replacement or retrofitting.

In discussions about climate-friendly mobility, the debate is often framed as a binary choice: fossil or fully electric. In reality, the most immediate lever available to Europe and Austria in the transport sector lies in the existing fleet. Millions of vehicles, machines, and commercial transport units are in operation today – and will remain so tomorrow. This is precisely where solutions are needed that deliver immediate impact, are reliably available, and integrate seamlessly into established logistics and supply systems.

Biodiesel is one such solution. It is no longer a niche product, but a technically mature fuel that complies with modern standards and has been successfully deployed for years in fleets, municipalities, agriculture, and logistics. Nevertheless, a persistent myth remains: that biodiesel offers lower performance and creates operational challenges. The technical reality tells a different story.

“We need to return to fact-based evaluation when discussing biodiesel – ignition behavior, lubricity, and winter operability. Modern biodiesel grades are technically reliable and can be deployed immediately within the existing fleet. That makes them a central building block for rapid emissions reduction,” says Ewald-Marco Münzer, CEO of Münzer Bioindustrie.

Technically Mature and Field-Proven

Biodiesel performs convincingly in direct technical comparison. Its high cetane number ensures reliable ignition and smooth combustion. Although biodiesel has a lower energy content than fossil diesel, the practical implications are moderate. Even when used as neat fuel, additional consumption typically remains in the low single-digit percentage range. In common blends such as B10 or B20, operational differences are generally negligible.

Another advantage is its excellent lubricity, which can reduce wear on sensitive engine components and positively influence maintenance intervals and service life. Concerns about cold weather performance have likewise been addressed: standards-compliant biodiesel, combined with appropriate additives, ensures reliable operation under Central European winter conditions.

The Next Step: Expanding Effective Blending Options

If Austria aims to meet its transport climate targets efficiently, it requires not only long-term structural measures but also scalable short-term solutions. From Münzer’s perspective, a pragmatic next step is the further development of existing blending models – for example, gradually enabling higher blend levels where vehicle technology, standards, and fleet experience support such use. At the same time, renewable fuels must be treated on equal technological footing in procurement and tender processes to ensure fair consideration in municipal, public, and commercial fleets.

“Transport systems will not be rebuilt overnight. But we can rapidly reduce the fossil share within the existing fleet – provided we do not downplay market-ready solutions, but deploy them intelligently,” Münzer concludes.
