Consulting-Specifying Engineer goes in-depth on the use of CHP systems in commercial greenhouses. As you probably remember from high school biology, green plants feed on carbon dioxide from the air and water from the ground to grow. “Extra CO2 to augment the level inside the greenhouse can be sourced in a number of ways, including exhaust gases from heating and, less frequently, the administration of pure CO2 purchased commercially,” the article reports. “However, CHP makes it possible for the required CO2 to be obtained from the exhaust gases of a gas-fueled engine.” To make the system safe for plants, the exhaust gases are treated to reduce the levels of nonmethane hydrocarbons and nitrogen oxides.
