Grilling season is upon us, and the tantalizing aroma of barbecued delights fills the air. For many, the choice between propane and natural gas grills is a crucial one. While propane grills rely on portable tanks, the convenience of a direct natural gas line often appeals to homeowners. But what if you crave the consistency of natural gas without the hassle of permanent plumbing? This raises a vital question: can you actually buy natural gas in tanks for your grill? The answer, while not a simple yes or no, unveils a landscape of options, challenges, and important considerations.
Understanding Natural Gas and Propane Differences
Before diving into the availability of natural gas tanks, it’s essential to grasp the fundamental differences between natural gas and propane. Both are hydrocarbon gases, but their chemical compositions and properties diverge significantly.
Natural gas is primarily methane (CH4) and is lighter than air. It’s typically delivered through underground pipelines directly to homes. Its pressure is lower than propane, requiring different regulator settings on appliances. Propane, on the other hand, is liquefied petroleum gas (LPG), consisting mainly of propane (C3H8) and butane (C4H10). It’s heavier than air and stored under pressure as a liquid in portable tanks.
The key takeaway is that natural gas and propane appliances are not interchangeable without specific conversion kits. The orifices (small openings where gas flows into the burner) are sized differently, and the regulators are set to different pressures. Using the wrong fuel can result in inefficient burning, dangerous flare-ups, or even explosions.
Pressure and Appliance Compatibility
Natural gas operates at a much lower pressure than propane. Standard household natural gas pressure is around 4-7 inches of water column (WC), while propane tanks typically hold pressure of 100-200 psi, regulated down to 11 inches WC at the appliance. This pressure differential is critical. Natural gas appliances are designed to operate at a lower pressure, with larger orifices to allow sufficient gas flow. Propane appliances have smaller orifices due to the higher pressure.
Trying to connect a natural gas grill to a propane tank, or vice versa, without proper conversion will lead to dangerous malfunctions. The flame will either be too weak (in the case of trying to use natural gas on a propane appliance) or dangerously large and uncontrollable (when using propane on a natural gas appliance).
Conversion Kits: The Bridge Between Fuels
While not a direct answer to the question of natural gas tanks, conversion kits provide a pathway to using either fuel with a compatible appliance. These kits typically include replacement orifices, a new regulator (if necessary), and detailed instructions.
It’s crucial to use a conversion kit specifically designed for your grill model. Generic kits may not provide the correct components and could compromise safety. It is always best to hire a qualified technician to perform the conversion, ensuring it’s done safely and correctly.
The Reality of Natural Gas Tanks
The short answer is: No, you typically cannot buy natural gas in portable tanks for your grill in the same way you buy propane. This is due to several factors:
- Storage Challenges: Natural gas is difficult and expensive to compress and store in portable tanks at a usable pressure. Liquefying natural gas (LNG) requires extremely low temperatures (-260°F or -162°C), making it impractical for consumer-level portable tanks.
- Infrastructure Limitations: The infrastructure for dispensing natural gas into portable tanks doesn’t exist on a widespread scale. Propane filling stations are common, but similar facilities for natural gas are rare.
- Safety Concerns: Handling and transporting compressed or liquefied natural gas presents significant safety challenges. The risk of leaks and explosions is higher compared to propane.
Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG)
While portable natural gas tanks for grills are not common, Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) are used in other applications, such as vehicles and industrial processes. CNG is natural gas compressed to less than 1% of its volume at standard atmospheric pressure. LNG is natural gas that has been cooled to a liquid state for storage and transportation.
These forms of natural gas require specialized tanks and fueling infrastructure. While CNG vehicles are becoming more common, CNG tanks for grills are still not readily available for home use. LNG is primarily used for large-scale transportation and industrial applications, not for portable grilling.
Why Propane Dominates Portable Fuel
Propane’s properties make it ideally suited for portable tanks. It’s easily liquefied under moderate pressure, allowing for efficient storage and transportation. The infrastructure for filling and distributing propane tanks is well-established, making it readily available to consumers.
Propane tanks are also relatively safe when handled properly. They are equipped with safety valves to prevent over-pressurization, and the tanks themselves are designed to withstand significant impact. This is not to say propane tanks are without any risk, but the industry has standardized the use and handling of propane to minimize those risks.
Exploring Alternative Solutions for Natural Gas Grilling
While you can’t readily buy natural gas in portable tanks, there are alternative ways to enjoy the benefits of natural gas grilling:
- Direct Natural Gas Line: The most common and convenient solution is to connect your grill directly to your home’s natural gas line. This requires a professional plumber to install a gas line to your outdoor grilling area.
- Natural Gas Generators: If you need a portable power source, consider a natural gas generator. Some models can be connected to your home’s natural gas line, providing a reliable source of electricity for outdoor events.
- Propane Grills with Conversion Kits: As mentioned earlier, you can convert a propane grill to run on natural gas using a conversion kit. This allows you to connect your grill to your home’s natural gas line while still retaining the flexibility of using propane if needed (though you would need to switch it back).
Considerations for Direct Natural Gas Line Installation
Installing a direct natural gas line involves several key considerations:
- Professional Installation: It’s crucial to hire a licensed plumber to install the gas line. Improper installation can lead to gas leaks, which are extremely dangerous.
- Permits and Inspections: Most municipalities require permits for gas line installations. The installation must also be inspected to ensure it meets safety codes.
- Distance and Pipe Size: The distance from your gas meter to the grill affects the required pipe size. Longer distances require larger pipes to maintain adequate gas pressure.
The Future of Natural Gas Grilling
While portable natural gas tanks for grills remain uncommon, technological advancements could potentially change this in the future. Innovations in gas storage and compression technologies might lead to more practical and affordable solutions for storing and transporting natural gas.
However, for the foreseeable future, connecting your grill directly to a natural gas line or using a propane grill with a conversion kit remain the most viable options for enjoying the benefits of natural gas grilling. The convenience and safety of propane tanks continue to make them the dominant choice for portable grilling fuel. The future might hold new developments, but understanding the current landscape helps you make informed decisions about your grilling setup.
When considering any changes to your gas appliances, consult with qualified professionals to ensure safety and compliance with local regulations. Enjoy your grilling season safely and deliciously.
