Applications: CO2 to Chemicals


Sustainable Innovations’ CO2RENEW™ provides a completely new way of producing valuable commodity chemicals and fuels from waste greenhouse gases, generating needed hydrocarbon products on-site, eliminating transportation and storage costs. CO2RENEW™ can convert waste CO2 to carboxylic acids such as formic acid, oxalic acid, acetic acid, lactic acid, and others, providing important feedstocks for the production of certain polymers. Examples of typical carboxylic acid use:

  • In the production of polymers (maleic and terephthalic acids, etc.)
  • In beverages (citric acids)
  • As chelating agents (ethylenediaminetetraacetic acid)
  • In coatings (fatty acids)
  • As food preservatives (propionic acid)

Formic Acid – Formic acid is a simple carboxylic acid with the chemical formula of HCOOH (CH2O2). Its value as a recycled CO2 product shows promise for two reasons. First, the ratio of market value to cost of production is high because of the relatively low electricity input that is required for the manufacture of formic acid from CO2. Second, formic acid has an as yet untapped market potential as a hydrogen energy carrier that can be used as a fuel for fuel cells.
