Feasibility Of Using Natural Gas Cogeneration For Greenhouse Power, Heating And Co2 Enrichment

Abstract

Cogeneration technology, known for energy efficiency, low energy costs and low greenhouse gas (GHG) emissions, generates both heat and power. Carbon dioxide (CO2) is also produced and is typically vented. However, the potential exists to use the CO2 to promote plant growth in a greenhouse. The objective of this evaluation is to determine whether a one‐megawatt (MW) natural gas cogeneration unit is a technologically, environmentally and economically feasible method to provide power, heat and CO2 enrichment to the Blood Tribe Agricultural Project’s (BTAP) proposed greenhouse. Furthermore, to assess the feasibility in using light‐emitting diode (LED) lights to further enhance energy efficiency. Through data collection and analyses, this evaluation will compare technologies, determine GHG emission reductions and corresponding carbon offset credits, determine natural gas requirement reductions for heating, and assess financial feasibility. Ultimately, the research concludes that cogeneration is not preferred for BTAP’s proposed greenhouse, but offers recommendations for future research.
