An ethanol plant in Indiana has become the latest in the US to seek to decarbonise its operations through the use of carbon capture and storage (CCS).

Canada-based CCS project developer Vault 44.01 is partnering with the ethanol maker, Cardinal Ethanol, on an early to market CCS project in Randolph County. A joint venture between the companies, called One Carbon Partnership LP, has sought permit from the US Environmental Protection Agency (EPA) to drill a Class VI well to store carbon dioxide (CO2) from Cardinal’s ethanol plant under the ground, reported S&P Global in January. 

The US supports carbon capture via tax credits, which were expanded by the recent Inflation Reduction Act and provide up to USD 85 per tonne of captured and stored CO2, the article notes.

In the US Midwest there are also at least three proposed pipeline projects aimed at moving the ethanol industry to net zero by taking the CO2 emissions of ethanol plants and storing them underground.
