Project 1 - AB Farms


C3 is currently working with an East of England fish & agriculture farm to develop sustainable aquaculture and enhanced natural food production systems.

The aim is to set up a system on land and/or floating structures that will provide fresh fish and vegetables NOT contaminated with chemicals and pesticides whilst delivering a carbon-zero-growth environment, utilising natural accelerated-growth technology to deliver increased single - or multiple annual - yields in both fish and vegetables.

Technologies being deployed
  • Solar PV
  • Static & Mobile Aeration units
  • Nutrient-Enhanced Diatom Water Remediation
  • Electro Water System (EWS) technology
  • Hydroponics
  • Algal Biomass
Deployment Methodology & Timelines
Stage 1: Solar PV (no planning approval required for this project). The solar PV will reduce production costs and will provide a small cash flow from the Feed-in-Tariff initially. Aeration will be provided by the in situ aeration system run by the solar PV.
Stage 2: EWS will also be powered by the Solar PV to clean and remediate water for reuse within a closed loop system to minimise the need to draw large amounts of water and minimising the need to discharge.
Stage 3: Incorporate hydroponic system using the waste water to grow on site fish feed. Dependent on size planning permission may be required for hydroponic systems.
Stage 4: Develop Algal Biomass using the waste water to provide additional on site power needs and further cash flow from the Renewable Heat Incentive.
Stage 5: Develop Research & Training facilities to further develop sustainability the technologies for fish farming and increased crop production. Research will focus on developing aquaculture production for sustainable communities with climate change being a central consideration. Use facilities at Cambridge University to replicate weather conditions and patterns.

Time lines: Stage 1 will be up and running within 6 weeks of funding disbursement. All subsequent stages will follow immediately, limited only by hardware manufacturing/supply schedules.

Technology Performance:
The farm currently circulates 33,000 m3 of water per hour and this might have to increase if more fish are cultured, which is the plan. The EWS will be designed for required system capacity so, for example, the CLEAN-FRAC 300K (designed to remediate oil polluted water) can remediate 1.15 million litres per day.

Since there is a blend of deliverables envisaged in this contract, variable remediation volume rates may be required. This is easily managed since EWS units are mobile, sitting on a short trailer and capable of being towed by a mid-size family saloon car. So flow rates can be adjusted and the unit(s) can be sited where they are needed at a momentís notice, whether this is outdoors or indoors.

Nutrient enhanced diatoms - ranging in size from about 2 microns to about 500 microns - will be deployed not only to alleviate the need for extensive aeration but also to provide significantly enriched feed material to deliver accelerated fish growth rate and size.
