Manuel Lage, Dr. Eng. General Manager

Rotterdam, December 2010 1 Advantages of bio natural gas

• Natural gas is an alternative fuel coming from natural wells. It is mainly methane (CH4) • Biogas is also a methane rich gas, produced by the fermentation of the biomass, it is then a renewable fuel. • Methane contents 25% H and 75% C, in weight As a comparison, • Petrol contents 13,5% H and 86,5% C • Diesel oil contents 13,5% H and 86,5% C • LPG contents 17,4% H and 82,6% C

Due to its molecular advantage, regulated exhaust emissions and CO2 are particularly favourable in the engines running on natural gas.

Rotterdam, December 2010 9 The bright future of NGV’s

• The DG MOVE (EU) is preparing a white paper with the title: Report of the European Expert Group on Future Transport Fuels Fuels in which there is a significant support to the NG, following the contributions given by NGVA Europe, the only NGV expert invited to the group.

• The development of NGV’s in the medium and long term future, other than the existing and well established technologies, will be wide and following five additional main lines:

– CNG Hybrid Vehicles – Dual Fuel Technology for heavy duties – Biogas – LNG for trucks and buses – Methane-Hydrogen mixtures

Rotterdam, December 2010 10 CNG Hybrid Urban buses

Castrosua TEMPUS CNG Hybrid. New urban bus presented in FIAA Madrid (November 2010)

The municipality of Madrid has already passed orders for 23 CNG-Hybrid buses: • 13 Castrosua • 10 .

Tata Starbus CNG Hybrid, to be produced in Europe by: Tata Hispano, Zaragoza, Spain.

Rotterdam, December 2010 11 Dual Fuel technology available

• Dual fuel systems have been developed to substitute a major part of diesel for natural gas in heavy duty engines, keeping the Diesel cycle • Retrofit market considered too for EURO 2 and 3 vehicles • Full diesel operation is available, when run out of CNG • The natural gas injection system is electronically controlled with a separate ECU. • Legislation still under development • Dual fuel system is an alternative to dedicated NG engines

Members of NGVA Europe offering Dual Fuel technologies:

Rotterdam, December 2010 12 Biogas production potential

EU is still missing a European legislation for the injection of biomethane in the NG grid. NGVA Europe is working also in the next legislation about the gas quality.

Among different options of biofuels, biomethane presents the highest efficiency per hectare of land. A global European estimation shows a potential of 2.750 TWh (9,9EJ=238Mtoe), made out of 1.500 TWh (5,4 EJ=130Mtoe) coming from crops, plus another 1.250TWh (4,5EJ=1.108Mtoe) coming from other sources: sewage, manure, landfills, etc.

If we choose bioethanol instead of biogas we would loose the potential of the waste, sewages, etc (1.250TWh, 4,5EJ=108Mtoe) and we would also reduce the efficiency of the land by 47%. In other words we would obtain 800TWh (2,9EJ=70Mtoe) instead of 2.750TWh (9,9EJ=238Mtoe).

Rotterdam, December 2010 13 LNG (Liquefied Natural Gas) NG with a high energy density

LNG opens the way for the medium and long distance road transport

Rotterdam, December 2010 14 First in Europe LBG (Liquid Bio Gas) truck

Rolande LNG B.V., a specialist in supplying LNG and LBG for road transport applications, has recently introduced the first truck running on Liquid Bio Gas. Rolande LNG B.V. made this concept to work by converting, in close cooperation with the OEM, an IVECO Stralis CNG into a truck being capable to run on LNG/LBG. Rolande LNG B.V. provided not only the know how but also the special cryogenic tanks and heat exchanger. LBG is made from gas coming out of a landfill. It gives better emission levels than EEV or Euro 5 diesel engines. LBG CO2 emissions (Well to Wheel) are by far the best alternative to any other bio fuel currently available (up to 80% CO2 reduction compared to diesel). The truck is being used to show and promote the many advantages of LBG as fuel: It is cleaner (better than future Euro 6), quieter (5 dba lower noise level than a diesel) and up to 80% CO2 neutral! There is no better and economic alternative today. LBG can save between 2 and 5 €cents per km. The truck can run more than 1.200 km before refuelling.

Rotterdam, December 2010 16 LNG supply to Europe

Rotterdam, December 2010 17 The “LNG Blue Corridors”

The availability of LNG all around the Iberian Peninsula, plus the French port of Fos (Marseille), and the Italian ones of Panigaglia (near Genova) and Revigo (near Trieste) constitutes a fantastic existing infrastructure to cover all the supply needs for road transport around the Mediterranean arch.

Another corridor could also be imagined from Portugal and Spain to the north of France, Belgium, Netherlands, UK, north of Germany and Denmark, once all the LNG terminals, now under construction, will be in service.

Rotterdam, December 2010 18 Methane/Hydrogen mixtures

Methane/Hydrogen mixture (Hythane, Hydrometano) offers a number of significant advantages as a bridge solution for a future hydrogen fuelled transport:

–It can be used in the existing NGV engines and vehicles with minor engine resetting –The inboard fuel storage uses the same type of tanks and fittings, with some specification changes in materials –The H2 content considered (up to 30%) does not alter the autonomy of the vehicles –There is an immediate impact as CO2 emission reduction (- 11%) –The use of compressed H2 in a “large” basis will push ahead the development of the hydrogen production and logistics

Rotterdam, December 2010 19 Conclusions

• Natural gas (methane) is an excellent energy vector, with the lowest Carbon to Hydrogen ratio of all the hydrocarbons. Additionally natural gas is an alternative fuel, having a different origin from the traditional oil derived diesel, petrol and LPG

• Natural gas is used in existing internal combustion engines, with minor additional investments, taking advantage of a well known and mature car & commercial vehicle technology. Dual Fuel technology offers the possibility of conversion for existing engines

• The increasing production of biomethane, both from urban waste and from agricultural stuff is giving natural gas the new and valuable consideration of a renewable fuel

• Natural gas has been used so far as CNG mainly for urban applications. The availability of LNG will spread its use for medium and long distances road transport

• Methane/Hydrogen mixtures, that could be used the existing NGVs will become the bridge to a potential hydrogen fuelled transport

• NG vehicles are today the best and most economic alternative to oil derived fuels, also improving gaseous and acoustic emissions.
