Inside the Technology

Structural components & key features of Carbon-to-Food systems

Carbon-to-Food systems integrate carbon capture, renewable energy, microbial engineering, and industrial-scale fermentation into a vertically integrated bioprocess that converts atmospheric or point-source CO₂ into protein-rich food ingredients — decoupling food production from arable land, freshwater, and seasonal growing conditions.

Hydrogen-oxidizing bacteria (HOB)
Chemolithotrophic microorganisms — primarily Knallgas bacteria such as Cupriavidus necator (formerly Ralstonia eutropha) — that use hydrogen as an electron donor and CO₂ as a carbon source to synthesise biomass rich in protein (60–70% dry weight), essential amino acids, and micronutrients. HOB are the primary biological chassis for carbon-to-food systems, requiring only CO₂, H₂, O₂, and mineral salts to produce high-quality single-cell protein without organic feedstocks.
Gas fermentation bioreactors
Pressurised stirred-tank, loop, or bubble column bioreactor systems engineered to maximise CO₂, H₂, and O₂ mass transfer to microbial cultures — the primary technical bottleneck in HOB and gas fermentation scale-up. Advanced reactor designs with optimised gas sparging, agitation, and pressure management enable the high volumetric productivities required for economically competitive protein production at industrial scale.
Engineered microbial strains
Synthetic biology and metabolic engineering approaches that enhance wild-type HOB and other CO₂-fixing microorganisms — accelerating CO₂ fixation rates through RuBisCO and Calvin cycle optimisation, improving amino acid profiles for food functionality, enabling production of specific high-value proteins or lipids alongside bulk biomass, and increasing tolerance to industrial bioreactor conditions including elevated CO₂, O₂, and temperature.
Precision fermentation & product diversification
Microbial expression systems that produce specific functional food proteins — casein, whey proteins, egg albumin, or novel designer proteins — using CO₂-derived carbon as the feedstock rather than conventional sugar substrates. Precision fermentation on carbon-derived media enables production of high-value food ingredients with defined nutritional and functional properties beyond bulk protein, expanding the commercial value proposition of carbon-to-food platforms.
Renewable hydrogen production integration
Green hydrogen generated by renewable-electricity-powered water electrolysis serving as the energy carrier and electron donor for HOB fermentation — closing the carbon and energy loop between renewable power generation, water splitting, microbial CO₂ fixation, and food ingredient production. The cost and availability of renewable hydrogen is the primary determinant of carbon-to-food system economics and the key coupling between the energy transition and sustainable protein production.
Carbon capture & CO₂ supply systems
Point-source CO₂ capture from industrial emitters — power plants, cement kilns, steel furnaces, fermentation facilities — or direct air capture systems providing the carbon feedstock for microbial fermentation. Integration with industrial CO₂ sources enables carbon-to-food systems to simultaneously reduce atmospheric carbon emissions and produce sustainable protein, creating a dual environmental value proposition that supports circular economy and industrial symbiosis strategies.
AI-driven bioprocess optimisation
Machine learning models and reinforcement learning systems trained on bioreactor sensor data — dissolved gas concentrations, pH, optical density, temperature, and metabolite profiles — that autonomously optimise fermentation conditions to maximise protein yield, quality, and energy efficiency. AI bioprocess control closes the optimisation loop between carbon feedstock supply, energy input, and protein output, enabling continuous improvement of carbon-to-food system performance without manual intervention.
Downstream processing & food ingredient formulation
Cell harvest, concentration, drying, and purification processes that convert microbial biomass from the bioreactor into food-grade protein ingredients with defined texture, flavour, colour, and nutritional profiles — including whole-cell single-cell protein, protein isolates, protein concentrates, and functional ingredient formats designed for integration into meat analogues, dairy alternatives, protein beverages, and animal feed products.
Challenges addressed

Why conventional food production systems cannot meet the sustainability, resilience, and scale demands of a growing world

Carbon-to-Food technology directly targets five fundamental constraints of conventional agricultural protein production that limit the food system's ability to feed a growing global population within planetary boundaries — constraints that incremental improvements to conventional farming and aquaculture cannot resolve.

01
Agricultural land use pressure and deforestation
Global protein demand is projected to increase by 50–70% by 2050 — a requirement that cannot be met by expanding conventional agriculture without further deforestation, biodiversity loss, and land competition with carbon sequestration. Carbon-to-food systems producing protein in vertical bioreactors require orders of magnitude less land per kilogram of protein than soy, livestock, or even insect farming — potentially producing global protein requirements on a land footprint orders of magnitude smaller than current agriculture
Land Use
02
Freshwater consumption in food production
Agriculture accounts for approximately 70% of global freshwater withdrawals — a share that becomes increasingly unsustainable as aquifer depletion, glacial retreat, and changing precipitation patterns reduce freshwater availability in the world's major crop-producing regions. Carbon-to-food fermentation systems require only the water incorporated into microbial biomass and process cooling — consuming a fraction of the water required per kilogram of conventional plant or animal protein and decoupling food production from freshwater resource constraints
Water
03
Greenhouse gas emissions from conventional protein production
Animal-derived protein production generates 14.5% of global greenhouse gas emissions through enteric fermentation, manure management, land use change, and feed crop cultivation. Even plant-based protein production contributes significant nitrous oxide emissions from fertilizer application. Carbon-to-food systems powered by renewable energy and using captured CO₂ as feedstock can achieve net-negative lifecycle GHG emissions — actively removing carbon from the atmosphere while producing protein — creating a fundamentally different environmental profile versus any form of conventional agriculture
GHG
04
Supply chain fragility and geographic constraints
Conventional food systems are concentrated in a small number of geographic regions with specific climatic conditions — making global food security vulnerable to regional climate disruption, geopolitical instability, crop disease, and extreme weather events. Carbon-to-food bioreactors can be deployed at virtually any location with access to renewable electricity and CO₂ — including urban environments, arid regions, polar locations, offshore platforms, and space — enabling distributed, climate-independent food production that dramatically increases supply chain resilience and food sovereignty
Resilience
05
Nitrogen fertilizer dependency and ocean dead zones
Conventional protein crop production depends on Haber-Bosch synthetic nitrogen fertilizer — a process consuming approximately 1–2% of global energy and generating substantial N₂O emissions. Excess nitrogen application creates agricultural runoff that causes eutrophication and hypoxic dead zones in coastal waters worldwide. Carbon-to-food microorganisms fix atmospheric nitrogen or utilise mineral nitrogen with high efficiency at the point of protein synthesis — eliminating the field-scale nitrogen application and runoff that drives agricultural eutrophication
