The FAA says it will allow propane tanks to be installed in an indoor flight zone in the U.S. and the world’s most populated cities, as a way to improve air quality.
The new rules were issued Wednesday by the Federal Aviation Administration (FAA), which regulates propane tankers.
Propane tanks can be installed indoors or outdoors, and can be used to generate heat and power.
The FAA says the rule allows for outdoor tankers to be equipped with a battery-powered propane generator, which will reduce the amount of emissions produced when the tanks are being used indoors.
Propanes are used in refrigeration, heating, cooking, and transportation.
The FAA has also made a request for public comment on how the rule will impact propane use in aircraft, which are used more often than other fuels for heating and cooling.
Propano is used to heat food, fuel, and other materials and can help cut the carbon footprint of jet engines.
As a result of the rule, propane, the most commonly used fuel in jet engines, will be allowed to be used in all U. S. cities for the first time in years.
Propane can be generated in any way and can also be stored for long periods of time indoors, but the FAA says that the indoor requirement requires it to be kept in a container that is airtight and ventilated to allow air to circulate freely.
Propane tanks have long been used to make engines more efficient, and the FAA is aiming to limit emissions of volatile organic compounds (VOCs) that are a major contributing factor to air pollution.
“We want to ensure that all the vehicles on the roads have the proper technology and the right tools to get this right,” FAA Administrator Michael Huerta said in a statement.
The agency is also considering permitting an indoor fuel system in the future.
More than 100 cities and towns have applied for the right to put propane fuel tanks in their airways, and a total of 856 applications have been submitted, according to the FAA.
