Sioux City, Iowa recently made national headlines with a plan to turn organic waste into marketable Renewable Natural Gas (RNG) through a wastewater treatment plant improvement project. The project, expected to pay for itself in just three years, will produce almost 2.1 million gallons of gasoline offset annually. This RNG will be marketed to generate revenue and avoid utility rate increases for local citizens.

Many other cities are identifying this as a lucrative market opportunity. It disposes of organic waste through the anaerobic digestion process to create purified biogas, which can then be marketed for vehicle fuel and converted to revenue.

“By connecting to existing natural gas pipelines, cities have the ability to contract with buyers anywhere in the country and seek the best terms available,” said Phil Gates, biogas project manager for Bartlett & West. “Sioux City’s plan is expected to pay for itself within three years.”

How renewable natural gas is marketed

To be ready for market, raw biogas has a few constituents that need to be removed — carbon dioxide, nitrogen, moisture, hydrogen sulfide and siloxanes. Primary purification options include pressure swing adsorption, membrane separation or scrubbing with water or amines. For the purified biogas to be distributed, it is important to factor in compression capabilities and pipeline connectivity.

In Sioux City, Bartlett & West worked to navigate regulations while maximizing the efficiency and effectiveness of the infrastructure.

“By connecting cities and industry with biogas solutions, Bartlett & West helps turn our clients’ byproducts into potential profits through the market that is driven by vehicle fuel regulations,” said Jeremey Lay, wastewater treatment project manager at Bartlett & West. “When planning biogas conversion, a comprehensive approach is key, from design of the actual infrastructure to successfully driving revenue by taking biogas to market.”

Biogas has been utilized within wastewater treatment plants for decades. However, the value of biogas and the environmental credits associated with biogas has risen exponentially in recent years.

“It is an exciting time within the wastewater industry,” said Jeremey Lay, wastewater treatment manager at Bartlett & West. “The industry’s focus used to be on effluent quality and biosolids disposal, but the focus has shifted to water reuse and resource recovery. For years many of our customers have been interested in being sustainable, but new resource recovery revenue streams and technological improvements are turning their ‘green ambitions’ into profitable solutions.

Vehicle fuel regulations are driving the market

The Renewable Fuel Standard (RFS) launched in 2007 to promote the development of renewable fuel markets such as corn ethanol and soy biodiesel. The RFS mandates that increasing percentages of the vehicle fuels used in the United States be from renewable sources. The RFS was modified in 2012 to include other biofuels such as biogas to spur additional biofuel growth.

These renewable fuels are given a renewable identification number (RIN), which is used to identify and track biofuel. Obligated parties under the RFS, such as petroleum fuel producers and importers, have to purchase and blend in biofuel in order to comply with the mandate.

How to create biogas revenue

The natural gas pipeline network stretches throughout the United States. By feeding purified biogas into this network, organizations can receive a share of eventual proceeds based on RIN purchases. In addition, the states of California and Oregon have significant demand for purified biogas because of the state-run Low Carbon Fuel Standard programs. A similar program is currently under consideration by the state of Washington, as well as a non-profit consortium from the states of Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island and Vermont.

The state of California’s Low Carbon Fuel System program has met its goals, but the state recently passed legislation to significantly reduce greenhouse gas emissions by the year 2030. The plan specifically targets a 50-percent reduction of petroleum use in vehicles, which is significant given the prominence of California’s economy relative to the global economy.

RFS legislation creates a significant market opportunity over the next five to 10 years — one that enjoys bipartisan legislative support. As a national leader in biogas conversion, Bartlett & West offers individual consultations to advance communities and industry toward capitalizing on this thriving market.
