Reuse of flue gas CO2 in Greenhouse Horticulture


Greenhouse farmers are introducing extra CO2 to enhance growth of crops. The CO2 is derived from own energy installations as heating or CHP or supplied as liquefied CO2, CO2 from central CO2 networks such as OCAP (only available in a small area). CO2 is, however, not always available as byproduct, leading to inefficient operation of energy installations or high costs for external CO2. The alternative of no CO2 dosing is not exploiting the full growth potential of plants. This all costs money. Additional CO2 can increase growth to app. 30% extra yield.
Climate change is expected to give more weather extremes. This will increase the stress on use of fresh water resources by farmers. This project aims to provide a solution for both problems. We aim to optimize the use of CO2 in greenhouses in a cheap and low energy manner, by using excess CO2 produced at night and winter time and combine this by exploiting a new water source, being water from flue gasses, and alleviating the stress on fresh water sources. The project Reuse of flue gas CO2 in Greenhouse Horticulture with CO2 buffering using adsorbents combined with water harvesting (CO24G) focusses on:

1. Comparing different types of existing greenhouses with the new system and develop relative benchmarks in terms of climate effect for different scenarios (north/ south Europe, centralized/ decentralized CO2 supply).

2. Identification and assessment of market opportunities for CO2 buffering and water recovery using adsorbents in Greenhouse Horticulture

3. Consortium building with business partners interested in the market opportunities for the follow-up Innovation project: a demonstration with a prototype installation at a commercial greenhouse to make the technology market ready
