Profitably Reducing Emissions

Our two biorefineries currently under construction will produce over 150 Million gallons per year of Renewable Diesel.  This saves more than 2 billion pounds of CO2 from being emitted each year. That's the equivalent of removing over 250,000 vehicles from the road.

Our Superior Technology Makes it all Possible

Ryze has developed a state-of-the-art hydrotreating technology that is more efficient and has a lower carbon footprint than traditional Renewable Diesel production methods.  Our technology can process a wide variety of inedible agricultural oils and animal fats, which ensures the consistent production of high quality renewable fuels from the most economical and environmentally sustainable feedstocks available.

A More Advanced Process

Renewable Diesel is made by adding hydrogen to natural fats and oils. Our process introduces the hydrogen in a more efficient manner, allowing the reactor temperatures to be uniform and controlled. This increases yield, lowers operating costs, and allows for feedstock flexibility.

The Chemistry

The technology Ryze is deploying in the Reno and Las Vegas facilities is a relatively simple chemical reaction that involves adding hydrogen (hydrogenation) to agriculture oils and animal fats.  Eco-friendly Renewable Diesel chemical process All oils and fats are triglycerides, consisting of three fatty acids (hydrocarbon chains) connected by a glycerin. The main difference between fossil-fuel hydrocarbons and triglycerides is the presence of oxygen atoms in the glycerin.  To remove the oxygen, the triglycerides are hydrogenated in the presence of a catalyst. Hydrogen removes the oxygen from the molecule (deoxygenation) by forming H2O. This results in three straight-chain diesel molecules (C18H38), six water molecules (H2O), and one propane molecule (C3H8) for each triglyceride molecule that was hydrogenated.  Straight-chain diesel molecules from triglycerides have a high melting point and must be isomerized (re-arranged) to improve their cold-flow properties. After the isomerization, the diesel can be used by any diesel engine as a drop-in Renewable Diesel.  We have developed the most efficient and cost-effective method of hydrogenating triglycerides to produce Renewable Diesel.

The Future of Renewable Diesel

Our facilities in Reno and Las Vegas have created over 500 construction jobs and will create more than 140 full time positions once operational and producing over 11,000 barrels of Renewable Diesel per day.  This capacity is only a fraction of what is needed – the demand for Renewable Diesel in California alone is expected to exceed 150,000 barrels per day. We have additional projects under development that will expand our total capacity to meet this demand over the next 10 years.

A Better Fuel

• Our fuel is produced from inedible waste streams of agricultural oils and animal fats. In other words, we make fuel from the carbon that plants pull out of the air, instead of from oil in the ground.
• Unlike biodiesel, Renewable Diesel is a pure hydrocarbon chain that is superior to fossil diesel. The high Cetane (80+) of our fuel delivers more power to the engine with noticeably increased mileage compared to standard diesel.
• As a "drop-in" fuel, Renewable Diesel is molecularly equivalent to fossil diesel and has no blending limit. It is fully compatible with existing fuel distribution infrastructure without the need for additional investment.
• In addition to being renewably sourced, Renewable Diesel burns cleaner than fossil diesel by combusting more completely. This significantly reduces total hydrocarbon, particulate matter, carbon monoxide and nitrogen oxide (NOx) emissions.
