Mr. Sulser, what advice does Iveco give to entrepreneurs currently affected by high natural gas prices? In what way can the manufacturer provide support here?

Christian Sulser: Many companies have long-term supply contracts with gas station operators, providing a certain degree of supply and price security. This means they do not have to pay the current price at the pump. Through IVECO Capital, we offer our LNG customers in Germany the option, in hardship cases, to reduce their rental-purchase, leasing, or loan installments.

Additionally, we are in constant contact with politicians, associations, and gas station operators to clarify that today's fossil LNG, which already has sustainability effects, and future green Bio-LNG make a decisive contribution to the decarbonization of road freight transport and thus must receive the appropriate attention from politicians.

Why are there such enormous jumps in the price of fossil LNG at the pump?

The price models for fossil LNG generally refer to an evaluation period of three to four weeks. They are based on average spot market prices (TTF – Title Transfer Facility). The LNG price per kilogram at the pump consists of components such as TTF (spot market price), Gamma price (service fee for gas station operators), energy tax, and CO2 tax. The spot market price is thus the main price driver here.

With increasing availability of biomethane, a product independent of the spot market price will be available in the future. The Bio-LNG price per kilogram at the pump will consist of local production costs, Gamma price (service fee for gas station operators), and energy tax. Minus a quota share for the marketing of the clean gas. The CO2 tax will be completely eliminated.

How is the security of LNG supply maintained in case of absent Russian natural gas?

Fossil LNG is an imported product delivered by sea to various LNG terminals in Europe. This LNG can be transported to the gas station in liquid form using appropriate tank trailers, or it is regasified and fed into the natural gas network. Pipeline natural gas, as it comes from Russia to us, is not used in Germany for the production of LNG.

What is the current situation regarding the demand for natural gas models? Does the production of corresponding trucks proceed unimpeded? Have orders already been canceled or converted to diesel trucks?

This is a unique, unprecedented situation. We strongly believe that the level of gas prices will realign below diesel prices in the coming months. As mentioned earlier, with increasing availability of biomethane, a product independent of fossil gas and its associated pricing structure will be available in the future. This will not only save costs but also drastically reduce CO2 consumption.

We continue to see a high share of gas vehicles in total sales of heavy commercial vehicles. There is some uncertainty regarding current delivery times due to raw material shortages and the semiconductor situation. Customers are questioning how long they can benefit from toll exemptions when the vehicle is delivered. The LNG price may be quite different by then.

Currently, LNG vehicles are unlikely to be economically viable – what is your medium- and long-term forecast for the competitiveness of this type of drive?

Gas propulsion with its potential for biomethane is not just a bridge. Bio-LNG is currently the only scalable regenerative fuel. Our customers can already drive almost CO2-neutral with it today and achieve ranges of up to 1,600 kilometers and more with the IVECO S-WAY LNG. From an ecological point of view, we cannot afford to wait until BEV and FCEV are available in sufficient quantities and, above all, until the necessary infrastructure is available.

In the future, we see the market share of heavy commercial vehicles with gas propulsion at ten to fifteen percent by 2030. A large part of the remaining market can be covered by BEV and FCEV, although diesel will remain with us to some extent. However, in this transition phase, it will certainly become increasingly difficult for it in the future, especially with appropriate CO2 taxation and the possible gradual withdrawal of the diesel privilege.

In the future, will there be enough Bio-LNG and what is it made from?

According to the European Commission, there is sufficient so-called biomethane feedstock available. In a press release dated March 8, 2022, it states that 350 TWh by 2030, which is approximately 35 billion m³, will be available. As part of the 35 billion m³ goal, the Commission aims to double the amount of biomethane in the EU already in 2022. Raw materials available for biomethane production include raw and residual materials such as manure, food waste, industrial wastewater, and agricultural residues such as straw.

The production of Bio-LNG is far less complex than the production of green alternatives for diesel fuels. Bio-LNG is produced by liquefying biomethane and can be fully obtained as a so-called "advanced biofuel" from the aforementioned residues.

A second method is the production of synthetic gas using Power-to-Gas (electricity-to-gas) technology. Excess green electricity is used to split water into oxygen and hydrogen via electrolysis. The hydrogen can be converted into synthetic methane through methanation and then into green, electricity-based LNG via a liquefaction plant.

In Germany, several gas station operators have already announced plans to build Bio-LNG liquefaction plants in the near future to supply their and our customers nationwide with Bio-LNG. This will ensure that there is enough Bio-LNG available to not only meet the demand in the short term but also to explore additional potentials.

How clean are trucks running on Bio-LNG?

Even fossil LNG is a clean and future-proof alternative to diesel. Emission-free road freight transport is already a reality today, as with Bio-LNG we are already on the right track. Bio-LNG is a 100 percent renewable energy source. The advanced technology contributes to an improvement in air and life quality with significantly lower particulate emissions and a substantial reduction in noise. Bio-LNG is considered the most environmentally friendly fuel for combustion engines and reduces CO2 emissions by up to 95 percent in a well-to-wheel analysis.

How many LNG filling stations are currently available in Germany and at how many can Bio-LNG already be refueled?

As of today, there are around 120 public LNG filling stations in Germany. The share of Bio-LNG at these stations is still relatively small. However, many filling station operators are currently starting initial test projects. Further information is gladly provided by the station operators.

Keyword circular economy, is that also an option with LNG?

Sure, why not, if the prerequisites are there. A well-known German organic supermarket chain is currently setting an example. It is consciously investing in IVECO S-WAY LNG vehicles. The required Bio-LNG is produced by the supermarket chain itself. Its own farm with sufficient manure, a biogas plant, and a methane liquefier makes a circular economy with CO2-neutral market supply possible.

Can IVECO trucks simply run on Bio-LNG?

The Cursor-9 and Cursor-13 gas engines used in the IVECO S-Way NP, with Euro VI Step E emission standards, can be fully operated with certified Bio-LNG. Technical conversions or special adjustments are not necessary, and the warranty conditions and same maintenance intervals as when using fossil LNG remain unchanged. Additionally, electrical-based fuels can also be used in these vehicles in the future.

The customer has the absolute freedom of choice regarding the origin of the fuel and can decide with each refueling whether to use green fuel with higher CO2 savings or continue with fossil fuel—which also contributes to a CO2 reduction compared to diesel vehicles—each at attractive costs and without the need for technical adjustments. Additionally, CO2 savings become an additional "currency" for haulers and freight forwarders. In short: green and with very good TCO!

Which LNG vehicle is currently IVECO's bestseller?

The clear bestseller is the IVECO S-WAY LNG 4x2 standard tractor unit with a Cursor 13 gas Otomotor with 460 HP and Euro VI Step E emission standard. The two 540-liter tanks can hold at least 390 kilograms of LNG or Bio-LNG. This allows long-distance ranges of up to 1,600 kilometers depending on the application and route profile.

However, we are continuously expanding our portfolio of gas-powered environmentally friendly commercial vehicles, and now many S-WAY and X-WAY chassis with various configurations and cab models are available as LNG or CNG variants.

How long is the toll exemption for LNG trucks in Germany and what happens afterward?

The toll exemption for LNG and CNG trucks remains valid until the end of 2023. It appears that these vehicles will continue to benefit from a toll advantage compared to diesel beyond that.

Finally, a question about engine technology. Currently, there are vehicles on the market with High Pressure Direct Injection (HPDI) and Spark Ignition (SI). Which system does IVECO use and why?

IVECO relies on the SI system and thus on the Otto principle for its gas Otomotoren. The advantages compared to the HPDI system, used by only one market competitor, are clear: Instead of having to refuel with LNG, diesel, and AdBlue at the filling station, an IVECO SI engine only requires LNG. Additionally, the gas Otomotor is up to 50 percent quieter compared to diesel and is also perfect for use in traffic-calmed zones and for night deliveries.

Another advantage of IVECO's monovalent gas vehicles is the free travel in environmental zones, as they are exempt from the nighttime driving ban on the Inntal highway, for instance. Gas vehicles with bivalent HPDI drive must, of course, adhere to the driving ban. IVECO uses LNG tanks with Economizer, which allows the use of gas pressure. A stable working pressure of 9.5 bar and a stable internal tank temperature often avoid the need to vent the tank before refueling. In comparison, HPDI requires an LNG tank with a cryogenic pump. The LNG gas phase cannot be used by the engine, and venting is generally required before refueling.

But the most important advantage for a long-distance truck is likely the range. Our IVECO S-WAY NP is equipped with two 540-liter tanks, which can hold at least 390 kilograms of LNG or Bio-LNG. This allows for a range of up to 1,600 kilometers, as confirmed by many haulers. Since an HPDI system, as mentioned earlier, requires diesel, AdBlue, and LNG along with the correspondingly complex exhaust after-treatment of a diesel engine, and because tank mounting space on the truck is limited, the range with this technology is reportedly only about half as large, according to drivers at the filling station. IVECO has been investing in alternative drives and the SI system for more than 20 years. In 2020, we were market leaders in Germany with over 70 percent market share in gas-powered tractor units for a reason.
