The new eco fuels generation made from waste fats from the food industry to rapeseed oil

Hydrotreated Vegetable Oil, that is: hydrotreated vegetable oil (or sometimes, in the hydrogenated version, that is to say hydrogenated). Nikname Hvo.
It is a type of fuel that is talked about a lot, even in the field of construction machinery and equipment. The concept is clear: they are fuels that, if used with diesel engines, mixed with the diesel itself or even pure, can reduce emissions by up to 90%.
Without the need to buy other expensive machinery, without modifications, and - at least in theory - without contraindications. We are talking about fuels because the origin raw materials may be different: from waste fats from the food industry to rapeseed oil.

In the first case a perfect recirculation is achieved, in the second one a collateral problem is created, that of subtracting land from agricultural crops to produce fuel. But, in a historical moment in which everyone is talking about ecological transition, and in which companies are watching the debate worriedly wondering how much it will cost, in what times, and above all who will pay for it, Hvo is a possible, immediate, available solution that you pay (more than diesel) according to consumption.

Does the use of HVO have any contraindications? This is to clarify and each engine manufacturer has its own technical interpretation. Some heat engine manufacturers are very optimistic, others less so. From September 2021 - for example - Liebherr-Werk Ehingen will be supplying its mobile crane and crawler cranes exclusively with pure HVO fuel. Not only on the latest models, but more generally on existing machines: according to the manufacturer, the use of recycled fuel is substantially free of contraindications and immediately at hand, as long as it respects the characteristics set by law.

We see growing customer interest in the use of HVO synthetic diesel. From our technical point of view - says Kohler - HVO is a stable fuel, which does not require modifications or additional maintenance to the engine. The FPT Industrial Stage V off-road engines, 2019 and 2020 launched, are compatible with HVO fuels. The Italian manufacturer aims to offer its customers sustainable solutions through compatibility with fuels that comply with the EN15940 standard.

For its engines, Yanmar specifies that “using a blend it is possible to stay within the parameters established by the EN590 standard. When instead it is used pure, the fuel refers to EN15940. In this case the fuels are less dense and have a lower calorific value than diesel. The engines are therefore compatible and using the HVO they do not fail, but it is likely that there will be a slight drop in performance ". These fuels can be a bridging solution for a transition to hydrogen, highly hybrid (range extender) or electric machine.
