On a surface look, probably it works. Maybe things like nitrate/phosphate balance or pest/microbe control impact the long term production.

The problem, as with all CCS strategies is: how do you pay for it? Maybe you can sell those products for a rate that covers the labour and wear and upkeep of the system? It might just be more cost effective to take the carbon-free energy and use it to displace fossil fuel consumption...

Master Plan: Agrivoltaic Azolla Cultivation (Simplified)

A practical, low-cost system that uses solar panels and floating water ferns (Azolla) to capture carbon and generate profitable products.

The 4-Step System Loop

1) Shallow Clay Ponds

• Setup: Dig flat, shallow trenches (~10 m wide) lined with local clay.
• Water depth: Keep at 5–10 cm to minimize weight and water use.
• Flow: Use gravity and simple plastic gates to slowly drift ferns toward the harvester.

2) Solar Panel Canopy (Agrivoltaics)

• Shade: Mount solar panels to block 40–50% of harsh midday sun, reducing fern sunburn.
• Cooling: Pond evaporation cools panels, improving efficiency by up to 12%.
• Power: Panels generate 100% of facility electricity.

3) Automated Squeeze Loop

• Skim: Automated paddle wheels continuously collect grown ferns.
• Squeeze: High-torque electric screw press reduces moisture from ~95% to ~50%.
• Recycle: Nutrient-rich juice is piped back into ponds, recycling ~90% of fertilizer.

4) Solar Drying & Final Products

• Dry: Sun-dry squeezed biomass in simple plastic tunnel greenhouses.
• Outputs:
  • Biochar: Bake dry fern without oxygen to lock carbon away.
  • Animal feed: High-protein dry ferns for livestock and fish feed.
  • Fertilizer: Pelletized fern to replace synthetic nitrogen fertilizer.

Estimated Yearly Yields (Per 1 Hectare Pilot)

• Solar energy: ~600,000 kWh clean power
• Biomass: ~35–40 tons dry Azolla
• Carbon captured: ~110 tons CO₂e sequestered
• Water & nutrients: 100% recycled closed loop
