A startup from Quebec is using an electrochemical process to produce potassium formate from CO2.

Their process for generating potassium formate is greener than standard methods. It does require electricity as an input but that can come from renewable, green sources.

Potassium formate is used in de-icing products, fertilizer, heat transfer fluids, drilling fluid, etc... so a useful, monetizeable output comes out of the process.

Disclosure - Know the founders personally. Wanted to shoutout their work. No financial ties to the company.Chemistry is not at all my expertise & I don't have details on their process beyond what's on the website.
