Calgary-based Vault 44.01 recently submitted two applications with the EPA for carbon sequestration well permits in Indiana.
The firm, which is owned by Grey Rock Investment Partners, submitted applications for one well in each of Madison and Wabash counties, according to the EPA website.
Vault has entered into various CCS arrangements with emitters in the U.S. Midwest, including with Cardinal Ethanol in Indiana and Alto Ingredients in Illinois. The company filed its first Class VI application in 2023 for a one-well site, also in Indiana.
Grey Rock took a controlling stake in Vault in 2022 along with a $150m commitment to find its CCS project development pipeline.
As of 2022, Vault had a pipeline of projects with the potential to capture and store up to 25 million metric tonnes of CO2 per year. Its website currently states that it has over a dozen projects in the US Midwest, US Gulf Coast, and Canada in various stages of development.
