CNG Fuel Savings
What is CNG?
Between rising gas prices and government regulations to reduce emissions that go into effect in 2035, big rig diesel engines will soon be a thing of the past. Compressed natural gas (CNG) can help you meet those requirements and save money at the same time. Use cutting-edge technology to retrofit your diesel rigs to run clean energy with our Compressed Natural Gas Conversion Kits.
CNG Benefits
BENEFIT 1
Increased Hauling Power & Reliability
CNG delivers stronger torque and smoother engine performance—ideal for buses and fleet vehicles that need to carry heavy loads over long distances. Whether it’s transporting students safely or moving goods efficiently, CNG ensures reliable power and consistent performance on every route.
BENEFIT 2
Lower Operating Costs & Emissions
GES energy solutions cut fuel and electricity use, reducing monthly operating costs while helping organizations meet sustainability goals. Schools benefit from more room in the budget. Fleets gain long-term savings and a greener footprint—without sacrificing performance.
BENEFIT 3
Longer Equipment Life, Less Downtime
Clean-burning CNG reduces engine wear, while geothermal HVAC systems run with less strain. The result? Lower maintenance needs, fewer breakdowns, and longer-lasting equipment. Both school districts and private fleets can count on better uptime and reduced repair expenses:
Step 1: Evaluate Infrastructure & Fleet Needs
GES designs a custom CNG plan based on your fueling setup and vehicle requirements.
Step 2: Secure Incentives & Maximize Savings
Our experts find funding opportunities to reduce costs and boost long-term value.
Step 3: Ensure Reliable Service & Support
Certified techs provide ongoing maintenance to keep your CNG systems running strong.

Frequently Asked Questions
Currently heavy trucks running on diesel have no feasible option for being powered by electricity. Electric vehicles have a short range between charges, whereas a diesel can go 1,000 to 1,500 miles. RNG would not affect the distance rate for driving.
Hypothetical scenario: a fleet of 50 diesel vehicles that drive 500 miles a day with a fuel mileage of 12mpg could produce 1.1 million pounds of CO2 LESS than traditional engines.
When the engine is under a high load, it will use a higher percentage of RNG than when the engine is under a lighter load.
The kit can displace up to 30% of diesel fuel.
By adding a CNG conversion kit, users will expect a longer equipment life and increased engine efficiency. By burning less diesel and more renewable natural gas, you can continue using your vehicle while reducing carbon emissions and lowering fuel costs.
Conversion kits include a tank package suitable to a particular vehicle, plus hoses, tubes, fittings, pressure regulator, fuel delivery system, sensors and processors.
Diesel engines will gain power and gas engines will remain the same.
We currently ship to the continental 48 states. We hope to service Alaska and Hawaii in the future.

Yes, it improves mileage from straight diesel.
CNG supplements diesel, just like electric, vehicles also use gasoline.
At about $1.49 a gallon, CNG is significantly cheaper than regular gas prices.
CNG tanks are DOT-certified.
The vast majority of natural gas in the United States is considered a fossil fuel, because it is made from sources formed over millions of years by the action of heat and pressure on organic materials. Renewable natural gas (RNG) is a pipeline-quality vehicle fuel. It is produced by purifying biogas, which is generated through anaerobic digestion of organic materials—such as waste from landfills and livestock—or through thermochemical processes, such as gasification. RNG qualifies as an advanced biofuel under the Renewable Fuel Standard.
Renewable Natural Gas is one type of biofuel. Biofuels are derived from plant material or animal waste. It’s considered to be easily replenished, which makes it renewable energy. Fossil fuel like diesel is not a biofuel.
CNG is produced by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. To provide adequate driving range, CNG is stored onboard a vehicle in a compressed gaseous state at a pressure of up to 3,600 pounds per square inch.
