Sturgeon Bay, WI – Despite pandemic restrictions and the anticipation of delay, DMT Clear Gas Solutions, a
leading technology supplier in biogas upgrading and gas desulfurization, announces its second and third
renewable natural gas (RNG) projects with Nacelle Solutions, a provider for gas conditioning technologies and
service for the energy and biogas industries, are operational. The Dallmann East River Dairy project in Brillion,
WI and the S&S Jerseyland Dairy project in Sturgeon Bay, WI are part of a series of four projects converting
dairy manure into RNG.

“Since the first announcement regarding the completion of the Clover Hill Dairy project back in April, our
dedicated team persevered through the coronavirus pandemic to complete a short delivery time,” said Robert
Lems, general manager of DMT Clear Gas Solutions. “Our plan to deliver four back-to-back projects in less than
a year is no easy feat. I am thankful to my team, Nacelle Solutions, U.S. Gain and all parties involved for
breaking new ground in our industry.”

Between all four farms, the projects will upgrade a total accumulation of 1000 standard cubic feet per minute
(scfm) of biogas to produce up to 99.5% pure RNG for direct injection into the natural gas pipeline. Together,
these farms will produce enough RNG to fuel greenhouse gas emission savings equivalent to removing more
than 3,100 vehicles from U.S. roadways for one year or CO2 emissions from 1.6 million gallons of gasoline.
“Nacelle is pleased to bring more plants online and further the environmental benefits provided by the RNG
industry,” said Gov Graney, co-owner of Nacelle Solutions. “With these plants, there were many unforeseen
challenges during construction and commissioning presented by COVID 19 and having a strong team of
vendors, like DMT, that can adjust and solve problems on the fly was critical to our success.”

Nacelle Solutions was contracted to coordinate biogas upgrading efforts for anaerobic digesters owned by U.S.
Gain
, a leader in the development and distribution of RNG for the transportation and thermal energy markets.
RNG produced at the farms will be transported using a virtual pipeline to one centralized injection point.

“U.S. Gain is committed to the continued development of RNG at dairy farms because of the incredibly low
carbon fuel that can be produced,” commented Mike Koel, president of U.S. Gain. “We’re proud to have
industry-leading companies like Nacelle Solutions and DMT Clear Gas Solutions working with us to expedite gas
development for growing market demand.”

Through biogas upgrading, trace impurities in the biogas stream are removed and carbon dioxide (CO2) is
separated from methane (CH4) to produce pipeline-spec RNG suitable for injection into the natural gas grid
and/or direct use for vehicle fuel. The benefits of RNG include the reduction of greenhouse gas emissions,
increased domestic energy security, improved waste management, new revenue sources for American farmers,
and more jobs in rural areas.
