Houwelings Tomatoes

See how Houwelings Tomatoes uses Combined Heat and Power technology to conserve water and reduce emissions.

This greenhouse grower of premium tomatoes and cucumbers utilizes Combined Heat and Power technology for significant energy savings.

Large natural gas-powered engines generate electrical power – and the exhaust from the engines creates CO2, which is captured and purified and then piped into the greenhouses as fertilizer. The heat produced from the engines is captured in thermal storage tanks and used to heat the greenhouses. Then the water from the exhaust is condensed and used to water the tomatoes in the greenhouses.

  • They produce enough electricity to power their full operations, and supply enough energy back to the local community grid to power 8,800 local homes.
  • The system has diverted more than 21,000 tons of CO2 emissions and converted it into fertilizer—that’s the equivalent of taking 4,000 cars off the road.
  • The system allows Houweling’s to conserve 9,500 gallons of water every day—this is critical in a region that has been struck by a multi-year drought.
