Regenis Clean Water System Cover Story In Progressive Dairyman

Progressive Dairyman took a look inside the Regenis Even Flow Clean Water System and shared the story with its readers in their February 25th issue.

The membrane system, which was installed on the dairy last fall, uses nano-filtration and reverse osmosis to extend membrane life to reduce operational costs as well as producing water clean enough for animals to drink or use on the farm. Not only will this system reduce lagoon storage needs, but it will allow for increased herd size without a new source of water. It’s a turnkey automated system and is fully remote.

Craig Frear Teaches Biogas Course

Our Director of Research and Technology, Craig Frear, was a key instructor in the 2nd American Biogas Council (ABC) West Coast Operators Training Course. The three-day course was held in San Francisco, California from February 26-28, 2019.

Twenty-two students were taught key principles behind anaerobic digestion systems, including anaerobic digestion theory, chemistry, and math with operator focused training on digester upsets, odors mitigation, and RNG, primary separation, secondary separation and nutrient recovery operations.

Dr. Craig Frear touring anaerobic digester facilitiesStudents were also treated to special tours of 3 separate digester facilities in the area—the Blue Line CNG Facility in South San Francisco; the Zero Waste Energy Facility in San Jose; and the East Bay Municipal Utility District Co-Digestion Anaerobic Digester Facility in Oakland.

Craig had a wonderful time interacting with the students, ABC staff and fellow instructors Bernie Sheff and Dan Waineo. The three facility tours were also excellent and indicative of the diverse technology, approaches, roles and outputs present within our industry.

Seattle NBC Affiliate: From Cow Waste To Clean Water

Seattle’s NBC affiliate, KING-5 showed its viewers how Regenis is processing manure from Coldstream Farms, and returning clean water back to nature with the goal of helping the flow of local salmon streams.

Regenis’ Projects Finalists For Biogas Industry Awards


Two of the eight finalists for Project of the Year were built by Regenis.


Ferndale, WA– Two Whatcom County dairy digester projects built by agricultural waste solutions company, Regenis, have been nominated as finalists for the American Biogas Council’s Project of the Year Awards, which will be handed out at a ceremony on October 16th in Raleigh, North Carolina.

The event, which takes place during Biocycle Refor18, showcases innovative approaches, technologies or partnerships which advance the biogas industry. Eight projects across the United States were nominated for the four awards to be given out that evening including Edaleen Cow Power and FPE Renewables, both located in Lynden, Washington.

Regenis installed the FPE digester at the Vander Haak Dairy in 2004. It was the first dairy digester in Washington State and has had a historic 13-year runtime until this past year when upgrades to its roof were completed. The mixed plug-flow digester captures methane from the dairy waste stream and converts it into clean biogas while destroying 99 percent of the pathogens and bacteria.

The Edaleen mixed plug-flow digester was installed in 2012 and also has a 100 percent runtime. Like FPE, pathogens and bacteria in the waste stream are destroyed in the digestion process while the biogas created from capturing methane in the waste stream is sold to the local utility.

Additionally, Regenis installed a fine solids separation system at the dairy in 2017, which removes over 90 percent of the suspended solids in the post-digestion waste stream and 90 percent of the phosphorous, which is key to protecting local salmon streams and watersheds.

Dr.Craig Frear, Regenis’ Director of Research and Technology, will be attending the event on behalf of the company.

Cows To Cars? It’s Happening

Creating a highway humming with hydrogen cars has been a dream of scientists, policymakers and environmentalists for decades. Today, thanks to the dairy cow, we are closer than ever to making it a reality.

One of the biggest hurdles in creating hydrogen fuel until now has been the enormous amount of fossil fuel-based energy it takes to extract hydrogen from water or hydrocarbons.

Most hydrogen fuel is produced via steam methane reforming where natural gas reacts with steam in a catalytic converter to produce hydrogen gas as well as carbon dioxide. Water electrolysis, another highly utilized process, uses an electric current to separate H2O into hydrogen and oxygen gas, but it too, requires significant amounts of fossil-fuel derived electricity.

Exit the Cow

It’s well known that dairy cows contribute significantly to methane (a very potent greenhouse gas) release, both from their burps and management of their manure. as waste exits their systems, and some dairy farms have installed anaerobic digesters to capture and use as renewable energy. Inside the digester’s airless tank, organic matter is converted into biogas, which in turn can fuel combustion engines to power the farm or grid.

However, biogas does not have to power a generator. Thanks in large part to California’s emission reduction targets, a financial market is developing for biogas, scrubbed of impurities, to be injected straight into natural gas pipelines as a renewable equivalent to fossil natural gas. One use for this renewable natural gas (RNG) is an input to generate hydrogen gas. While the above-described process has not changed to produce hydrogen, the CO2 emission reductions from this renewable approach are significant.

Enter The Car

Toyota has gone all in with its efforts to take hydrogen gas—sorry—the last mile to zero emissions. Their innovation is to pump the renewable natural gas directly into a fuel cell, which is like a giant battery. This battery, though, generates both hydrogen and electricity, as well as the heat and water to catalyze the reaction.

Not all of hydrogen’s hurdles are solved. For example, there are only 39 hydrogen fueling stations across the United States, and of those, 35 are in California. Hundreds more are required before Americans invest in cars dependent upon this new technology.

Consumers will also presumably want to fuel their cars for less than $5.60 per gallon, the current cost of hydrogen fuel. Additionally, America is far behind the curve when it comes to capturing methane to create biogas. Europe, for example, had 12,496 animal waste digesters in 2016 compared to the 281 in the U.S. as of April 2018.

With the right policies encouraging methane capture from cows, the National Renewable Energy Laboratory calculates that 486,000 metric tons of hydrogen or 477 million gasoline gallon equivalents could be generated annually from dairy digesters throughout the U.S—enough to supply the annual fuel needs of nearly 730,000 U.S. drivers.

With General Motors and Honda partnering to bring their hydrogen model to market to compete with Toyota, the potential is there for huge advances in a hydrogen fuel economy, relying in part on our nation’s dairy cows to commit to their duties on a daily basis.
