Green Gas & Liquids' Nicola Donato: "Ten times less cost than you would have with liquid CO2" Greenhouse operators facing unstable energy markets and unreliable CO2 supply are increasingly turning to on-site carbon capture as a route to cost stability and supply independence, according to Nicola Donato, Business Development Manager at Green Gas & Liquids, speaking at CEA & Indoor Farming 2026. CO2 enrichment is one of the largest levers a greenhouse has over output, capable of increasing crop yields by up to 25 percent depending on radiation levels, CO2 concentration, and the uptake efficiency of the specific crop.
Summer demand from the beverage and food industries reduces availability precisely when CO2 is most critical for plant growth. Capture at night, inject by day Green Gas & Liquids addresses this through its Galloxol post-combustion carbon capture system, which takes flue gas from a CHP, biomass boiler, or gas boiler, conditions and cleans it, and uses a proprietary absorber-desorber cycle to separate and store CO2 in gaseous form at above 99 percent purity.
"You can capture the CO2 at night, when maybe the CHP has most profitability, and inject the CO2 in the morning when it makes most sense," Donato said. "Provided that you really need the heat and you are in an area like the UK, Canada, the Netherlands, or the Nordics, where you are producing the CO2 for heat anyway, in that case it can really go down another magnitude, ten times less cost than you would have with liquid CO2," Donato said.
Why this matters: For operators, this is a water-management story. The useful signal is that direct substrate measurements can help cut drain loss materially without giving up yield or fruit quality, which is exactly the kind of controllable efficiency gain a facility can build on.
Frequently Asked Questions
Why does substrate sensing matter in free-drain strawberry systems?
Because drain percentage tells a grower what already happened, while substrate moisture and EC data show root-zone conditions directly. That makes it easier to cut water loss without guessing.
What is the operator takeaway from this trial?
If the thresholds are understood well enough, growers can reduce drain water materially while protecting yield and fruit quality, which makes sensing an operational tool instead of a reporting tool.
