Discover how your business can stabilise CO₂ enrichment across different zones, simplify daily operations, and minimise transport risks by capturing CO₂ on-site and conditioning it for safe use in greenhouses through Carbon Capture and Utilisation (CCU).
How It Works
Step-by-step
On-site capture turns CHP/boiler exhaust into a crop-safe CO₂ utility that follows sunlight/LED cycles. The steps below show how the unit conditions, captures and doses CO₂ reliably across zones.
Source the CO₂ (boiler/CHP/exhaust)
We tap the flue line from your boiler or CHP and route it to the capture train. Inlet sizing matches your temperature, flow and sulphur/chloride load for stable downstream operation.
Quench & condense (protect dosing lines)
Controlled quench drops temperature; condensers remove moisture and acid vapour, with demisters cutting droplets and dust—keeping pipes, valves and greenhouse dosing lines clean.
Absorb CO₂ (closed-loop, food-safe)
Galloxol® selectively absorbs CO₂ and rejects non-CO₂ gases. The biodegradable solvent has zero vapour pressure, so there’s no solvent carry-over—critical near food crops.
Regenerate & buffer (ready to inject)
Regeneration releases high-purity CO₂, then a compact gas buffer holds a few hours of inventory. Capture when economical (often at night) and inject by day when photosynthesis peaks.
(Optional) Liquefaction & compact storage
Where footprint is tight or multiple bays need supply, liquefaction condenses CO₂ to liquid for small, centralised tanks and predictable inventory across seasons.
Distribute & dose in zones
We tie into zone valves and controls. Dosing follows PAR/LED profiles to hold ppm set-points and curtails when vents open—maximising effect while reducing losses.

This visual guide walks you through each phase, showing how we turn concepts into results.
Yield impact
Up to 20% Higher Yield
Dose when plants can use it. By capturing CO₂ on site and buffering a few hours, you can inject precisely during high-radiation and LED blocks, when photosynthesis peaks. That timing (not just total tonnes) is what drives results, enabling up to ~20% more yield with stronger colour and grading. Typical set-points sit around 150 – 300 kg/ha·h, adjusted to crop and light.
The Galloxol® solvent delivers ≥99% purity with zero vapour pressure, so there are no solvent traces in the CO₂ at canopy level, safe around food crops and simple for QA. Run CHP/boilers when power prices make sense, store the CO₂, and dose by day to turn energy into consistent growth.
Unique Selling Points
Key Advantages
Galloxol® delivers greenhouse-grade CO₂ (≥99% purity) with zero solvent carry-over, thanks to a biodegradable solvent with zero vapour pressure and heat-integrated design. Choose LOW-temp (≈95 °C) or HIGH-temp (≈140 °C) trains to match your utility network; both are built to run with low OPEX and plug into existing dosing lines.

Benefits
Benefits of Galloxol® in Horticulture
CCU increases self-reliance in summer, reduces delivered CO₂ cost far from liquefaction hubs, stabilises €/kg produce under inflation, and can even creates new revenue from selling clean CO₂ to nearby users, while enabling higher yield and quality with consistent dosing.
Secure supply in summer
Summer is when enrichment drives the largest growth response, yet liquid CO₂ is scarcest because F&B demand peaks. On-site CCU makes you self-reliant: you capture CO₂ locally, store a few hours, and dose exactly when photosynthesis peaks, matching supply to radiation instead of truck schedules.
With a short-term buffer you can run CHP/boilers when electricity prices make sense (often at night) and inject by day when plants actually need CO₂. That removes the seasonal cap on growth and keeps your agronomy plan stable across heatwaves and delivery hiccups.
Lower delivered CO₂ cost
If you’re far from a CO₂ liquefaction hub, each tonne carries transport premiums, liquefaction power cost and an embedded footprint. On-site capture cuts long-haul charges and volatility, so €/t CO₂ becomes both lower and more predictable.
Because Galloxol® is energy-efficient (heat-integrated) and has no solvent losses, OPEX stays structurally low, so your “delivered” CO₂ cost converges toward on-site production cost, not market spikes.
Reduce cost per kg produce
Energy, labour and logistics inflation push purchased CO₂ upward. Replacing a share with on-site CO₂ dampens exposure to fossil price, liquefaction electricity and trucking, stabilising €/kg produce across the season.
Galloxol®’s solvent has zero vapour pressure and is biodegradable, enabling greenhouse-grade CO₂ without costly downstream polishing. Fewer unit ops + high thermal efficiency → lower, steadier OPEX that compounds across many dosing hours per year.
Sell the surplus
In shoulder seasons or when dosing windows are short, captured CO₂ can exceed greenhouse demand. Where permitted, surplus can be sold to nearby users, turning your site from a net buyer into a mini CO₂ hub.
Typical off-takers include food & beverage, dry-ice or process users. Because the CCU CO₂ is clean and consistent, the same stream can be directed to enrichment or external uses depending on daily needs, improving payback.
More yield, better quality
With dosing aligned to radiation/LEDs at ~150 – 300 kg/ha·h, greenhouses can achieve up to ~20% higher yield alongside better colour and grading, provided CO₂ is present at the right minute, not just the right day.
The product CO₂ is greenhouse-grade (≥99% target) and free of solvent carry-over, Galloxol® has zero vapour pressure, so there are no solvent traces in the CO₂ you inject near food crops. That keeps enrichment safe and QA simple.

All frequently asked questionsYes. The platform is modular: add capture trains, storage and distribution capacity as you scale. This avoids stranded assets and keeps capex releases tied to yield.
We’ll model energy, seasonality and enrichment windows so expansions remain efficient and predictable.
Most growers begin with a gaseous buffer. You can add CO₂ liquefaction later to concentrate storage or feed multiple houses from a compact tank, depending on acreage and layout.
We align capture supply with light hours and vent strategy to minimise losses and stabilise ppm, a practical way to turn carbon capture into consistent agronomic benefit.
Yes. Dosing follows your climate schedule so ppm is delivered when plants can use it, and curtailed when vents open to limit loss. Controls integrate with your EMS/EMS-like system.
This makes on-site CO₂ recovery a reliable input to yield planning rather than a variable to manage daily.
