Atmospheric Carbon-to-Protein Synth is a technology that converts carbon dioxide (CO2) and electrical energy directly into edible protein powders, addressing the challenge of sustainable food production.
It addresses the global challenge of food security by providing an alternative method of protein production that does not rely on traditional agricultural practices, thus potentially alleviating pressure on land use and water resources.
The process involves using hydrogen-oxidizing bacteria to consume electrolysis-derived hydrogen, which in turn uses CO2 as a carbon source for protein synthesis. The electricity required for this process is used to split water molecules through electrolysis, producing hydrogen gas that serves as the energy carrier and reducing agent.
The manufacturing process involves setting up a facility with electrolysis equipment to produce hydrogen from electricity, followed by bacterial fermentation tanks where the hydrogen-oxidizing bacteria synthesize proteins using CO2 as a carbon source.
Construction includes installing large-scale electrolyzers for hydrogen production and fermenters for protein synthesis. The facilities require careful temperature control and sterile conditions to maintain optimal growth of the bacteria.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Overall, the technology requires substantial electrical input for both hydrogen production and protein synthesis.
