The farmer-owned cooperative will use Topsoe’s HydroFlex technology to produce renewable diesel, with production expected to begin in 2025
Topsoe, a leading global provider of advanced technology and solutions for the energy transition, has been chosen as the renewable diesel technology partner for CountryMark’s Mount Vernon refinery in Indiana.
The refinery, located in southwestern Indiana, processes 35,000 barrels of crude oil per day. With the integration of Topsoe’s HydroFlex technology, CountryMark plans to produce up to 250,000 barrels of renewable diesel annually. This new unit is expected to reduce emissions by approximately 84,500 tons of CO2e each year — equivalent to removing emissions from over 186,000 commercial truck roundtrips between Indianapolis and Washington D.C.
CountryMark, a farmer-owned cooperative, will use locally sourced soybean oil as the primary feedstock to produce renewable diesel, supporting the development of a locally based renewable fuel economy in Indiana.
Since 2010, HydroFlex has been a proven technology for producing renewable fuels and sustainable aviation fuel (SAF).
