  • The farmer owned cooperative, will use Topsoe’s HydroFlex® technology to produce renewable diesel.

  • Production is expected to begin in 2025.

Topsoe, a leading global provider of advanced technology and solutions for the energy transition, has been selected as the renewable diesel technology partner for CountryMark’s Mount Vernon, Indiana refinery.

Located in southwestern Indiana, the refinery processes 35,000 barrels of crude oil per day. With the addition of Topsoe’s HydroFlex technology, CountryMark aims to produce up to 250,000 barrels of renewable diesel annually. The new unit is expected to enable an annual emission avoidance of approximately 84,500 tons of CO2e – the equivalent of eliminating emissions from more than 186,000 commercial trucking roundtrips between Indianapolis and Washington D.C.

CountryMark, a farmer-owned cooperative, will utilize local soybean oil as the primary feedstock to produce renewable diesel, helping create a locally sourced renewable fuel economy in Indiana.

Henrik Rasmussen, Managing Director of Topsoe Americas, said:
“Our collaboration with CountryMark goes back many years. With demand for renewable diesel continuing to grow, we’re excited to partner with CountryMark on their journey to produce cleaner fuels and contribute to America’s low-carbon energy future.”

Matt Smorch, CountryMark President and CEO, added:
“We saw this as an opportunity to deliver increased value to CountryMark diesel fuel buyers, increase the demand for Indiana agricultural products, and add value to our refining assets.”

Since 2010, HydroFlex has been a proven technology for the production of renewable fuels and sustainable aviation fuel (SAF). Renewable fuels offer an efficient, commercially scalable pathway to reduce emissions associated with hard-to-abate sectors like heavy-duty transport and aviation. According to the US Energy Information Administration (EIA), US renewable diesel consumption reached 3.1 billion gallons in 2023. Renewable diesel now accounts for over 5% of total US diesel demand - and that share is expected to grow.
