Renewable Fuels for a Sustainable Future
Utilizing renewable feedstocks provides a sustainable alternative to traditional, non-renewable resources such as petroleum. These feedstocks offer lower life cycle emissions compared to petroleum-based diesel without sacrificing performance.

Sustainable Aviation Fuel (SAF) is a combination of synthetic paraffinic kerosene (SPK) and conventional jet fuel. SPK is designed to reduce the life cycle emissions of the aviation industry’s carbon footprint. It is made from sustainable, renewable feedstocks and agricultural byproducts such as tallow, distiller corn oil, canola oil, and camelina oil, and has lower life cycle emissions compared to conventional jet fuel.

Renewable Hydrogen
Renewable Hydrogen — also known as “green” hydrogen, is produced by splitting water into hydrogen and oxygen. Montana Renewables is constructing a new hydrogen plant that will collect the hydrogen gases from our Renewable Diesel reactor and recycle the hydrogen for reuse within the facility using a technology currently patent pending.
