Renewable natural gas for a sustainable future
When biodegradable materials decompose, they release methane, which can be captured and converted into renewable natural gas (RNG). This process provides a renewable and clean energy source, making RNG is a valuable addition to your sustainability strategy.
Since methane is the main component of natural gas, RNG can be used interchangeably with natural gas derived from fossil fuels and in natural gas engines. Alternative fuels like RNG can help you meet regulations and adopt cleaner energy.
Experience the benefits of adopting RNG
Maintain performance and scalability while reducing GHGs and CO2 emissions with RNG, a cleaner alternative to conventional natural gas and fossil fuels.
Comparable to diesel
RNG delivers similar power and reliability while operating more quietly and with a reduced environmental impact.
Offsets fuel costs
Because RNG can often be produced domestically, RNG offers pricing stability and can help companies eligible for the US EPA’s renewable fuel standard program drive fuel cost savings.
Provides flexibility
RNG helps reduce net carbon emissions while producing heat, generating electricity, and powering your fleet.
Leverages existing infrastructure
Our refueling network eliminates the need to build new infrastructure and enables a seamless transition to RNG.

Shell Starship 3.0, one of the most aerodynamic tractor-trailers on the road, has moved beyond test routes and into the high-performance world of INDYCAR. It now serves as a key member of the racing series’ transportation fleet. Powered by the Cummins X15N™, the cleanest heavy-duty natural gas engine on the market, Starship 3.0 is demonstrating that natural gas technology is not just a re
As more truck engines using alternative fuel enter the market, including the Cummins X15N, more repair shops are weighing their options for providing indoor service in a properly outfitted facility. There is good news for technicians who often work outdoors to be code compliant for gaseous truck service. Getting techs indoors means deciding between converting an entire garage to
Companies aiming to minimize their environmental impact are prioritizing Scope 3 emissions—those generated across their entire value chain, including suppliers, contractors and transportation. Often the largest share of a business’s carbon footprint, these emissions present significant challenges, particularly for industries like manufacturing, food production, retail and shipping. Renewable Natur
As sustainability becomes a global priority, companies are exploring ways to cut greenhouse gas emissions across their entire operational footprint. This includes Scope 1 emissions directly under their control, like manufacturing processes. But companies can make a big impact by looking at ways to lower indirect emissions, known as Scope 3. Many companies in industries like food production, manufa
The Cummins Inc. X15N is the most powerful natural gas engine Cummins has ever built, with a broad engine torque curve to provide flexibility for various heavy-duty applications. The X15N weighs less than our current X15 diesel and has power ratings up to 500 hp and torque up to 1850 lb-ft, helping heavy-duty fleets start reducing their transportation emissions today, without sacrificing capabi
A decade ago, turbochargers for natural gas and diesel engines were not very different. However, new emissions regulations have driven the development of turbochargers specifically designed for natural gas engines. These turbochargers are adapted to stoichiometric burn conditions, where the mix of oxygen and fuel is precisely balanced. This balance ensures efficient combustion, leaving no unburnt
At Cummins Inc., we’re constantly looking for ways to advance sustainable transportation solutions. As the industry shifts to lower-emission fuels to reduce pollution, natural gas engines are one critical pathway to cleaner mobility. Cummins is therefore working to innovate component-level technologies supporting natural gas engines. Understanding how natural gas engines work and the components
As the transportation industry shifts towards sustainable operations, a strong, reliable and extensive service network is essential for keeping vehicles on the road and fleets operating at peak performance. Service networks help fleets stay on the road faster and increase uptime (amount of time that a vehicle is available and operational for use) while also integrating advanced telematics and pred
Renewable natural gas FAQs
RNG is sometimes known as biomethane or upgraded biogas. When biodegradable materials decompose, they release methane and undergo aerobic digestion, a process in which bacteria break down organic matter. This process produces organic materials like biogas, which can be captured and converted into natural gas. With only a minor clean-up and refinement, biogas can generate heat and electricity.
RNG differs from fossil fuels because it's produced from biodegradable waste. When these biodegradable materials decompose, methane is released. This methane is then captured and converted into RNG. Because methane is the primary component of natural gas, RNG is interchangeable with natural gas derived from fossil fuels.
Methane is the primary component of RNG, which is chemically almost identical to conventional natural gas. However, RNG is carbon-neutral because it originates from fermented organic waste, such as sewage sludge or animal manure. Depending on the energy source, the carbon intensity of RNG can even be sub-zero.
Experts use a carbon negative index to assess the environmental impact of various fuels. A fuel is considered carbon-negative when it reduces the amount of carbon dioxide (CO2) in the atmosphere. The carbon intensity of RNG depends on the type of feedstock used to produce it. This means where the RNG derives from determines its place on the scale and whether or not it's considered carbon negative.
