Converting Biogas To RNG

Renewable Natural Gas Is The New California Gold Rush

California's carbon credit market and low carbon fuel standard (LCFS) incentivize natural gas utilities and fuel suppliers to produce or acquire low carbon substitutes for fossil fuels for heating homes and transportation.

Biogas from dairy waste isn't just a low carbon energy source; it's a negative carbon emission energy source. As a result, it's become more valuable for dairy digester owners to convert it into renewable natural gas (RNG) and inject it into a gas pipeline instead of turning it into clean electricity and selling it to a utility.

Upgrade to RNG

Biogas conversion requires specialized knowledge because raw biogas isn’t clean enough to meet natural gas pipeline standards.

Our team of skilled tradesmen have already installed gas upgrade systems for three dairy digester projects that were originally built to produce clean electricity.

Let us help you get into the biogas pipeline.

Meet Your Gas Utility’s Standard

Every utility has different specifications that must be met before accepting RNG into their pipelines, and no one single gas upgrade system will meet the requirements of every utility. We aren’t tied to any particular gas upgrade technology or vendor because we think it’s important to serve the best interests of our clients first.

“Renewable natural gas is the next generation of green energy solutions that satisfies the increasing demand for cleaner energy resources. In a competitive market it is an imperative to partner with industry proven professionals. Leyline has chosen the Regenis team to leverage Regenis’ technical, construction, and operation expertise to ensure project success. They are a trusted partner and provide sound, professional support in all phases in the project life cycle.”

“Regenis had already built our digester and kept it running continuously for six years so we had confidence hiring them to build our fine solid separation system. Now we’re able to remove phosphorous and nitrogen from our liquid waste stream, apply nutrients to our crops more precisely and reduce the amount of liquid we have to haul off the farm.”

“We were considered pioneers when we built the first digester in the state two decades ago, and we’ve partnered with Regenis from the beginning not just because of their technical expertise, but also because of their tradition of honesty and integrity. Throughout the last 20 years, we’ve viewed them as our partner as we’ve experimented with cutting edge technologies. Our ongoing efforts together have allowed us to upgrade power output by 25 percent and identify a string of new products.

“Craig Frear and the team at Regenis have supported the American Biogas Council for more than a decade with their deep knowledge and technical expertise on the design and operation of anaerobic digesters. As a result, we are providing a better service to the biogas industry and countless developers, operators, and digester owners are producing more biogas than they would have without Regenis.”
