Green Diesel and Eni Diesel +

The story from close up

Our latest breakthrough in the field of fuel is Green Diesel, the result of innovative Ecofining™ technology developed in partnership with Honeywell UOP. Obtained from the hydrogenation of vegetable oils, it has improved features compared with traditional biodiesel. The new component is produced in Eni’s Venice biorefinery – the world’s first example of the “bio” conversion of an existing refinery – and, when added to diesel, creates Eni Diesel+ .


Thomas tells us how Eni Diesel+ was born. The researcher from the Downstream Process Technologies sector takes us on a journey through the Research Centre Laboratories in San Donato Milanese and explains how the biorefinery in Venice created a 100% renewable product, Green Diesel, thanks to the Ecofining process.


Silvia, technical leader of the characterisation of raw materials, fuels and blending in the downstream product technologies sector talks about the agreement between Eni and the Italian Navy to test a biofuel composed of at least 50 per cent Green Diesel. After many tests in the laboratories of the San Donato Milanese Research Centre came an unforgettable experience at sea.


Straight from the engine and emissions testing labs of our research centre, Giammarco Gioco describes how these new Eni diesels, petrols and lubricants take shape, while Corrado Fittavolini explains how Eni Diesel+ recorded a reduction of up to 40 per cent in emissions in Euro 4, Euro 5 and Euro 6 vehicles.

What more does it have?


What more does it have?

It reduces polluting emissions, is the result of a more sustainable production process and helps to reduce CO2 emissions by an average of 5 per cent.

What will happen in 2020?


What needs to happen by 2020

Green Diesel is the first important step towards more advanced formulations that comply with or even anticipate stringent Italian and European legislation on biofuels. Thanks to its constant commitment to research and innovation in the world of fuels, Eni is preparing to face upcoming commitments set by the European Commission, including the reduction of greenhouse gas emissions through the use of biofuels.

Vegetable oils, animal fats and waste oils ... The flexibility of the Ecofining™ process used at Eni’s Biorefinery in Venice makes it possible to treat a range of loads, however, each has different characteristics that need to be taken into account for process optimisation.
