Idea description

Deep Branch is a British company which converts carbon dioxide into protein for animal feeding.

The patented (R)evolve gas fermentation platform uses carbon dioxide and hydrogen as clean and renewable sources of carbon and energy to create ingredients for a more sustainable food system.

Clean and sustainable carbon dioxide and hydrogen are fed into our fermentation vessel along with a handful of simple nutrients. Proton is grown using naturally occurring microbes in a continuous natural fermentation process that effectively reduces emissions from agriculture, and becomes the optimal macro ingredient in the harvesting and drying process.


  • Bioengineering food production


Deep Branch startup processes industrial CO2 emissions into high-quality single-cell protein (Proton), optimized for animal feeding. For this purpose, the scientists use special microorganisms.
