Energy Use by Production Stage
The energy demands in cultivated meat production differ significantly across various stages, and understanding these differences is key to improving efficiency and cutting costs. Below, we delve into the energy requirements of two critical aspects: bioreactor operation and media production.
Bioreactor Power Requirements
Bioreactors are among the most energy-hungry elements in cultivated meat production. Maintaining precise conditions - like temperature, oxygen levels, and sterility - requires substantial energy input. In fact, studies reveal that cooling systems and environmental controls account for nearly 75% of a facility's energy consumption.
For example, a 100-litre bioreactor (costing about £80,000) demands significant power to regulate temperature, circulate oxygen, and ensure sterilisation. Larger air-lift reactors, with capacities exceeding 20,000 litres, are designed to improve mixing efficiency while lowering energy use and minimising shear stress.
"The survey underscores the critical need for ongoing innovation and investment in bioprocessing technologies to enable the cultivated meat industry to scale efficiently. It identified specific areas where suppliers, manufacturers, and researchers can accelerate the industry's expansion and reduce production costs." - GFI Report
Media Production Energy Costs
Cell culture media production is another energy-intensive stage, with serum-free media (SFM) accounting for at least 50% of variable operating costs. For certain formulations, like Essential 8 medium, nearly 98% of costs are tied to growth factors and recombinant proteins.
Recent advancements have significantly lowered SFM costs. For instance, Believer Meats has achieved production costs of approximately £0.50 per litre by optimising components and using innovative processing techniques. Research also shows that substituting pharmaceutical-grade media components with bulk, food-grade alternatives can slash production costs by up to 77%. To illustrate, food-grade glucose costs around £0.85 per kilogram, compared to £77 per kilogram for its pharmaceutical-grade counterpart.
Efficient media management plays a vital role in large-scale operations. Upside Foods, which runs the largest cultivated meat facility, produces approximately 22,680 kg annually. These examples highlight the importance of energy and cost optimisation in media production to make cultivated meat more viable and scalable.
