compressed natural gas

Compressed natural gas is a fossil fuel alternative to petroleum and coal, consisting mainly of methane and used as a fuel for vehicles, power generation, and industrial processes. It is considered a cleaner-burning fuel than diesel fuel and gasoline, producing fewer greenhouse gas emissions and air pollution when burned, as noted by the United States Environmental Protection Agency and the International Energy Agency. The use of compressed natural gas is supported by organizations such as the National Petroleum Council and the American Gas Association, which promote its benefits, including reduced carbon dioxide emissions and improved air quality, as seen in cities like Los Angeles and New York City. Compressed natural gas is also used in combined heat and power systems, which are promoted by the European Union and the United Nations.

Introduction

Compressed natural gas has been used as a fuel for vehicles since the 1970s, with countries like Argentina and Brazil being early adopters, as reported by the International Association of Natural Gas Vehicles. The use of compressed natural gas has grown significantly in recent years, with many countries, including China, India, and the United States, promoting its use as a cleaner alternative to traditional fuels, as noted by the World Health Organization and the National Institute of Environmental Health Sciences. Companies like General Motors and Ford Motor Company have developed vehicles that run on compressed natural gas, which are used by UPS and FedEx for their delivery fleets, reducing their carbon footprint and improving air quality in cities like Chicago and Houston. The European Commission and the Asian Development Bank have also supported the development of compressed natural gas infrastructure, including pipelines and fueling stations, in countries like Poland and Thailand.

Composition and Properties

Compressed natural gas is composed primarily of methane, with small amounts of other hydrocarbons like ethane and propane, as well as nitrogen and carbon dioxide, as analyzed by the National Institute of Standards and Technology and the American Society for Testing and Materials. The physical properties of compressed natural gas, such as its density and viscosity, are similar to those of liquefied petroleum gas, as noted by the Society of Automotive Engineers and the American Petroleum Institute. The calorific value of compressed natural gas is approximately 55 megajoules per kilogram, which is higher than that of coal and wood, as reported by the World Bank and the International Energy Agency. The ignition temperature of compressed natural gas is around 600 Celsius, which is lower than that of diesel fuel and gasoline, as studied by the National Aeronautics and Space Administration and the European Space Agency.

Production and Processing

Compressed natural gas is produced from natural gas wells, which are operated by companies like ExxonMobil and Royal Dutch Shell, as reported by the United States Energy Information Administration and the International Energy Agency. The natural gas is processed to remove impurities like water and hydrogen sulfide, as described by the American Petroleum Institute and the Gas Processors Association. The processed natural gas is then compressed to a pressure of around 200-250 bar, which is higher than the pressure used for liquefied natural gas, as noted by the Society of Automotive Engineers and the American Society of Mechanical Engineers. The compressed natural gas is stored in cylinders or tanks, which are designed to withstand the high pressures and are used by companies like Praxair and Air Liquide, as reported by the Compressed Gas Association and the European Industrial Gases Association.

Applications and Uses

Compressed natural gas is used as a fuel for vehicles, including buses, trucks, and cars, which are manufactured by companies like Toyota and Volkswagen, as reported by the International Council on Clean Transportation and the European Automobile Manufacturers Association. It is also used for power generation, particularly in combined heat and power systems, which are promoted by the European Union and the United Nations, as noted by the World Energy Council and the International Renewable Energy Agency. Compressed natural gas is used in industrial processes, such as metalworking and chemical processing, as described by the American Iron and Steel Institute and the Chemical Industry Association, and is supported by organizations like the National Association of Manufacturers and the International Chamber of Commerce. Additionally, compressed natural gas is used as a fuel for cooking and heating in homes and commercial buildings, as reported by the United States Department of Energy and the National Fire Protection Association.

Safety and Environmental Considerations

Compressed natural gas is considered a safe fuel when handled properly, as noted by the National Fire Protection Association and the Occupational Safety and Health Administration, which have established guidelines for its handling and use, as reported by the Compressed Gas Association and the European Industrial Gases Association. However, it can be hazardous if it leaks or is not stored properly, as warned by the United States Environmental Protection Agency and the European Chemicals Agency, which have established regulations for its storage and transportation, as noted by the Pipeline and Hazardous Materials Safety Administration and the European Union's Directorate-General for Energy. Compressed natural gas is a cleaner-burning fuel than coal and oil, producing fewer greenhouse gas emissions and air pollution when burned, as reported by the Intergovernmental Panel on Climate Change and the World Health Organization, which have promoted its use as a cleaner alternative to traditional fuels, as supported by organizations like the National Petroleum Council and the American Gas Association.

Infrastructure and Storage

The infrastructure for compressed natural gas includes pipelines, fueling stations, and storage facilities, which are operated by companies like Kinder Morgan and Enterprise Products Partners, as reported by the Federal Energy Regulatory Commission and the European Union's Directorate-General for Energy. The storage facilities for compressed natural gas are designed to withstand the high pressures and are typically located near natural gas wells or pipelines, as described by the American Petroleum Institute and the Gas Processors Association, which have established guidelines for their design and operation, as noted by the Society of Automotive Engineers and the American Society of Mechanical Engineers. The fueling stations for compressed natural gas are designed to dispense the fuel at high pressures and are typically located near highways and urban areas, as reported by the International Association of Natural Gas Vehicles and the National Association of State Energy Officials, which have promoted their development, as supported by organizations like the United States Department of Energy and the European Commission.
