Geothermal emissions of methane and CO2 could soon be put to good use. 

Work is underway in Rotorua to create livestock feed from the gasses in world-first research that could net the country $500 million by 2045. 

The feed would be created from protein rich biomass, produced when microorganisms feed off greenhouse gas emissions captured from geothermal power stations. 

Upflow Business and Innovation Director Andy Blair told Mike Hosking that they’re testing if the system is scalable, to see how they can make it economically viable and sustainable for the commercial market. 

The feed is unlikely to be bulk food, he said, but additives instead, since it’s not a cheap thing to produce.
