Seabreeze Farm completes RNG equipment upgrade with DMT

DMT Clear Gas Solutions’s RNG facility at Seabreeze Farm in Canada is now operational.

The third-generation dairy farm owned by the Keulen family in British Columbia was previously using water wash technology to convert biogas into RNG. Now, the RNG facility uses DMT’s three-stage membrane separation technology, the Carborex® MS.

“We’ve been making manure and food waste a revenue generator since 2014,” said Jerry Keulen, owner of Seabreeze Farm. “With our new DMT biogas upgrading system, we look forward to making RNG more consistently.”

The facility upgrades 180 standard cubic feet per minute (SCFM), or 290 Nm3 per hour of biogas generated by 250 milk cows and 12,000 annual tons of off-farm organics. With DMT’s biogas upgrading system, Seabreeze Farm produced up to 99.5% RNG for direct injection into the natural gas pipeline. In terms of greenhouse gas emissions, the project equates to removing 650 vehicles from roadways or generating energy for 360 homes.

Robert Lems, general manager of DMT Clear Gas Solutions, said: “Completing this dairy RNG project during the pandemic certainly proved challenging.

“We are thankful to Jerry, our internal team, and all local companies involved for making this project a reality. This is the first DMT biogas upgrading facility of many in Canada. A second system in Ontario will be commissioned soon.”

Seabreeze Farm continues to sell the RNG to FortisBC, a natural gas and electricity utility that serves British Columbia’s 1.2 million customers.

Canada is in a strong position to achieve net-zero emissions by 2050 through its Clean Fuel Standard, which aims to drive investment and growth in the country’s clean fuel sector. Final regulations for the CFS will be published in late 2021 with the regulatory requirements in force by December 2022. According to the Canadian Biogas Association, the nation can tap more than eight times its current biogas and RNG production.
