Enhanced Natural Gas Storage to Help Reduce Global Warming

Researchers from KAIST University have designed plastic-based materials that can store natural gas more effectively. These new materials can not only make large-scale, cost-effective, and safe natural gas storage possible, but further hold a strong promise for combating global warming.

Natural gas is a clean energy alternative. It is stored by compression, liquefaction, or adsorption. Among these, adsorbed natural gas (ANG) storage is a more efficient, cheaper, and safer alternative to conventional compressed natural gas (CNG) and liquefied natural gas (LNG) storage approaches that have drawbacks such as low storage efficiency, high costs, and safety concerns. However, developing adsorptive materials that can more fully exploit the advantages of ANG storage has remained a challenging task.

A KAIST research team led by Professor Cafer T. Yavuz from the Graduate School of Energy, Environment, Water, and Sustainability (EEWS), in collaboration with Professor Mert Atilhan’s group from Texas A&M University, synthesised 29 unique porous polymeric structures with inherent flexibility, and tested their methane gas uptake capacity at high pressures. These porous polymers had varying synthetic complexities, porosities, and morphologies, and the researchers subjected each porous polymer to pure methane gas under various conditions to study the ANG performances.

Of these 29 distinct chemical structures, COP-150 was particularly noteworthy as it achieved a high deliverable gravimetric methane working capacity when cycled between 5 and 100 bar at 273 K, which is 98% of the total uptake capacity. This result surpassed the target set by the United States Department of Energy (US DOE). COP-150 is the first ever structure to fulfil both the gravimetric and volumetric requirements of the US DOE for successful vehicular use, and the total cost to produce the COP-150 adsorbent was only 1 USD per kilogram.

COP-150 can be produced using freely available and easily accessible plastic materials, and moreover, its synthesis takes place at room temperature, open to the air, and no previous purification of the chemicals is required. The pressure-triggered flexible structure of COP-150 is also advantageous in terms of the total working capacity of deliverable methane for real applications.

The research team believed that the increased pressure flexes the network structure of COP-150 showing “swelling” behaviour, and suggested that the flexibility provides rapid desorption and thermal management, while the hydrophobicity and the nature of the covalently bonded framework allow these promising materials to tolerate harsh conditions.

This swelling mechanism of expansion-contraction solves two other major issues, the team noted. Firstly, when using adsorbents based on such a mechanism, unsafe pressure spikes that may occur due to temperature swings can be eliminated. In addition, contamination can also be minimized, since the adsorbent remains contracted when no gas is stored.

Professor Yavuz said, “We envision a whole host of new designs and mechanisms to be developed based on our concept. Since natural gas is a much cleaner fuel than coal and petroleum, new developments in this realm will help switching to the use of less polluting fuels.”

Professor Atilhan agreed the most important impact of their research is on the environment. “Using natural gas more than coal and petroleum will significantly reduce greenhouse gas emissions. We believe, one day, we might see vehicles equipped with our materials that are run by a cleaner natural gas fuel,” he added.

Naturgy Inaugurates Its First CNG Station in Cartagena

Naturgy has inaugurated the first public natural gas supply station for vehicles in Cartagena. The plant, which allows the supply of compressed natural gas (CNG), is located on Pedro Sánchez Meca Avenue in Cartagena, in a strategic location close to the port activity.

This new refueling point is added to the one currently held by the energy company in the Murcia neighbourhood of the Era Alta and which supplies compressed natural gas (CNG) to both public fleets and private vehicles. In addition, it is expected that in the coming months a third will be inaugurated in Molina de Segura that will allow refuelling of both light and heavy vehicles by having suppliers in both compressed natural gas (CNG) and liquefied natural gas (LNG) form.

The implementation of this new natural gas supply station is part of the company’s mobility promotion project, which aims to enhance the use of natural gas as a fuel as the best sustainable alternative to fossil fuels derived from petroleum.

This new public natural gas supply station represents a further step for Naturgy in its commitment to move forward in the transition to clean energy transport models that contribute to improving air quality and, therefore, people’s health.

The new map of vehicular natural gas recharging points in Spain will allow to meet the increase in demand in the coming years and strengthen the availability of this fuel in the market, given the increase that vehicles powered by natural gas are experiencing.

Volkswagen Group and Industry Partners Further Expand CNG Mobility

Volkswagen Group and its industry partners from the gas supply, network, and filling station operation showcased their products and services at the 3rd CNG Mobility Days in Berlin (25-26 June 2019), presenting an overview of the current situation and the future of CNG. Volkswagen Group brands will also be exhibiting their latest CNG models in the passenger car, truck and bus segments.

In parallel with the advancing electrification of its fleet, Volkswagen Group and its brands continue to rely on compressed natural gas (CNG) as an alternative drive technology for decarbonising road transport, and the product range has been revised and expanded again with this in mind.

Volkswagen Group currently offers the widest selection of CNG vehicles of any manufacturer, by a substantial margin. At the annual general meeting in mid-May 2019, Herbert Diess, Chairman of the Board of Management of Volkswagen AG, announced that CNG will continue to play an important role for the Group in the future: “We are the global market leader for gas drive systems, and better positioned than our competitors. We also plan to continue further expanding and improving this technology.”

Using CNG as an energy source for automobiles meaningfully contributes to reducing emissions, as well as representing a cost-efficient customer alternative to petrol and diesel. “Volkswagen is committed to the Paris Climate Agreement. CNG has an important role to play in the alternative drive systems strategy that runs alongside the Group’s electrification offensive. It is sufficiently proven, immediately available, efficient and cost-effective. Furthermore, CNG cars are not affected by driving bans in city centres,” explains Stephen Neumann, Volkswagen Group Representative for CNG Mobility. He adds: “Refuelling with biomethane or e-gas results in an even better CO2 balance. Biomethane is obtained from organic residues, while e-gas is produced from excess green electricity (power-to-gas).

Both can easily be fed into the gas network and mixed with any amount of fossil natural gas.” Volkswagen Group brands and their industry partners have been working in this field for some time; Audi has been operating the world’s first industrial power-to-gas plant in Werlte (Emsland) since 2013, for example, with the Audi e-gas produced from wind power being fed into the natural gas grid – making Audi both a participant and a catalyst in the energy revolution. Green energy is made available to vehicle customers, while at the same time the storage of fluctuating eco-power and its research in practice enables the rapid expansion of wind and solar energy, which is also important to the success of e-mobility.

SKODA Presents Natural Gas SCALA G-TEC in Berlin

SKODA has introduced the most eco-friendly variant of its new compact model at the CNG Mobility Days event in Berlin which took place on 24/25 June 2019: the SKODA SCALA G-TEC. This natural gas SCALA completes the engine roster for the new compact model, adding a particularly efficient and eco-friendly variant. The 1.0 G-TEC has a peak output of 66 kW (90 PS), with three CNG tanks enabling a range of around 410 kilometres in natural gas mode, according to preliminary data.

Christian Strube, SKODA Board Member for Technical Development, explains: “Natural gas will play a key role in SKODA’s engine portfolio over the coming years in order to lower CO2 emissions. Our natural-gas engines are becoming more and more popular with our customers because of their low emissions. And anyone driving a SKODA SCALA G-TEC will in future also benefit from comparatively low fuel costs in many countries.”

SKODA is building a range of eco-friendly natural-gas models. The new SKODA SCALA G-TEC joins the OCTAVIA G-TEC as the second natural gas model in the SKODA model range. The new SCALA G-TEC is powered by a three-cylinder turbo with a 1.0-litre displacement and an output of 66 kW (90 PS). Its maximum torque of 160 Nm is transmitted via a 6-speed manual gearbox. The SCALA G-TEC is specifically designed for CNG use and complies with the Euro 6d-TEMP emissions standard. CO2 emissions are reduced by around 25% compared to running on petrol, with considerably lower nitrogen oxide (NOx) emissions as well and no particulates.

The SCALA G-TEC comes with three linked steel CNG tanks accommodating 13.8 kilograms of CNG. This enables the compact model to cover around 410 kilometres in the eco-friendly and efficient natural-gas mode. Should the CNG run out, the SCALA will automatically switch to petrol mode, where a nine-litre tank allows it to cover around 220 additional kilometres. As a result, the SCALA G-TEC remains mobile in regions without natural gas filling stations, with a combined range of around 630 kilometres.

Thanks to the clever way the CNG tanks are integrated in the underbody, the SCALA G-TEC has a luggage capacity of 339 litres – a best-in-class value for natural gas vehicles in this segment.
