Haldor Topsoe A/S (Topsoe), a global leader in high-performance catalysts and proprietary technologies for the chemical and refining industries has announced that it has been selected by US-headed independent petroleum refiner and marketer HollyFrontier Corporation (HollyFrontier) to supply its Topsoe’s HydroFlex solution for HollyFrontier's planned renewable diesel unit (RDU) at its Navajo Refinery in Artesia, New Mexico.

Under the agreement with Artesia Renewable Diesel Company LLC, a subsidiary of HollyFrontier, Topsoe will license and supply basic engineering, proprietary equipment, catalysts, and technical services. The project is based on HydroFlex, a world-leading, industry-proven Topsoe technology that produces renewable fuels, such as gasoline, diesel and sustainable aviation fuel (SAF), from all renewable feedstocks.
The contract was awarded after an in-depth feasibility study, involving competing technologies.
We are very proud that a market leader such as HollyFrontier has chosen HydroFlex for its strategic expansion into renewable fuels. HydroFlex is the preferred choice for refiners leading the industry transition into producing renewable fuels, said Henrik Rasmussen, Vice President of Haldor Topsoe.
Every year, in accordance with the Renewable Fuel Standard (RFS), the US Environmental Protection Agency (EPA) sets an annual quota (Renewable Volume Obligation – RVO) for how much biofuel must be blended into gasoline and diesel sold in the US market.
Renewable Identification Number (RIN) credits represent a volume of biofuel blended into fossil fuel and are used to ensure compliance with the quota. RIN credits can be traded, so companies that do not produce renewable fuels can buy RIN credits to meet their individual quota of renewable fuel.
