Farm digesters and waste water treatment plants are key vertical markets for the Capstone CR200 200kW renewable energy product, the company said.

Capstone claims that its microturbines are capable of burning waste gases with methane content as low as 30%. The CARB waste gas emissions requirements are achieved with the company’s low premix combustion technology inherent to the microturbine and require no exhaust after treatment.

Jim Crouse, executive vice president of sales and marketing at Capstone, said: “California farm digesters and waste water treatment plants are a great market opportunity for our products. We are excited to offer our customers a product that is accepted by the state of California and supports our home state’s aggressive sustainability initiatives.”

Darren Jamison, president and CEO of Capstone Turbine, said: “Renewable energy applications like waste water treatment plants and farm digesters are a core part of Capstone’s business as governments continue to implement sweeping renewable portfolio standards.

“Certification of the CR200 to these extremely stringent standards allows Capstone to continue to expand its market penetration into even larger projects and continues to prove that Capstone is an industry leader in ultra low combustion emissions.”
