A clean-energy startup developing a reactor that converts carbon dioxide into a charcoal-like substance secured $85,000 for winning the MN Cup, the nation's largest statewide innovation competition.
Carba's reactor removes carbon dioxide from the air and buries the solid carbon beneath the earth's surface to reverse the effects of coal mining, abandoned mines and quarries, and remediate landfills.
There's a correlation between climate disasters — like wildfires and rising sea levels — and climate warming too much carbon dioxide in the atmosphere causes, chief executive and co-founder Andrew Jones said. It's reaching the point where humans won't be able to reverse damage to the atmosphere if they don't address it in the coming years.
"Two-and-a-half years ago when I started this, I said, 'Why have we not moved further in carbon dioxide removal?'" he said, adding he first learned about it a decade ago when studying at UC Berkeley. "It was kind of, 'OK, the technology is ready, but are we going to do this?' Fast-forward to today, and very few credits have been delivered. I felt the need to try it myself. There wasn't enough being done."
Carba is selling forwards, or future sales, Jones said. Those will serve as carbon credits, something companies acquire to offset some of their own carbon dioxide emissions, co-founder Linda Hofflander said.
Carba's goal is to remove 1 billion tons of carbon dioxide from the air by 2035. It's ambitious, but on a global scale, pales in comparison to the 10 billion tons of carbon dioxide that needs removal per year by 2050, he said.
"We really need to get some of these milestones to be on track for that," Jones said. "If by 2036 we don't do anything, we're going to hit 2 degrees of warming, and that's going to hit some of these tipping points where it's really hard, if not impossible, to go backwards."
Carba will apply the prize money to research and development as well as hiring to enable the company to grow from a 1 carbon-ton per day facility to a 45-ton per day facility, Jones said. The company, which has closed on funding from angel investors and is raising seed capital from private investors, will move later this year from Litchfield to Burnsville, next to a landfill and compost facility.
