Sandvik’s Mobiles business unit and Cat dealer Finning say they have successfully tested hydrotreated vegetable oil (HVO) with C series Cat® engines without making any modifications to the engine or fuel tanks.

The test could pave the way for the renewable synthetic diesel powering large, mobile crushing and screening equipment from Sandvik, the OEM said.

Forming a part in both company’s journey towards a more sustainable future, the use of HVO reduces net carbon emissions by up to 90% compared with conventional diesel, the companies say, with the HVO used by the companies only made from renewable feedstocks certified by The International Sustainability & Carbon Certification.

Its performance is similar to regular diesel, so the power output and uptime are not compromised, according to the companies.

The companies explained: “Hydrotreating of vegetable oils is a modern way to produce very high-quality renewable diesel fuels without requiring any changes to fuel logistics, engines, or exhaust aftertreatment devices. Unlike other biodiesels, HVO is not sensitive to low or high temperatures, or indeed to exposure to sunlight, as all oxygen is removed during the production process. Also, due to the use of hydrogen in the production process, HVO has an impressive shelf life, compared to other biodiesels. Since no iron or system changes are required, it can be considered a drop-in replacement for diesel.”

Jesper Persson, Vice President Life Cycle Services at Sandvik Mobiles, said: “We are committed to using engineering and innovation through our products to make the shift towards more sustainable business. With a host of innovations in the pipeline, including electrification of our offering, we are excited to be pioneers in the industry and invest in renewable fuel sources sustainable rock processing solutions.

“Working alongside Finning to performance-engineer the feasibility of HVO means we can collect data and monitor any impact on the performance and output. It’s an exciting step in our contribution to sustainability and we will work together with our customers and suppliers for more productive, safer, and innovative solutions.”

Steffen Barrett, Sales Manager – Industrial Engines, Finning UK & Ireland, said: “As Sandvik strive to balance environmental and business sustainability, we are ready to provide the solutions they need to achieve their goals. Our customers’ priorities are evolving toward a carbon-reduced future and our products and services are evolving with them.

“We are actively supporting the use of plant-based and waste-derived fuels in our engines as alternatives to traditional fuels. Our engines are engineered for use with a range of renewable fuels, including up to B100 HVO (EN15940 or ASTM D975), that have a significantly lower net carbon footprint than conventional diesel.”
