The project is dedicated to capturing carbon emissions to develop high-quality animal-free proteins using naturally occurring microbes and industrial biotech.
The microorganisms growing use carbon dioxide as a fuel source, but rather than getting the energy for the reaction from sunlight they rely on the chemical energy in hydrogen to power the process. The hydrogen can come from a variety of sources, including industrial waste streams or electrolysis, which is the splitting of water into its constituent parts. Depending on how NovoNutrients obtains the hydrogen, the entire process of creating the nutrients might be able to capture more carbon dioxide than it emits
