When B.C.’s clean energy pioneer Quadrogen Power Systems was founded, producing four useful products from sewage or landfill gas was world-beating technology, thus the inclusion of “quad” in its name.

“At that time in 2007, the most anyone had done in the world was three — trigeneration — but we are now going to make six products in Delta,” said founder and CEO Alakh Prasad. “Some people are calling it sexgeneration, but I think it needs a new name.”

Quadrogen has created a system to clean gas from the City of Vancouver’s landfill for a $7.5-million quadgeneration project run by FuelCell Energy at Village Farms’ massive greenhouse complex in Delta.

At the time of its conception, Prasad called the quad “game-changing.” Well, the game has changed again.

“We originally designed the Delta plant to produce four products — electricity, heat, hydrogen and carbon dioxide — to enrich the atmosphere inside the greenhouses,” he said. “That’s quadgeneration. Now are going to add biodiesel and biomethane.”
