From waste to watts: how to monetize stranded gas.

Each year, U.S. oil and gas operations flare or vent enough natural gas to power 9.5 million homes. They call it waste. But there’s another, more accurate term: lost revenue.

This happens at oil and gas facilities when gas can’t be economically captured and used. Coal mines, dairies, and wastewater treatment facilities face similar challenges with methane and biogas. For the owners and operators of pipelines, production plants, or other gas-processing facilities, every cubic meter of gas flared or vented represents money that could have been saved or earned. 

The cost of business as usual.

Here’s a specific example of how an industrial operation can boost its revenues by reimagining waste. 

Midstream oil and gas companies make money by moving gas through their pipelines. Compressor stations boost gas pressure to keep it flowing quickly and efficiently. When not connected to the grid, those compressors are typically powered by turbines or reciprocating engines that are fueled by natural gas that would otherwise be moving through pipelines and generating revenue. Instead, midstream operators are forced to siphon off the valuable product they are selling to run their operations.

It doesn’t have to be this way. Compressors and pipelines are often located next to drilling facilities that produce “non-standard” gas, or gas that would either be flared or need expensive cleaning to be pipeline-ready. Instead, that non-standard gas could be converted into electricity on-site to power those compressors, eliminating the need to flare, vent or use pipeline-quality gas. 

This same basic opportunity is also available to coal mine operators that flare methane and landfills that produce methane from decomposing waste but often flare the gas because they lack efficient ways to use it. Dairy operations and wastewater facilities produce biogas that is typically flared or vented rather than captured and turned into useful energy. Put simply, many industrial operations sit on potential fuel sources that are a cost, not a source of revenue.

How to capture value from non-standard gas. 

Industrial operations have several pathways to monetize gas that would otherwise be wasted. Here are two options:

Option 1: Displace purchased electricity. 

Prices for grid electricity are rising quickly around the country. Industrial operations can mitigate the risk of price increases by generating their own power on-site. For example, Napa Sanitation District in California now uses biogas from its wastewater treatment process to power linear generators, reducing its dependence on grid electricity. Because the facility now supplements its existing cogeneration assets to convert biogas into electricity, it can accept more waste fats, oils, and grease, creating a virtuous cycle in which it produces even more biogas to fuel generators and reduce electricity costs. California Bioenergy has deployed the same approach across dozens of dairy locations, using captured biogas to power operations while improving project economics for its dairy farm partners. In Chattanooga, Tennessee, the Moccasin Bend Environmental Campus is converting wastewater methane into on-site electricity, reducing both its energy costs and flaring. 

Option 2: Sell power to emerging markets. 

The explosion of data center development has created an unprecedented demand for extremely reliable electricity–demand that utilities struggle to meet. For midstream gas companies, more data centers mean more customers for their natural gas. But it also can mean owning and operating generation assets that provide power directly to data centers. The opportunity isn’t just to sell fuel. It’s selling power to customers with a huge and growing appetite for it. Major pipeline operators have announced plans to develop generation assets specifically to serve data center load, a recognition that the value of their gas extends beyond the pipeline.   

Technology enablers. 

Converting waste gas to electricity has always been theoretically possible. What is new is the emergence of versatile generation technology able to be deployed quickly. 

For decades people have known that linear power generation is the most efficient way to convert energy to electricity. But its promise has only been realized recently with advances in technology, specifically, power electronics and advanced software. The result is something orders of magnitude simpler than a conventional engine or turbine. 

What linear generators deliver.

Fuel flexibility: Non-standard gas from oil and gas operations, coal mine methane, and biogas all have different characteristics than pipeline-quality natural gas. Traditional turbines and engines either can't run on these fuels, require expensive gas cleanup, or cannot accommodate fluctuating gas changes on the fly. Linear generators can handle significant fuel variability, reduce cleanup costs, and make previously uneconomic projects viable.

Speedy deployments: Many traditional generation technologies, like gas turbines, face multi-year backlogs. Linear generators do not. For industrial facilities seeking to capture the data center opportunity, being operational in 12 months rather than years means capturing revenue that would otherwise be lost. In nonattainment areas—regions that fail to meet EPA air quality standards—low-emission technologies like linear generators also move through permitting faster.

Low emissions: Linear generators convert fuel into electricity at temperatures below which nitrogen oxides (NOx) form. This means linear generators produce near-zero NOx emissions, allowing speedy permitting even where air quality standards are most stringent. 

Four essential questions to better understand your opportunity to monetize waste gas:
 

1. "What's the total gas volume we're currently flaring or venting?"

Quantify the opportunity. Even small volumes can generate meaningful electricity.

2. "What would it cost to clean gas to pipeline standards?"

When fuel-flexible technology eliminates expensive gas cleanup, the economics change dramatically.

3. "Could we sell power to nearby facilities or into markets?"

With data centers hungry for reliable power and capacity markets reaching record prices, industrial sites with consistent gas supplies have new revenue opportunities.

4. "What happens in 10-15 years?"

Choose technologies that can adapt to future fuels like hydrogen or renewable natural gas.

The industrial facilities that thrive will be the ones that stop viewing non-standard gas as waste and start seeing it as value to be captured. The math is straightforward: every cubic meter flared is electricity not generated and money not earned or saved. But a far better story is possible. Industrial facilities that capture and use non-standard gas win multiple times–turning a potentially costly liability into reliable power while reducing costs and cleaning their operations all at once.
