DMT Clear Gas Solutions will update renewable natural gas (RNG) equipment at Seabreeze Farm, a third-generation dairy farm in British Columbia (BC), Canada.

Seabreeze Farm, owned by the Keulen family, will update their RNG equipment using DMT’s patented three-stage membrane separation system. The farm made headlines in 2015 when the owners announced they had combined anaerobic digestion (AD) with a biogas upgrading plant. DMT says the farm owners’ decision to update their biogas upgrading equipment is “on-trend to what analysts have witnessed over the last five years: that membrane separation is the prevalent technology used in North America’s RNG industry”.

Thanks to the Seabreeze Farm project, the RNG generated from dairy manure produced by 250 cows and 12,000 tons annually of off-farm organics, is enough to heat around 350 homes. In Canada, biogas production from all major source including agricultural organics, municipal wastewater, landfill gas and separated organics, is equivalent to 3% of the country’s natural gas demand.

Robert Lems, general manager of DMT Clear Gas Solutions, said: “We are thrilled to announce the Carborex®MS, our innovative membrane separation technology, into the Canadian market. Seabreeze Farm will find that our membrane system is easier to operate and will free up time originally spent on operation and maintenance.”

The project will upgrade 180 standard cubic feet per minute of biogas to produce more than 98% pure RNG. The RNG will be sold to FortisBC, a natural gas and electricity utility serving over 1.2 million customers in BC. On direct injection into their natural gas system, FortisBC will operate the interconnection, monitor gas quality and distribute the energy to BC residents and businesses.

“RNG is a crucial component of our 30BY30 target, which is our goal to reduce customers’ greenhouse gas emissions by 30% by 2030,” said Scott Gramm, manager of RNG supply with FortisBC. “Increasing the amount of renewable gases in our infrastructure is paramount to a lower carbon future and I want to thank Seabreeze Farm and DMT Clear Gas Solutions for their leadership in climate action.”
