Haldor Topsoe to support Indaba Renewable Fuels’ production of sustainable aviation fuel

Company's technology to be installed at 2 SAF biorefineries

  • Indaba Renewable Fuels (Indaba) will build two greenfield refineries in California and Missouri to produce Sustainable Aviation Fuel (SAF) utilizing Topsoe’sHydroFlex™ technology.
  • The facilities are expected to begin production of SAF in 2024 totaling. The capacity of the plants is 6500 barrels per day at each location.
  • Topsoe will also provide its H2bridge™ hydrogen technology for both facilities that further replaces fossil fuels with renewable liquids like LPG or naphtha to lower the carbon intensity of the products.

“We are excited to provide Indaba with refining technology and catalysts as they initiate production of renewable fuels in the United States. Our HydroFlex™ solution is designed to produce sustainable aviation fuel (SAF) based on renewable feedstock, with a minimal Carbon Intensity (CI score) compared to traditional petroleum aviation fuel,” says Henrik Rasmussen, Managing Director, The Americas, Haldor Topsoe Inc.

The solution enables Indaba’s facilities to accept a wide variety of feedstocks as well as the production of multiple low carbon Index (CI) renewable fuels.

“We are thrilled to select Haldor Topsoe’s market-leading HydroFlex™ technology for these projects that will enable us to lead the aviation industry’s transition to sustainable and low emissions fuel. These projects will source feedstocks from waste products to create low carbon emission SAF for decades,” says Geoff Hirson, Chief Executive Officer, Indaba Renewable Fuels.

About HydroFlex™ and H2bridge

With HydroFlex™, refiners can convert low value feedstocks to renewable fuels that qualify for Low Carbon Fuel Standard (LCFS) credits. The innovative HydroFlex™ process layout offers lower capital expenditure (CAPEX), but also a lower energy consumption during operation, resulting in a lower Carbon Index (CI).

The H2bridge™ hydrogen technology is based on a modular and highly efficient convection reformer technology. It delivers a circular solution to refineries and biorefineries by replacing fossil feedstocks with renewable LPG or naphtha to produce renewable hydrogen, thereby generating significant greenhouse gas emissions savings and lower the carbon intensity of the renewable fuels produced in the HydroFlex™ unit.

About Indaba Renewable Fuels

Indaba Renewable Fuels LLC (Indaba) is a US-based waste-to-renewable fuels company that converts plant and animal oils, fats, and grease-based feedstock into Sustainable Aviation Fuel (SAF). Indaba will use a patented and proven technology platform—which provides the most environmentally clean and economically efficient renewable fuels production. Indaba is constructing a new renewable fuel refinery in both California and Missouri that will produce high grade, low carbon footprint, ultra-low sulfur “drop-in” jet fuel. Opening in 2024, these plants will set a new industry standard for sustainable fuel generation.

Indaba’s mission is to deliver renewable fuel solutions in a way that is environmentally clean, economically efficient and sustainable long-term.
