Californian company Capstone Turbine has secured a 400kW microturbine sale to power a biogas project in France. The order for the lightweight and compact 3-bay C400 Signature Series package was secured by Biogaz Services, Capstone’s distributor for renewable energy in France.

The microturbine package will operate on renewable biogas from methane generated from agricultural green waste, cow manure and pig manure. The Capstone C400S will be coupled with an exhaust-fired heat exchanger and will use the biogas to produce electricity that will be put back into the local grid. The thermal energy generated from the microturbine exhaust will go to a nearby hospital.

Renewable energy has traditionally been Capstone’s third-largest market vertical and represented around 7% of its revenue in 2019. In May this year, the firm announced a 9.6MW renewable energy biogas order, the largest received by Capstone in the company’s history.

Darren Jamison, Capstone’s president and CEO, said: “Capstone is excited to be an essential part of the development of these biogas projects and helping create renewable biogas-to-energy and renewable natural gas-to-energy projects as the new fuels of choice in the green economy.”

“Capstone microturbines were the logical choice as our technology is flexible with the ability to turn units off to match variations in the methane that is produced,” added Jim Crouse, executive vice-president of sales and marketing at Capstone. “This built-in flexibility also provides higher efficiency compared to a single, large traditional power generation solution.”
