Advanced Motor Fuels in Italy

Introduction

In 2014, the consumption of primary energy in Italy was around 166 million metrics tons or megatons of petroleum equivalent (Mtpe). As in previous years, oil remained the main energy source, representing 34.5% of consumption. Natural gas followed closely at 30.6%, and the percentage for renewable sources was 20.9% of consumption (Figure 1).

In terms of passenger cars, the top categories were those that ran on gasoline (50.96%), followed by diesel fuel (41.10%). A significant percentage of vehicles also ran on natural gas (2.25%) and LPG (5.51%) (Figure 6).

In addition, diesel-fuelled vehicles could employ up to 7.0% of biodiesel, and gasoline-fuelled vehicles could employ gasoline containing oxygenated biofuels in which the oxygen content could amount to 3.7%.

Policies and Legislation

In both the long- and very-long term (until 2030–2050), Italy will subscribe to the spirit of the European Roadmap 2050 for a low-carbon economy. It aims to reduce emissions by up to 80%. In recent decades, however, it has been difficult to predict developments in technology and to predict vehicle and fuel markets, especially over the long term. Italy therefore intends to adopt a flexible and efficient long-term strategy for pursuing its key low-carbon policy. It will focus on and exploit (especially through research and technological developments) any pursuits that could result in significant positive changes. Examples would be more rapid cost reductions in renewable and storage technologies, use of biofuels, and the capture and storage of carbon dioxide (CO2).

Italian Law has adopted two European directives: Renewable Energy Directive (RED, 2009/28/EC) and Fuel Quality Directive (FQD, 2009/30/EC). Under Italian Law 2009/99 (July 23, 2009) and in accordance with European Specification EN590:2009, the Italian Government has given permission for diesel fuel to contain biodiesel fuel (fatty acid methyl ester or FAME) in a percentage of up to 7%, as in other European Countries. Italian Decree 2011-28 acknowledges all European directives that promote the use of fuels or any other renewable sources. Italy grants energy incentives, like double-counting for using second-generation renewable sources (like those derived from wood cellulose or plant and animal residues). Italian Decree 2012-83 of June 22, 2012, established a limit of 20% for double-counting assigned to second-generation renewable sources.

Moreover, Italian municipalities have implemented important local measures that affect transportation. In order to improve air quality, reduce emissions of particulate matter with a mean diameter of 10 µm or less (PM10), “smooth out” traffic on the road system, and lower noise in the cities, they have introduced measures to limit traffics in urban areas.

Implementation: Use of Advanced Motor Fuels

Biodiesel is the primary source for renewable advanced motor fuel in Italy. From 2009 until the present, biodiesel has been blended with up to 7 vol% diesel fuel. The renewable fuel currently used in gasoline is bio-ethyl tertiary-butyl ether (ETBE), derived from bioethanol. In 2014, the amount of bio-ETBE used in gasoline was 11 kilotons (kt), and the amount used in bio-ethanol was 1.5 kt.

At the end of 2013, there were 996 natural gas stations in the country, as well as a fleet of more than 700,000 passenger cars that use natural gas. The network was located mostly in northern Italy; central and southern Italy were not homogenously represented. In the region of Sardinia Island, there were no natural gas service stations at all. At the end of 2013, the LPG filling station network consisted of 3,250 stations, and there was a fleet of more than 1.9 million LPG-fuelled passenger cars. Figure 7 shows percentages of motor fuels used in 2014.

In 2012, the Italian oil and gas company Eni launched the Green Refinery project, which led to the conversion of the Venice Refinery into a biorefinery that produces innovative and high-quality biofuels. The project is the first in the world designed to convert a conventional refinery into a biorefinery by using the UOP/Eni Ecofining™ technology developed and patented by Eni in collaboration with UOP, a Honeywell company.

The Green Refinery project started with an initial conversion of the existing facilities of the Venice refinery that was started in the second quarter of 2013 and completed by the end of 2013. Biofuel production started in the second quarter of 2014 and has grown progressively as new facilities have begun operating.

At the new green plant site in Venice, industrial operations will be maintained in an economically sustainable manner over the long term, with a low environmental impact. Another activity associated with the Green Refinery project will be the construction of a new logistics center at the Venice plant site.

The Green Refinery project is based on distinctive environmental technologies that are highly compatible with Eni’s continued commitment to research and innovation.

In 2006, Chemtex-M&G began research and development (R&D) activities designed to demonstrate the technological and environmental sustainability of second-generation bioethanol production from lignocellulosic feedstock (PROESA™ technology). Specifically, Chemtex-M&G conducted research on cellulosic crop optimization and agronomics; designed, engineered, developed, and tested (at both laboratory and pilot scales) proprietary technology and components for key aspects of the biomass-to-fuel conversion process; and partnered with leading technology providers to obtain the key biological process components. The world’s largest cellulosic ethanol plant — in Crescentino, Vercelli Province, Italy — began production in 2012. The M&G PROESA™ process technology is extremely economical in converting nonfood biomass to sugars for the production of bioethanol. On October 9, 2013, the new technology was inaugurated at the plant in the presence of the Minister of Economic Development, and other local authorities

With regard to the optimization of the fossil fuel refining process, in 2013, Eni completed construction of the first plant for the total conversion of fossil fuel crudes at the Sannazzaro Refinery. The conversion process is based on its proprietary Eni Slurry Technology (EST). Startup was completed on October 14, 2013. This new hydroconversion process, which can completely convert unconventional oil, heavy crude, and tar sands into high-quality, high-performance fuels, is based on slurry technology that uses a special catalyst and self-starting hydrogen from natural gas. EST is the first invention in the history of scientific discoveries related to the oil sector that came out of Italy, and it came 40 years after the last oil manufacturing process was invented. Unlike traditional oil processes, EST can produce gasoline and gasoil without generating coke or fuel oil, for which the market is constantly declining.

Outlook

Italy has confirmed the 2020 target of 10% for biofuels. At the same time, the country intends to play an active part in reviewing the European Directive, with a view to promoting second- and third-generation biofuels. The review should leave open the possibility for a European assessment on whether to postpone the target in case more time is needed to adequately develop these technologies.

In the short term, the Italian Government has already adopted a number of “tactical” measures to steer the transport sector toward second-generation biofuel production (where Italy has reached levels of excellence). These measures are also designed to foster the development of the domestic and European Union (EU) system throughout the production sector.

In the transport sector, biofuel development is the subject of a wide-ranging international debate, in view of doubts regarding the real sustainability of “traditional” biofuels. The key decision will be whether to transition to second- and third-generation biofuels. For now, however, these biofuels are not able to completely replace traditional sources.

It will also be important to carefully evaluate the prospects for developing the domestic production of bio‑methane for transport use.

Italian Decree, G.U. No. 250, October 27, 2014, defined the yearly minimum increases in the percentage of energy to be derived from biocomponents from 2015 to 2022 as follows:

  • From January 1 to December 31, 2015: 5% biocomponents
  • From January 1 to December 31, 2016: 5.5% biocomponents
  • From January 1 to December 31, 2017: 6.5% biocomponents
  • From January 1 to December 31, 2018: 7.5% of biofuels, of which at least 1.2% is advanced biofuels
  • From January 1 to December 31, 2019: 9% of biofuels, of which at least 1.2% is advanced biofuels
  • From January 1 to December 31, 2020: 10% of biofuels, of which at least 1.6% is advanced biofuels
  • From January 1 to December 31, 2021: 10% of biofuels, of which at least 1.6% is advanced biofuels
  • From January 1 to December 31, 2022: 10% of biofuels, of which at least 2% is advanced biofuels

In 2014, the minimum percentage of energy to be derived from bio-components was 5%.

Algae, straw, crude glycerine, bagasse, shells, and other cellulosic material were considered advanced biofuels.
