Upflow, a New Zealand geothermal consultancy, is spearheading an innovative project potentially revolutionising how we produce food using geothermal gases. With nearly $5 million in funding up its sleeve, Upflow is developing, in the first instance, a high-protein livestock feed by converting waste CO2 and methane from geothermal emissions into valuable biomass.

This innovative approach, conducted in collaboration with Rotorua based, Scion, the University of Canterbury, and algae experts from Cawthron Institute, utilises a bacterium and algae symbiosis to transform greenhouse gases into protein-rich feed. The process not only promises a sustainable animal feed source but could also pave the way for similar technologies in human food production.

The project aligns with New Zealand's goals to decarbonise its economy and could create new job opportunities in the regions at the same time helping the country meet its climate targets. If successful, this four-year venture could lay the groundwork for a new industry, projected to be worth $500 million annually by 2045, providing a renewable and eco-friendly solution to food production challenges.
Upflow's initiative stands out as it offers a scalable model adaptable for human food production, leveraging geothermal resources to provide heat, electricity, and carbon dioxide in a closed-loop system minimising environmental impact.
This project is not just about creating sustainable feed; it's a step towards a future where human food production is intertwined with energy innovation and sustainability.
