Natural gas (NG) has long been considered as a promising alternative to less clean burning fossil fuels, both in the industrialized and developing countries. Consisting primarily of methane, together with ethane and other hydrocarbons, natural gas is the cleanest burning of all fossil fuels, and abundant resources means it doesn’t have to be imported. It can be used in power plants to generate electricity or for home heating, and vehicles can be easily modified to run on natural gas. The only potential problem is efficient storage. Being a gas, NG can take up significant volume when being stored. This poses challenges for use in automobiles, or for transporting in areas where pipelines are unavailable. Increasing storage pressure can reduce volume, but this requires more expensive containment and handling systems.

Energtek, a U.S. company based in New York, believes it has the best answer. The company is a world leader in the development and commercialization of what is called Adsorbed Natural Gas (ANG), the use of microporous materials to increase the efficiency of natural gas storage. Using materials with the correct physical properties allows methane and other NG related molecules to adhere tightly to the materials, resulting in denser storage. ANG effectively reduces the volume and/or pressure required to store a given amount of natural gas.

With ANG, you can store a larger volume of NG in the same container, or you can reduce the pressure required to store the same amount of NG. ANG technology can be adjusted to fit the need. For use with vehicles, required pressures can be reduced, making it easier for people to handle. For storage and delivery, more gas can be captured in a given container at the same pressure. However ANG technology is applied, the result is more efficiency and reduced costs.

Energtek provides proprietary solutions to meet the technical and economical challenges of NG delivery to vehicles worldwide, with a major focus on the 2-3 wheel vehicle market in Asia. In addition, Energtek supplies NG to industrial and commercial consumers, using pipeless NG supply bulk transportation solutions.
