The purpose of both natural gas and propane is to reduce emissions, says Tucker Perkins, chief executive of the Propane Education and Research Council, in an interview. The natural-gas infrastructure is more extensive, albeit more expensive — and used more for garbage trucks, he says. Propane, though, has more energy density and it used more for shuttle buses. "Natural gas and propane have shared characteristics and each is a much cleaner fuel than diesel or gas, " he explains. "To use natural gas, you have to be close to the natural gas main and it requires a good electrical system to move it. "Propane moves as an energy-dense fluid and it does not take a lot of energy to get it from the tank to the vehicle, " he continues. "The infrastructure is cheaper and it is easier to adopt" — meaning that it will play a bigger role in the transport sector. While electric vehicles have the inside track right now, other alternatively-fueled cars and trucks are close behind. And natural-gas vehicle makers think they have a good shot to make more inroads among heavy-duty trucks and transit buses.

Globally, though, natural gas has a more expansive role in the passenger car market. And with the change in presidents coming up on January 20, 2021, the Natural Gas Vehicles for America says that the time is ripe to bring its cause to the fore: the goal is to reduce the level of tailpipe emissions in an immediate and cost-effective manner. To this end, the association says that natural gas-powered trucks are now on the road and that they are producing positive environmental results. "Anytime there is a change in presidential administrations or either chamber of Congress, it is a huge opportunity to inform policymakers that there are economic ways to improve energy efficiency, air quality, and climate change, " says Dan Gage, president of the Natural Gas Vehicles for America. "A Biden administration will take on this challenge and look at how it can be achieved. Natural-gas vehicles can be a positive change today. They are a cheaper alternative with a better emissions reduction outcome.
One reason is the fact that car manufacturers do not create LNG personal cars. LNG is cost-effective as long as the car is heavily used, because the evaporation rate of the gas is quite high. Personal use cars do not operate for a long enough time to compensate the evaporation losses. That is why LNG is more appropriate for large vehicles that travel long distances. The benefits of using LNG cars Natural gas vehicles are more environmentally friendly than other types of cars because they have low greenhouse gas emissions. LNG is also very safe, because it is non-toxic, hardly flammable and non-explosive. Another great benefit of liquefied natural gas vehicles is the fuel's low cost. Compared to other diesel fuels, LNG can be produced at a low cost, thus being more affordable. Most LNG used to power vehicles is produced domestically, in the US. LNG has advantages over other types of green solutions for vehicles, like CNG (compressed natural gas), also. Unlike CNG, liquefied natural gas has a high storage density.
The induction of these 18 vehicles is seen as a beginning for change. In keeping with the Clean India campaign, the Gas Authority of India Limited (GAIL) handed over 18 CNG vehicles to the BBMP on Thursday. Murugesan, executive director, Gail India (South Zone), and chief general manager Vivek Wathodkar handed over the vehicles to BBMP administrator Gaurav Gupta and commissioner N Manjunatha Prasad. The 18 vehicles, whose total cost is estimated at Rs 1 crore, can be powered by either CNG or petrol. However, considering the eco-friendly and cost-effective aspect of CNG, the Palike would do well to avoid petrol. Gail has already set up CNG distribution plants in four places. Prasad said the responsibility of dry waste collection has been given to self-help groups, apart from individuals who are engaged in the profession for their livelihood. Dry waste is collected from homes twice a week. The vehicles will help about 7, 500 people engaged in this profession. Till now, the BBMP did not have vehicles to collect dry waste.
It also results in 25% less CO2 than using petroleum. "Everything comes down to what we put into the air. Carbon is where we can get it right or wrong, " adds Carlton Rose, president of the global fleet at UPS. "UPS wants to be part of the solution. And we should be. " Almost daily, he notes, 6% of everything manufactured in this country and 3% of everything produced in the world moves through the UPS network. To be clear, liquefied natural gas, or LNG, is best used with heavy-duty trucks while compressed natural gas, or CNG, is used to power passenger vehicles and corporate fleets. About 20% of public transit buses in this country now run on CNG, and trucks hold potential for greater LNG use. As for UPS, it has CNG vehicles in at least 16 states. It says that it has invested $750 million into alternatively-fueled vehicles and advanced technology vehicles since 2009. But it is also eying all-electric trucks. Natural gas has a mixture of gases that contains propane, which is also used in the transportation sector.
With that, it is to note that all the equipments installed in the car are new. The CNG Tank is Hydro tested for any leakage. Installation of CNG Installing an aftermarket CNG kit is a typical task. It should be done by professionals or under their guidance. The components of successfully retrofitting a CNG kit are. Pressure Regulator Gas/Air Mixer CNG filling valve High-pressure Line CNG tank and valves Petrol/CNG Selector switch Manometer Heating System Emulator CNG Aftercare After the installation, the work doesn't end there. There are specific guidelines for maintaining a vehicle running on CNG. The grade of engine oil for CNG vehicles is different from other counterparts. The vehicle engine is more prone to wear as there is no fluid inside the engine sot frequent engine checkup are necessary for increasing the life of the engine. Running a car on CNG will definitely hamper the performance of the vehicle in a negative way. So one has to be patient while driving one. Air Conditioner of the vehicle takes the drive from the engine which adds more load to it.

It's not just big oil Natural gas utility Integrys Energy Group (NYSE: TEG) is also getting in on the action, through its subsidiary Trillium CNG, which is betting heavily on CNG being the dominant fuel of choice for both the short-haul and long-haul trucking market. The company touts its "fast-fill' systems, which when combined with newer tank technology, significantly enhances the biggest limitation for CNG and trucking -- the very slow speed of refilling a big CNG tank. While the technology has certainly improved for both tank materials and compressor capabilities, CNG will continue to be limited in many areas by the lack of underlying natural gas infrastructure to connect with stations. Clean Energy Fuels ( NASDAQ:CLNE), on the other hand, is the largest supplier of both CNG and LNG to the transportation market already, and is investing heavily in expanding access to both forms of natural gas. Clean Energy already operates more than 400 stations, both public and private, with the vast majority to-date CNG.
). Subsidies to manufacturers, tax credits and cash rebates to customers, and developing CNG fueling station infrastructure are some ideas that could work but this will not happen since it is not a priority at all – America has much bigger fish to fry and some people may even argue is this even a small fish to fry? It would be nice to see America supplying natural gas to Europe and Asia on a much larger scale though. Qatar and Russia – massive natural gas producers – are not America's friends.
Convenience – The worst drawback of CNG is the reduced boot space to accommodate the huge CNG cylinder. CNG as a fuel is not available everywhere. Installation may lead to a change in the vehicle dynamics of the vehicle. Safety- Considering the fact that CNG is safe but not as safe as petrol. Being a gas it is more prone to leakage and catching fire. Green fuel| Guide CNG vs Petrol vs Diesel vs Electric vehicle A person in the current word going out to buy a car has 4 powertrain options (i. e CNG, petrol, diesel and an EV) and buying a vehicle is one of the most crucial decisions of one's life. The first and foremost reason affecting the car buying decision is the kilometers running per day of the car maintenance cost is also a big factor. This is where the Diesel vehicles take a step back. Having high maintenance and the introduction of BS6 has made diesel vehicles even more expensive. For petrol and CNG its kind of mixed bag. A vehicle running on petrol has a low overall buying cost and low maintenance.
Exhaust system: The exhaust system channels the exhaust gases from the engine out through the tailpipe. A three-way catalyst is designed to reduce engine-out emissions within the exhaust system. Fuel filler: A nozzle from a fuel dispenser attaches to the receptacle on the vehicle to fill the tank. Fuel injection system: This system introduces fuel into the engine's combustion chambers for ignition. Fuel line: A metal tube or flexible hose (or a combination of these) transfers fuel from the tank to the engine's fuel injection system. Fuel tank (compressed natural gas): Stores compressed natural gas on board the vehicle until it's needed by the engine. High pressure regulator: Reduces and regulates the pressure of the fuel exiting the tank, lowering it to an acceptable level required by the engine 's fuel injection system. Internal combustion engine (spark-ignited): In this configuration, fuel is injected into either the intake manifold or the combustion chamber, where it is combined with air, and the air/fuel mixture is ignited by the spark from a spark plug.
