Volkswagen has completely overhauled its natural gas models and is equipping its Polo and Golf TGI with a third natural gas tank. This allows the Polo TGI to now travel up to 60 kilometers further in pure CNG mode than its predecessor. The gain in range in the Golf TGI is up to 80 kilometers. In the Golf, a new 1.5 liter TGI four-cylinder engine with 96 kW/130 PS ensures that none of the driving pleasure is lost. The nw natural gas-powered TGI models are available to order now

Volkswagen has equipped its natural gas models of the Polo TGI and Golf TGI with a third natural gas tank made of specially coated, high-strength steel. The Golf’s tank has a volume of 23 liters and increases the total CNG tank volume to 115 liters, or 17.3 kg respectively, which offers a range of up to 422 kilometers in WLTP.

On the Polo with 1.0 three-cylinder engine (66 kW / 90 PS) the additional tank carries 16.5 litres and extends the natural gas storage to 91.5 liters in total, or 13.8 kg respectively, meaning that the Polo can travel up to 368 kilometers on CNG in WLTP. As a back-up, both models come with a petrol tank – albeit a much smaller version.

For improved driving dynamics and efficiency, the Golf TGI’s new 1.5 liter four-cylinder engine is powerful, efficiency and environmentally friendly. Proof of this comes from its fuel consumption of just 3.6 kg – 3.5 kg natural gas over 100 kilometers, and CO2 emissions of just 98–95 g/km. This engine uses the innovative TGI Miller combustion process with a high compression ratio of 12.5:1, to increase efficiency and decrease CO2 emissions. A turbocharger with variable turbine geometry increases the boost pressure, adding more air into the cylinders. This allows the 1.5-litre TGI engine to accelerate powerfully at any time from low speeds.

Renewable gas producers will be able to bring their fuel to the market more economically thanks to the new leasing service developed by Grupo Industrial Calvera, a Spanish company specializing in gas transportation. This company, which has already signed two leases, one with an international industrial gas and hydrogen company and the other with a major Spanish gas supplier, now plans to extend the service to all of Europe.
With this formula, described as “an authentic industry first in the sector”, Calvera offers the possibility of renting its full range of gas transport options, including trailers and mobile refueling units to customers such as suppliers of biomethane, energy services companies and energy facilities. The company indicates that this service will significantly improve the profitability of many biogas producers and renewable hydrogen projects, as well as it will attract companies specialized in gas transportation.
To announce this new service, Calvera has received more than 20 companies -including Gasunie, Honda, Total and Engie- at its Épila plant, near Zaragoza, where they showcased their latest innovations and products, such as mobile gas pipelines for hydrogen and biomethane as well as equipment available for leasing.
Rafael Calvera, General Director of Calvera, said about the service: “Taking the gas to the end user in the most profitable way can be a challenge for the producers of hydrogen, biomethane and CNG. We think that this leasing service makes the supply and distribution of “green” gas more efficient from the economic point of view, simplifying the business model in general. In any new strategy it will reduce the initial capital expenditures and will help the overall financing of the project.”
With this service the entire Calvera range is available, including its mobile refueling equipment and the light modules that can be loaded and unloaded from the tanker trucks with a hydraulic boom crane with hook. All leased vehicles will receive full maintenance by the Calvera team of specialists.

Xebec announced the operation of its first ever Italian biogas upgrading plant in Modena. Based on Xebec’s innovative Pressure Swing Adsorption (PSA) product line, the plant is successfully producing pure biomethane, also known as renewable natural gas, and injecting it into the local gas grid of AS RETIGAS.

Environmental service provider AIMAG had been collecting municipal waste, specifically source-separated organics, to produce biogas through an anaerobic digester (AD). The biogas was purified and used as renewable energy for a combined heat and power (CHP) unit.

AIMAG hired environmental engineering and construction firm Atzwanger AG-SpA to help them maximize their biogas opportunity. Atzwanger chose Xebec as its upgrading supplier after extensive evaluation of various technologies. Xebec’s innovative PSA technology was selected as the most reliable, cost effective and simple solution in this specific setting.

“This brand new dry-digestion-plant of organic waste is one of the first in the country to feed biomethane into a public grid thanks to the vision and determination of our client AIMAG, and one of the fastest ever built thanks to our key partners Xebec and Strabag,” said Dr. C. Atzwanger, Managing Director, Atzwanger AG-SpA.

Dr. Francesco Massari, General Manager, Xebec Europe, also commented: “We’re delighted to have this first Xebec upgrading system operating in Modena, proving our system’s performance and reliability in Italy. Xebec is already a market leader in France with over 20 PSA systems delivering consistent, quality biomethane to customers. Italy is strategically becoming the second key market for Xebec in Europe.”

Snam, through its subsidiary Snam4Mobility, has acquired 100% of Enersi Sicilia Srl, a company that owns the authorization for the development of a plant to convert biomethane from urban solid waste in the province of Caltanissetta, Sicily. Snam4Mobility is the company through which Snam is developing refueling infrastructure for CNG and LNG vehicles. 
This acquisition, for approximately EUR 2 million, will allow Snam to build its first biomethane plant that will be able to manage 36,000 tons per year of urban waste, providing neighbouring municipalities with a totally renewable solution to the problem of waste disposal.
The plant will be built by leveraging the managerial and technical expertise of the subsidiary IES Biogas, which will oversee its development and construction. 
Snam4Mobility is the company through which Snam is developing refueling infrastructure for compressed natural gas (CNG) and liquefied natural gas (LNG) vehicles. The growing interest in the sustainable methane and biomethane mobility market demonstrates the great potential of alternative uses of gas.
Biomethane is a renewable energy source derived from a process of purification of biogas, which is obtained from the exploitation of products and by-products of the agricultural and agro-industrial chain and from the organic part of urban waste. Biomethane can be fed into the natural gas transport infrastructure.
A study carried out by Ecofys for the European Gas for Climate consortium (which includes Snam and eight other companies and associations) estimated that the production and use of biomethane and other renewable gases in existing infrastructure would enable Europe to meet the climate targets of the Paris Agreement, saving around 140 billion euro per year by 2050.
