How the technology works


Step 1

Captured CO₂ into Proton™, a single-cell protein optimised for animal feed via proprietary gas fermentation process

Step 2

Co-develop Proton™-based feeds with market leading feed producers

Step 3

Produce sustainable animal products with up to 60% less greenhouse gas emissions (throughout total value chain)



  • Captured CO2 is fed into the containerised Deep Branch mobile unit
  • CO2 and hydrogen used as respective carbon and energy sources in fermentation process
  • Fermentation run continuously, providing far greater productivity than traditional batch processes
